Summary

Unincorporated San Diego County caps building height by zone designator under the Zoning Ordinance Height Schedule, ranging from 15 feet and one story up to 60 feet; anything taller requires a Major Use Permit.

City-specific rules exist: Chula Vista, Bostonia, El Cajon, Carlsbad, San Marcos, Vista, Escondido, Oceanside, and San Diego have their own structure height limits rules that differ from San Diego County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Notes: (a) Any number of stories is permitted, provided all building code requirements and floor-area ratio limitations are met. (b) Greater than 60 feet. Any height in excess of 60 feet requires a Major Use Permit.

Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-141: Administrative: Current through Ord. No. 11007 (N.S.), effective 7-10-26 | Regulatory: Current through Ord. No. 11008 (N.S.), effective 7-24-26).

Full Breakdown

The county's Height Regulations (Zoning Ordinance Sections 4600 through 4620) assign each zone a letter designator from Schedule B at Section 4610, setting maximum feet and stories, from 15 feet and one story for designator A up to 60 feet for designators P and Q, with anything taller requiring a Major Use Permit under designator R. Height is measured in both feet and number of stories. Section 4615 permits an extra story on steep downhill lots, or for a main dwelling via an Administrative Permit if compatibility and view findings are met. Section 4620 exempts items like flagpoles, antennas and chimneys from the cap.

Violations & Fines

Building Permits are issued against the zone's height designator; construction exceeding it without an approved Major Use Permit or Administrative Permit is non-compliant and subject to County Planning & Development Services enforcement and correction.

Frequently Asked Questions

What is the height limit for a house in unincorporated San Diego County?
It depends on the parcel's zone designator under Schedule B (Section 4610): many single-family residential zones allow 30-35 feet and two to three stories.
Can I build taller than 60 feet?
Only with a Major Use Permit. Designator R in Schedule B allows over 60 feet solely through that discretionary permit process.
