Germany is approving more homes — but building fewer

Building permits in Germany rose 10.8% to 238,500 in 2025, the first annual increase since 2021 and a meaningful recovery from 2024's decade low. January 2026 continued the trend with an 8.4% year-on-year gain. Federal Construction Minister Verena Hubertz called it evidence that "the turnaround in housing construction has begun." The industry's response was considerably more measured. As IVD president Dirk Wohltorf put it: "You cannot live in building permits."

The gap between what Germany approves and what it actually builds has rarely been wider. Completions are heading downward even as permits rise. The industry estimates around 200,000 homes will be completed in 2026, down from 251,900 in 2024 and a full third below the 306,000 delivered as recently as 2020. Against estimated annual demand of at least 300,000 to 320,000 units, the structural shortfall is deepening. Industry lobby ZIA calculates that average annual demand between 2021 and 2025 stood at 372,600 units. Against that, 2024's permit total of 215,300 represented a shortfall exceeding 40%. Rising approvals are a necessary condition for recovery. They are not, on their own, sufficient.

Germany is planning more homes. It is delivering fewer.

Berlin illustrates the dynamic clearly. Investitionsbank Berlin (IBB) estimates approximately 16,300 completions in the capital last year, around 1,000 more than the previous year. However, this was driven largely by the clearing of a 50,000-unit construction backlog of previously approved projects rather than new activity. According to Andreas Tied of IBB, the backlog is compensating for weak approval figures from earlier years. Once it clears, the pipeline thins.

The fundamental problem is cost. At €4,630 per square metre in major cities, rising to €5,400 when land is included, new-build residential construction requires a minimum basic rent of €18 per square metre simply to be financeable, according to Dietmar Walberg of the ARGE construction research institute in Kiel. That is well above what average earners can pay. In Berlin, IBB data shows the average household can afford basic rents of between €12 and €12.90 per square metre. Asking rents for new-build stock average €20, with many projects priced at €25 or above. The arithmetic does not work for a significant share of the population, and developers know it.

Construction costs have risen around 60% between 2015 and the end of 2023. Projects approved under earlier assumptions are now being reassessed, delayed or abandoned. As financing conditions tightened in 2022, demand from owner-occupiers dropped sharply, forcing developers to revisit both pricing and product. At the same time, many schemes initiated in the previous cycle no longer meet current requirements for affordability or floor-plan efficiency. Financing gaps, land transfer tax, equity requirements and regulatory complexity are compounding the problem at every stage from approval to completion. "Looking at approval figures is of little help if projects subsequently fail due to financing gaps, excessive standards, massive regulations and the tax burden," says Wohltorf.

The war in Iran has added a fresh layer of uncertainty. Rising energy and material prices threaten to push construction costs higher still, while elevated inflation expectations are feeding into construction interest rates. Tim-Oliver Müller, CEO of the German Construction Industry Association, warned at the Housing Construction Day in Berlin that residential construction orders had already fallen 15% in real terms in January, calling it "a warning that the upturn is not yet self-sustaining."

The industry's diagnosis is blunt: Germany is not failing to approve housing, it is failing to build it cheaply enough. The proposed solution is to move away from an implicit gold standard and revert to legal minimums. The so-called Building Type E concept, including thinner floor slabs, fewer sockets, no mandatory underground car parks and reduced sound insulation requirements, could cut construction costs from around €4,650 to approximately €3,500 per square metre, according to Robert Feiger of the IG Bau construction union. Schleswig-Holstein has already delivered social housing below €3,500 per square metre under reduced standards, while Bavaria currently has 19 pilot projects underway.

Costs, not permits, remain the real constraint

The federal government is working on legislation. Hubertz and Justice Minister Stefanie Hubig have committed to a Building Type E Act this year, though no cabinet decision has yet been reached and no specific timeline given. CDU construction expert Jan-Marco Luczak has called it a potential "game-changer." Critics warn that noise protection, accessibility and consumer quality standards must not be sacrificed in the process, while the Builders' Protection Association supports the principle but flags implementation risks.

ZIA chief executive Aygül Özkan has been clear that legislation alone will not be enough. Three structural levers are required in parallel: a new basic housing standard to reduce costs, reform of land transfer tax, including its waiver for first-home buyers, and equity-replacing measures such as state guarantees, potentially through the planned Germany Fund. "Only when we decisively apply these structural levers will rising approval figures actually result in new housing," says Özkan.

Most construction firms do not expect the government's "construction turbo" to deliver a noticeable impact before 2027 or 2028. For investors and developers, the near-term picture therefore remains one of constrained supply, higher costs and a financing environment that has tightened further since the start of the year. Permits are rising, sentiment has genuinely improved, and the second half of 2025's 17.8% year-on-year surge in approvals is an encouraging signal. But the homes Germany needs are not yet being built at anything close to the required rate. Until the cost structure changes, the gap between what is approved and what is delivered will remain the sector's defining problem.
