Berliners go to the polls on Sunday in a state election dominated less by the usual national arguments over migration and foreign policy than by a question that reaches into almost every household in the German capital: who can still afford to live here, and what can government realistically do about it? Housing costs, the shortage of new homes and the future of the vast Tempelhofer Feld have pushed the contest into a wider debate about Berlin’s economic model, the limits of rent regulation and the political price of scarcity. The vote is also a test for Chancellor Friedrich Merz, whose Christian Democrats govern Berlin with the Social Democrats and whose national coalition is already under pressure after a far-right breakthrough in Saxony-Anhalt. Late polling has placed the Left Party narrowly ahead of the CDU, with the AfD in third and the governing parties well short of a clear majority.
A capital election with national consequences
Sunday’s election will choose the 20th Berlin House of Representatives and, at the same time, the district assemblies that shape many neighborhood-level services. The official Berlin election authority says the city issued about 2.4 million election notifications and divided the capital into 78 constituencies. Polling stations are due to open at 8 a.m. and close at 6 p.m. local time, after which broadcasters and polling institutes will publish exit polls and rolling projections before the preliminary official result is assembled. For the first time in a Berlin parliamentary election, 16- and 17-year-old German citizens are eligible to vote, adding a new group of younger electors to a contest already unusually fluid.
The Berlin parliament normally has at least 130 seats, although overhang and compensatory mandates can increase that number. Seventy-eight members are elected directly in constituencies, while the remaining seats are distributed through party lists. The current chamber is larger than the minimum because of the electoral system. The structure matters because Sunday’s result will not simply determine which party comes first. It will determine which combinations can build a majority in a city where five parties are polling comfortably above the threshold and a sixth, the Sahra Wagenknecht Alliance, has hovered close enough to the five-percent barrier to affect coalition arithmetic even if it ultimately fails to enter parliament.
That fragmentation is one reason Berlin’s vote has become nationally significant. The CDU and SPD have governed the capital together since 2023, mirroring the coalition that now governs at federal level under Merz. A decisive rejection of that pairing would not automatically threaten the federal government, but it would strengthen the argument inside both parties that their current political offer is failing in Germany’s largest cities as well as in economically weaker eastern states. Conversely, a respectable CDU result after a bruising summer would give Merz evidence that the party can still compete in a liberal, expensive and demographically diverse metropolis even while the AfD dominates political attention elsewhere.
Housing has displaced the usual campaign script
Berlin’s election has unfolded against a national political backdrop shaped by migration, Russia, Ukraine, energy prices and the rise of the AfD. Yet the capital’s voters have forced housing to the front. Reuters reported ahead of the vote that about 85% of Berlin households rent rather than own their homes, making rental policy a direct household concern on a scale uncommon in many other European capitals. The city estimates that it needs roughly 211,000 additional homes by 2040, while advertised rents have nearly doubled since 2014. That combination has turned questions of supply, tenant protection, planning and land use into the central dividing line of the campaign.
The pressures are visible in official and semi-official market data. Berlin’s 2026 qualified rent index, which covers about 1.6 million relevant apartments and is based on roughly 17,000 rent and property records, puts the general median net cold rent at €7.71 per square metre for the stock covered by the index. That figure is very different from the asking rents faced by people seeking a new home. Investitionsbank Berlin’s 2025 housing-market report put the median asking rent at €15.78 per square metre, more than twice the then-local comparative rent used in the report. For newly built apartments, the median asking rent was just under €20 per square metre. The gap between established tenancies and new listings is politically explosive because it rewards those who can stay put and punishes people who need to move for work, family or space.
The housing shortage is not only a cost-of-living issue. It also affects labor mobility, business recruitment, social services and the city’s cultural economy. Investitionsbank Berlin has warned that a lack of affordable housing can make it harder for employers to attract staff, especially in sectors already facing worker shortages. For a city whose modern economic success has depended on services, technology, creative industries, universities and an influx of younger workers, that is a strategic problem. Berlin can remain economically dynamic only if people who teach, nurse, build, code, serve food, run cultural venues and raise families can find homes within realistic commuting distance of their jobs.
The Left enters election day narrowly ahead
The most striking political development of the campaign has been the rise of the Left Party. A Forschungsgruppe Wahlen poll conducted from September 14 to 17 for ZDF put the Left on 22%, the CDU on 20%, the AfD on 18%, the Greens on 15% and the SPD on 12%, with the BSW at 4%. Polls are snapshots rather than predictions, and small differences between the leading parties fall within normal margins of sampling uncertainty. Still, the broad pattern is clear: the two parties governing Berlin together are not close to a majority on their own, while both the Left and the AfD are substantially stronger than they were in the 2023 repeat election.
The Left has built much of its campaign around the argument that Berlin’s housing crisis is not primarily a shortage that can be solved by loosening planning rules, but a distributional problem that requires stronger public intervention. Reuters reported that the party has promised to increase affordable construction, freeze rents for a year and then cap increases at 1%, push down rents that sit far above the local average, restrict holiday rentals in residential buildings and give social-housing-eligible residents greater access to flats that become vacant in central areas. Its mayoral candidate, Elif Eralp, has also argued publicly for stronger rent ceilings and for using state-owned housing companies as instruments of affordability.
Supporters see that program as a response to a market that has priced ordinary earners out of newly available homes. Critics argue that aggressive controls can protect existing tenants while reducing incentives to build, renovate or put vacant property onto the market. Berlin has already lived through an earlier rent-cap experiment that was struck down by Germany’s Constitutional Court because the state lacked the authority to legislate over an area governed by federal law. The current campaign therefore sits under a legal as well as an economic constraint: any new intervention must be designed around what Berlin can lawfully do itself, what it can do through state-owned companies, and what requires action from the federal parliament.
The CDU’s argument: build more and change the rules
The CDU’s answer begins with supply. Stefan Evers, Berlin’s finance and culture senator and the party’s lead candidate, has argued that the scale of the shortage requires faster construction and a willingness to reconsider politically protected land. The party supports limited housing development on parts of Tempelhofer Feld while preserving a large green core. In campaign material published on the eve of the vote, the CDU said its approach could create room for housing for tens of thousands of people while maintaining a large public open space. The exact delivery timetable would depend on planning, infrastructure and legal changes, but the political message is straightforward: Berlin cannot regulate its way out of a shortage if it refuses to build where land exists.
That argument reflects a broader frustration among developers and economists with the pace of German construction. Investitionsbank Berlin reported that building permits in the city fell below 10,000 apartments in 2024, the lowest level since 2012, even though completions remained around 15,300 that year. Because permits today translate into completed homes only after a long lag, a weak pipeline raises the risk that supply will tighten further. Higher financing costs, construction inflation, planning delays and increasingly complex standards have all weighed on projects. Even where developers want to build, the economics of new housing often produce rents far above what lower- and middle-income households can afford without subsidies.
For the CDU, that is an argument for simplifying approvals, releasing land and encouraging more private as well as public construction. For its opponents, the same facts show why relying on market-rate development is insufficient. The divide is less about whether Berlin needs more homes — virtually every major party accepts that it does — than about who should build them, where they should go, what rents should be charged and how much public money or regulation should shape the outcome. Those questions have made housing policy a proxy for competing visions of the city itself.
Evers is also fighting to stabilize a party that changed lead candidates late in the campaign. Mayor Kai Wegner withdrew as the CDU’s lead candidate in July after criticism of his handling of a January power outage that left large areas of Berlin without electricity for four days. Evers was then chosen to take over the campaign. That late change deprived the CDU of the normal advantage of running an incumbent mayor and forced it to defend both the government’s record and a new leadership offer at the same time.
The SPD fights to remain indispensable
The Social Democrats enter election day in an unusually weak position for a party that governed Berlin for much of the post-reunification era. Their campaign has emphasized affordability, public services, family policy, jobs and a mix of construction with stronger tenant protections. The SPD’s 2026 program argues that new housing and regulation are not alternatives: Berlin needs to build more while also protecting the existing stock and preventing rent abuse. On Tempelhofer Feld, the party rejects housing on the park itself while supporting development on other available sites and around existing structures without building into the protected open space.
The party’s difficulties have been compounded by an investigation involving its lead candidate, Steffen Krach. Reuters reported that police searched Krach’s home and offices as part of an investigation into a health-sector tender process. Krach denies wrongdoing. The existence of an investigation is not evidence of guilt, and no responsible assessment of the campaign should treat it as such. Politically, however, a police search weeks before an election is damaging even when the underlying facts remain contested or unresolved, particularly for a party already struggling to persuade voters that it can deliver competent administration.
The SPD’s strategic hope is that Berlin’s fragmented map still leaves it as a coalition hinge. Even on polling numbers that put the party around 12%, combinations involving the SPD can remain mathematically viable because the CDU, Left and Greens are unlikely to agree easily on a two-party majority, and mainstream parties continue to rule out governing with the AfD. The difference between a historically poor result and a politically relevant one may therefore be whether the SPD is needed to complete a three-party alliance after the votes are counted.
The AfD turns housing into an immigration argument
The AfD’s rise in Berlin has followed the pattern seen across much of Germany, but the party has adapted its message to the city’s dominant concern. It argues that housing scarcity cannot be separated from population growth and immigration, presenting tighter migration policy as part of the solution to pressure on rents, schools and public services. The party also supports limited construction on Tempelhofer Feld. Its opponents reject the attempt to frame the housing shortage primarily through migration, pointing instead to years of underbuilding, high construction costs, land scarcity and the slowdown in permits.
The dispute matters because Berlin is not Saxony-Anhalt. The capital is younger, more international, more service-oriented and more electorally fragmented than many eastern German states where the AfD has made its biggest gains. Yet the party’s polling around the high teens would still represent a major increase from the 9.1% it won in the 2023 repeat election. A result in that range would confirm that the AfD is no longer simply an eastern or rural protest force. It would show that it can consolidate a large vote even in a metropolis where migration is more visible, the electorate is more diverse and progressive parties retain significant support.
At the same time, the AfD remains isolated in coalition terms. Germany’s mainstream parties maintain a “firewall” against governing with it. That makes its electoral strength paradoxical: every additional AfD seat can increase the difficulty of forming a majority without making an AfD-led government more likely. In a five-party parliament, a strong AfD therefore tends to push the remaining parties toward broader and sometimes ideologically awkward coalitions. Berlin could become another example of that pattern on Sunday night.
Tempelhofer Feld becomes the campaign’s physical symbol
No issue captures the argument over scarcity and identity more clearly than Tempelhofer Feld. The former airport, once expanded under the Nazis and later central to the Berlin Airlift, closed to aviation in 2008 and opened as a public park in 2010. In a 2014 referendum, nearly two-thirds of voters supported keeping the field largely free from development. Since then it has become one of Europe’s most distinctive urban open spaces: a vast area used for cycling, skating, running, picnics, gardens, cultural events and habitat protection.
The political question is whether a referendum held in a very different housing market should bind the city indefinitely. The CDU, FDP and AfD support limited development on parts of the field, while the SPD, Greens and Left oppose building homes there and argue that Berlin should first use other available land. CDU supporters say the city cannot declare a housing emergency and simultaneously remove one of its largest centrally located land reserves from consideration. Opponents answer that open space is itself infrastructure in a hotter, denser city and that once public land is developed it cannot easily be recovered.
The debate is not purely symbolic. Building at Tempelhof would require infrastructure, planning changes, public investment and likely years of legal and political conflict. It would not solve the housing shortage quickly. Yet the site matters because it forces every party to state what it values when policy goals collide. Is the priority maximum housing supply, even if it means revisiting a referendum? Is the priority preserving green space and democratic commitments made by an earlier electorate? Or can the city find a compromise that builds on edges while protecting most of the field? Those questions are concrete versions of a wider European urban dilemma.
Berlin is not alone in facing it. Paris, Amsterdam, London, Dublin, Lisbon and other European cities have struggled with the same collision between successful urban economies, insufficient housing, environmental constraints and neighborhood resistance. What makes Berlin different is the scale of the renter population and the political memory of a city that was once famous for comparatively cheap space. Tempelhofer Feld has therefore become more than a planning dispute. It is a referendum by proxy on whether the Berlin of abundant, accessible space can survive the Berlin of high demand and metropolitan prosperity.
The rent numbers tell two different stories
One reason the housing debate is so heated is that Berlin’s rental data can appear contradictory until the categories are separated. The official 2026 rent index reports a median of €7.71 per square metre across the regulated reference stock used to assess typical existing rents. By contrast, market reports tracking newly advertised homes show asking rents at roughly twice that level. Both can be accurate at the same time. Long-standing tenants benefit from Germany’s rent-protection framework and older contracts, while newcomers face the price of scarce vacancies in a competitive market.
That gap creates a “lock-in” effect. Households with relatively affordable contracts may avoid moving even when their apartment is too large, too small or badly located for their current needs, because a new lease could cost dramatically more. This reduces turnover and makes available housing even scarcer. Investitionsbank Berlin explicitly warns that the spread between existing and asking rents can inhibit mobility and make it harder for households to adapt. It is a reminder that housing markets are not simply about the number of units but about how easily people can move between them.
For the Left and tenant groups, the answer is stronger protection against excessive rents, more public and cooperative housing, tighter controls on short-term and furnished rentals, and an expanded role for the state. For the CDU and market-oriented economists, the durable answer must include substantially more construction because regulation can redistribute scarcity without eliminating it. The SPD and Greens sit between those poles, combining varying degrees of tenant protection with public investment and supply measures. In practice, any future coalition is likely to produce a hybrid because Berlin’s fiscal, legal and political constraints make a single-track strategy difficult.
The economics of construction complicate every promise. Even if planning approvals accelerate, high land prices, wages, materials, financing costs and energy standards can make newly built homes expensive. Public housing lowers rents only by shifting part of the cost to the state, state-owned companies or cross-subsidy. Private development requires returns high enough to attract capital. That leaves Berlin with an uncomfortable arithmetic: the city needs more homes quickly, but the homes most financially viable to build are often too expensive for the households under the most pressure.
A successful city confronts the cost of success
Berlin’s housing crisis has developed alongside an economy that has often outperformed the rest of Germany. Reuters noted that services generate almost 90% of the city’s economic output and that more than 600 companies were founded in Berlin in 2025. The capital has become a European center for startups, digital services, design, media, tourism and research. That growth has attracted workers, students and investors, helping transform a city once known for low rents and abundant vacant space into one of Europe’s most sought-after urban markets.
The political difficulty is that growth creates both winners and losers. Existing owners benefit from higher asset values. Landlords may benefit from scarcity, while established tenants with protected leases can retain relatively low housing costs. New arrivals, younger renters, separated families, refugees and workers moving for jobs face the most punishing part of the market. Cultural venues and small businesses also compete for space in neighborhoods where commercial rents rise alongside housing values. Berlin’s celebrated cultural ecosystem depends on precisely the kind of low-cost space that successful cities tend to eliminate.
That is why the election is not simply about rent. It is about whether Berlin can remain socially mixed while continuing to grow. A city may generate more jobs and tax revenue while becoming less accessible to the people who provide its essential services. It may attract investment while hollowing out the communities that made it attractive. Those tensions explain why housing has overtaken even national questions in the campaign: voters experience foreign policy through news, but they experience housing every month when rent is due or every time they search for an apartment.
Coalition arithmetic could matter more than first place
Even if the Left finishes first, that would not guarantee it the mayoralty. Berlin’s governing mayor is elected by the House of Representatives after parties negotiate a coalition. The latest polls point toward several arithmetically possible combinations among the Left, CDU, Greens and SPD, while the AfD’s isolation sharply narrows the politically plausible options. The BSW’s fate around the five-percent threshold could also shift seat allocations enough to change which three-party combinations command a majority.
A Left-Green-SPD coalition would be ideologically coherent on several social and environmental issues, but it would need to reconcile different approaches to housing supply, public spending and administration. A CDU-Green-SPD alliance would preserve a centrist governing core but could be attacked from both left and right as an establishment arrangement built mainly to exclude stronger opposition parties. A coalition involving both the CDU and Left would be arithmetically imaginable under some results but politically extraordinary given their deep ideological differences and the CDU’s historical opposition to cooperation with the Left.
The final map will also depend on constituency results and the distribution of list seats, not just headline vote shares. Small changes around the threshold can produce disproportionate effects on coalition mathematics. If the BSW remains below 5%, most of its votes would not translate into parliamentary seats, increasing the effective share of seats won by parties that cross the barrier. If it enters, the chamber becomes more fragmented and coalition negotiations become harder. That is one reason election-night seat projections will matter at least as much as the race for first place.
For voters, the distinction between winning the election and governing after it may feel frustrating, but it is inherent in Germany’s coalition-based parliamentary system. Parties campaign on individual programs, then compromise after the result. The question on Monday may therefore be less “who won Berlin?” than “which parties can govern together without abandoning the promises that got them there?” Housing will make that negotiation especially difficult because the campaign’s sharpest differences concern policies that cannot easily be split down the middle.
Merz watches Berlin after the Saxony-Anhalt shock
The federal implications are impossible to separate from Chancellor Merz’s current weakness. Earlier this month the AfD won nearly 44% in Saxony-Anhalt, a historic result that shook the CDU and intensified questions about Merz’s leadership. Reuters reported on September 14 that an INSA poll found 78% of respondents did not want Merz to remain chancellor, including a majority of conservative voters. Such national polling can move quickly, and it should not be read as a direct forecast of Berlin. But it illustrates the pressure under which the chancellor enters another election weekend.
Merz has responded by insisting that Germany’s strategic choices, particularly support for Ukraine and European security, should not be subordinated to short-term political pressure. The AfD argues for restoring relations with Moscow and ending German support for Kyiv, while Merz has said he will not retreat from the current policy. Berlin’s campaign has largely focused elsewhere, but a weak CDU result would give his internal critics another data point for their argument that the party’s national strategy is failing to connect with voters worried about living costs and public services.
A stronger-than-expected CDU result would tell a different story. It would suggest that local leadership and urban issues can partially insulate the party from national dissatisfaction. It could also weaken the claim that the AfD’s surge is inevitably swallowing the conservative electorate. Berlin is an imperfect national bellwether, but precisely because it is demographically and politically different from Saxony-Anhalt, its result can show whether the CDU’s problems are broad-based or concentrated in particular regions and voter groups.
Sunday is even more consequential because Mecklenburg-Western Pomerania is also voting. The two state elections will be read together as a national mood test even though their electorates and issues differ sharply. A poor CDU performance in both would deepen the sense of crisis around Merz. A split result would underline the regional fragmentation of German politics. Either way, the chancellor will face a difficult task on Monday: explain what local voters said without pretending that state elections have no national meaning.
Administrative credibility is part of the contest
Berlin’s election administration carries unusual political sensitivity because the city is still marked by the failures of the 2021 vote, which had to be repeated in 2023 after severe organizational problems. Sunday’s election returns Berlin to its normal timetable. Officials have spent years trying to rebuild confidence in the mechanics of voting, from staffing and ballot distribution to polling-station capacity. The state election authority says election notifications were sent between August 10 and 30, and detailed instructions have been published for postal voting, accessibility and polling-place procedures.
The practical test is straightforward but important: can the capital run an ordinary election without the logistical failures that once became a national embarrassment? Around 2.4 million notifications for the parliamentary election and thousands of polling locations create a complex operation. Authorities have also emphasized accessible voting and published information in simplified language. For voters, those measures may seem routine. In Berlin, routine is the goal.
Trust in administration also intersects with the campaign’s substantive themes. Housing permits, school places, immigration offices, public transport, energy infrastructure and neighborhood services all depend on state capacity. Parties can promise ambitious interventions, but Berlin’s recent history has made voters skeptical about delivery. One of the quiet questions beneath Sunday’s ideological arguments is therefore whether the next coalition can make the city’s institutions work faster and more reliably, regardless of which housing model it chooses.
What Sunday’s result can — and cannot — prove
The temptation after any high-profile state election is to treat it as a verdict on the entire country. Berlin will not provide that. Its renter-heavy population, large service economy, unusually high share of younger and international residents, and distinctive political history make it different from Germany as a whole. Local scandals and the housing crisis have shaped this contest in ways that may not travel far beyond the city’s boundaries. A Left victory in Berlin would not mean Germany is moving sharply left, just as a strong AfD result would not mean Berlin has become an AfD city.
What the result can show is how voters respond when economic scarcity becomes the dominant political issue. It can show whether the Left can convert tenant anxiety into durable governing strength, whether the CDU can persuade voters that construction and administrative reform are more credible than stronger controls, whether the SPD can survive as a central coalition party despite falling support, and whether the AfD can expand further in a city very different from its strongest eastern bases. Those are meaningful signals even if none is a national referendum.
The election can also reveal how far Germany’s coalition system is being stretched by fragmentation. If five parties enter the chamber with none near 30%, building a government may require compromises that voters did not hear during the campaign. The more fragmented the parliament becomes, the more post-election negotiation matters. That dynamic is increasingly common across Europe, where established center-left and center-right parties face competition from both flanks and from newer movements.
After 6 p.m., the housing argument enters coalition talks
When polls close at 6 p.m., initial exit polls will offer the first serious indication of whether the Left has held its narrow lead, whether the CDU has recovered, how high the AfD has climbed and whether the BSW has crossed the threshold. The first numbers will be provisional. Official counting will continue through the evening, and the state election commission will certify the final result later. Coalition talks are expected to take weeks rather than hours.
Those negotiations will quickly return to the issues voters have spent the campaign debating. Any viable government will need a housing program that combines some answer on construction, tenant protection, land use and public investment. Tempelhofer Feld could become a coalition red line. So could rent controls, the role of state-owned housing companies and the scale of public spending. Parties that campaigned on sharply different solutions may discover that forming a majority requires them to dilute the policies that most clearly distinguished them.
For Berlin, that may be the central political test after election day. The city does not lack diagnoses of its housing crisis. It lacks enough affordable homes, enough available land at acceptable prices, enough fast approvals and enough consensus about how to distribute the costs of solving the problem. Sunday’s vote will decide who gets the authority to try. It will not make the underlying trade-offs disappear.
For Germany, the result will arrive at a moment when voters are already questioning the capacity of established parties to manage economic insecurity, migration, infrastructure and war-related pressures at the same time. Berlin’s answer may be highly local, but the political warning will travel. In the capital of Europe’s largest economy, the most powerful campaign issue is not an abstract argument about ideology. It is the price, availability and future of a place to live.
