The one-sentence answer
In Maricopa and Pinal County you need a building permit when a bathroom remodel changes the plumbing piping, adds or extends electrical circuits, touches structure (walls, headers, the slab) or alters a window. You do not need one to replace fixtures and finishes in the same spot: tile, vanity, faucet, toilet, mirror, lighting on an existing circuit, paint. Every city in the Valley draws the line in roughly the same place because they all adopt the International Residential Code with local amendments.
The gray zone is the tub-to-shower conversion. A tub uses a 1½-inch drain; a shower requires 2 inches. If the drain is upsized or moved, that is a plumbing change and most cities want a permit. If you keep the tub drain location and a licensed plumber confirms it meets the shower requirement (rare in older homes), some jurisdictions treat it as a fixture replacement. We pull the permit on every conversion where the drain changes, and we tell you which case you are in at the consultation.
What needs a permit and what does not
| Work | Permit? | Why |
|---|---|---|
| New vanity, faucet, toilet, mirror, paint, tile floor or walls in place | No | Like-for-like fixture and finish replacement |
| Replacing a shower valve in the same location | Usually no | Fixture replacement; check if the city counts valve bodies |
| Tub-to-shower conversion with drain upsized or moved | Yes (plumbing) | Drain size and trap change; inspected before the pan is covered |
| Curbless shower with a recessed slab | Yes | Slab cut; drain relocation; post-tension slabs need engineering |
| Moving the toilet, sink or shower to a new wall | Yes (plumbing) | New supply and drain routing |
| Adding a circuit, heated floor, new exhaust fan run or GFCI outlets | Yes (electrical) | New wiring; fan must vent to outside, not the attic |
| Removing or moving a wall, enlarging a doorway, adding a window | Yes (building) | Structure and egress; may need engineer's letter |
| Replacing an exhaust fan with a like model on the existing duct and circuit | No | Appliance swap |
A full remodel almost always includes at least one permitted item, so budget for a combination permit that covers plumbing, electrical and building under one number. A refresh (vanity, tile, paint) almost never does.
City by city: who issues it, what it costs, how long it takes
Fees below are typical for a residential bathroom remodel with plumbing and electrical, drawn from each jurisdiction's published schedules. They are revised most years and some depend on declared job value, so treat them as a planning range and let your contractor quote the exact number. Turnaround assumes no structural work.
| Where you live | Who issues the permit | Typical fee | Turnaround |
|---|---|---|---|
| Phoenix (incl. Arcadia, Biltmore, Ahwatukee, Desert Ridge, Laveen, Moon Valley) | City of Phoenix Planning & Development, online through SHAPE PHX | $250–$700 | Same day to about a week for a simple remodel |
| Scottsdale | City of Scottsdale One Stop Shop | $300–$800 | 1–2 weeks; more if a slab cut needs engineering |
| Paradise Valley | Town of Paradise Valley Building Safety | $300–$900 | 1–3 weeks; strict on plan detail and site rules |
| Gilbert | Town of Gilbert Development Services | $200–$600 | Often over the counter for trade-only work |
| Chandler | City of Chandler Building Safety | $200–$600 | A few days to 2 weeks |
| Mesa | City of Mesa Development Services | $200–$600 | A few days; express permits for trade work |
| Tempe | City of Tempe Community Development | $200–$650 | About a week |
| Glendale, Peoria, Surprise, Goodyear, Avondale, Buckeye, Litchfield Park | Each city's Building Safety or Development Services | $150–$600 | Same day to about 2 weeks |
| Queen Creek | Town of Queen Creek Development Services (parts of town are in Pinal County) | $200–$600 | About a week |
| Cave Creek, Carefree, Fountain Hills | Town building departments | $200–$700 | 1–2 weeks; small staffs, plan ahead |
| Sun City, Sun City West, Anthem, other unincorporated areas | Maricopa County Planning & Development (these are not inside a city) | $200–$600 | About 1–2 weeks |
| Apache Junction | City of Apache Junction Development Services | $150–$500 | About a week |
| City of Maricopa | City of Maricopa Development Services | $150–$500 | About a week |
| San Tan Valley, Gold Canyon, other unincorporated Pinal | Pinal County Community Development | $150–$550 | 1–2 weeks |
Two things surprise homeowners. Sun City and Sun City West are not cities; the permit comes from Maricopa County. And San Tan Valley is unincorporated, so a home with a Queen Creek mailing address may permit through Pinal County instead of the town.
How the inspections actually go
For a typical permitted shower or full bath remodel there are three to four inspection visits, and they line up with the build so a well-run job loses at most a day to scheduling.
- Rough plumbing. After demo, the new drain, trap and supply lines are in but nothing is covered. The inspector checks pipe size, slope and venting. On a slab cut, the trench is open and the patch happens after sign-off.
- Rough electrical (if wiring changed). New circuits, GFCI protection, the fan run to the exterior and any heated-floor wiring are visible before drywall or backer board goes up.
- Shower pan or waterproofing. Many Valley cities want to see the pan flood-tested, or the membrane installed with the drain, before tile. Even where the city does not require it, we flood-test for 24 hours because the cost of a failed pan is the whole shower.
- Final. Fixtures set, valve tested, fan running, outlets protected, glass in. The permit is closed and the record stays on the property.
Inspections are usually scheduled a day or two out through the city's online portal, and the inspector gives a morning or afternoon window. Your contractor should be on site to meet them. If an inspection fails, the correction is noted, fixed and re-inspected; on a bathroom that is rarely more than a day.
HOAs, 55+ communities and what they can and cannot require
An HOA does not issue building permits and cannot waive them. What it controls is the outside of the house and the way work happens on the property. In most Valley subdivisions an interior bathroom remodel needs no HOA approval at all. Where you do hear from the association:
- Exterior changes. A new or enlarged window, a new exhaust vent through a wall instead of the roof, or a skylight usually needs architectural review and a matching color or trim.
- Work rules. Gated communities such as DC Ranch, Anthem Country Club, Encanterra, Trilogy and PebbleCreek issue contractor gate passes, set work hours (often 7am–5pm weekdays), restrict dumpster or trailer placement and require the contractor's insurance certificate on file. Plan a week for the paperwork.
- Sun City and Sun City West. There is no traditional HOA; deed restrictions are enforced by the Recreation Centers and the county handles permits. Sun City Grand in Surprise and Sun Lakes in Chandler do have community associations with contractor registration and hour limits.
- Condos and townhomes. If the drain or supply runs through a shared wall or ceiling, the association usually wants notice and sometimes its own plumber's sign-off. Water damage to a neighbor below is the reason.
Ask your contractor for the insurance certificate and ROC license number on day one; every association that asks for them asks for exactly those two documents.
What happens at resale if the work was never permitted
This is where the shortcut gets expensive. Arizona's Seller's Property Disclosure Statement asks directly whether any additions or alterations were made and whether permits were obtained. You answer under penalty of the buyer's later claim, so unpermitted work must be disclosed. From there:
- Buyers negotiate. An inspector who sees a new shower with no permit on file writes it up, and buyers ask for a credit, a retroactive permit or both. Ten thousand dollars of remodel becomes a bargaining chip against you.
- Retroactive permits cost more. Cities will issue an as-built permit, but the fee is commonly doubled, and the inspector needs to see what is behind the tile. On a shower that means opening a wall or the pan. Sometimes it means redoing the waterproofing.
- Lenders and appraisers. FHA and VA appraisers in particular flag unpermitted plumbing and electrical, and a lender can condition the loan on correction.
- Insurance. If an unpermitted drain leaks and floods the hall, the adjuster asks the same question the buyer would. Carriers do deny water claims tied to unlicensed, unpermitted plumbing.
Against that, the permit for a shower remodel costs a few hundred dollars and adds a day or two of scheduling. It is the cheapest insurance in the whole project, and a fixed-price contractor should simply include it.
Will a permit raise my property taxes?
Rarely for an interior bathroom remodel. Maricopa and Pinal County assessors value homes primarily by market comparison, and an interior remodel adds no square footage and changes no property class. An addition or casita is a different story. What a permitted remodel does do is show up in the property record, which helps at sale.
The honest summary: replace finishes freely, permit anything that moves water, wiring or structure, let the licensed contractor pull it, and keep the closed permit with your house papers. Our fixed price includes the fee, the scheduling and the inspector visits wherever a permit applies. A full remodel with plumbing and electrical typically runs $18,500 to $60,000 with permits in the number; a tub-to-shower conversion runs $7,900 to $16,500, permit included when the drain changes.
Questions people ask
Do I need a permit to replace a bathtub with a shower in Phoenix?
If the drain is upsized to 2 inches or moved, yes, a plumbing permit. If the drain and valve stay exactly where they are and already meet code, it can be treated as a fixture replacement. We check and pull the permit when it applies; it is included in the fixed price.
How much does a bathroom remodel permit cost in Maricopa County?
Most Valley cities charge $150–$800 for a residential bathroom permit covering plumbing and electrical, depending on the city and declared job value. Unincorporated areas like Sun City go through Maricopa County at a similar range.
How long does the permit take?
Trade-only permits are often issued the same day or within a week. Structural work or a slab cut on a post-tension slab can take 1–3 weeks because an engineer’s letter is reviewed. We pull the permit before demo so it never holds up the schedule.
Can I pull the permit myself to save money?
Arizona allows owner-builder permits, but you then become responsible for code compliance and lose the ROC protections you get from hiring a licensed contractor. The fee is the same either way. Let the licensed contractor pull it.
Does my HOA need to approve an interior bathroom remodel?
Usually no. HOAs control exterior changes and work rules such as gate passes, hours and dumpster placement. Gated and 55+ communities often require the contractor to register with insurance and license on file before the first day.
