How Redwood City Handles Swimming Pools & Spas: A Practical Guide

Redwood City maintains 38 local ordinances across all categories, and 3 of those deal specifically with swimming pools & spas. Here is a breakdown of what the city actually requires, what is prohibited, and where Redwood City falls on the strict-to-permissive spectrum compared to other cities.

Fencing Requirements

Pool fences in Redwood City must be greater than 5 feet high (California requires minimum 60 inches), self-latching, self-closing, with no climbable protrusions, vertical ground clearance under 2 inches, and no gaps over 4 inches.
