How Long Does It Take to Get a Building Permit Approved?
Permit timelines genuinely range from a few days for the simplest projects to well over a year for complex commercial work, and most of that spread comes down to a handful of controllable factors rather than pure luck of the jurisdiction. Here's a realistic breakdown, and what actually moves the number.
There's no single national timeline
Every jurisdiction sets its own review capacity, staffing, and backlog, and every project type carries a different review depth — a permit that clears in under two weeks in one city can sit for two months in another with an identical scope, purely because of local volume and staffing.
Realistic timelines by project type
Across the projects we manage, these are typical review windows once a complete submittal is in the queue:
- Residential remodels and additions — roughly 10 to 15 business days
- Commercial tenant improvements — roughly 15 to 20 business days
- New construction — roughly 25 to 35 business days
- Zoning or variance approvals — roughly 30 to 45 business days, driven largely by public hearing scheduling
What actually controls the timeline
Beyond project type, the biggest lever is whether the first submittal is complete — a set that clears on the first pass avoids the resubmittal cycle entirely, while a rejected submittal can easily add four to eight weeks once you account for corrections and requeuing. Multi-discipline projects (architectural plus structural plus MEP) also take longer simply because more reviewers are involved, and any project needing a stamp from an out-of-state professional adds time if that isn't sorted out before submission.
The fastest path is a complete first submittal
The single biggest timeline lever within your control is submitting a complete, coordinated set the first time rather than treating plan check comments as an editing pass. That's the entire premise behind aiming for a 98% first-time approval rate — every week saved on review is a week closer to breaking ground.
A horizontal timeline graphic with four markers labeled Residential Addition (10-15 days), Commercial TI (15-20 days), New Construction (25-35 days), and Variance (30-45 days), with a small branching arrow off the timeline showing 'Resubmittal: +4-8 weeks' — conveys realistic permit timelines and the cost of a rejected first submittal.
