Tucson ADU Permit Fees & Cost Calculator
Tucson allows ADUs on residential lots, but the official sources found here describe the zoning rules more clearly than the fee schedule. I found a city PDF showing fee examples and fee-per-square-foot figures, but not a current official fee schedule for ADU-specific permit, impact, or utility charges, so most fee entries must remain unverified.

Fee overview
I did not find a current official Tucson ADU fee schedule in the provided results, so exact permit, impact, and utility fees remain unconfirmed.
The strongest official sources found here address zoning and dimensional rules, not fees.
Non-official sources mention fee ranges, but they should be verified against Tucson Planning & Development Services and Tucson Water before being used in a project budget.
The request is for permit and pre-development fees tied to a residential ADU in the City of Tucson, not Pima County unincorporated area or nearby South Tucson.
Because the search results did not surface a current official Tucson fee schedule, fee amounts are left null unless directly supported.
The city's ADU code and fee structure may have changed after the cited city PDF, so current verification is needed before use.
FAQs
Are Tucson ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Tucson?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Arizona?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
