Works for roofing, decks, fences, electrical, plumbing, additions, and new construction.
What moves this number: plan review cycles, required inspections, current permit volume at the city, and how complete your application is on the first submittal.
Estimate only — actual timelines vary by jurisdiction, project complexity, and current permit volume. Contact your local building department for current processing times.

How long does a building permit take?
It depends on scope. Simple residential permits — roofs, fences, decks — are often issued over the counter or within a week. Trade permits and additions typically run 1-3 weeks because they need plan review. New construction is the longest at roughly 3-6 weeks or more, since plans route through multiple departments and often come back with correction requests.
Why do permit timelines vary by city?
Staffing and volume. A busy metro processing tens of thousands of applications per year runs longer queues than a smaller market, and cities differ on which project types qualify for fast-track or over-the-counter issuance. Seasonal surges matter too — spring and summer application spikes stretch review times everywhere.
What slows down a permit approval?
The most common culprit is an incomplete first submittal — missing site plans, unsigned documents, or wrong valuations trigger a correction cycle that can add weeks. Other frequent delays: plan review comments requiring resubmittal, zoning or variance issues, unregistered contractors, and high seasonal permit volume at the city.
Does project type affect permit time?
Significantly. Like-for-like replacements (roof, water heater, fence) often skip plan review entirely and are issued in days. Anything structural — additions, new construction — requires full plan review across building, zoning, and sometimes fire and public works, which multiplies the timeline.
How can I speed up my permit approval?
Submit a complete application the first time — that alone avoids the biggest delay. Verify zoning before applying, use contractors already registered in that jurisdiction, respond to correction requests the day they arrive, and watch your permit status so nothing sits unnoticed. ClearedNo automates that last part: it monitors the portal and emails you the moment your status changes.
Once you apply, ClearedNo watches the city portal for you and emails you the moment the status changes — cleared, approved, failed inspection, or hold. No more morning portal checks while you wait. Unlimited permits, $79/month flat, first month free.
