Housing market splinters: single-family up, apartments stall
The gist
The housing market is splitting in two, with single-family home construction rising while new apartment builds stall out.
What to know
- Single-family housing starts jumped 7.6% in August, but apartment (multifamily) starts dropped 15.5% year over year and permits also fell.
- Builders are flocking to single-family projects as rising construction costs and 6.76% mortgage rates make apartment deals tough to finance.
- Overall housing supply remains tight, with the apartment pipeline thinning even as detached-home building rebounds.
A Tale of Two Markets
August’s data reveals a housing sector split, with single-family construction surging even as falling permits and multifamily declines signal a shrinking overall pipeline.
September’s housing update crystallized the split inside residential construction: single-family activity improved in August even as the broader pipeline weakened. Reuters summed up the turn in its Sept. 17 headline — “US single-family housing starts rebound in August; building permits fall” — capturing a market where one segment is recovering at the same moment future supply signals are softening.
That divergence is the key dated development in the late-summer data. August single-family starts rose 7.6%, but the offset from apartments and other multifamily projects ran the other way, with multifamily starts down 15.5% from a year earlier and permits also retreating, showing that the rebound in detached-home building was not broad enough to describe the construction market as uniformly strengthening.
Read together, the August figures show not a simple housing recovery but a bifurcated construction cycle. Single-family builders added momentum, yet falling permits and a steep multifamily drop signaled that the next wave of projects was thinning, making the September 2026 release important less for a headline increase in starts than for revealing how unevenly new supply was being generated across the market.
Financing Crunch Hits Apartments
Rising rates and tighter lending are stalling apartment projects first, causing multifamily starts to plunge while single-family building holds steadier under less financial strain.
The financing squeeze is hitting apartment construction first because multifamily deals are more exposed to borrowing costs. As Maor Greenberg put it, “Rates hit multifamily projects first because apartment projects run on construction loans and pro formas that only work at certain rates,” and “when financing gets expensive and uncertain, that math breaks down”; by contrast, “A single-family home does not carry the same financing load,” helping explain why multifamily starts once “collapsed 41.6 percent in a single month, falling from 486,000 to 284,000 units,” while single-family activity proved steadier.
That pressure intensified as mortgage rates hovered around 6.7%, with the average 30-year fixed rate at 6.76% last week, up from 6.71% the week before, while builders still pointed to a “sub 6% mortgage market.” Higher rates are also colliding with rising input costs, tightening margins and thinning the future pipeline most visibly in apartments: September’s market read showed that “Apartments dragged totals: Starts on buildings with 5 or more units plunged 22.5% to 344,000,” and that “single-family housing starts jumped 7.6% in August, but overall construction fell 2.6% as apartment work and permits dropped…,” leaving overall housing supply constrained.
