How long does it take to get a building permit approved?
Factors that affect timing
Approval time depends on the project's complexity, the completeness of your application, and your local building department's workload. A permit for a water heater replacement might be issued same-day or within a few days. A kitchen remodel with structural changes could take 2–4 weeks. New home construction often takes 4–8 weeks or more.
Many jurisdictions offer over-the-counter permits for simple work, where you can walk in and get approval immediately if your plans are straightforward. Others require a full plan review, which can take longer. Seasonal demand—like spring and summer—can also slow things down.
- Simple repairs (e.g., roof patch, water heater): 1–5 days
- Minor remodels (e.g., bathroom, kitchen): 1–4 weeks
- Major remodels or additions: 4–8 weeks
- New single-family home: 6–12 weeks or more
- Solar installations: 1–3 weeks (varies by state)
How to speed up the process
Submit a complete, accurate application with all required documents. Missing information is the most common cause of delays. Consider hiring a professional who is familiar with local codes to prepare your plans. Some departments offer expedited review for an additional fee, and many now accept digital submissions, which can reduce back-and-forth.
If you're working with a contractor, they often know the local process and can help avoid common pitfalls. You can also check your building department's website for current processing times, which many post online.
Common mistakes
- Submitting incomplete plans and then having to resubmit, which restarts the clock.
- Assuming all permits take the same time; a simple electrical permit is much faster than a structural one.
- Not factoring in inspection scheduling delays after the permit is issued.
