Whether you’re adding a room, building an ADU, or starting a commercial project, getting a building permit in Phoenix is a required step — and skipping it can cost you far more than the permit itself. Unpermitted work can stall a home sale, trigger fines, or require you to tear out completed construction.
The good news: the Phoenix permit process is straightforward once you know what to expect. Here’s exactly how it works.
Do You Need a Building Permit in Phoenix?
Most construction projects in Phoenix require a permit. This includes:
- New home construction
- Room additions and remodels
- Accessory Dwelling Units (ADUs)
- Garage conversions
- Structural changes
- Electrical, plumbing, or mechanical work
- Pools and spas
- Fences over 6 feet tall
Minor work like painting, flooring, or cabinet replacements generally does not require a permit. If you’re unsure, the City of Phoenix Development Services Department can tell you whether your specific project requires one.
Step 1: Prepare Your Project Plans
Before you can apply for a permit, you need permit-ready construction documents. These are detailed architectural drawings that show exactly what you’re building — floor plans, elevations, structural details, and site information.
Your drawings must meet the International Building Code (IBC) or International Residential Code (IRC), depending on your project type, as well as Phoenix’s local amendments.
This is where most projects either move quickly or get stuck. Incomplete or non-compliant drawings are the number one reason permits get rejected or delayed. Working with an experienced architectural drafting firm ensures your plans are formatted correctly and code-compliant before they ever hit the city’s desk.
Step 2: Determine Your Permit Type
Phoenix uses several permit categories depending on the scope of work:
- Building permit — for structural work, new construction, and additions
- Residential permit — for single-family homes and ADUs
- Commercial permit — for tenant improvements, new commercial buildings, and change of use
- Trade permits — separate permits for electrical, plumbing, and mechanical work
Your architectural drawings will determine which permit types apply to your project.
Step 3: Submit Your Application
Phoenix offers two ways to submit:
Online (ProjectDox) — The City of Phoenix uses an electronic plan review system called ProjectDox. You upload your drawings digitally and track the review status online. This is the fastest and most common method for residential and commercial projects.
In person — You can also submit at the Phoenix Development Services Department at 200 W. Washington St., Phoenix, AZ 85003.
For most projects you will need:
- Completed permit application
- Site plan showing the property and proposed construction
- Full architectural drawing set
- Structural calculations (if required)
- Energy compliance documentation (for new construction and additions)
Step 4: Plan Review
Once submitted, a city plan reviewer examines your drawings for code compliance. Review times vary by project type:
- Express review (simple projects): Same day to 3 business days
- Standard residential: 10–15 business days
- Commercial: 15–30+ business days
If the reviewer finds issues, they issue a redline — a list of corrections required before the permit can be approved. You then revise and resubmit.
This is where having permit-ready drawings from the start pays off. A well-prepared set typically passes with few or no redlines, saving weeks on your timeline.
Step 5: Pay Permit Fees and Pull the Permit
Once your plans are approved, you pay the permit fee and the permit is issued. Fees vary based on project valuation — a typical single-family addition might run $500–$2,000 in permit fees, while larger commercial projects can be significantly more.
At this point construction can legally begin.
Step 6: Schedule Inspections
Building permits require inspections at key stages of construction — typically foundation, framing, rough mechanical/electrical/plumbing, and final. The inspector verifies that the work matches the approved drawings.
Once all inspections pass, you receive a Certificate of Occupancy (for new buildings) or a final sign-off, and your project is officially complete and on record.
Common Reasons Phoenix Permits Get Delayed
- Drawings missing required details (structural notes, dimensions, code references)
- Site plan doesn’t show required setbacks
- Energy compliance documentation missing
- Application submitted to the wrong department
- Drawings not to scale or missing a required view
All of these come down to the quality of your permit set. A drafting firm that knows Phoenix’s requirements will catch these issues before submission.
How Long Does the Phoenix Permit Process Take?
From submitting drawings to permit in hand, most residential projects take 3–6 weeks assuming no redlines. Projects that go back for corrections can take 2–3 months. Commercial projects vary widely based on complexity.
Working with a drafting firm experienced in Phoenix-area jurisdictions is the most reliable way to compress that timeline.

Frequently Asked Questions
Can I pull my own permit in Phoenix?
Yes — homeowners can pull their own permits for work on their primary residence. However, the drawings still need to meet all code requirements. Most homeowners work with a drafting firm to prepare the plans even if they submit the application themselves.
What happens if I build without a permit?
Unpermitted work can result in stop-work orders, fines, and a requirement to demolish or expose the work for inspection. It can also complicate a future home sale, as unpermitted additions must typically be disclosed.
Does Phoenix require an architect to stamp drawings?
For most residential projects under a certain square footage, an architect’s stamp is not required. A licensed drafting firm can prepare permit-ready drawings for most single-family residential projects. Commercial projects and larger residential projects may require a licensed architect or engineer of record.
How much do permit-ready drawings cost?
Costs vary by project scope and complexity. Contact ProCaDesign for a detailed quote — most projects receive a response within 3–5 business days.
