Do you need a permit to remodel a home in Scottsdale?

In most cases, yes. The City of Scottsdale's home improvement page says you need a permit for remodels and additions and for any project that involves structural changes or adding or moving electrical, plumbing or mechanical systems. It lists cosmetic work like interior painting, flooring, cabinets and countertops as work that doesn't need one. So a kitchen with new cabinets and countertops is a different job from a kitchen where a wall comes out or the sink moves.

This is general information, not legal or building advice. The City of Scottsdale decides what your project needs, and a licensed Arizona attorney can tell you how the law applies to you. I read the sources below on November 5, 2026, and the city updates its pages, so check the current ones before you start work.

The city's home improvement page says a permit is needed for projects that involve construction, structural changes, demolition, or adding or moving electrical, plumbing or mechanical systems. Its examples are swimming pools and spas, walls and fences, patio covers and patio or garage enclosures, carports, ramadas and accessory buildings, guest homes, sewer repair, remodels and additions, and changes to the outside of a building.

The city's permit services page says the same thing from the permit side. Building permits are required for all construction work, including additions, patio covers and carport enclosures. Electrical permits are required to install, alter or repair wiring, and mechanical permits cover furnace and air conditioning work other than portable or window units. Plumbing permits cover plumbing, gas, lawn sprinkler supply and water heater replacement.

According to the city's home improvement page, you don't need a permit for cosmetic work that doesn't involve structural changes or skilled trades. The page's examples are interior doors and hardware, carpet, flooring and trim, cabinets and countertops, drywall, paneling and stucco (insulated stucco systems do need a permit), interior painting, re-roofing with the same roofing material, and repairing or replacing existing landscape irrigation piping.

A few small projects fall in between. The same page says the city does a courtesy review, with no permit, of detached structures under 200 square feet that have no water, gas, sewer or electrical connections, walls three feet or less (not retaining walls), patio slabs and sidewalks not over 30 inches above grade, fire pits and barbecues, and exterior painting in Environmentally Sensitive Lands and Historic Property districts. The city still checks code, design and setbacks on those. I cover the hillside rules in my post on hillside lots and the ESL ordinance.

The city's 2022 amendments to the 2021 International Building Code back up two items on that list. Section 105.2 says a permit isn't required for a one-story detached shed, playhouse or similar structure with a floor area not greater than 200 square feet, or for a fence not over 3 feet high, and it says an exemption doesn't authorize work that breaks the code or any other law or ordinance of the city. The city page says under 200 square feet and the code says not greater than 200, so if your project is close to that size, ask the city before you build.

The city's permit services page says permits are typically issued after plan review, and that some smaller home improvement projects don't need it. For most single-family electrical, mechanical and plumbing work, the city issues a minimum permit with no plan review. The page says you can get one online, and an inspection confirms the installation afterward. The home improvement page gives examples: replacing an air conditioner like for like in the same location, adding or replacing windows and doors (except replacing glass in an existing frame), a new ceiling fan, an electrical service upgrade up to 400 amps, a water heater replacement, a sewer line repair, and gas lines for exterior appliances.

According to the home improvement page, everything else that needs a permit starts with plan review. The permit services page adds that some projects need only an administrative plan review, and it points to a submittal packet for minor single-story remodels under 1,000 square feet. The city does its inspections in phases, and once a project passes final inspection it issues a certificate of occupancy or a final acceptance letter, according to the home improvement page.

The city's permit services page and its home improvement page both say work completed without a permit is fined an amount equal to double the permit fee. The city's building code amendments say the same in Section 109.4: anyone who starts work on a building, structure, or electrical, gas, mechanical or plumbing system before getting the necessary permits pays a fee double what the permit would have cost, and emergency work is exempt from the penalty if a permit is obtained at the beginning of the next business day.

The city pages don't say what unpermitted work means when a house is sold, so I can't tell you that here.

The Arizona Department of Real Estate's Buyer Advisory says the seller may have made repairs or added a room, that you should feel comfortable the work was done properly or have an expert evaluate it, and that you should ask for copies of permits, invoices or other documentation about the work. It lists permit search sites for Phoenix and Tucson and says to search the Planning and Development site for other cities.

An added room, a garage turned into living space and an enclosed patio are all work to ask about, because the city lists remodels, additions and patio and garage enclosures as work that needs a permit. Ask for the permits and the invoices for each one, ask the seller to write down what was done and when, and then compare what you're told with the seller's disclosure statement and with what your inspector sees. I explain the inspection period and how repair requests work in my post on the inspection period in Arizona.

If you're selling, pull together the permits and invoices for work done to the house, including any paperwork that came with it when you bought. The Buyer Advisory says a seller's disclosure obligation remains even if the buyer and seller agree that no seller's property disclosure statement will be provided, so what you know about the work is something to put in writing. Here's my post on seller disclosure in Arizona.

Arizona's contractor licensing statute, A.R.S. 32-1121, exempts work of a casual or minor nature with a contract price under $1,000, but not when the work requires a local building permit, and the Department of Real Estate's Buyer Advisory says the same. The Advisory also says an unlicensed owner may do work on a property intended for the owner's own occupancy. If the property is listed or offered for sale or rent within one year of the completed work, that is prima facie evidence the owner did the work for purposes of sale or rent, and the statute uses the same one-year test for owners who build or improve their property.

If you might list the house within a year of finishing the work, ask the Arizona Registrar of Contractors or an Arizona attorney how those rules apply to you before you start, and check the current statute for the dollar figure.

The city's home improvement page says to check with your homeowners association before you start, because the city doesn't enforce CC&Rs. The Department of Real Estate's Buyer Advisory says CC&Rs generally let an association control certain aspects of how a property is used, and that associations often have architectural control standards. So the city's permit and the association's rules are two separate checks. Here's my post on HOA rules and regulations in Arizona.

Look up each part of the project on the city's home improvement page, apply for a minimum permit or start plan review for anything on the permit list, and read your association's rules before you hire anyone. Keep the permits, the final inspection paperwork and the invoices together in one folder, since the Buyer Advisory tells buyers to ask for them.
