How Long Does It Take to Get a Building Permit?
The honest answer is that it depends entirely on the lane your project falls into. Simple trade permits are often issued over the counter the same day you apply. A kitchen remodel with new plumbing might wait two weeks. A home addition can sit in plan review for a month or more. Knowing which lane you are in, and what moves applications between lanes, is how you plan a realistic schedule.
Simple over-the-counter permits such as water heater swaps are usually issued the same day. Most residential remodels and additions take 1 to 6 weeks in plan review, with complex or commercial work taking longer. Incomplete plans, zoning reviews, and peak building season are the biggest delays, and complete first submissions move fastest.
The short answer: same day to six weeks
Permit timelines fall into rough bands. Over-the-counter permits, for work like water heater replacements, re-roofs, and furnace swaps, are typically issued the same day or within a few business days. Fast-track or express permits, used by cities like Tucson for qualifying residential projects, aim for same-day or 15-day review. Standard plan review for remodels, additions, and structural work typically takes 2 to 6 weeks depending on the city and the season. Complex and commercial review, for new buildings and commercial build-outs, runs 6 to 12 weeks or more, especially when it involves zoning, fire, and environmental reviews.
The review lanes cities use
Cities sort applications by risk. Tucson's system is a clear example: an Express lane for same-day permits on simple projects, a Fast lane with a 15-day target, a Standard lane with a 30-day target, and a Complex lane for everything that needs full review. Other cities use different names, but the logic is the same everywhere. The more your project affects structure, occupancy, or public safety, the longer the lane. Submitting a deck permit in January may sail through in a week; the same permit in May, when every contractor is booked, can take three.
What slows an application down
Incomplete plans are the number one delay. Missing details, illegible drawings, or plans that do not show structural connections send the application back for corrections, and every round trip resets the clock. Zoning review is second: if your project touches setbacks, lot coverage, or use rules, it may need a separate zoning review before the building permit can move. Historical or HOA approval can add weeks if your property sits in a historic district. Peak season matters too: spring and summer backlogs stretch every lane. Finally, corrections cycles compound: the first correction is fast, but each additional round is slower because the reviewer is now juggling your file with new applications.
What happens during plan review
Once your application is accepted, it circulates. A plans examiner checks structural details against the building code. Plumbing, mechanical, and electrical reviewers check their systems. Zoning staff confirm setbacks and use. Fire reviewers check egress and alarms where required. Each desk can issue corrections, and the permit issues only when every desk signs off. You do not need to manage this routing yourself; the permit office does it, but knowing the desks exist explains why a "simple" permit sometimes takes three weeks: it waited in four queues.
How to get your permit faster
Submit complete plans the first time. Include a site plan, floor plans, elevations, and structural details for anything load-bearing; most city websites publish a checklist of exactly what each permit type needs. Apply early in the year if you can, before the spring rush. Respond to correction letters within days, not weeks, because corrections are usually reviewed faster than new applications. If your city offers pre-application meetings or express lanes, use them. And never start work while the permit is pending: getting caught means a stop-work order and an investigation fee, which costs far more time than the review ever did.
After issuance: inspections take time too
Budget the permit timeline plus the inspection schedule. Most permits require inspections at set stages, such as rough-in (before walls close) and final. Each inspection needs to be scheduled, often 24 to 48 hours out, and a failed inspection means fixes plus a re-inspection visit. Plan your contractor's schedule around these visits rather than hoping they line up by luck.
This is general information about typical timelines, not a guarantee and not legal advice. Your city's current workload is the real timeline; call the permit office or check its published targets before you promise a start date to a contractor.

Building permit timeline questions
How long does it take to get a building permit for a house?
A new single-family home typically takes 4 to 12 weeks in plan review, depending on the city and complexity. Custom homes with structural engineering, septic, or zoning variances take longer. Over-the-counter permits for simple work are same-day, and standard remodels usually take 1 to 6 weeks.
How long does it take to get a building permit for an addition?
Home additions usually take 2 to 6 weeks in plan review. Additions need structural plans, site plans showing setbacks, and often zoning confirmation, so they rarely qualify for same-day lanes. Peak building season can push the wait toward the high end.
Can you expedite a building permit?
Many cities offer express or fast-track review for qualifying projects, sometimes for an added fee. Tucson, for example, runs Express (same-day), Fast (15-day), and Standard (30-day) lanes. Submitting complete plans and responding to corrections quickly is the most reliable way to move fast in any city.
Why is my building permit taking so long?
The most common reasons are incomplete plans sent back for corrections, a separate zoning review the applicant did not expect, backlog during spring and summer, and multiple correction rounds. Call the permit office and ask for the status of your specific application; they can usually tell you which review desk is holding it.
Can I start work while my permit is pending?
No. Starting work before the permit is issued is working without a permit, and most cities respond with a stop-work order plus an investigation fee that is often double the normal fee. Some cities allow limited early work like demolition under a separate permit, but ask first.
