Apartment starts retreat as permits edge higher
Apartment construction remains under pressure: September multifamily starts fell 25.9% from a year earlier, even as permits edged higher. The gap points to a pipeline where projects may be approved but financing and construction economics still determine which ones proceed. A permit shows that a project has cleared an early step; it doesn’t show that a developer has secured the capital, priced the work, or decided that expected rents justify beginning construction.
HUD and the U.S. Census Bureau reported a seasonally adjusted annual rate of 349,000 starts in buildings with five or more units, down 7.2% from August. Across all privately owned housing, starts reached 1.2 million, a 5.2% monthly decline and a 7.4% drop year over year. Single-family starts totaled 859,000, down 4.6% from August but 2.6% above September 2025.
These figures describe different slices of the housing market, so the overall starts total shouldn’t be read as a direct measure of apartment activity. The multifamily reading is more relevant to developers and property owners tracking new rental supply. Its sharp annual decline suggests that fewer apartment projects are making the transition from planning to active construction, even while the broader housing picture includes a modest annual gain in single-family starts.
Permits rise while completions remain lower
September multifamily permits came in at a seasonally adjusted annual rate of 503,000, up 5.9% month over month and 1% year over year. Completions reached 339,000, rising 14.9% from August but falling 20.4% compared with a year earlier. Permits and completions sit at different points in the building process: permits reflect authorized plans, while completions capture projects that have finished construction.
Those permits don’t guarantee starts. Greg Willett, chief economist at Leaselock, said developers have projects ready to begin but are weighing whether capital is available. Improving rent growth could support more construction starts, he said, while interest rates remain a counterweight. “So, are these projects going to go or not? I'm not sure,” Willett said.
That uncertainty makes the permit figure a limited signal of near-term building activity. Developers may have plans in hand, but the decision to break ground still depends on financing and expected operating performance. A project that looks workable on paper can become harder to justify if borrowing costs, construction bids, or rent assumptions shift before work begins.
This is more significant than it looks: a permit increase can make the pipeline appear healthier even as starts contract. The two measures aren’t contradictory; they show that authorization and execution are moving at different speeds. For anyone reading the data as a sign of future supply, the distinction matters. Planned units don’t house tenants until projects are built and completed.
The South leads regional starts
The South was the only region where total housing starts increased year over year, rising 11% in September. Single-family starts there climbed 8.8% from a year earlier. That regional strength offers a counterpoint to the national decline, but it doesn’t establish that apartment building is rising across the South: the total starts figure combines housing types.
Starts fell across the other regions: 30.9% in the Northeast, 25.4% in the West and 19.4% in the Midwest. In each, single-family construction held up better than the combined total, which also includes apartments. That difference suggests multifamily weakness is weighing on the broader regional readings, though the figures provided don’t isolate the apartment contribution in each region.
Regional comparisons also need care. A national total can conceal very different local conditions, and one region’s gains don’t tell developers whether a particular project will attract tenants or secure financing. If you’re working in this space, the useful question is whether local demand and project costs support construction—not whether the regional headline is positive.
Materials costs add pressure to project budgets
Construction input prices rose 2.2% month over month in September and 11.2% year over year, according to an Associated Builders and Contractors analysis of federal Producer Price Index data. The annual increase was the largest in almost four years. For a project still being priced or evaluated, rising inputs can narrow the room between expected revenue and the cost of delivery.
ABC attributed much of the latest rise to higher fuel costs linked to the Iran war and tariffs on key building materials. Petroleum products recorded the steepest increases, while metals also became more expensive. The cost environment reaches beyond budgets: longer lead times for key steel components are making it harder for contractors to keep work on schedule, Associated General Contractors of America Chief Economist Ken Simonson said.
Cost and timing can reinforce each other. When materials become more expensive, developers may need to revisit project budgets; when key components take longer to arrive, schedules can become harder to maintain. That can complicate a start decision, especially when financing costs remain a concern and the expected performance of a project depends on rents that may improve only gradually.
And this is the part most people overlook: a project doesn’t need to be formally canceled to stop contributing to near-term supply. It can remain permitted while its sponsor waits for costs, financing, or expected rents to make the numbers more workable. A delay still changes when new units are likely to reach the market.
What the figures mean for the pipeline
For multifamily developers, September’s figures show a market with permits available but starts retreating sharply. Whether better rent growth can bring planned projects into construction will depend in part on financing costs and the price and availability of materials. The permit uptick offers some evidence of continued project preparation, but the decline in starts is a clearer sign that many plans haven’t yet become active building work.
The next question is whether the gap persists. One month’s data can’t establish a lasting direction, and the figures don’t identify which permitted projects will proceed. Still, the combination of weaker starts, lower annual completions, and rising input prices gives developers reasons to scrutinize budgets and timing before committing capital. More construction may follow if rent growth improves enough to support project economics; interest rates and material costs remain constraints.
For renters and property owners, the distinction between proposed supply and completed buildings matters. Permits are a forward-looking clue, while starts show that construction has begun and completions show that units have finished the process. The present signal is mixed. Planned activity exists, but the path from authorization to delivered apartments remains uncertain. Not a pipeline that can be counted on yet.
