Do I need a permit for a carport in Arlington, TX?

In nearly all cases, yes. The City of Arlington treats a carport as a structure, and erecting a new structure requires a building permit. This applies whether the carport is attached to your house or freestanding.

You apply through the City's online permitting portal (Accela, reached through arlingtonpermits.com), where you can upload your plans and a site plan, schedule inspections, and track the status. Plan to show the carport's size, height, materials, and exact placement on the lot.

There is a narrow exemption people sometimes hear about. Arlington exempts a one-story detached accessory structure of about 100 square feet or less, with no utilities, from a building permit. The model residential code many Texas cities reference (the 2021 IRC) sets that line at 200 square feet, but Arlington uses a lower local threshold, so do not assume the larger number. Either way, a carport is almost never that small once it covers a vehicle, and the exemption never waives zoning, setback, easement, or placement rules. Treat a carport as needing a permit unless the City tells you otherwise in writing.

Not by right. Arlington's Unified Development Code lets a carport be built in front of the home's building face or within the required front yard setback only on lots with single-family detached homes in the R, R1, R2, and D residential districts, and only with a special exception granted by the Zoning Board of Adjustment.

Duplexes and other single-family attached homes are not eligible for that front-yard special exception at all. The code also describes a carport as an open-sided structure, supported by poles or posts, with no walls, used for temporary parking of no more than two operable vehicles, trailers, or RVs, and not for storage of any kind.

A detached carport in the back or side yard is usually the simpler path. It still needs a permit and still has to meet the setback and height limits for accessory structures, but it does not require the front-yard special exception.

Carports and other accessory structures must meet the dimensional standards for your zoning district, which Arlington sets out in its Unified Development Code. Setbacks depend on the lot, the district, and the street, so the exact numbers for your property come from the City.

As a sense of how detailed the code gets, Arlington's accessory-structure standards include reduced setbacks for smaller, lower structures, for example easing a larger required setback from a rear line that backs an arterial or collector street when the structure stays under a set wall height and floor area. Side and rear yard requirements, lot coverage limits, and height caps all vary by district, so treat any single figure as an illustration and verify your lot's numbers with Planning and Development Services.

Because Arlington sits in the DFW area, also build for Texas weather. Size the posts and anchoring for North Texas wind and storms, and choose a finish that holds up to intense sun and heat. Hot-dip galvanizing or a quality powder coat over properly prepped steel resists rust and UV fading far longer than a thin painted prefab panel.

Inside Arlington city limits, the City handles permitting and zoning. If your property is in unincorporated Tarrant County instead, the county does not enforce zoning the way a city does and often does not permit small accessory structures, but extraterritorial jurisdiction (ETJ), floodplain, or development standards can still apply, so verify which jurisdiction you are in first.

A homeowners association is separate from the City. If you are in an HOA, it can have its own rules on whether a carport is allowed, how it must look, and where it can sit, and HOA approval does not replace a City permit. Check your deed restrictions and get written HOA approval before you start.

Prices vary widely. A basic prefab metal carport in the Dallas-Fort Worth area often starts around $2,000 for a small single-car unit and climbs to roughly $8,000 to $12,000 or more for a large double or triple with a vertical roof and heavier-gauge steel. These are general market estimates, not a CJM price.

A custom, welded steel carport built and installed by hand typically costs more than a bolt-together prefab kit, because it uses heavier material, a real foundation, and craftsmanship meant to last. Final cost depends on size, steel gauge, roof style, finish, site prep, and ground conditions. Permit fees, which the City sets and can change, are separate.
