Commercial Building Permit (New Construction, Alterations, Tenant Improvements) in South Tucson, Arizona

Required for new construction, alterations, modifications, or tenant improvements to commercial properties/structures in South Tucson. Administered entirely by the City of South Tucson's own Planning, Zoning and Development Services Department (NOT contracted to the City of Tucson or Pima County, despite South Tucson being geographically enclosed by Tucson -- confirmed by live fetch of the City's Development Services pages 2026-08-01). Reviewed against the 2018 IBC and related 2018-cycle codes (2017 NEC) as adopted and amended under Ordinance No. 25-01. Tenant improvements are NOT a separate permit type -- the City's Permits page lists 'new construction, alterations, modifications, or tenant improvements to commercial properties/structures' as one combined category under the same permit process, with no TI-specific application, fee line, or timeline published anywhere on the City's site. Applications are submitted through the City's Online Permit Portal (live since March 2, 2026), in person, or by mail to City Hall.

Fee schedule

Commercial Building Permit Fee (valuation-based)CONFIRMED GAP, re-chased 2026-08-01: the live Permits page (fetched with full browser headers, 200 OK) states only 'Permit cost is dependent on the valuation of proposed permit activity' with no linked numeric table, identical to the finding documented in this file's residential-building-permit entry. The City's own adopted-code amendment deletes the ICC model valuation-fee table (IBC Section 109.3 deleted in its entirety per ST 2018 IBC AMENDMENTS) and defers to fee schedules 'adopted by the jurisdiction by separate ordinance' whose numeric content is not posted online (Ordinance 15-01 and 25-01 are scanned, non-text-extractable PDFs; the Municode City Code Chapter 4 page is an empty JS shell). A fresh 2026-08-01 WebSearch for a South Tucson building-permit fee schedule (including anything newly published alongside the March 2026 Online Permit Portal) surfaced nothing beyond the same pages. Per the Inspections page, the standard permit fee covers a fixed number of inspections; extra charges apply for ungrouped partial inspections, custom field inspections, and reinspections (no amounts published for any of these either). Confirm the current valuation-based fee directly with Development Services at 520-792-2424 or via the Online Permit Portal, which calculates cost at application time.
Not published -- fee is calculated based on the valuation of the proposed permit activity (cost of labor and materials); no commercial-specific or TI-specific fee line exists

Tips

  • Tenant improvements are NOT a distinct permit type in South Tucson: the City's Permits page (fetched live 2026-08-01) groups 'new construction, alterations, modifications, or tenant improvements to commercial properties/structures' into one category under the same general permit process, and no TI-specific application form, fee line, or review timeline is published anywhere on the City's site. A separate commercial-tenant-improvement-permit entry is therefore deliberately NOT included for this jurisdiction.
  • The Certificate of Occupancy rules are where TI distinctions actually matter here: a new CofO is required for a TI of a newly occupied space, a TI changing square footage, or a TI changing occupancy type/classification or requiring a greater degree of safety -- but NOT for minor improvements like flooring or paint with no layout/square-footage/occupancy/accessibility/egress change, and NOT for a new tenant occupying a space with the same use as the previous tenant's existing CofO (the certificate attaches to the space and use, not the business name).
  • Every commercial job -- including modest TIs -- needs plans drawn by an Arizona Board of Technical Registration registrant in the applicable discipline AND a licensed contractor; both the design professional and the contractor must also carry an active City of South Tucson business license ($40/year plus quarterly occupational fees, per the City's Finance pages). Budget for this dual-licensing requirement, which is stricter than state-license-only jurisdictions. Contractor
  • CONFIRMED GAP -- fees and review timeline: South Tucson publishes neither a numeric valuation-based commercial fee table nor an A.R.S. Section 9-835 review-timeframe document; both gaps were re-chased and re-confirmed 2026-08-01 (live page fetches plus fresh WebSearch, including checking whether the March 2026 Online Permit Portal launch brought a published fee schedule with it -- it did not). Call Development Services at 520-792-2424 or email submittals@southtucsonaz.gov for a case-specific fee quote and review-time estimate.
  • Despite being fully surrounded by the City of Tucson, South Tucson reviews and inspects its own commercial projects through its own Development Services Division -- do not submit to Tucson PDSD or Pima County. The one county touchpoint in a standard commercial flow is Pima County Health Department approval for food-related businesses (a pre-CofO requirement).
  • South Tucson's adopted codes (2018 IBC/2017 NEC per Ordinance No. 25-01) are a full ICC cycle behind neighboring Tucson and Pima County (2024 codes/2023 NEC) -- design teams working across jurisdictional lines should not assume code parity across the boundary.
  • Inspections run only Mondays and Wednesdays, 7:00-9:00 a.m., requests due the business day before; the standard permit fee covers a fixed number of inspections, so group partial inspections (e.g., temporary power with underground water/sewer) to avoid extra-inspection charges, and note custom field inspections carry extra charges.

No. The City's Permits page treats new construction, alterations, modifications, and tenant improvements to commercial properties as one category under the same building-permit process, with no TI-specific application, fee, or timeline published. What changes for a TI is the Certificate of Occupancy: a new CofO is required if the TI is in a newly occupied space, changes square footage, or changes the occupancy type/classification (or requires a greater degree of safety), while minor flooring/paint work and same-use tenant turnover need no new CofO.

Neither. South Tucson is a separately incorporated city with its own Planning, Zoning and Development Services Department that independently reviews plans, issues permits, and conducts inspections for commercial projects within its roughly one-square-mile limits. Pima County's only routine role in a commercial project is Health Department approval for food-related businesses before a Certificate of Occupancy.
