San Antonio — modular, container,
and tiny homes in Texas.

San Antonio is one of the most permissive large-metro ADU markets in the country. The city permits detached accessory dwellings on most residential lots and modular product clears both the state IRC insignia and local zoning fast.

What the market looks like

San Antonio in 2026.

San Antonio's Unified Development Code permits detached ADUs (called 'accessory apartments' locally) on most single-family lots with off-street parking. Texas has no state ADU law preempting local rules, so San Antonio operates on its own local ordinance — one of the more permissive in the state. Bexar County and Comal County both accept state modular insignia product with routine review. Summer heat load matches Phoenix — SEER-16+ HVAC, high-albedo roofing, and R-30 wall assemblies are standard. HUD Small-Area FMR covers all Bexar County ZIPs. Modular and container product both ship regularly to the metro via Backcountry Containers and Custom Container Living — Texas has one of the deepest container-home ecosystems in the country.
