Permit guide

Do I need a permit to build a deck in Redwood City?

In most cases, yes. Redwood City follows California Residential Code R105.2 and exempts only low, free-standing decks:

  • Under 30 inches above grade
  • Under 200 square feet
  • Not attached to the house
  • Not serving the exit door

A deck attached to the house needs a building permit at any height. Even an exempt deck must still meet the City’s zoning setbacks, and the zoning threshold is lower, at 12 inches above grade. We confirm the requirements for your property and prepare the plans.

Permit requirements for a deck in Redwood City

Requirements vary by project. For a typical deck we prepare:

  • Building permit application
  • Site plan showing the deck and property lines
  • Floor plan, framing plan and elevations
  • Structural details for footings, framing and railings
  • Structural calculations when an engineer is required
  • Product and material information

What the City checks

  • Structure: footings, framing, connections and loads
  • Guardrails and stairs
  • Compliance with the California Residential Code
  • Setbacks and lot coverage
  • Inspections during construction

How long it takes

Timing depends on the City’s review queue and on any comments that come back. Ask our team for the current estimate. Redwood City Building Inspection Division: (650) 780-7350.

Setbacks and zoning

  • Typical R-1 setbacks: front 15 ft (20 ft to a garage); interior side 6 ft or half the wall height, whichever is greater; street side 15 ft; rear 20 ft. Narrow lots have reduced side setbacks.
  • An open, unroofed deck can project up to 3 ft into a yard as an architectural feature, if it stays at least 3 ft from the property line and has no supporting structural members (Sec. 32.3(E)).
  • Lot coverage in R-1 is limited to 40%. Your zoning district and any HOA rules should be confirmed before design.

We handle it for you. Techwood Decks prepares the drawings, submits the permit and manages the inspections, so you do not have to deal with the City.
