Berkeley Climate

Berkeley's climate transitions from the foggy flatlands near the Bay to the warmer, drier hillside neighborhoods above the UC campus. The flats receive more marine fog, supporting subterranean termite activity in moist soils. The hills and hillside neighborhoods are warmer and drier — ideal drywood termite territory, with swarms active roughly August through October. Annual rainfall averages 22–25 inches in the hills.

Housing Stock

Berkeley reads as one old city but inspects as three. The pre-1923 brown shingle and Craftsman stock south of campus is the classic case: old-growth Douglas fir and redwood framing, shingle siding laid over sheathing with gaps behind it, and in many houses no record of a comprehensive termite treatment in living memory. The 1923 fire rebuild north of campus produced a distinct mid-1920s layer, stucco over wood frame, where the exterior gives away far less at a glance and the framing has to be reached through the attic and the crawl space. Everything west toward the Bay and south past Ashby is a mix of pre-war cottages and post-war infill. Across all three, the recurring complication is subdivision. Single-family houses turned into duplexes, triplexes, and rented flats decades ago, and the shared attics, common walls, and stacked plumbing chases that came with those conversions are the routes colonies and rodents use between units.
