Planning sequence
01
Start with Planning, not Building
The City's Building & Safety FAQ says Planning regulates use, location, aesthetics and allowable building size, including Zoning Clearance, Hillside Reviews, Director Reviews and Design Reviews, and that projects are typically reviewed by Planning before Building & Safety.

02
Know the risk of applying in parallel
A building permit application can be filed at the same time as a Zoning Clearance, but the FAQ calls this 'at risk': no permit is issued until Planning entitlements are approved, and some fees may not be refunded if plans change.

03
Ask which R-1 code version applies
The City's August 2026 flyer says the single-family zoning update keeps building height, setbacks and allowable floor area unchanged, adds minimum lot dimensions, clarifies retaining walls, fences and gates, and adds new limits on basements. Confirm with Planning whether the update is in effect on your application date.
