Census and NOAA figures for the city of Clayton in Contra Costa County, not the metro, with a source for each.
The median home in the city of Clayton was built in 1983, newer than the U.S. median of 1980 and newer than the California median of 1976. That is newer than the Contra Costa County median of 1978.1 Clayton's housing is newer than the national mix: 45% of units predate 1980 against 50% nationally, and 1% date from 2010 or later. The largest single share, 48%, dates from 1980-1999. That makes it an older stock than Contra Costa County as a whole (53% built before 1980).1 On houses from the 1980s and 1990s, polybutylene supply lines, builder-grade windows and first-generation openers are the usual items a contractor confirms before quoting. Owner-occupied and rented homes in Clayton are of similar age: median build years 1983 and 1986.1
Housing in Clayton is mostly detached single-family: 86% of units, with 1% in buildings of five or more units.1 A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. Home ownership is the norm in Clayton: 89% of occupied homes are owner-occupied, above the California share of 56%.1 The median owner-occupied home in Clayton is valued at $1,055,200 (ACS), above the California median of $734,700. Within Contra Costa County the median is $866,800, so Clayton sits above it.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 Clayton is about 31 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.
Clayton sits in IECC climate zone 3B (Hot-Dry).6 Building permits in Clayton are normally issued by the city building department.7,8
