Bathrooms in Lafayette's 1950s and '60s Homes
Nearly 70% of Lafayette’s single-family homes were built in the postwar boom, many in the 1950s and 1960s, in neighborhoods like Burton Valley, Silver Springs and Happy Valley. Their original bathrooms tend to be compact, with tub-shower combinations, small windows and plumbing that is ready to be replaced. We rebuild them with walk-in showers, double vanities, better ventilation and lighting, and layouts that work for aging in place.

What Lafayette Requires for a Bathroom Remodel
Interior bathroom remodels do not change the outside of the house, so they do not trigger Lafayette design review. If plumbing, wiring or walls change, the project still goes through the City’s zoning check and the County building permit.
- Zoning plan check with the City through idtPlans: site plan, floor plans and elevations.
- Central San review if the work affects sewer.
- Contra Costa County Fire Protection District review if applicable.
- County building plan check after the City stamps the drawings.
- County inspections and final.
- GFCI-protected bathroom circuits and a code-compliant exhaust fan.
- Safety glazing near tubs and showers.
- Water-conserving fixtures, which California requires on permitted work in older homes.
- Updated smoke and CO alarms.
- Lead-safe work practices for homes built before 1978.
