Homes we remodel in Redwood City

Most Redwood City conversions are in a hall bath where the tub has not been used in years. In Mt. Carmel and the other prewar neighborhoods the tub is often cast iron, which we break up in place to get it out of a small room, and the floor framing gets checked before the new pan goes in. In Woodside Plaza, where the house may have only one bathroom, an acrylic system that is done in two or three days keeps the family showering at home. In Redwood Shores condos the shower sits over a neighbor’s ceiling, so the pan is flood-tested for 24 hours and the HOA approves the work first. Owners planning to stay ask for a low or curbless entry and grab-bar blocking, which we frame in even if the bars come later.

  • Prewar cottages and bungalows (Mt. Carmel, Stambaugh-Heller, Centennial, Palm Park, Central): Small single-story houses, many with a detached garage out back. Expect cast-iron drains, older wiring and an original bathroom that has been patched more than remodeled.
  • Early-1950s tract homes (Woodside Plaza and nearby streets off Woodside Road): Houses of around 1,000 square feet that were often built with one bathroom, so a full hall-bath gut or adding a second bath is the usual project.
  • Mid-century hillside homes (Farm Hill, Eagle Hill, Canyon, and Emerald Hills in the county): Sloped lots and longer carries from the street. Emerald Hills began as 1920s summer cabins and is unincorporated, so permits go to San Mateo County.
  • 1960s-onward townhomes, condos and houses on bay fill (Redwood Shores): Stacked units where a leak reaches the neighbor below, HOA approval before work starts, and a levee-protected area where parts are mapped as FEMA flood zones.

Remodeling in Redwood Shores

Redwood Shores was built from the 1960s on filled bay land that had been salt ponds, and most of it is townhomes and condos with some single-family streets. A bathroom or kitchen there usually starts with the HOA: approval of the scope, work hours, parking and how materials come in. In a stacked unit the bathroom sits over a neighbor’s ceiling, so we flood-test every shower pan for 24 hours before tile. The area is protected by a levee the city is upgrading, and parts are mapped as FEMA flood zones; a single bathroom or kitchen rarely reaches the substantial-improvement threshold, but we check the numbers on a larger project. Permits go to the City of Redwood City Building Division.

Permits in Redwood City

City of Redwood City Building Division (1017 Middlefield Rd, Redwood City) issues permits in Redwood City. Typical review time: about 3–4 weeks for residential alterations on the city’s published estimate; interior remodels can qualify for a One Stop review appointment. We confirm the current time 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.

  • Redwood City takes permit applications electronically only; we prepare and upload the drawings and forms.
  • Interior residential remodels are eligible for the city’s One Stop plan review, where a complete project can be approved at the appointment.
  • Emerald Hills (Emerald Lake Hills), North Fair Oaks, Kensington Square and Palomar Park are unincorporated and permit through San Mateo County Planning & Building at 455 County Center, not the city.
  • Redwood Shores sits behind a levee that the city is upgrading for FEMA accreditation, and parts of it are mapped as flood zones; on large projects we check the substantial-improvement rule.

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, and the city has run its own heat-pump rebates.

Tub-to-Shower Conversion questions from Redwood City

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

Two to three days for an acrylic wall system, about five working days for a tiled shower, and seven to ten for curbless. Permit timing is separate.

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

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

Can you do a curbless shower in a Redwood Shores condo?

Sometimes. It depends on the floor structure and what the HOA allows below the unit, so we look before promising one. A low-threshold pan is the fallback.

Should I keep a tub if it is our only bathroom?

If you have small children or plan to sell soon, probably yes. If not, a shower is easier to use every day, and a second bath can keep a tub later.
