NAHB just released a sharp new analysis of the 2023 American Housing Survey, and it confirms what many builders already sense on the jobsite: certain physical features dramatically influence a home’s market value. And some matter far more than others.
The biggest driver? Square footage. Compared with homes under 1,000 sq. ft., values jump:
- +17% for 1,000–2,000 sq. ft.
- +30% for 2,000–3,000 sq. ft.
- +55% for homes over 3,000 sq. ft.
But the real surprise is the power of bathrooms.
NAHB reports that:
- Each full bathroom adds roughly 32% to value
- A half bath adds around 15%
- An extra bedroom, by comparison, brings only about 5% (when square footage stays constant)
Newer homes also earn premiums:
- Homes built 2010–2019: +13%
- Homes built 2020 and after: +19%
And the right amenities still matter. Garages (+10%), fireplaces (+10%), and centralized AC (+7% nationwide, up to +48% in the South) continue to deliver strong returns.
For builders, the takeaway is simple: not all upgrades carry the same weight. Wise feature choices can meaningfully increase value, buyer appeal, and profitability.
