Who regulates septic systems in Connecticut?

Connecticut regulates septic systems ("subsurface sewage disposal systems") under the state Public Health Code (RCSA 19-13-B100a and 19-13-B103), administered by CT DPH with permits issued by local health departments/directors.

Is a septic inspection required to sell a home in Connecticut?

No. Connecticut does not require a septic inspection as part of a home sale. State legislative research confirms neither buyers nor sellers are legally required to obtain a home or septic inspection. Sellers of most 1-4 unit residential properties must complete a Residential Property Condition Disclosure Report (Conn. Gen. Stat. Ch. 392, Sec. 20-327b) which includes a sewage-disposal section (system type, pumping history, known problems), but this is disclosure, not a mandatory inspection.

Are there pumping-frequency requirements in Connecticut?

No statewide codified pumping-frequency interval was found in this research pass.

Permit and registration requirements

Installation and repair require a permit from the local health department under the state Public Health Code.

Notable Connecticut-specific rule

Connecticut runs a two-tier statewide professional licensing system through CT DPH's Environmental Practitioner Licensure program: a higher-barrier "Installer" license (requires verified prior installs or reciprocity plus exam) and a lower-barrier "Cleaner"/pumper license (exam-only, no experience prerequisite, ~$20).
