Permit guide

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

Yes, a deck in Foster City almost always needs a permit. The City amended the California Residential Code, and its exemption section no longer lists size or height limits for decks. We treat every deck as a permit project.

Confirm the requirement with the Building Division before you plan. We confirm it for your property and handle the permit.

Permit requirements for a deck in Foster 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. Building Division: (650) 286-3231.

Setbacks and zoning

  • Typical R-1 setbacks: front 20 ft; interior side 5 ft; street side 10 ft; rear 20 ft (Sec. 17.12.040).
  • A deck more than 6 inches above grade must be at least 2 ft from any property line (Sec. 17.15.050(B)).
  • A deck or patio 3 ft or more above grade must be at least 5 ft from any property line (Sec. 17.15.050(B)).
  • A deck more than 12 inches above grade needs skirting to hide the gap, unless the yard is fully enclosed by a fence of at least 6 ft.
  • Lots with a PD suffix follow their own development plan, so the numbers can differ.
  • Your zoning district sets the exact numbers, so we confirm them before we 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.
