This guide walks you through everything from the permit fees, fence height limitations, prohibited materials, development services, and how to apply for a permit application. Whether you’re repairing an existing fence or erecting a totally new fence, this will help you decide and start working confidently.
Why You Need a Fence Permit San Antonio
In San Antonio, any fence construction whether residential or commercial inside the city of San Antonio city limits generally requires a building permit. The Development Services Department handles these permits. The regulations come from the Unified Development Code, specifically Section 35‑514 in most recent updates.
If you build or repair a fence without the required permits, the city could impose penalty permit fees, demand alterations, or even order removal. The fence laws are in place to enforce safety, property aesthetics, traffic safety for clear vision, and to ensure materials and construction are up to approved standards. Also, in historic districts or conservation overlay zones there are additional reviews and constraints.
When Is a Building Permit Required
New Fence
If you plan to build a brand new fence, you almost certainly need to apply for a permit through San Antonio’s Development Services Department. The permit application must go through the BuildSA portal, the online system for the city.
Repair or Replacement of Existing Fence
If you are repairing or replacing an existing fence, a fence permit San Antonio rules require a permit if the work exceeds 25 percent of the length of the existing fence. If less than 25 percent is replaced or repaired, you may not need one unless local circumstances or other city or ordinances require it.
Projects That Might Not Require a Permit
Some fence repair, cosmetic maintenance, or gate adjustments may fall under general repairs that do not require a permit. The Development Services Department publishes a “No Permit Required” list for minor work. However, anything structural, anything changing height, material, location, or affecting safety or sight lines likely requires the building permit.
Fence Height, Design Rules, and Prohibited Materials
Fence Height in Front Yards
Front yards in San Antonio are held to stricter fence height rules. A solid fence such as wood, vinyl, or masonry in front yards is limited to 3 feet in height. If the fence is open or decorative, such as chain link or wrought iron, the height limit is 5 feet in front yards.
Side and Backyard Fences
For side and rear yards, the standard maximum fence height is 6 feet. In some cases exceptions allow up to 8 feet. Those exceptions apply if certain conditions are met, such as when the property abuts a commercial, industrial, multi‑family or park use, or when the lot is sloped and the highest point of the fence measured does not exceed 8 feet above grade.
Fence Height Exceptions
The Unified Development Code allows exceptions when engineering justifies higher structure, or where specific elevation differences, abutting land uses, or slope conditions apply. Property owners may request special review or variance approval depending on the scope of the project.
Prohibited Materials
San Antonio has defined prohibited materials for fences. You may not use sheet metal, roll metal, corrugated metal, particle board, plastic sheeting, tarps, cast-off or secondhand materials, barbed wire or razor wire in residential fences, low grade plywood, or materials not intended for fencing. These local laws are strict because they affect safety and durability.
Other Design Rules: Clear Vision, Placement, Materials
Fences near corners, alleys, or driveways must follow clear vision rules so drivers and pedestrians can see approaching traffic. Placement must respect property lines and avoid installing over easements unless approved. The fence setback in many residential cases can be right on the property line, but you must verify boundary details. Materials must be durable and consistent with city code.
Permit Fees and Application Process
Permit Fees
The fee for a residential fence permit San Antonio cost is about $26.50 if you apply online, or $36.50 in person at the One Stop office. There are additional surcharges or processing fees in some cases.
Application Process Step by Step Guide
Here is a step by step guide for how homeowners or contractors can complete the permit application process:
- Verify your zoning district and whether your property is platted, within city of San Antonio city limits, or falls into a historic district or flood zone.
- Prepare a site plan that shows property boundaries, existing structures, proposed fence location, fence height, fence materials, any easements, setbacks, and required spacing.
- If required, gather any additional documents such as proof of ownership, tree affidavit for vacant lots, or historic district review if applicable.
- Apply online via the BuildSA portal or in person at the One Stop, also known as the Business Services Center located at the Cliff Morton Development and Business Services Center at 1901 S Alamo St.
- Upload all required documents in PDF format. Pay the permit fees. Submit the permit application.
- Wait for City of San Antonio review by the Development Services Department. Typically, most fence permits are approved within two business days if submitted online. If submitted in person, some permits can be approved same-day for basic work.
Resources and Where to Go

How Fence Permit San Antonio Rules Impact Your Proposed Home Project
If you plan a proposed home project which includes a fence installation, or if it is an existing fence you intend to repair or replace, observing these rules will matter in several ways:
- Budgeting: Permit fees, material costs, contractor pricing, and design adjustments for prohibited materials or fence height limits all affect project cost.
- Timeline: Waiting for reviews in historic districts, flood zones, or for inspections or document verification can add business days.
- Material choices: Using materials that the city allows such as wood, chain link, masonry, or decorative metals instead of prohibited materials like barbed wire or razor wire.
- Compliance: Ensuring fence height, structure, and placement are legal before you start working avoids enforcement actions, fines, or corrections later.
Common Mistakes Homeowners Make
- Deciding on a fence design without verifying whether their property is inside historic districts, flood zones, or city limits.
- Choosing prohibited materials like roll metal, tarps, or razor wire and having to remove them later.
- Ignoring the 25 percent replacement rule for an existing fence, thinking that repairs do not require permits.
- Failing to prepare all the required documents like site plans or affidavits.
- Starting construction before permit application is approved and before completing the full review process.
