Summary
San Marcos strikes the standard height exemption for fences, so a building permit is required to build a fence in the city: there is no low-fence carve-out.
Sec. 14.041. Amendments. Section 101.5.1 Any project located in the Extraterritorial Jurisdiction that will be provided water, wastewater or electric utilities by the City of San Marcos is required to obtain a building permit and comply with all applicable building code requirements. Section R103 is deleted. Section R105.2 Building Exemption #2 is removed.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 41).
Full Breakdown
San Marcos amended its adopted Residential Code so fences no longer qualify for the model code's routine permit exemption: Sec. 14.041 removes "Building Exemption #2" from Section R105.2 of the 2021 International Residential Code, the clause that otherwise waives a permit for shorter fences. The same strike applies to the commercial-side International Building Code under Sec. 14.026. Practically, a homeowner or contractor should apply for a building permit before erecting a fence anywhere in the city, including its extraterritorial jurisdiction where the city supplies water, wastewater, or electric service (Sec. 14.041, citing Section 101.5.1).
Violations & Fines
Building without a required permit is enforced under the city's general Code penalty: a fine up to $500.00 per Sec. 1.015(b), with each day of an ongoing violation a separate offense under Sec. 1.015(d).
