Do I Need a Permit to Build a Shed in Texas?

Texas Has No Statewide Shed Permit Rule

Texas is one of the few states that does not adopt or enforce a statewide residential building code. The state government leaves building code decisions entirely to cities and counties. That means the permit threshold for building a shed in Houston is different from the threshold in San Antonio, which is different again from Fort Worth.

This isn't a minor technicality. The exempt shed size ranges from 120 square feet in Houston to 300 square feet in San Antonio, and Fort Worth requires a permit for every shed regardless of size. Two homeowners building the same 150-square-foot shed on opposite sides of a city boundary could face completely different requirements. You need to check your specific city's rules before you buy materials or pour a foundation.

The International Residential Code (IRC), which forms the basis for most local building codes in Texas, exempts one-story detached accessory structures under 200 square feet used for storage, tool sheds, and similar purposes. Many Texas cities follow this baseline closely, but some are stricter (Houston at 120 square feet) and some are more lenient (San Antonio at 300 square feet). Fort Worth ignores the IRC exemption entirely for sheds.

How the Five Largest Texas Cities Handle Shed Permits

Despite the lack of a state code, a clear pattern emerges across most Texas cities: small sheds used for basic storage, without electricity or plumbing, built on non-permanent foundations, and placed in the rear yard are the easiest to build without a permit. The moment a shed gets larger, gains utilities, sits on a concrete slab, or moves toward the front of the property, permit requirements kick in.

Houston: 120 Square Feet

Houston's building code exempts one-story detached accessory structures with a floor area of 120 square feet or less from a building permit. That threshold comes from the city's local amendments to the 2021 International Building Code, and it is lower than the 200-square-foot exemption that most Texas cities use.

The 120-square-foot limit is firm. A 10x12 shed is the largest standard size that fits within the exemption. If you want anything bigger — a 12x16 workshop, a 14x20 storage barn — you need a permit through the Houston Permitting Center.

Houston has no traditional zoning ordinance, which means there are no city-imposed front-yard or setback restrictions on sheds from the zoning side. However, deed restrictions enforced by civic clubs and homeowners associations fill that gap in most Houston subdivisions. Before placing a shed, confirm that your subdivision's deed restrictions allow accessory structures and check for any size, material, or placement restrictions. The City of Houston Legal Department enforces certain deed restrictions, and the Harris County Clerk's office at (713) 274-8680 can help you locate the restrictions on your property.

Houston's floodplain rules add another layer. If your property is in a FEMA-designated flood zone, any structure — including a small shed — may require a floodplain development permit. The greater Houston area has extensive 100-year floodplains, particularly in neighborhoods like Meyerland and Kingwood. A shed in a floodplain can redirect water flow and cause damage to neighboring properties, so the city takes this seriously.

Note that Harris County (unincorporated areas outside Houston city limits) uses a different threshold: sheds under 150 square feet used for temporary storage of materials or equipment are exempt.

San Antonio: 300 Square Feet

San Antonio has the most generous shed exemption among major Texas cities. The city's building code, Chapter 10, exempts one-story detached accessory structures used as tool and storage sheds, playhouses, and similar uses with a floor area of 300 square feet or less. That means a 12x24 shed or a 15x20 workshop can go up without a building permit, as long as it has no utilities and is not used as living space.

When a permit is required — for sheds over 300 square feet — the fee is $150 for structures up to 500 square feet. The city requires a foundation inspection by a licensed engineer, a framing inspection, and a final inspection. If the space is insulated, an insulation inspection is also required.

San Antonio's Development Services Department handles permits through the BuildSA online portal. Setback requirements are determined by your property's zoning classification. The city's Unified Development Code sets general standards, but specific distances depend on the zoning district. As a general guideline, accessory structures must maintain a setback from side and rear property lines, and they cannot be placed in the front yard.

Dallas: 200 Square Feet

Dallas follows the IRC standard. Chapter 52, Section 301(b) of the Dallas City Code exempts utility buildings with a floor area of less than 200 square feet, without utilities, on single-family or duplex lots. "Without utilities" means no electrical, plumbing, or gas connections.

Dallas is a fully zoned city, so even if your shed is small enough to skip the building permit, you still need to comply with zoning setback requirements. Accessory structures in Dallas must maintain an 8-foot clearance from the house and 15 feet from other structures, though exact setbacks depend on your lot's zoning designation. Sheds are not permitted in the front yard.

Historic districts, conservation districts, and planned development districts in Dallas have additional requirements beyond the standard code. If your property falls within one of these overlay districts, you may need a Certificate of Appropriateness or other approval even for a shed that would otherwise be exempt from a building permit.

Permit fees for sheds that do require a permit are based on the project's estimated construction value. For a typical residential shed, expect fees starting around $175.

Austin: 200 Square Feet and 15 Feet Tall

Austin exempts one-story detached accessory structures that are no more than 200 square feet in floor area, no more than 15 feet in height, contain no plumbing, and are not located within a flood hazard area. The flood hazard restriction is significant — Austin has substantial flood-prone areas, and any shed in or near a 100-year floodplain loses its exemption and requires a permit with floodplain review.

Austin's exemption is also specific about plumbing. The city's code says the structure must contain "no plumbing" to be exempt. Electrical work is handled separately: even if the shed itself is exempt from a building permit, adding any electrical wiring, outlets, or lighting requires a separate electrical permit from a licensed electrician. This is a common source of confusion — the shed is exempt, but the wiring is not.

For sheds over 200 square feet, Austin requires a full residential building permit with plan review. Applications go through the Austin Build + Connect (AB+C) portal. Accessory structures over 200 square feet require a site plan showing the shed's location relative to property lines and setbacks. If the structure exceeds 20 feet in height or is more than one story within the Residential Design and Compatibility Standards boundaries (Subchapter F), the plans must be sealed by a Texas-registered architect or certified building designer.

Fort Worth: All Sheds Need a Permit

Fort Worth is the outlier. The city requires a building permit for all storage sheds, regardless of size. A 6x8 garden shed and a 20x30 workshop go through the same permitting process — the only difference is the scope of review.

Fort Worth's zoning ordinance (Chapter 5, Article 5.301) adds strict rules about accessory structures on residential lots. Non-habitable accessory buildings are limited to one story and cannot exceed the height of the primary residence. They can have an attic or loft, but only if the loft does not contain heated or air-conditioned floor space. The number and total square footage of accessory structures allowed on a lot depends on the lot size — homes on lots under one acre are limited to two accessory structures.

The zoning rules also restrict placement. Accessory structures cannot be located in the front yard and must meet minimum setback requirements for the applicable zoning district. Fort Worth's Development Services Department at (817) 392-2222 can walk you through the requirements for your specific property.

Permit fees are calculated based on the project's estimated construction value. The city offers both in-person and online permitting through its development services portal.

Setbacks, Easements, and Placement Rules

Even when a shed is exempt from a building permit, every Texas city enforces rules about where it can go on your property. These rules apply regardless of shed size.

Setbacks define the minimum distance between your shed and the property lines. While the exact numbers vary by city and zoning district, a common pattern across Texas is 5 feet from side and rear property lines for structures under 15 feet tall, and 25 feet from the front property line. If the shed is taller than 15 feet, the rear setback often increases to 10 feet.

Most Texas cities prohibit sheds in the front yard entirely. This is a zoning restriction, not a building code issue, which means it applies even to permit-exempt sheds. A few cities make exceptions for lots with unusual configurations, but in general, your shed needs to go in the side or rear yard.

Easements are the most common trap for shed placement. You cannot build a shed within a recorded utility easement without written permission from every entity that holds rights to the easement. Utility companies need access to buried lines, and a shed blocking that access can be ordered removed at the homeowner's expense. Easement locations are shown on your property's plat, which you can obtain from the county clerk's office.

Impervious cover limits matter in cities like Houston and Austin. A shed with a concrete slab foundation counts toward your lot's total impervious coverage. Houston limits residential lots under 15,000 square feet to 65% impervious cover, and exceeding that threshold triggers additional stormwater review. Austin has similar impervious cover restrictions tied to its watershed protection ordinance. A gravel pad or pier foundation may help you stay within these limits.

When Foundation Type Triggers a Permit

The type of foundation under your shed can determine whether you need a permit, independent of the shed's size.

A concrete slab is generally treated as a permanent foundation. In several Texas cities, pouring a concrete slab for a shed triggers a permit requirement even if the shed itself is below the square footage exemption. The logic is straightforward: a concrete slab requires excavation, grading, and potentially drainage considerations that the city wants to inspect.

Non-permanent foundations — concrete blocks, gravel pads, timber skids — are treated more leniently. A shed sitting on concrete blocks or wooden skids is easier to move and has less impact on drainage patterns, so most cities don't require additional review for these foundations when the shed falls within the exempt size.

This distinction matters most for pre-built sheds. Many homeowners assume that a pre-fabricated shed delivered on a truck and set on the ground is automatically exempt from permits. It's not. Texas cities evaluate the finished structure on the lot, not how it was manufactured. A pre-built 16x20 shed on skids still exceeds every Texas city's size exemption and requires a permit, the same as a site-built shed of the same dimensions.

Utilities Always Require a Permit

This is the most universal rule across Texas: adding electrical, plumbing, or mechanical systems to a shed requires a permit, regardless of the shed's size or whether the structure itself is exempt from a building permit.

Running a single electrical circuit to power a light and an outlet in your 10x10 shed requires an electrical permit issued to a licensed electrician. The electrician pulls the permit, does the work, and the city inspects the wiring before it can be energized. The same applies to plumbing (running a water line or drain) and mechanical work (installing HVAC).

This catches many homeowners off guard. They build a small shed without a permit — correctly — and then wire it for electricity without one. The shed was legal; the wiring was not. If a code enforcement officer spots the unpermitted electrical work, the homeowner can face fines and be required to open walls for inspection.

The practical takeaway: if your shed will have any utilities at all, plan to pull at least a trade permit for the relevant work, even if the shed itself doesn't require a building permit.

Windstorm Requirements on the Texas Coast

Texas homeowners in the 14 coastal counties — Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Refugio, San Patricio, and Willacy — plus parts of Harris County east of Highway 146 face an additional layer of requirements through the Texas Department of Insurance Windstorm Inspection Program.

To qualify for windstorm and hail insurance through the Texas Windstorm Insurance Association (TWIA), structures must be certified as meeting windstorm building code requirements. This means a shed in Galveston or Corpus Christi that might be exempt from a local building permit may still need a WPI-8 Certificate of Compliance from TDI to be covered under a windstorm insurance policy.

The windstorm inspection process requires construction to be inspected at multiple stages — foundation, framing, roof decking, and final — by a TDI-appointed inspector or a Texas-licensed professional engineer. As of September 2020, all new construction in the designated catastrophe area must comply with the structural provisions of the 2018 IRC.

This is a practical concern for coastal Texas homeowners. A shed that gets destroyed in a hurricane is a loss, but a shed that gets destroyed and takes part of your house with it — because it wasn't anchored to withstand high winds — is a much bigger problem. If you live in a coastal county, check with your insurance agent and TDI before building.

HOA Restrictions

Texas has one of the highest rates of Homeowners Association (HOA)-governed properties in the country, particularly in the rapidly growing suburbs around Houston, Dallas–Fort Worth, San Antonio, and Austin. HOA rules about sheds are often stricter than city building codes.

Common HOA restrictions on sheds include limits on size, height, materials, colors, roof style (many require the shed's roof to match the house), and placement. Some HOAs prohibit sheds entirely or limit them to certain types — for example, allowing only manufacturer-built sheds but not site-built ones, or requiring that sheds be screened from street view by landscaping.

Unlike fencing, where Texas state law (Property Code Section 202.023) limits HOA authority to restrict perimeter fences, there is no equivalent state law protecting a homeowner's right to build a shed. Your HOA can prohibit or severely restrict sheds within the bounds of the community's deed restrictions.

Always check with your HOA's architectural review committee before building or purchasing a shed. Get approval in writing. Building first and asking forgiveness later can result in fines, liens, and orders to remove the structure.

Consequences of Skipping the Permit

If your city requires a permit and you build without one, the consequences escalate:

• Stop-work orders if the shed is caught during construction
• Daily fines that accumulate until the violation is resolved — Fort Worth fines can reach $500 per day for general violations and up to $2,000 per day for safety-related issues
• Retroactive permit applications — some cities allow you to apply after the fact, but fees are typically higher
• Removal orders — in the worst case, the city can require you to tear the shed down
• Sale complications — an unpermitted structure can delay or derail a home sale when buyers, title companies, or lenders flag the violation

The financial math almost always favors getting the permit. San Antonio's shed permit is $150. Even in cities where fees are based on project value, a typical shed permit runs $50–$200. Compare that to the cost of demolishing and rebuilding, plus any fines accumulated in the meantime.

If you're also planning a garage or carport alongside your shed, note that Texas has separate permit requirements for each structure. Planning your projects together can simplify the application process, especially since zoning rules often limit the total number and combined square footage of accessory structures on a single lot.
