Frequently Asked Questions
How do I know if I need a building permit?+
Whether you need a building permit depends on your project type, scope, and local jurisdiction. Most structural work, electrical, plumbing, and projects over a certain size require permits. Rules vary dramatically by city — a project that's exempt in one city might require full engineering plans in the next. Our permit checker gives you a location-specific answer in minutes.
What happens if I build without a permit?+
Building without a required permit can result in fines ranging from $500 to $10,000+, orders to tear down or redo the work, difficulty selling your home (unpermitted work shows up in title searches), insurance claim denials, and personal liability for injuries. The cost of checking is always less than the cost of getting caught.
How much does a building permit cost?+
Building permit costs vary widely by project and location, typically ranging from $50 for simple projects like fences to $2,000+ for major renovations. Many jurisdictions charge based on project value (usually 1–2%). Our reports include exact fee schedules for your specific project and jurisdiction, so you know exactly what to budget.
How is this different from just calling the building department?+
Building departments are notoriously hard to reach — long hold times, limited hours, and staff who often can't give definitive answers over the phone. Our reports compile information from official sources into one clear document, including fee schedules, document requirements, and application steps that would take hours to find yourself. Plus, you get a permanent PDF record to share with contractors or lenders.
What projects does this cover?+
We cover 50+ project types including decks, fences, bathroom and kitchen remodels, roof replacement, room additions, ADUs, electrical work, plumbing, HVAC, solar panels, pools, sheds, garages, basement finishing, and more. If you don't see your project, choose "Other" and describe it — our AI engine can research any residential construction project.
Is there a money-back guarantee?+
Yes — 100% money-back guarantee. If your report doesn't meet your needs for any reason, contact us and we'll refund your purchase. No questions asked.
