Send me the detailed estimateIn Westridge, Alpine Hills and Central Portola Valley the bathroom is usually the original 1950s or 1960s one: a small hall bath and a modest primary bath in a house that steps down a slope. The downhill side often has a crawlspace that makes moving a drain straightforward, while the uphill end can sit close to grade, so where the bathroom falls in the house decides how much plumbing can move. Portola Valley Ranch bathrooms are compact rooms in clustered 1970s houses; the remodel is interior work on a town building permit, and the Ranch Design Committee only comes in if a window, skylight or vent on the outside changes. In Los Trancos Woods the houses grew out of 1920s summer cabins on septic systems sized for seasonal use, so adding a bathroom there is a county Environmental Health question before it is a design question.

The San Andreas fault runs through Portola Valley, and the town has mapped its ground since Resolution 500-1974, with a geologic map and a ground movement potential map that set building setbacks along the active traces. For a kitchen or bathroom inside the existing house, that rarely changes the job: the Town Geologist steps in for site development permits, foundation repair over 35 lineal feet, sites inside the fault setback or a flood zone, and additions over 500 square feet. It matters when a bathroom remodel turns into a bump-out, or when we open an old floor and find a cracked foundation, so we check the town’s maps for your parcel before we price anything structural.
Town of Portola Valley Planning & Building Department (765 Portola Rd, Portola Valley) issues permits in Portola Valley. Typical review time: not published by the town; we ask the Building Division for the current queue when we apply. We prepare the drawings, pull the permit under our license and meet the inspector at every visit; the fee is a line item on your estimate.
WestLight Energy (formerly Peninsula Clean Energy) supplies the power and PG&E delivers it. WestLight's rebates cover heat pump water heaters and heating, with a bonus for a panel upgrade done alongside them.
Inside town limits, the Town of Portola Valley Building Division at Town Hall, 765 Portola Road. In Ladera, Los Trancos Woods or Vista Verde it is San Mateo County Planning & Building; we check your parcel first and pull the right one.
Rarely for interior work. The Town Geologist reviews foundation work over 35 lineal feet, sites inside the fault setback or a flood zone, and additions over 500 square feet, so a bathroom in the existing footprint usually skips it.
Not for interior-only changes. The Westridge Architectural Supervising Committee reviews things like skylights, prominent windows, roofing and exterior colors, and its approval is separate from the town’s.
California requires homes built before 1994 to have water-conserving toilets, showerheads and faucets when they are remodeled under permit. Every Willow bathroom already includes WaterSense fixtures, so it costs you nothing extra.
