Short answer: in the City of Houston, a one-story detached shed of 120 sq ft or less, a wood or chain-link fence up to 8 feet, and a detached deck of 200 sq ft or less that is no more than 30 inches high and doesn't serve the exit door don't need a building permit. Masonry fences, attached or covered decks, larger sheds, and all electrical, plumbing, and mechanical work do. Deed restrictions can still be stricter.
Houston is famous for having no traditional zoning.
That leads a lot of homeowners to assume they can build anything in the back yard. In reality, Houston still enforces building codes, still requires permits for most construction, and many neighborhoods are governed by deed restrictions that can be stricter than any zoning code.
This guide covers the common Houston building permit questions for decks, sheds, and fences, based on the Houston Permitting Center's own guidance. Always confirm current rules for your address. See our disclaimer.
Houston shed, fence, and deck exemptions in one table

Houston starts from "everything needs a permit"
Houston's guidance is direct: "Any alteration, repair, remodel, renovation, or new construction in both residential and commercial buildings requires permits unless specifically exempted." The exemptions include painting, carpet, tile, flooring, and small exterior wood repairs under 128 square feet. Everything else starts from the assumption that a permit is needed.
Houston sheds: 120 square feet
Houston exempts "one-story detached accessory structures, provided that the floor area does not exceed 120 square feet." That is smaller than the 200-square-foot limit many other Texas cities use, so a 10x12 shed (exactly 120 square feet) is right at the limit. If your shed will have electrical power, the wiring needs an electrical permit and a licensed electrician even if the shed itself is exempt. See our general shed permit guide.
Houston wood and chain-link fences up to 8 feet
Typical wood or cyclone (chain-link) fences up to 8 feet tall that are not electrically energized do not need a building permit. Houston's fencing page adds that "fences constructed completely or partially of masonry or concrete require a permit regardless of height above grade," and fences of any material over 8 feet also need a permit. Deed restrictions often set lower heights or require specific materials, so check those before you build. See our fence permit guide for corner-lot and sight-line issues.
Houston decks: 200 square feet, 30 inches, detached
"Decks not exceeding 200 square feet in area, that are not more than 30 inches above grade at any point, are not attached to a dwelling and do not serve the exit door" are exempt. Covered decks, attached decks or roof structures, decks over 200 square feet, and decks higher than 30 inches need a permit. Adding a roof turns it into a patio cover question; see pergola and patio cover permits and our deck permit guide.
Fine print from Houston's September 2025 permit package
The Houston Permitting Center's Permit Information Package for Common Residential Projects (revised September 2025) spells out the exemptions in more detail than the short Top 10 handout:
- Sheds: one-story detached accessory structures are exempt if the floor area "does not exceed 120 square feet." Under that wording, a 10x12 shed at exactly 120 square feet fits. The older Top 10 handout says "less than 120," so if you're right at the line, confirm with the One-Stop desk before you buy.
- Decks: the exemption only covers decks up to 200 square feet that are no more than 30 inches above grade at any point, aren't attached to the house, and don't serve the required exit door. An attached deck, or one bigger than 200 square feet, needs a permit even if it's low.
- Retaining walls: exempt up to 4 feet, measured from the bottom of the footing to the top of the wall, unless the wall holds back a surcharge. See retaining wall permits.
- Storage buildings and garages over 120 square feet: plan on a Texas registered survey or a complete site plan showing property lines, easements, and building setback lines. Lots under 15,000 square feet that go over 65% impervious cover, and all lots over 15,000 square feet, also go to the Storm Section for review.
How to apply in Houston
Applications go through iPermits, and plans are uploaded electronically. A few things the One-Stop guide asks for tend to catch homeowners off guard:
- A signed owner declaration that gets checked against HCAD records. If the names don't match, you'll need to upload proof of ownership.
- Plans drawn to scale with dimensions. Drawings on graph paper, photos, and 3D renderings aren't accepted.
- Approval from the Flood Plain Section for any project on a lot in the floodplain.
The package also warns that permits can be revoked for deed restriction violations, so check those before you pay. Houston has a building permit fee calculator if you want an estimate first. Adding a driveway with a new curb cut? Only a bonded contractor can buy that permit in Houston; see driveway curb cut permits.
Deed restrictions: Houston's real zoning
Because Houston lacks conventional zoning, deed restrictions do much of the work: setbacks, fence heights, lot coverage, and even what can be built in a back yard. The city's guidance tells property owners to verify whether restrictions exist before building, and points to the Harris County Clerk for records. HOAs and civic clubs may enforce them. A city permit does not override a deed restriction. See HOA approval vs city permits.
Licensed trades and inspections
Mechanical, electrical, and plumbing work must be permitted and performed by licensed professionals, with a limited homeowner plumbing permit for owner-occupied homestead properties (see plumbing and gas permits). Houston says construction inspection requests are completed the next business day, which makes it one of the faster inspection systems among large cities.
Floodplain reminder
Large parts of Houston lie in mapped floodplains. Projects in a floodplain can need extra review, elevation certificates, and may trigger the 50% substantial improvement rule for larger remodels. See flood zone remodel permits.
Houston address, but outside city limits?
A Houston mailing address doesn't always mean the City of Houston issues your permit. If you're in unincorporated Harris County, the County Engineer's office handles it, and its rule is broad: "A permit is needed for all development within Harris County" (Harris County Office of the County Engineer). Its residential application covers accessory structures, garages, carports, driveways, pools, and fill, and you apply online through E-Permits (Harris County residential permits).
Two county differences worth knowing: a residential fence outside the special flood hazard area doesn't need a county permit, but any driveway built in the county right-of-way does, including one that crosses a roadside ditch. If you live in one of the smaller cities inside Harris County, call that city's building department instead.

Houston fences and sheds near the street: sidewalk and right-of-way rules
Most back-yard work in Houston stops at the property line. Work at the front of the lot can reach the public side, and the city has separate rules there. Under the city’s sidewalk rules in Chapter 40 (Sec. 40-553), a new fence, shed, or deck is not one of the permits that trigger a sidewalk review. A new sidewalk is, and so is repairing or replacing more than 20 feet of sidewalk. A new single-family house triggers it too, while interior remodeling or an expansion of the existing house does not. If a front-fence project also replaces the walk along the street, measure the run.
When a sidewalk is required and the block has none, the owner can build it or, if the project meets Sec. 40-560(b)(1), pay a fee in lieu. A deed restriction that bans sidewalks does not settle the question. Sec. 40-553 does, because most sidewalks sit in the public right-of-way. A tree or power pole in the way does not excuse the sidewalk either. It has to route around the obstruction unless the city approves a modification or a fee in lieu.
The Permitting Center’s permit package adds that no fill may be placed in a public right-of-way. Driveway, sidewalk, curb, and culvert work uses its own application, Form 1023, with a Texas registered survey or a complete site plan. Only a bonded contractor can buy that permit, though a homeowner can buy it when no curb cut is involved.
Houston shed, fence, and deck questions
Do I need a permit for a shed in Houston?
Not if it is a one-story detached shed of 120 square feet or less, according to the Houston Permitting Center. Larger sheds need a permit, and wiring always needs an electrical permit.
Do I need a permit for a fence in Houston?
Not for typical wood or chain-link fences up to 8 feet. Masonry or concrete fences need a permit at any height. Check deed restrictions too.
Does Houston have zoning?
Not traditional use-based zoning, but building codes, some development rules, and private deed restrictions still apply.
Do I need a permit for a deck in Houston?
Only small, detached decks are exempt. Under the September 2025 permit package, that means 200 square feet or less, no more than 30 inches above grade at any point, not attached to the house, and not serving the required exit door. Anything else, including covered decks, needs a permit.
Do I need a permit for a retaining wall in Houston?
Not up to 4 feet, measured from the bottom of the footing to the top of the wall, unless it holds back a surcharge, according to the Houston Permitting Center's September 2025 permit package.
Can I build a shed or fence that breaks my deed restrictions if the city approves it?
No. A city permit doesn't override a deed restriction, and the permit package warns permits can be revoked for deed restriction violations. Check the restrictions with the Harris County Clerk's records first.
Before you build in Houston
Houston's exemptions are specific: sheds of 120 square feet or less, wood or chain-link fences up to 8 feet, and detached decks of 200 square feet or less, up to 30 inches high, that don't serve an exit door. Everything else, including all trade work, generally needs a permit, and deed restrictions can add their own limits. Confirm with the Houston Permitting Center before you build.
Next steps for a Houston project: run the 10-minute AHJ permit checklist, and read shed permit requirements by size and HOA approval vs a city permit for the deed-restriction side. Compare with our Dallas and Austin guides.
