Frequently asked questions

Do I always need a addition permit?
In most U.S. jurisdictions, yes — any addition work that affects structure, life-safety, or utility connections requires a permit. Permit Junkie checks your local rules against your project scope so you never guess.
How long does a addition permit take to approve?
Approval times vary by municipality and project complexity — from 24 hours for a counter permit to 6–12 weeks for plan review. Permit Junkie's Municipality Intelligence shows live processing times for every jurisdiction in our network.
What documents do I need for a addition permit?
Typical packets include an application, scope of work, site plan, scaled drawings, and licensed-contractor proof. PermitPal builds your personalized checklist in seconds based on your address and project type.
Can Permit Junkie submit the addition permit for me?
Yes. Our Permit Filing Concierge tier handles preparation, final AI review, and submission to your jurisdiction, then tracks status until it's issued.
