Codes adopted
Arizona has no statewide building code for non-state buildings; codes are adopted locally. According to the International Code Council, codes are adopted locally in Arizona and are predominantly the I-codes, with different cities and counties choosing their own editions and local amendments. The Arizona State Fire Code (adopting the 2018 IFC) applies only to state and county buildings, public and private schools, and non-residential occupancies in areas without a locally adopted fire code — it does not establish a statewide residential or commercial building code floor. Each city and county adopts its own code editions independently, resulting in different I-Code years and amendment sets across jurisdictions. There is no state-mandated minimum edition; enforcement is entirely local. Always confirm the adopted edition and any local amendments with the specific jurisdiction before submitting plans.
Permit types & fees
Residential Building Permit (New Construction)
Required for construction of new single-family homes, duplexes, and other one- and two-family dwellings in Tucson. Reviewed against the 2024 International Residential Code (IRC) and 2024 IECC (effective 7/1/2026) as adopted and amended by the City of Tucson. Applications are submitted through Tucson Development Center (TDC) Online, PDSD's self-service permitting portal.
Residential Addition / Alteration Permit
Required for additions, remodels, and structural alterations to existing one- and two-family dwellings in Tucson, including porches, garages, room additions, and interior remodels affecting structural or life-safety elements. Reviewed against the 2024 IRC as adopted by the City of Tucson. Fee is based on a percentage of standard valuation depending on alteration level (per the International Existing Building Code).
Electrical Permit (Trade Permit)
Required for hardwired electrical installation, alteration, or repair work in Tucson, governed by the 2023 National Electrical Code (NEC) as adopted by the City of Tucson (effective 1/1/2026). Issued as a Trade Permit under the FY27 fee schedule, priced per item rather than by valuation.
Plumbing Permit (Trade Permit)
Required for plumbing installation, alteration, or repair work in Tucson, governed by the 2024 International Plumbing Code (IPC) as adopted by the City of Tucson (effective 1/1/2026). Issued as a Trade Permit, priced per item rather than by valuation.
Mechanical / HVAC Permit (Trade Permit)
Required for heating, ventilation, and air conditioning installations in Tucson, governed by the 2024 International Mechanical Code (IMC) and International Fuel Gas Code (IFGC) as adopted by the City of Tucson (effective 1/1/2026). Issued as a Trade Permit, priced per item.
Roofing Permit (Structural Roof Work)
Required for structural roof work and new roof installations in Tucson; routine like-for-like roof-surface repair/replacement is generally exempt unless the property is in a Historic Preservation Zone or Neighborhood Preservation Zone. Governed by the 2024 IRC/IBC as adopted by the City of Tucson.
Residential Solar Photovoltaic (PV) Permit
Required for installation of rooftop solar photovoltaic systems in Tucson. Licensed solar contractors can use SolarApp+ for eligible residential projects for same-day (24-hour) automated review; ineligible projects use the standard 20-business-day Tucson Development Center Online review. Governed by the 2023 NEC (Article 705 interconnection) as adopted by the City of Tucson.
Demolition Permit
Required for interior and/or exterior demolition of any building, structure, or exterior wall in Tucson, including removal of unpermitted structures and swimming pool demolition. Fee is based on square footage of area demolished. Falls under the Fast Lane (10-business-day) review track.
Fence and Wall Permit
All fences and walls in Tucson require a permit for zoning review of location, height, and distance from structures, regardless of height. Engineered structural plans are required for taller fences/walls or any wall functioning as a retaining wall. Fee is based on wall type, surface area, and linear footage. Falls under the Fast Lane (10-business-day) review track.
Accessory Dwelling Unit (Casita) Permit
Accessory Dwelling Units (ADUs), locally called 'casitas,' are allowed by right in Tucson, one per residential lot. The permit includes zoning, building, and utility review and must meet applicable Accessory Dwelling Unit standards for both attached and detached units.

Tips & gotchas
- Arizona has NO statewide mandatory building code — every Arizona city and county adopts its own codes independently. Tucson adopts ICC/NFPA model codes on a six-year cycle with local amendments under Ordinance #12171; the current cycle is the 2024 International Codes (effective 1/1/2026) plus 2024 IECC (effective 7/1/2026) and 2023 NEC (effective 1/1/2026).
- Tucson/Pima County use the International Plumbing Code (IPC), not the Uniform Plumbing Code (UPC) used by some neighboring Mountain West jurisdictions.
- PDSD's Permit Review Lanes replaced an earlier same-day/15-day/30-day framework with more granular targets: Express Lane (24 hours: commercial/residential trade, electrical reconnect, SolarApp+), Fast Lane (10 business days: fences, ADUs/casitas, demolition, pools, manufactured homes, new dwellings from a model template), Standard Lane (20 business days: additions/alterations, new commercial buildings, non-SolarApp+ solar, zoning/floodplain items), and Complex Lane (variable, dedicated project manager: entitlements, special districts, historic).
- Review-timeline clocks start when staff initializes a submittal, which can itself take up to 3 business days except for same-day (Express Lane) permits.
- Trade Permits (electrical, plumbing, mechanical) are priced per item, not by project valuation: $150 for the first item (covers up to 1/2 hour review + 2 inspections) plus $50 for each additional item on the same application.
- All fences and walls require a zoning-review permit in Tucson regardless of height — there is no minimum-height exemption. Engineered structural plans are additionally required only once a fence/wall exceeds 6 feet or functions as a retaining wall.
- ADUs ('casitas') are allowed by right in Tucson (up to two per lot with a single-family Family Dwelling, one with a duplex, a third on lots over 1 acre with a deed-restricted affordable unit) and are processed in the Fast Lane; per Tucson UDC Section 6.6.3.B, a casita may be sized up to 75% of the primary home's floor area (max 1,000 sq ft) or up to 650 sq ft regardless of primary home size, with a 5-foot side/rear setback and the zone's single-family height limit (commonly 25 feet).
- SolarApp+ delivers same-day (24-hour) residential solar permits for eligible roof-mounted systems; ineligible projects (Historic/Neighborhood Preservation Zone, ballasted systems, additions to existing PV) fall back to the 20-business-day standard review.
- Most residential inspections (not just solar) can be completed via Remote Video Inspection using a smartphone; most commercial work still requires an in-person inspector, though follow-up corrections may sometimes use Remote Video Inspection.
- Rental single-family homes are treated as COMMERCIAL property for permitting purposes and require a licensed contractor — the Owner/Builder exemption under A.R.S. Section 32-1121.A only applies to owner-occupied homes, and never applies once permit-required work exceeds $1,000 in materials/labor.
- Arizona's 'Beat the Heat' rule lets construction start as early as 5 a.m. on weekdays between May 1 and October 15 to protect workers from extreme heat.
- PDSD's FY27 fee schedule was adopted by Mayor and Council on May 19, 2026 and took effect July 1, 2026 — verify current fees against the live Fee Schedule page since fees typically roll forward each fiscal year.
- PDSD publicly warns that phishing emails impersonate official PDSD correspondence; legitimate permit invoices come exclusively from noreply@eplmail.tylerapp.com, and PDSD never requests payment or wire transfers by email.
- A Certificate of Occupancy (CofO) is required for newly constructed, relocated, remodeled, or altered buildings, or for a change in use/occupancy classification; a Letter of Completion (LofC) is issued instead when a CofO is not required (e.g., replacing mechanical equipment that doesn't affect an existing CofO). All CofO/TCO/LofC requests are made through Tucson Development Center Online using the active permit number.
- No dedicated statewide or city-published 'Design Criteria' page analogous to cold-climate jurisdictions' snow-load/frost-depth pages was found for Tucson — Tucson's desert climate has no frost-depth or snow-load design values comparable to Mountain West cities like Billings, MT; structural design values are governed directly by the adopted 2024 IBC/IRC and ASCE 7 references incorporated by those codes.
