Permit application form — Include property owner name and contact info, property address and parcel/tax ID number, contractor name and license number (if using a contractor), project description (e.g., 'New 24x24 detached two-car garage with electrical'), and estimated construction cost including materials and labor.
Site plan (plot plan) — Must show property boundary lines with dimensions, all existing structures on the lot, the proposed garage location with dimensions, distances from the garage to all property lines (to verify setback compliance), easements, utility locations, driveway and access, a north arrow, and scale. Include total lot coverage calculations (existing plus proposed impervious area).
Foundation plan — Show footing dimensions and depth (must reach below the local frost line), slab thickness and reinforcement, anchor bolt spacing and placement (typically 1/2-inch bolts at 6 feet on center per IRC R403.1.6), vapor barrier under slab, and any plumbing or conduit that must be placed before the pour.
Construction / framing drawings — Plan view showing wall layout, door and window locations, and all dimensions. Elevation views showing overall height, roof pitch, and exterior materials. Section views showing wall framing (stud size and spacing), roof framing (rafter or truss size and spacing), header sizes over garage door and window openings, and sheathing details. For attached garages, show the connection to the existing house structure.
Fire separation details (attached garages) — Required for any garage that shares a wall, ceiling, or roof structure with the house (IRC R302.6). Must show: 1/2-inch gypsum board on garage side of common walls, 5/8-inch Type X gypsum board on garage side of the ceiling if living space is above (IRC R302.6, Table R302.6), self-closing door between garage and house (rated 20 minutes minimum), and no openings between garage and sleeping rooms.

Additional documents when applicable — Engineering calculations for unusual spans or heavy loads, truss manufacturer specifications, HOA approval letter, historic district review approval, flood zone elevation certificate, or a property survey if setbacks are tight.

Requirements may vary. Contact Development Services Department for the complete list of required documents.

Common Mistakes to Avoid in Fort Worth

Not checking setback requirements before designing

Every property has setback lines — minimum distances structures must be from property lines. Detached garages typically must be 3–5 feet from side property lines and 5–10 feet from rear lines, but this varies by jurisdiction. In many cities, detached garages in rear yards have reduced setbacks compared to the house — but you must verify. Building over a setback line violates zoning and may require demolition. Check your local zoning map or call the building department before you design.

Ignoring lot coverage limits

Most zoning codes limit the total footprint of all structures (house, garage, shed, etc.) to a maximum percentage of the lot area — commonly 40–60%. A new garage can push you over the limit, especially on smaller lots. Calculate your total lot coverage before designing. If you're close to the maximum, you may need to reduce the garage size or apply for a variance, which adds months and cost.

Inadequate fire separation for attached garages

This is one of the most critical safety requirements and a common inspection failure. IRC R302.6 requires: 1/2-inch gypsum board on the garage side of all common walls between the garage and the house, 5/8-inch Type X gypsum board on the garage ceiling if habitable rooms are above, a self-closing door (not self-latching — self-closing, meaning it closes by itself) between the garage and house rated at 20 minutes minimum, and no openings between the garage and sleeping rooms. Inspectors check this carefully. Fire separation protects your family from car fires and carbon monoxide intrusion.

Converting a garage without permits

This is one of the most common unpermitted projects in the US — and one of the riskiest. An unpermitted conversion will be flagged at resale by home inspectors and appraisers, the added square footage cannot be counted in your home's assessed value, your homeowner's insurance may deny claims, and the building department can require you to restore the garage to its original condition. Conversions also have specific code requirements for habitable space (insulation, egress, ceiling height, ventilation) that protect occupant safety.

Not meeting habitable-space codes for conversions

A garage-to-living-space conversion must meet all habitable room standards: minimum 7-foot ceiling height (IRC R305.1), at least one egress window per bedroom (minimum 5.7 sq ft clear opening, IRC R310.2.1), insulation meeting local energy code, adequate heating and cooling, proper ventilation, and GFCI-protected outlets. Many garages have low ceilings, no insulation, and inadequate electrical — all of which must be upgraded.

Forgetting parking replacement requirements

Many zoning codes require a minimum number of off-street parking spaces per dwelling unit — typically 1–2 spaces. Converting your garage eliminates those spaces, and your zoning department may require you to replace them with a new driveway pad, carport, or other off-street parking. Check this before you apply — some jurisdictions will deny the conversion if parking cannot be replaced.

Undersized headers over garage door openings

A standard two-car garage door opening is 16 feet wide — that requires a substantial structural header to carry the load above. Using undersized lumber or improper header construction is a common DIY mistake and a guaranteed inspection failure. Header sizing depends on the span, load from above (roof, second story), and species of lumber. Consult IRC Table R602.7(1) or have an engineer specify the header.

Starting construction before getting the permit

Building departments can issue stop-work orders, fines (often 2–10x the original permit fee), and in serious cases, demolition orders. An after-the-fact permit — if the department even allows one — comes with penalty fees and may require tearing out finished work so inspectors can verify hidden construction.

Required Inspections in Fort Worth

Most garage / carport projects in Fort Worth require inspections at each construction stage:

Foundation / Slab Inspection

When: After forms are set and any required reinforcement is in place, but before concrete is poured

Footing dimensions match approved plans, depth is below the local frost line, soil conditions are adequate (no loose fill or organic material), reinforcement (rebar or wire mesh) is positioned correctly, anchor bolt locations and spacing meet code (IRC R403.1.6), vapor barrier is installed under the slab, and any plumbing or electrical conduit is in place before the pour.

Common failures: Footings not deep enough (must reach below frost line), missing or misplaced anchor bolts, no vapor barrier under slab, loose soil at the bottom of footings.

Framing Inspection

When: After all structural framing is complete but before insulation, drywall, or exterior cladding covers the framing — the inspector must be able to see all framing members

Wall stud sizes and spacing match plans, headers over garage door and window openings are properly sized and supported (jack studs, king studs, cripples), top plates and bottom plates are properly fastened, roof framing (rafters or trusses) matches approved plans, sheathing and nailing patterns meet code, and bracing and tie-downs are installed where required. For attached garages, the connection to the existing house structure is inspected.

Common failures: Undersized headers for garage door spans, missing or incorrect hurricane ties/straps on roof framing, wrong nailing schedule for sheathing, improper stud spacing.

Electrical Inspection

When: After all wiring is roughed in but before walls are closed up — the inspector must see all wires, boxes, and connections

Wire sizes match circuit breaker ratings, GFCI protection on all garage outlets (NEC 210.8(A)(2)), at least one lighting outlet is provided (IRC E3903), proper box fill calculations, wire secured and protected where required, and subpanel or new circuits are properly connected. For EV charger circuits, dedicated circuit capacity and wire sizing are verified.

Common failures: Missing GFCI protection on garage outlets, wire not properly secured to framing, overfilled junction boxes, wrong wire gauge for the circuit amperage.

Fire Separation Inspection (attached garages)

When: After drywall is installed on the garage side of common walls and ceiling, but typically before taping and mudding

Correct drywall thickness on garage side of common walls (1/2-inch minimum), 5/8-inch Type X on ceiling if habitable space is above, all joints and penetrations properly sealed, self-closing door installed between garage and house, door is rated for 20 minutes minimum, and no openings exist between the garage and sleeping rooms (IRC R302.6).

Common failures: Wrong drywall thickness (standard 1/2-inch instead of 5/8-inch Type X on ceiling), unsealed penetrations around pipes or wires through fire-rated assemblies, door not self-closing or not properly rated.

Final Inspection

When: After all work is complete — exterior finish, garage door installed, electrical finished, driveway approach (if required)

Overall project matches approved plans, garage door operates properly, all electrical is complete and functional, fire separation is intact and complete, exterior finish matches plans, grading and drainage direct water away from the foundation, driveway approach meets city standards (if applicable), and address numbers are posted and visible.

Common failures: Grading that directs water toward the foundation instead of away, incomplete fire separation, electrical cover plates not installed, project deviates from approved plans.

Schedule inspections with Development Services Department at (817) 392-2222 at least 24–48 hours in advance.

Pro Tips for Garage / Carport Permits in Fort Worth

For attached garages, understand IRC R302.6 fire separation requirements before you start — this is the most inspected and most failed aspect of attached garage construction. You need 1/2-inch drywall on all common walls (garage side), 5/8-inch Type X on ceilings below living space, and a self-closing door rated at 20 minutes minimum. Get this right the first time.
Detached garages typically have reduced setback requirements compared to the main house — in many jurisdictions, a detached garage can be as close as 3 feet to the side or rear property line. But this varies significantly by city. Call your building department to get the exact setbacks for your specific zoning district and property.
If you're building a detached garage, consider whether you want to pre-wire for electricity even if you don't need it now. Running conduit during construction costs a fraction of what it costs to trench and add electrical after the slab is poured and walls are finished.
For garage conversions, check the ceiling height before spending money on plans. Garages are typically built with 8-foot walls, but the slab may be 4–6 inches below the house floor level, and ceiling joists or ductwork can reduce clearance. IRC R305.1 requires a minimum 7-foot ceiling height for habitable rooms — if your garage doesn't meet this, the conversion becomes significantly more expensive or may not be feasible.
Get a property survey if you have any uncertainty about where your property lines are. A $300–$500 survey is far cheaper than discovering that your new garage violates a setback after it's built.
Calculate your total lot coverage before designing. Add the footprint of every structure on your lot (house, existing garage, sheds, covered porches) and divide by your total lot area. If you're near the maximum, your new garage or expansion may not be permitted without a variance.
For garage-to-living-space conversions, contact your zoning department separately from the building department. Zoning handles the change of use and parking requirements; the building department handles construction code compliance. You may need approvals from both, and zoning review can take longer.
Ask your building department about prescriptive garage plans. Some departments publish standard garage designs that are pre-approved for structural adequacy. Using a prescriptive plan can dramatically speed up plan review because the reviewer only needs to verify site-specific details like setbacks and lot coverage.
If hiring a contractor, verify they will pull the permit in their name. A legitimate contractor pulls permits as a matter of course. If a contractor suggests skipping the permit or asks you to pull it yourself, that's a red flag about their licensing and insurance.
Budget for the permit as part of your project cost. A $500–$2,500 permit fee for new garage construction is a small fraction of a $15,000–$60,000 build, and it protects your investment, your safety, and your home's resale value.
