Septic permit expiration

[Thronester]

Does anyone know when a septic permit expires? I thought it was 2 years since the date it is issued

Plumbing permits expire if construction has not commenced within 120 days from the date of issuance, or if construction is abandoned or suspended for a period of 120 days after the work has commenced. However a plumbing permit issued for work on construction having a valid building permit will only expire when such building permit expires.

After talking with the engineering company. As long as the county doesn’t change their requirements, it’ll expire in 2 years. Phew!
