Three-bedroom single-family homes remained the most common home built with respect to the number of bedrooms. The share of starts for four-bedroom homes declined for the fourth consecutive year but remained well above the shares for two-bedroom or less and five-bedroom or more homes.

Despite three-bedroom homes remaining the most common for new single-family starts, their share edged down to 46.5% from 47.0% in 2024. Four-bedroom homes also declined, falling to 31.7% from 32.4%, the lowest level since 2010. Meanwhile, homes with two bedrooms or less increased to 11.5% from 11.4%, while those with five bedrooms or more rose to 10.3% from 9.2%.

U.S. Divisions

Across U.S. Census Divisions, the share of new single-family homes with four or more bedrooms displays geographic variation. The share ranged from a low of 28.1% in the New England and East North Central division to the highest share of 49.3% in the West South Central division.

Purpose of Construction

The number of bedrooms in new homes also varies depending on the purpose of construction (built-for-sale, contractor-built, owner-built, built-for-rent). Most of this variation comes from the two-bedroom or less homes and four-bedrooms homes. For example, the share of new single-family homes with two bedrooms or less ranges from 6.2% of homes built-for-sale to 32.5% of homes owner-built. Meanwhile, three-bedroom homes and five or more-bedroom homes display relatively little change across purpose of construction. Five or more-bedrooms homes held the smallest share of starts across purpose of construction for all types except for built-for-sale homes.
