Two identical additions, two cities forty minutes apart: one is permitted in three weeks, the other takes five months and two rounds of corrections. Nothing about the drawings explains the gap. The jurisdiction does.
What a jurisdiction actually controls
Your city or county decides far more about your project's cost and timeline than most homeowners expect:
- ✓Which building and energy code edition is in force, and any local amendments
- ✓Whether your project needs planning approval before it reaches building plan check
- ✓How many review cycles are typical, and how long each one takes
- ✓Which consultant reports are mandatory — soils, survey, arborist, drainage
- ✓Whether design review, historic review or a neighbourhood notice applies
Why review times differ so much
Most of the variation is staffing and process, not strictness. A well-resourced counter with an over-the-counter path for simple residential work turns a small addition around quickly. A department with one plans examiner and a paper intake queue does not, no matter how clean your set is.
The rest is code layering. Seismic zones, wildland-urban interface areas, coastal overlays and hillside ordinances each add sheets to the set and reviewers to the queue — and they compound.
How to read yours before you commit
Look up three things before you sign a scope: the code edition in force, the published plan-check turnaround, and whether your parcel sits in any overlay district. Our jurisdiction database scores all fifty-two US jurisdictions on exactly these factors, and the estimate engine folds that score into the range it shows you.
“A clean set does not make a slow city fast. Knowing it is slow before you start is what keeps the project calm.”

None of this is a reason to hesitate — it is a reason to plan. An architect who has submitted in your jurisdiction before knows which sheets that plans examiner reads first, and that knowledge is worth more than any shortcut.
