Perc test planner

Pick your state: pick your state to see who regulates septic permits, who can do the soil evaluation, the official application page and the usual steps from test to permit.

Choose a state to see the rules we verified and official links. Or search your city, county or ZIP.

How to use it

Start with the property location, not the mailing address. If a ZIP crosses county lines, use the county result and double-check the parcel's actual jurisdiction.

Then use the page as a checklist: regulator, evaluator, application page, fees if published, and usual next steps. If anything looks unclear or outdated, contact the official office before you spend money.
