Douglas, Arizona Building Permit Guide

Inside the City of Douglas, building permits are issued by Development Services on the second floor of City Hall, 425 E. 10th Street. Fees are set in the Douglas Municipal Code: a new home is valued at $52 per square foot, the permit fee comes from a valuation table and plan review adds 65%. The City says most residential permits are processed in 5 to 10 business days.

What requires a building permit in Douglas?

The City’s construction FAQs say a permit is required for most construction, electrical, plumbing and mechanical work, on homes and on commercial property alike.

The City treats every structure intended for business or for multi-family housing as commercial construction. Fence height is limited to 3 ft in the front yard and the first 25 ft of a side yard measured from the front property line, and 6 ft in the back and side yards.

Who issues building permits in Douglas?

Development Services handles building permits and plan review, planning and zoning, and code enforcement for the City. Its Building Safety office checks that buildings and structures comply with the adopted codes and City ordinances, and applications are routed from there to Planning, Public Works, the Fire Department and the Police Department as the project requires.

City permits cover land inside the Douglas city limits. Cochise County has its own Building Safety Division, which reviews plans, issues permits and inspects under the Cochise County Building Safety Code, so establish which side of the city boundary the parcel is on before choosing an application.

Douglas permit applications

Douglas uses two bilingual application forms, both dated July 2024.

• Residential Building Permit Application: used for all single-family, multi-family and mobile home projects, including stand-alone electrical, plumbing and mechanical permits. The permit types on the form are new construction, addition, remodel, garage, carport, accessory building, deck or covered porch or ramada, mechanical-electrical, plumbing-gas, swimming pool or hot tub, re-roof, fence or wall, and accessory dwelling unit.
• Commercial Building Permit Application: used for commercial site and building development and for mechanical or utility service projects.

Every application includes the Contractor Affidavit. A licensed contractor enters the Registrar of Contractors licence number, licence class and City business licence number; an owner claiming an exemption signs as owner-builder and resident occupant, or as an owner-developer working with listed licensed contractors.

The City’s 2025 construction FAQs say you can apply through the City of Douglas Development Services Portal, with help available at City Hall or by phone. Questions go to permits@douglasaz.gov.

Douglas building permit fees

Douglas writes its fees into Section 15.08.010 of the Municipal Code, last amended in March 2025. The code first sets a valuation per square foot, then a schedule of building permit review and inspection fees based on that valuation. The per-square-foot figures are valuations, not fees.

Plan review is 65% of the building permit review and inspection fee. The filing fee is charged up front when plans are received and is not refundable. For example, a new 1,500 sq ft home is valued at $78,000, so the permit fee is $803.35 plus the $20 filing fee, and plan review is about $522.

Other fixed charges in the code: $125 for work begun without a permit, $25 for a residential and $50 for a commercial certificate of occupancy, $35 for a driveway inspection, and $50 per hour for re-inspections and for inspections outside normal business hours (2-hour minimum after hours).

Electrical, plumbing, mechanical and solar permits in Douglas

Trade permits come from the same Development Services office and are requested on the residential or commercial application, where you count the fixtures, outlets and equipment being added or relocated. The Municipal Code sets flat fees for these inspections.

Mechanical equipment and gas piping that is not listed on the application is left off the permit, and a separate permit and fees are then needed. The application asks whether the building is sprinklered throughout and is routed to the Fire Department where fire review applies.

Documents to submit with a Douglas application

The July 2024 application forms end with a checklist. All plans must be complete and legible and must mark each item as existing or proposed.

Both forms ask whether the site is in a FEMA-designated floodplain. If it is, include a flood elevation certificate or flood insurance policy; a state-registered civil engineer or surveyor must document flood elevations for existing and proposed structures for the City Engineer’s review. Accessory dwelling unit plans need a site plan, a code data sheet and the architectural, structural and trade plans that apply.

Review times vary with scope. The City’s current FAQs give 5 to 10 business days for most residential permits and 2 to 3 weeks for most commercial permits when the submittal is complete and needs no revisions.

How to apply in Douglas: 6 steps

Douglas inspections, expiry and certificates of occupancy

Schedule inspections by calling 520-417-7329 or emailing permits@douglasaz.gov. Inspections are required at key stages through the project, and work has to be inspected before it is covered or concealed. Have the site address, permit number and project scope ready when you call.

A permit expires if no work or inspection takes place within 180 days. The City’s Development Services FAQ adds that permits for a new dwelling or new commercial space run for 18 months, and that a permit can be extended once, on written request.

A certificate of occupancy is issued in one of three ways: after the final inspection on a tenant improvement permit, through a change-of-use permit, or on completion of new construction. Records of earlier permits for an address are obtained with a public records request.

Local Douglas details that matter

Older code editions: the Municipal Code still adopts the 2006 International Building, Residential, Plumbing, Mechanical, Fuel Gas, Existing Building and Energy Conservation Codes and the 2005 National Electrical Code. Development Services has posted a notice that it is reviewing the IBC and IRC for possible adoption of updated standards and is taking comments at permits@douglasaz.gov, so check the edition in force before finalizing drawings.

Tiny houses: in July 2024 the City adopted Appendix Q of the 2021 International Residential Code, with local amendments that tie it back to the 2006 IRC.

Accessory dwelling units: ADUs are allowed on lots with single-family homes and in mixed-use zones. They need 5 ft side and rear setbacks and 5 ft of separation from the main home, require no extra parking, must have water, sewer and electric service, and cannot be sold separately. RVs, manufactured homes and tiny homes on wheels do not count as ADUs.

Lot splits: get City approval before recording a split with the county. A parcel split without it cannot be developed.

Overlay districts: the applications let the owner of a site in an overlay zoning district choose to adopt that overlay’s regulations.

Who may do the work: an owner may work on a home they occupy. If the home is rented, or sold or rented within one year of completion, the City expects a licensed contractor for anything beyond cosmetic work.

Arizona licenses contractors through the state Registrar of Contractors, and the small-job exemption never covers work that needs a permit. Arizona rules
