That is older than the Butte County median of 1981.1 Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. Owner-occupied homes in Thermalito are older than rentals: a median build year of 1967 against 1972.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.

Housing in Thermalito is mostly detached single-family: 72% of units, with 4% in buildings of five or more units.
