Census and NOAA figures for the city of Downey in Los Angeles County, not the metro, with a source for each.
The median home in the city of Downey was built in 1959, older than the U.S. median of 1980 and older than 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: 83% of Downey's housing units were built before 1980 (U.S. 50%), and only 2% since 2010.1 Owner-occupied homes in Downey are older than rentals: a median build year of 1956 against 1967.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
Downey has a mixed housing stock: 56% detached houses, 6% attached or townhouse units and 31% in buildings of five or more units.1 Owners and renters are roughly balanced in Downey, with 51% of occupied homes owner-occupied (56% statewide).1 The median owner-occupied home in Downey is valued at $796,600 (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.

Summers bring about 26 days a year at or above 90°F.2,3 Annual precipitation is low, about 14 inches.2,3 Low rainfall shifts the wear to UV and heat, which age finishes and sealants.
Cooling dominates the year: about 1,296 cooling degree days against 1,005 heating degree days (base 65°F).2,3 In a cooling-led climate, attic ventilation, duct sealing and window solar gain are where the energy code concentrates.
