San Marcos limits front yard fences and walls to 42 inches (3.5 feet) in height. Side and rear yard fences may be up to 6 feet, with freestanding masonry walls up to 7 feet allowed without a building permit but subject to city standards. Fences above 6 feet require planning department approval.
San Marcos zoning ordinance (Title 20) restricts fence and wall heights by location on the property. Front yard fences and walls are limited to 42 inches (3.5 feet) to maintain visibility and neighborhood character. Side and rear yard fences may be up to 6 feet in height. Wood fences and freestanding masonry walls up to 7 feet do not require a building permit but must conform to city standards. Fences and walls exceeding 6 feet in height require approval from the Planning Department. On corner lots, fences in the sight visibility triangle must comply with reduced height requirements to ensure traffic safety. All fences must be maintained in good condition.
Fences exceeding height limits without approval may result in code violations and required removal or modification. Contact Development Services at (760) 744-1050 x3233 or Code Enforcement at (760) 744-1050 x3234.
