County permits, records, codes, and official contacts
Find county septic information
County FIPS lookup: Search the property location or a county FIPS code. SepticScope will take you to a source-checked county guide when one is complete, or a clearly labeled official-help page while local research is still in progress.
Search all 3,144 U.S. counties and county-equivalents.
Why the county matters: septic permitting may be handled by a county, health district, municipality, state agency, or delegated office. ZIP and city boundaries can cross county lines. Confirm the legal county in the property record before filing, buying, designing, or starting work.
