Pulse Analysis

The 2025 housing data reveal a nuanced picture for builders. While single‑family detached construction continues its downward trajectory, townhouse starts held steady at 173,000 units, essentially mirroring the previous year. The fourth quarter’s 38,000 attached starts marked the sector’s weakest performance since 2023, underscoring the fragility of traditional single‑family demand. Yet townhouses maintained a solid foothold, representing more than 17% of all single‑family starts in the final quarter, a share that has steadily risen amid tightening land availability and evolving consumer preferences.

A deeper dive into market‑share metrics shows townhouses capturing 18.4% of new single‑family starts on a one‑year moving average in Q3, the highest figure in the dataset dating back to 1985. This milestone eclipses the previous historic high of 14.6% set in early 2008, highlighting a long‑term structural shift. Builders are responding by allocating more resources to attached units, recognizing that zoning flexibility and lower per‑unit land costs make townhouses an attractive proposition in many suburban and urban fringe markets.

Looking ahead, demographic trends favor medium‑density living environments. Millennials and Gen Z homebuyers prioritize walkable urban villages, access to amenities, and shorter commutes, all of which align with townhouse formats. Municipalities that relax zoning restrictions stand to benefit from increased tax bases and diversified housing stock. Consequently, investors and developers are likely to increase exposure to townhouse projects, viewing them as a resilient segment that can thrive even as traditional single‑family construction faces headwinds.
