Residential Permits


A permit and inspections are required for most residential projects, including porches, additions, and equipment such as air conditioners and water heaters. If new work is performed, such as replacement of gas piping, a plan may be necessary to obtain the permit.

It is the homeowner/property owner’s responsibility to provide plans and obtain a permit for:

  • All new residential buildings
  • Electrical reconnections, service increases, panel replacement or repair
  • Gas line pressure tests (new or replacement lines)
  • Water heater installation (including replacements)
  • Furnaces, Heat Pumps, Air Conditioners (new or replacement) & Evaporative Coolers (new only) NOTE: Load and sizing calculations are required for new AND replacement HVAC equipment
  • All residential walls or fences must have a site plan review for Zoning Compliance. Additionally, walls and fences over 7 feet tall require a building permit with a structurally engineered design
  • Detached accessory structures over 200 square feet (e.g. Storage Sheds)
  • Porches, additions or garages
  • Remodeling of existing structures

Planning and Development Services can review construction plans submitted by the customer, but we cannot design the plans for you. If you need help in designing a plan, you will need to contact a design professional. All plans are required to be neat, legible, and well organized. 

Rental units are considered commercial property, and all commercial permits require a licensed contractor.

When you submit your plans, different staff will review them to determine compliance with building codes, zoning codes, floodplain regulations, fire safety, and other requirements. Be sure to review applicable codes as you design your project. 

You may obtain a permit for work that has already occurred. However, the same requirements will apply to include a full set of construction drawings and completed inspections. A permit authorizes work to be done so if the project has already begun, please discontinue work until you obtain your permit.

Reconnect Permits

A permit is required to reconnect electric or gas service to a residence. This is sometimes referred to as "jurisdictional clearance" by utility companies. Reconnect permits are required if the utility has been shut off to a residential structure for 6 consecutive months. The permit cost is $135.59 which covers administrative and inspection costs. If you are installing water or gas piping, a drawing must be submitted that identifies the size and length of all piping. Include the Gas Piping Template(PDF, 308KB) with your application.

We inspect for any obvious code violations relating to the utility being connected or other life safety hazards are addressed prior to approving release of electrical power or gas to the premises.

We recommend that you review the Electrical Reconnect Guidelines(PDF, 102KB) and pre-inspect the dwelling prior to your inspection. New equipment is not considered a reconnect and will be charged according to the proposed work.

If you require a reconnect for a duplex or similar multi-structure dwelling, any building with independently metered units, building number and/or unit number is required for utility confirmation and approval. Please confirm your address(es) with Pima County Addressing before applying for a reconnect.


Owner/Builder Affidavit

In lieu of hiring a general contractor, A.R.S.§ 32-1121.A. provides guidance for residential home owners to assume responsibility for the projects on their homes and be exempt from the State of Arizona contractors’ license laws. Homeowners who wish to use the exemption must be listed as the owner on the permit, complete the Owner/Builder Affidavit form(PDF, 158KB), and submit the form during the application process using Tucson Development Center Online.
