Fences & Walls
Heavy RestrictionsHeight limits, materials, permits, and shared fence rules.
Height Limits
Some RestrictionsSan Angelo sets fence height through its zoning ordinance, but the hard, enforced rule is the corner sight triangle: nothing between two and nine feet tall may sit in the 30-by-30-foot triangle at street intersections.
Pool Barriers
Heavy RestrictionsSan Angelo requires a safety barrier around residential pools under its adopted 2021 building codes, and Texas Health and Safety Code Chapter 757 sets enclosure standards for apartment and shared pools: at least 48 inches tall with self-closing, self-latching gates.
Permit Requirements
Some RestrictionsA residential fence in San Angelo needs no building permit unless it stands over seven feet, under the city's adopted 2021 International Residential Code. Anyone hired to build it must be a city-registered fence contractor.
Neighbor Fence Rules
Few RestrictionsTexas has no Good Neighbor Fence Act, so in San Angelo each owner pays for and maintains their own fence. Cost-sharing is voluntary, and boundary or encroachment disputes are settled in civil court, not by the city.
Approved Materials
Some RestrictionsNo Texas law restricts fence materials, so wood, chain-link, wrought iron, vinyl, and masonry are all allowed in San Angelo. The zoning ordinance governs materials by district, and masonry or structural walls require a building permit.
Retaining Walls
Some RestrictionsUnder San Angelo's adopted 2021 building codes, a retaining wall needs a building permit once it exceeds four feet, measured from the bottom of the footing, or whenever it supports a surcharge such as a slope or driveway above it.
Swimming Pools
Heavy RestrictionsPool permits, safety fencing, and drainage requirements.
Pool Permits
Some RestrictionsA building permit is required before installing an in-ground or above-ground pool, spa, or permanent hot tub in San Angelo, issued by the Permits and Inspections Division. Construction follows the adopted 2021 ISPSC and 2021 IRC.
Hot Tub Rules
Some RestrictionsResidential hot tubs need permits for the 240-volt electrical connection and, for permanent installs, construction. A locking safety cover can satisfy the barrier. Public and semipublic spas need an annual health permit.
Above-Ground Pools
Some RestrictionsAbove-ground pools need a building permit and barrier compliance under the adopted 2021 ISPSC. A pool wall at least 48 inches high can serve as the barrier; access ladders must be removable or secured.
Safety Rules
Heavy RestrictionsPublic and semipublic pools need an annual City/County Health Department operating permit and must meet the state Standards for Swimming Pools and Spas. All pools require anti-entrapment drain covers under the federal VGB Act.
Fencing Requirements
Heavy RestrictionsResidential pools need a 48-inch barrier with self-closing, self-latching gates under the adopted 2021 ISPSC. Texas Health and Safety Code Chapter 757 adds enclosure rules for apartment-complex and property-owners-association pools.
ADUs & Granny Flats
Some RestrictionsAccessory dwelling unit rules and garage conversion permits.
ADU Rules
Some RestrictionsSan Angelo allows one detached accessory apartment on a single-family lot in the RS-2 or RM-1 district. It must be under 900 square feet, owner-occupied, and on a home at least five years old.
Garage Conversions
Some RestrictionsConverting a garage to living space needs a building permit and must keep the required off-street parking. San Angelo expressly allows converting a detached garage into an accessory apartment where Sec. 401 standards are met.
Sheds & Outbuildings
Some RestrictionsShed permits, setback limits, and outbuilding size rules.
Tiny Homes
Some RestrictionsSan Angelo has no dedicated tiny-home ordinance. A foundation-built small home must meet zoning district and building-code standards; homes on wheels are treated as RVs or manufactured homes under Code Article 12.03.
Shed Rules
Few RestrictionsDetached accessory buildings on a residential lot are capped at 600 square feet or 50 percent of the main house, whichever is greater. The adopted 2021 IRC exempts tool sheds of 200 square feet or less from a building permit.
Carport Rules
Some RestrictionsA carport's supporting structure cannot stand in a required front or side yard unless it sits in an Open Structure overlay or is approved by variance. Carports built before March 1995 may be grandfathered.
Fire Pits & Outdoor Structures
Heavy RestrictionsFire pit placement, outdoor burning restrictions, and permits.
Outdoor Burning
Heavy RestrictionsSan Angelo strictly limits open burning. Ground fires are prohibited (Sec. 6.06.005), open burning must stay 350 feet from structures, and burning construction materials, trash, or treated wood is banned under TCEQ rules. Tom Green County burn bans routinely halt all outdoor burning.
Fire Pit Rules
Some RestrictionsSan Angelo permits recreational fires and fire pits but limits fuel to 3 feet in diameter and 2 feet high (Sec. 6.06.002). Fires in approved containers must sit at least 15 feet from any structure. Tom Green County burn bans suspend all open burning.
Landscaping & Tree Removal
Heavy RestrictionsTree removal permits, heritage tree protections, and water rules.
Tree Trimming
Some RestrictionsSan Angelo requires owners to trim trees overhanging sidewalks, streets, and alleys so branches don't block travel (Sec. 7.02.031), and to keep hedges clear of public sidewalks (Sec. 7.02.032).

General Permit Tips
When do you typically need a permit?
Most cities require permits for structural work, including fences over a certain height, pools, ADUs, and sheds above a size threshold. Even projects that seem minor can trigger permit requirements, so it is always best to check first.
How to apply for a building permit
Visit your local building department or their website. Most jurisdictions accept online applications. You will typically need a site plan, project description, and may need contractor information. Processing times vary from same-day for simple projects to several weeks for larger builds.
Common permit violations to avoid
Building without a permit, exceeding approved dimensions, and ignoring setback requirements are the most common violations. Penalties can include fines, required removal of the structure, and complications when selling your home.
