Do I Need a Permit for a Bathroom Remodel in McKinney, TX?
Bathroom remodels in McKinney sit at the intersection of Texas's relatively permit-friendly home improvement culture and the practical reality that plumbing and electrical work always require permits — even in the Lone Star State. McKinney draws the line clearly: cosmetic updates with no plumbing moves, no electrical changes, and no wall work are permit-free; the moment you touch the plumbing rough-in, modify circuits, or open walls, you need trade permits. McKinney's flat-fee trade permit structure ($40 each for electrical and mechanical; $25 minimum for plumbing) keeps the permit costs on bathroom remodels low compared to valuation-based systems in California.
McKinney bathroom remodel permit rules — the basics
McKinney's permit system for home improvements separates building, plumbing, mechanical, and electrical permits into independent tracks with their own flat fees. For a bathroom remodel, the relevant permits are: a plumbing permit when any plumbing fixture is relocated or a new one is added; an electrical permit when new circuits, outlets, or exhaust fan wiring is installed or modified; and a building/structural permit when walls are removed or modified. Each of these permits is independently applied for through McKinney's Citizen Self-Service (CSS) portal at mckinneytexas.org/css and inspected by the appropriate Building Inspections inspector.
The purely cosmetic bathroom remodel — replacing tile floors and walls, swapping a vanity for another in the same location with the same plumbing rough-in, replacing a toilet in the same position, repainting, replacing a light fixture in the same electrical box — does not require any permit in McKinney. This is the same general rule as in most jurisdictions: decorative finishes and like-for-like fixture replacements without changing the rough-in don't trigger permit requirements. The key test is whether anything that is concealed (behind the wall, under the floor, or in the ceiling) is being changed or moved.
McKinney adopted the 2024 International Residential Code on October 1, 2025 — the most current edition nationally. For bathrooms, the 2024 IRC brings updated ventilation requirements: all bathrooms must have mechanical exhaust ventilation (exhaust fan or operable window) sized for the bathroom's volume. Installing a new exhaust fan where none existed, or upgrading a fan as part of a remodel, involves electrical wiring and requires an electrical permit. GFCI protection is required for all bathroom receptacles per both the IRC and the 2024 National Electrical Code — any new outlet installation or circuit modification in a bathroom must include GFCI protection.
McKinney's master-planned community HOAs generally don't have visibility into interior bathroom remodels unless the remodel affects the exterior (e.g., a new exhaust fan vent on the exterior wall or a new window). For interior-only bathroom remodels, HOA approval is not typically required — unlike deck or fence projects where HOA review is standard. This is one area where McKinney's HOA structure doesn't add a layer of complexity beyond the city permit requirements.
Three McKinney bathroom remodel scenarios
| Bathroom Remodel Scope | Permits Required in McKinney |
|---|---|
| New tile, new vanity same location, new toilet same position — no plumbing moves | No permit — cosmetic update with no change to rough-in. Licensed plumber for fixture connections still recommended (Texas plumber licensing requirements). |
| Relocating toilet, shower, tub, or sink (new drain/supply rough-in location) | Plumbing permit required ($25 min + $2.50/fixture). Licensed Texas plumber required to pull permit. |
| New electrical outlets, new exhaust fan wiring, new circuits | Electrical permit required ($40 flat). Licensed Texas electrician required. GFCI required for all bathroom receptacles per 2024 IRC/NEC. |
| Removing or moving walls | Building permit required (Residential Alteration) — $0.68/sq ft affected + $100 plan review. Structural check required; engineer if load-bearing. |
| New exhaust fan (new box + wiring) | Electrical permit required ($40). Vent duct through exterior also requires building permit if penetrating exterior wall. |
Texas contractor licensing and McKinney bathroom remodels
Texas law requires licensed contractors for plumbing and electrical work — and this applies regardless of whether a permit is required. A licensed Texas master plumber (TSBPE license) must pull plumbing permits in McKinney; a licensed Texas electrician (TDLR Master Electrician or Journeyman under supervision) must pull electrical permits. General contractors doing framing and tile work don't have a state license requirement in Texas for residential work, but McKinney requires contractors to register with the city's Development Services department. Homeowners can pull their own permits for work on their own primary residences in Texas, but plumbing and electrical work must still be inspected to verify code compliance.
Many McKinney homeowners hire a general contractor who then subcontracts the plumbing and electrical work to licensed subs who pull their own trade permits. This is the most common workflow for a full bathroom remodel in McKinney. When vetting contractors, verify: licensed Texas plumber (search at tsbpe.texas.gov), licensed Texas electrician (search at tdlr.texas.gov), and contractor registration with McKinney Development Services.
What bathroom remodels cost in McKinney
McKinney's North Texas location places bathroom remodel costs in a mid-tier market — significantly less expensive than Bay Area California but modestly higher than the national average due to the region's hot construction market. A cosmetic hall bathroom refresh (no rough-in changes): $8,000–$18,000. A standard master bath remodel with tub-to-shower conversion: $20,000–$40,000. A full master bath gut and expansion: $35,000–$65,000. Permit fees are modest: $40–$250 for most bathroom remodel scopes. Texas's deregulated electricity market (Oncor distribution, retail choice) means no utility pre-approval needed for bathroom electrical work — just the McKinney permit.

Common questions about McKinney bathroom remodel permits
Do I need a permit to remodel my bathroom in McKinney?
It depends on the scope. Purely cosmetic work — new tile, new fixtures in same locations, no plumbing moves, no electrical changes — requires no permit. Plumbing work (moving fixtures) requires a plumbing permit ($25 min + $2.50/fixture). Electrical work (new circuits, outlets, exhaust fans) requires an electrical permit ($40 flat). Wall removal requires a building permit ($100 plan review + $0.68/sq ft). Apply via CSS at mckinneytexas.org/css or call 469-617-4800.
Does converting a tub to a walk-in shower need a permit in McKinney?
Yes — a tub-to-shower conversion typically involves relocating the drain (plumbing rough-in change = plumbing permit) and adding shower lighting (electrical permit). The plumbing permit costs $25 minimum plus $2.50 per relocated or added fixture. The electrical permit is a flat $40. Both must be pulled by licensed Texas contractors (licensed plumber for plumbing, licensed electrician for electrical). Total permit cost is typically under $100 for a standard walk-in shower conversion.
What is the fee for a plumbing permit in McKinney?
The minimum plumbing permit fee in McKinney is $25. Each individual fixture (toilet, sink, shower, bathtub, drain, disposal, etc.) adds $2.50. For a bathroom remodel with 3 fixtures involved: $25 + $7.50 = $32.50 total. These fees are significantly lower than California's valuation-based permit systems — a $35,000 bathroom remodel in Fremont generates $1,500+ in permit fees; the same scope in McKinney generates $25–$150 in trade permit fees.
Does McKinney require GFCI in bathrooms?
Yes. The 2024 International Residential Code (adopted by McKinney October 1, 2025) and the 2024 National Electrical Code both require GFCI protection for all receptacles in bathrooms. Any new outlet installation or circuit modification in a McKinney bathroom must include GFCI protection. The electrical inspector verifies GFCI installation during the inspection. Replacing an existing non-GFCI outlet with a GFCI outlet is generally treated as maintenance and may not require a permit, but installing new receptacles requires the electrical permit.
Do I need HOA approval for a bathroom remodel in McKinney?
Generally no for interior-only bathroom remodels. McKinney's HOAs govern exterior changes visible from the street or neighboring properties. Interior bathroom remodels typically don't require HOA ARC approval unless the project involves exterior changes — like adding or moving an exhaust vent on the exterior wall, or adding a window. If your remodel scope touches the exterior, confirm HOA requirements with your community's ARC before starting work.
Can a homeowner pull their own bathroom remodel permits in McKinney?
Homeowners can pull permits for work on their own primary residences in Texas. However, Texas law requires licensed plumbers (TSBPE) for most plumbing work and licensed electricians (TDLR) for electrical work — these licensed professionals must do the actual work even if the homeowner pulls the permit. For structural/building permits, general contractors in Texas don't require a state license for residential work, but must be registered with McKinney's Development Services. Contact Building Inspections at 469-617-4800 to confirm specific requirements for your scope.
