Start with the project.
Map the permit path.
A remodel, solar installation, HVAC replacement, or backyard structure can involve more than one application and more than one reviewing office. Permitech connects the scope and property to the reviews that may apply.
The permit-tech method
One project can create several permit paths.
Permitech does not start with a generic form. We break the work into the project facts, the property, the reviewing offices, the approvals that may apply, and the people responsible for each document.
- 01
Define the project
Start with what is being built, altered, installed, demolished, or used differently.
- 02
Resolve the reviewing authority
The mailing city is not always the permit desk. The address can route to a city, village, township, county, or another reviewing body.
- 03
Map every approval lane
Building, zoning, trade, fire, health, utility, and other reviews can apply in different combinations.
- 04
Coordinate people and documents
Identify what must come from the owner, contractor, designer, or another contributor before the next action is clear.

State pages are only the starting point. The permit answer that matters is the exact city, village, township, or county desk that will review the project.

Source-backed AHJ profiles
Building department profiles before project guides
Parent profiles collect official permit links, filing path signals, boundary context, and local construction history, then connect into the project-specific guide for that AHJ.
Project to permit path
Bring us the project, not a pile of permit links.
Start with the address and scope. Permitech identifies the likely reviewing authority, maps the approvals that may apply, and shows what still needs verification before the next step.
