Homes in Orinda
Orinda is known for hillside homes on wooded lots, many from the 1940s through the 1960s, plus later custom homes. Steep sites mean equipment often sits in under-floor spaces, basements, or garages, and outdoor unit placement takes planning. Many older homes have heating only.
Climate and what it means for your system
Orinda sits just east of the Berkeley Hills, so it is noticeably warmer and sunnier than Oakland or Berkeley in summer, but cooler than the valleys farther east. Winter nights are cold, and some canyon neighborhoods stay shaded and cool through the day.
Most of Orinda falls in California Title 24 climate zone 12. The exact zone is set by ZIP code, and we confirm it for your address when we design a system.
Utilities
PG&E supplies natural gas and delivers electricity. Check your bill to see whether your electricity generation comes from PG&E or a community choice program. Rates differ, and that affects the operating cost of a heat pump compared with a gas furnace.
Permits
Orinda addresses appear in Contra Costa County's building inspection schedules, indicating permits and inspections run through the county's Building Inspection Division. We confirm the correct office when pulling your permit.
