Census and NOAA figures for the city of Cornelius in Washington County, not the metro, with a source for each.
The median home in the city of Cornelius was built in 1992, newer than the U.S. median of 1980 and newer than the Oregon median of 1981. That is in line with the Washington County median of 1990.1 Most of Cornelius's housing is recent: only 32% of units predate 1980 (U.S. 50%) and 18% were built since 2010. The largest single share, 38%, dates from 1980-1999. That makes it much the same age as Washington County as a whole (36% built before 1980).1 A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Owner-occupied homes in Cornelius are newer than rentals: a median build year of 1994 against 1980.1 With owner-occupied homes skewing newer, many requests are first-time replacements of original builder-grade components.
Housing in Cornelius is mostly detached single-family: 67% of units, with 6% in buildings of five or more units. Mobile and manufactured homes are 11% of units.1 A mostly detached stock means the full range of exterior work applies: roofs, garage doors, chimneys and backyard units. 74% of occupied homes in Cornelius are owner-occupied, above the Oregon share of 63%.1 The median owner-occupied home in Cornelius is valued at $452,900 (ACS), close to the Oregon median of $477,600. Within Washington County the median is $588,000, so Cornelius sits below it.1
The Portland-Hillsboro Ap station averages 64 nights a year at or below 32°F and 3 at or below 20°F.2,3 A real freeze season means masonry, roofing and exterior sealing are specified for freeze-thaw cycles. Summer heat is moderate: about 17 days a year reach 90°F.2,3 Annual precipitation is about 36 inches, with 4 days a year bringing an inch or more.2,3
Heating dominates the year: about 4,830 heating degree days against 275 cooling degree days (base 65°F).2,3 In a heating-led climate, insulation and air sealing carry most of the energy-code weight for any work that opens the envelope. The coast is about 44 miles away, so storm systems arrive without salt air.4,5 Cornelius sits in IECC climate zone 4C (Marine).6
Building permits in Cornelius are normally issued by the city building department.7,8
