Guilford County requires an inspection when new construction is begun on property with an existing septic system and/or well.
Published local O&M inspection intervals
Guilford publishes routine operation-and-maintenance inspection frequencies for qualifying systems: Type III single-pump systems every five years, Type IV systems every three years, and Type V and VI systems every year or six months depending on the system.
County publishes wastewater-specific local fees
Guilford County publishes separate fees for residential soil evaluations, construction authorizations by system type, alternative designs, and existing-system O&M inspections. Applicants should verify the current fee category before filing.
