Seal Beach reviews ADU applications ministerially under California state law, which means no neighborhood hearing is required and the city must approve or deny a complete application within 60 days. The city follows state standards, including detached ADUs up to 1,200 square feet and no added parking for units within a half mile of transit, and under AB 670 an HOA cannot prohibit an ADU.

Local Insight
Seal Beach's small-town beach community character and coastal proximity create solid ADU rental demand. Coastal zone properties may require a CDP; AB 462 (eff. Oct 2025) places that review on a 60-day ministerial clock.

As of August 2026. Source: California HCD ADU Handbook (March 2026) & 2025–26 state legislation (SB 543, SB 1211, AB 976, AB 1154, AB 462, AB 1033, AB 2533). California state law sets the minimum floor — local jurisdictions in Seal Beach may add design, setback, or other requirements on top of these state standards.
