An educational, cited reference for homeowners — not a claim that ClickSeptic services New York today. ClickSeptic has zero live markets anywhere yet.
Short answer: New York delegates most onsite wastewater oversight to county and local health departments rather than regulating directly at the state level. NYSDOH sets minimum statewide design standards (Appendix 75-A, "Wastewater Treatment Standards - Residential Onsite Systems"), but permitting, inspection, and enforcement happen locally -- Suffolk and Nassau County each run their own programs, and rules vary meaningfully from county to county.

No statewide law requires a septic inspection at the time of home sale. Sellers of 1-4 family homes must complete New York's Property Condition Disclosure Statement (amended, effective July 1, 2025), which asks about septic/cesspool type, age, and last-pumped date, but this is a disclosure obligation, not an inspection mandate. Some individual counties impose their own transfer requirements -- for example, Cayuga County's Sanitary Code mandates a certified inspection and tank pumping before any property transfer, valid for one year. Always check the specific county.
No statewide pumping-frequency law. NYSDOH's homeowner guidance recommends periodic pumping based on tank size and household use, but this is guidance, not a codified interval. Some counties layer on their own rules.
Permit and registration requirements are set and issued locally (by county or town health departments), not by the state directly. There is no single statewide septic permit.
Suffolk County's July 1, 2019 rule ending cesspool-for-cesspool replacement (any replacement must include at minimum a septic tank and leaching structure) is the best-documented example of a New York county going further than state minimums. This is a county rule, not a statewide one.
