Frisco, Texas Building Permit Cost Calculator

Frisco splits building permit pricing by occupancy. Residential new construction is priced by square footage in banded tiers: a base amount covers the first block of square footage and an incremental per-square-foot rate applies above it, with the incremental rate decreasing as the house gets larger. Commercial building permits instead use a construction-valuation table, and Frisco charges 60% of that table value. Plan review is billed hourly rather than as a percentage of the permit fee, including reviews of plan revisions. Failed inspections trigger a re-inspection fee that differs between commercial and residential work. Schedule shown as updated 10-7-2025.

Decks are priced as a hybrid: a flat base charge plus a per-square-foot rate applied to gross area or any fraction of it, and the total is capped so that a very large deck cannot exceed a stated ceiling. This is the same formula Frisco applies to conventionally framed accessory structures. Plan review, if required, is billed separately at an hourly rate, and a failed inspection adds a residential re-inspection fee.

Frisco charges electrical work two ways at once. There is a flat issuance fee for each electrical permit, and then a per-gross-square-foot charge on the building area served, at a lower rate for residential than for commercial. Frisco does not use the old per-outlet or per-fixture unit fee model for electrical. Failed inspections add the residential or commercial re-inspection fee, and any plan review time is billed hourly. Schedule shown as updated 10-7-2025.

The fence permit is a single flat fee with no linear-foot, height or material component, so a short side-yard run and a full perimeter fence pay the same amount. Frisco does not publish a separate plan review charge for fences; review time, if any, would be billed at the schedule's hourly plan review rate, and a failed inspection adds the residential re-inspection fee. Schedule shown as updated 10-7-2025.

Re-roofing is a single flat permit fee in Frisco with no square-footage, valuation or material multiplier, so the same amount applies regardless of roof size. Roof replacement using the same material is one of the categories Frisco has moved to instant self-service issuance, so in practice there is no plan review charge; a failed inspection would add the residential re-inspection fee. Schedule shown as updated 10-7-2025.

Retaining walls are charged a flat fee assessed per wall rather than by length, height or valuation, so a project with multiple separate walls pays the fee multiple times. Structural review of an engineered wall would be billed at the schedule's hourly plan review rate on top of the permit, and a failed inspection adds the applicable re-inspection fee. Schedule shown as updated 10-7-2025.

Accessory structures (sheds), whether conventionally framed on site or modular, use the same flat-base-plus-per-square-foot formula Frisco applies to decks, with the same maximum cap. Gross area is used and any fraction of a square foot rounds up. Because the base is charged regardless of size, even a small shed pays a meaningful minimum; the cap keeps large detached structures from scaling indefinitely. Any required plan review is billed hourly on top. CORRECTION 2026-09-10: the per-square-foot formula applies to a CONVENTIONALLY FRAMED shed only. The Frisco schedule lists "Modular Shed" as a separate line at a flat $50.00, so a modular/prefabricated shed is not priced on the $75 + $0.59/SQFT basis.

Frisco prices water heaters as a plumbing unit fee rather than a standalone flat permit. The schedule charges a small per-unit amount for each water heater and/or vent, which is the same per-unit amount charged for a plumbing fixture on one trap. In practice a water heater changeout permit is the plumbing permit issuance charge plus that per-unit fee, so the out-the-door cost depends on how the issuance fee is applied to a self-service permit. Failed inspections add the residential re-inspection fee. Schedule shown as updated 10-7-2025.
