Homes we remodel in Woodside

Most Woodside tub-to-shower conversions are in the hall bath of a Glens cabin-site house or a mid-century ranch, where a 60-inch tub fills the alcove. In the older Glens houses the tub is often cast iron in a small room, so we break it up in place and check the framing under it for old leak damage before the new pan goes in. On rural houses on septic, a conversion stays inside the existing bathroom and does not add a bathroom, which is what sends Woodside plans to County Environmental Health. Owners planning to stay on a property with long walks and stairs often ask for a curbless shower and grab-bar blocking, which we frame in even if the bars come later.

  • Rural homes and horse properties on one acre and up (Mountain Home Road, Kings Mountain Road, Olive Hill, Portola Road, the hills toward Skyline): Septic systems, long drives from the road, and water from Cal Water, Redwood City or a private well. Adding a bathroom brings in San Mateo County Environmental Health.
  • 1920s–30s cabin-site houses, added onto over the years (Woodside Glens, Emerald Lake Hills): Narrow, steep lots first sold for vacation cabins, many houses spread over two or more lots. The Glens have been on sewer since 1968; the town’s part of Emerald Lake Hills is on septic.
  • Mid-century ranches and 1960s–80s custom homes (Woodside Hills, Woodside Heights, Woodside Knolls and the smaller subdivisions off Cañada and Woodside roads): Single-story or split-level houses with dated original baths and closed kitchens; the most common remodels in town.
  • Large estates (Across town, on the larger parcels): Several bathrooms per house remodeled together, which is where the town’s 50% wall count matters most.

Neighborhoods we work in: Woodside Glens, Town Center, Woodside Hills, Woodside Heights, Woodside Knolls, Woodside Oaks, Emerald Lake Hills, Hidden Valley Farm, Mountain Home, Olive Hill, Kings Mountain, Sky Londa.

Septic, sprinklers and the 50% rule in Woodside

Most of Woodside is on septic; sewer reaches the Town Center, Woodside Glens and parts of the Woodside Hills area through town and county sewer districts. If a remodel adds a bathroom or a bedroom on a septic parcel, the town sends a plan set to San Mateo County Environmental Health, which reviews the system before the permit issues. The town also tracks how much of a house is altered: once removed or replaced walls reach 50% within three years, counting walls stripped to the studs, the whole house needs fire sprinklers, WUI upgrades and driveway work, and at 75% a fire hydrant within 600 drivable feet. We fill in the town’s alteration form during design, so you know where your project lands before anything is demolished.

Permits in Woodside

Town of Woodside Building Division (2955 Woodside Rd, Woodside) issues permits in Woodside. 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.

  • Title 24 energy documentation is required on permitted kitchens; we prepare the forms.
  • On septic parcels, plans that add a bathroom or bedroom go to San Mateo County Environmental Health for review, with its own application and fee, before the permit issues.
  • Every remodel files the town’s Building Alteration Calculation Form. When altered walls reach 50% within three years, the house needs fire sprinklers, WUI upgrades and driveway work; at 75%, a fire hydrant as well.
  • Interior-only work goes to a building permit. Exterior changes are checked by Planning first and can go to staff, the Architectural and Site Review Administrator or the Architectural and Site Review Board (ASRB).
  • Most of Emerald Lake Hills, and all of Kings Mountain and Sky Londa, are unincorporated and permit through San Mateo County Planning & Building, not the town.

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. A large rural house adding induction and a heat-pump water heater usually starts with a load calculation.

Tub-to-Shower Conversion questions from Woodside

How long does a tub-to-shower conversion take in Woodside?

Two to three days for an acrylic wall system, about five working days for a tiled shower, and seven to ten for curbless. The town asks for inspections to be booked 72 hours ahead, so we schedule them before the walls close.

Do I need a permit to convert a tub to a shower?

If the valve or drain moves, yes: from the Town of Woodside, or from San Mateo County if your parcel is unincorporated. A like-for-like swap on the same drain sometimes does not; we confirm before quoting.

Will a conversion affect my septic permit?

Not usually. The town’s checklist sends plans to County Environmental Health when a bathroom or bedroom is added, and a conversion inside an existing bathroom does neither.

Should I keep a tub somewhere for resale?

In a Woodside house with several bathrooms, one tub elsewhere is enough. In a smaller Glens house with one full bath, we talk through who will live there before taking the only tub out.
