About Perc Test by County
Perc Test by County is a free reference site from Directory Assistance Group. It is built to help people quickly find the right office, the right starting page, and the right questions before they buy land or begin a septic permit process.
Why this site exists
A simple question like "Who handles the perc test here?" can turn into a long search. In many places, septic permitting is handled locally, and the answer depends on the county, health district, or another local authority.
We built this site to make that first step easier. Instead of sending people through scattered pages and PDFs, we point to the likely regulator, the public application page, published fees when available, and the usual path from soil work to permit.
How to use it
Use the search to find your county, city, state, or ZIP. Then treat the result as a planning guide: confirm the office, review the official page, and call before scheduling work, buying land, or submitting an application.
If you spot an outdated office name, a broken form link, or a fee that has changed, send us a correction. Public information changes, and careful updates help everyone.
Who writes it
Perc Test by County is published by Directory Assistance Group, an independent publisher of free lookup tools and directories, and is written and maintained by a small editorial team. We are not lawyers, engineers, doctors, or government officials, and we do not claim to be. What we do is read the primary sources (statutes, agency guidance, university extension publications, and official court and health-department pages), turn them into plain steps, and link every claim back to where it came from.
How the site is paid for
The site is free to use and is supported by advertising, clearly labeled featured listings, and a few Amazon affiliate links. Advertisers do not choose or review our topics, and payment never changes what a guide says or the official details we list. Read our editorial standards and how we research for how we pick sources, correct mistakes, and keep ads separate from content.
Tell us what we got wrong
Rules change and local details vary. If you spot an error or an out-of-date figure, please send us a note with a link to the source. We read every correction, and fixes are logged on our site updates page.
