Do You Need an Excavation Permit in Phoenix?
By North Valley Rock Team • Published May 28, 2026
One of the most common questions we get is, "Do I really need a permit just to move dirt?" In the City of Phoenix and surrounding municipalities, the answer is almost always yes, depending on the volume of dirt and the scope of the project.
When Permits Are Required
Generally, you must obtain a grading and drainage permit if you are:
- Moving more than 50 cubic yards of earth
- Altering the existing drainage pattern of the property
- Digging a new swimming pool
- Excavating for a new foundation or retaining wall over 3 feet tall
Blue Stake / Arizona 811
Separate from city permits, it is legally mandated to contact Arizona 811 before any digging occurs. This free service marks all underground utility lines (gas, water, power) to prevent catastrophic accidents. As part of our standard process, we handle this coordination for you.
The Danger of Unpermitted Work
Skipping the permit phase to save a few dollars is a massive risk. Unpermitted changes to drainage that flood your neighbor's yard can result in severe civil liability. Furthermore, unpermitted structures can prevent you from selling your home later.
