Landscaping permits and code in Tucson

Updated July 2026

Routine planting is not the permit trap in Tucson. Structural elements, walls, grading, and anything touching the water supply are, and which office you deal with depends on whether your address is inside Tucson city limits or in unincorporated Pima County, two separate authorities with separate processes.

When landscaping typically needs a permit

Everyday planting, mulch, gravel, decomposed granite, and small garden beds generally do not require a permit in Tucson. Work that more often does cross into permit territory includes retaining and garden walls, fences and walls that exceed the code's height standards for perimeter yards, in-ground pools, grading tied to drainage, and irrigation work connected to the potable water system. Tucson's Unified Development Code sets specific height and setback standards for walls and retaining walls, but those standards vary by location and are not a substitute for a permit determination, so confirm the current limits and whether a permit applies for your project and address with the authority below before assuming either way.

Who is the local authority: city or county

For a property inside Tucson city limits, the City of Tucson Planning and Development Services Department (PDSD) is the Authority Having Jurisdiction. For a property in unincorporated Pima County, which covers much of the surrounding metro, Pima County Development Services handles permitting instead, through its own online Permit Gateway. These are two different offices with two different processes, so confirm which one covers your address before you assume either applies; a landscaper who works across the metro should already know.

Tucson and Pima County native plant rules

A genuinely local wrinkle: Tucson and Pima County both have native plant preservation ordinances that protect certain species, including saguaro and ironwood, primarily on development and land-clearing projects. Separately, Arizona state law requires a permit, tag, and seal from the Arizona Department of Agriculture before anyone moves or salvages a saguaro cactus over 4 feet tall from its original growing location, a rule that applies even to a homeowner clearing a lot, not just commercial developers. If your project involves removing or relocating a large saguaro, check this before work starts.

What happens if you skip a required permit

Unpermitted structural landscaping (a wall, a major grading change, a pool) can complicate a future home sale, may not be covered by homeowners insurance if it causes damage, and skips the inspection that confirms the work meets current safety and drainage code. A licensed contractor who normally pulls permits as part of the job is one of the things you are paying for.
