San Francisco, CA Fence Regulations: Height Limits (2026)

Section 136 of the San Francisco Planning Code, titled 'Obstructions Over Streets and Alleys and in Required Setbacks, Yards, and Usable Open Space,' is the controlling provision for fences. Subsection 136(c) enumerates the structures and features permitted as obstructions in yards and required setbacks, and fences are listed among those permitted obstructions. Within any required front setback, fences, walls, and hedges are limited to 3 feet in height to preserve light, air, and the streetscape. In required rear yards and side yards, fences may be erected up to 10 feet in height as a permitted obstruction under Section 136(c). Height is generally measured from the adjoining grade. Under the San Francisco Building Code (which adopts the California Building Code), fences 6 feet or less in height are typically exempt from a building permit, but fences taller than 6 feet, retaining walls combined with fencing, and pool enclosures require a building permit from the Department of Building Inspection. Properties within designated historic districts, Article 10/Article 11 landmark properties, or RH/RM zones with special design requirements may need Planning Department review (Section 311 neighborhood notification can apply to certain alterations). Swimming pool enclosures must also satisfy California Health & Safety Code 115920 et seq. (the Pool Safety Act). Lots adjoining streets at corners must maintain corner sight-clearance under Public Works rules.
