Census and NOAA figures for the city of Walnut Creek in Contra Costa County, not the metro, with a source for each.
The median home in the city of Walnut Creek was built in 1974, older than the U.S. median of 1980 and about the same as the California median of 1976.1 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. The stock is old by national standards: 66% of Walnut Creek's housing units were built before 1980 (U.S. 50%), and only 6% since 2010.1 Owner-occupied homes in Walnut Creek are older than rentals: a median build year of 1972 against 1979.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
Most housing units in Walnut Creek are not detached houses: 37% are in buildings of five or more units and only 37% are detached single-family homes.1 With most units in multi-family buildings, condo and HOA approvals sit alongside the permit for interior work. 64% of occupied homes in Walnut Creek are owner-occupied (56% statewide).1 The median owner-occupied home in Walnut Creek is valued at $1,057,300 (ACS), above the California median of $734,700.1 Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
Freezing nights are rare: the nearest NOAA station (Concord Buchanan Fld) averages 8.5 nights a year at or below 32°F.2,3 With few freezing nights, water and sun rather than ice are what exterior details are built against. Summers run hot, with about 51 days a year at 90°F or more and 9 at 100°F.2,3 A long hot season shortens the life of roofing, sealants and garage-door electronics, and it shapes what a contractor specifies.
Annual precipitation is low, about 16 inches.2,3 Low rainfall shifts the wear to UV and heat, which age finishes and sealants. Heating and cooling loads are both real: about 2,154 heating and 1,078 cooling degree days a year (base 65°F).2,3 Walnut Creek is about 25 miles from the ocean or Gulf coast in a straight line.4,5 Proximity to salt air makes fastener grade and corrosion protection part of every exterior quote.
Walnut Creek sits in IECC climate zone 3B (Hot-Dry).6 Building permits in Walnut Creek are normally issued by the city building department.7,8
