USA Site Plans
If you are applying for a residential permit in San Antonio, a clear site plan can help show exactly where your project will be located on the property. This is especially important for sheds, garages, pools, home additions, carports, decks, covered patios, fences, and other exterior improvements where the city needs to review lot layout, setbacks, existing structures, and proposed work.
At USA Site Plans, we prepare residential site plans for San Antonio permit applications. Send us your address, survey, sketch, photos, measurements, or permit comments, and we can draft a clean site plan showing the property lines, existing structures, proposed project, dimensions, and distances to lot lines.
Order online, upload your property details, and get a clear residential site plan for your shed, garage, pool, addition, carport, deck, or permit project.
Why a Site Plan Matters for a San Antonio Permit
A site plan, sometimes called a plot plan, shows the property from above. It helps the permit reviewer understand the full lot, the existing house, detached structures, driveway, sidewalks, easements, and the proposed work. Instead of only describing your project, the site plan shows where it will be built.
The City of San Antonio Development Services Department says that residential building permits are issued for properties located within city limits. The city also explains that a building permit is typically required when you build, remodel, repair, or demolish a structure on your property. Source: City of San Antonio — Residential Permits.
For new residential structures, room additions over 1,000 square feet, or second-floor additions, San Antonio says applicants must submit a site plan showing the entire lot, existing structures on the lot, proposed construction, and distances to all property lines.

What Should Be Included on a San Antonio Residential Site Plan?
A good residential site plan should be simple, accurate, and easy to read. The goal is to help the reviewer quickly understand the project location and how the work fits on the property.
A typical San Antonio permit site plan may include:
- Property address and basic project information
- Lot lines and lot dimensions
- North arrow and drawing scale
- Existing house, garage, shed, driveway, walkways, patio, pool, and other structures
- Proposed shed, garage, pool, addition, carport, deck, patio cover, fence, or other work
- Distances from proposed work to all property lines
- Distances between existing and proposed structures when needed
- Front, side, and rear setback information when available
- Driveway, street, sidewalk, alley, and access locations
- Easements or special site limits if shown on the survey or plat
- Clear labels for existing and proposed improvements
- Tree, floodplain, historic, or overlay notes when relevant
San Antonio’s plan review page says residential reviews may include building, zoning, and tree preservation review. Additional review may apply if the property is in a Neighborhood Conservation District, Corridor Overlay District, floodplain, or historic area. Source: City of San Antonio — Plan Review.
Common San Antonio Projects That May Need a Site Plan
San Antonio has a residential improvement permit process for many common homeowner projects. These projects often need a site plan because they affect the property layout, structure location, setbacks, access, or inspections.
| Project Type | What the Site Plan Helps Show |
|---|---|
| Shed or Accessory Building | Shed size, location, distance to property lines, distance to the house, and setback compliance. |
| Garage | Garage footprint, driveway access, distance to lot lines, distance to the home, and access layout. |
| Swimming Pool or Spa | Pool location, equipment area, barriers, gates, alarms, setbacks, easements, and nearby structures. |
| Home Addition | Existing house footprint, proposed addition, property line distances, and overall lot layout. |
| Carport | Carport location, dimensions, driveway connection, property line distances, and setback clearances. |
| Deck or Covered Patio | Deck or patio cover location, attachment to the home, stairs, posts, dimensions, and setbacks. |
| Fence | Fence location, height notes, gates, property lines, street-facing sides, and corner lot conditions. |
San Antonio’s Residential Improvement permit materials define this permit type as applying to accessory buildings, home additions, carports, covered patios/porches, decks, and swimming pools. The same city material lists accessory buildings including sheds and garages, home additions under 1,000 square feet, carports, decks, covered patios/porches, and swimming pools or spas as residential improvement permit subtypes.

Shed and Accessory Structure Site Plans in San Antonio
For sheds and accessory structures, the main questions are usually size, placement, and setbacks. The city needs to see where the structure sits on the lot and how far it is from property lines and other buildings.
San Antonio’s no-permit-required list says one-story detached accessory structures used as tool sheds, storage sheds, playhouses, and similar uses may be exempt from permit requirements if the floor area does not exceed 300 square feet and the structure complies with setback requirements in the Unified Development Code. Source: City of San Antonio — No Permit Required List.
The city’s homeowner FAQ also says a permit is required to build an accessory structure greater than 300 square feet, and that building setbacks apply. Source: City of San Antonio — Getting Started with Development Services.
Garage and Carport Site Plans in San Antonio
A garage or carport site plan should show the proposed structure, driveway or access route, distance to property lines, and relationship to the existing house. If the garage is detached, the reviewer may also need to understand the distance between structures and how vehicles enter the property.
San Antonio’s Residential Improvement permit materials list accessory buildings, including garages, as a residential improvement permit subtype. The city’s homeowner FAQ also says a permit is required to build a carport and that carports must meet building setbacks. Source: City of San Antonio — Residential Improvement Permits and City of San Antonio — Getting Started.
Pool and Spa Site Plans in San Antonio
Swimming pool and spa site plans often need more detail than a simple shed or patio plan. In addition to the pool location, the plan may need to show barriers, gates, alarms, equipment, easements, and distances to property lines and existing structures.
San Antonio’s Residential Swimming Pool or Spa Permit Application says the site plan must be drawn to scale and show the size of the lot, existing structures, easements, the proposed swimming pool or spa, and distances to adjacent property lines and existing structures. It also says the plan should clearly label swimming pool barriers, audible alarms, and self-closing gates with locking mechanisms. Source: City of San Antonio — Residential Swimming Pool or Spa Permit Application.
Addition Site Plans in San Antonio
Home additions usually require a clear site plan because they change the building footprint. The plan should show the existing house, the proposed addition, the lot lines, and the distances from the addition to all property lines.
San Antonio says all additions require a permit. The city’s homeowner FAQ also says additions over 1,000 square feet and second-story additions require construction plan review, and that foundation designs and inspections require an engineer. Source: City of San Antonio — Getting Started with Development Services.
Site Plan vs. Survey: What Is the Difference?
A survey is usually prepared by a licensed surveyor and shows legal property information such as property boundaries, lot dimensions, easements, and existing improvements. A site plan uses property information to show the current layout and proposed work in a permit-friendly drawing.
If you already have a survey or plat, it can be a very helpful starting point. San Antonio’s IB 101 Residential Packet tells applicants to obtain a copy of the plat from Bexar County, a pre-recorded plat in review with DSD, or a Certificate of Determination from Land Development stating that platting is not required. Source: City of San Antonio — IB 101 Residential Packet.
If San Antonio requires a current survey, sealed foundation plan, engineer plan, architect plan, drainage document, or other professional drawing for your specific project, you should follow that requirement. Our service is for residential site plan drafting and layout support.
Special Conditions That Can Affect Your San Antonio Site Plan
Some properties need extra review because of location or site conditions. This does not apply to every project, but it is important to check early.
San Antonio’s residential plan review page says additional reviews may be assigned for properties in a Neighborhood Conservation District, Corridor Overlay District, other design zoning district, floodplain, or historic area. It also says standard residential construction project reviews include building, zoning, and tree preservation. Source: City of San Antonio — Residential Plan Review.
The IB 101 Residential Packet also tells applicants to check for floodplain conditions, historic district requirements, easements, addressing, zoning, and whether street construction plans are needed if the property is on an unpaved street or next to a city right-of-way with no existing road.

- Property lines are not shown clearly
- Lot dimensions are missing
- No north arrow or drawing scale
- Existing structures are missing or not labeled
- Proposed shed, garage, pool, addition, or carport is not clearly marked
- Distances to property lines are missing
- Driveway, sidewalk, street, or access route is not shown
- Easements shown on the survey or plat are not included
- Pool barriers, gates, alarms, or equipment are missing from pool plans
- The site plan does not match the permit application description
- The plan ignores special conditions such as floodplain, historic district, overlay district, or tree preservation review
FAQ: San Antonio Site Plans for Permits
