Full Breakdown

Imperial County has adopted the 2022 California Plumbing Code, including appendices, for all plumbing work in the unincorporated area (§ 91004.00). Under § 91004.02, stopping a leak or clearing a stoppage does not need a permit, but if a trap, drain, waste or vent pipe is defective and must be removed and replaced with new material, that is treated as new work requiring a permit and inspection. An additional sewer permit is required when an interceptor trap is installed alongside a new building sewer.

Violations & Fines

Replacing defective plumbing pipe or fixtures without first pulling a permit violates §§ 91004.00 and 91004.02; the Building Official may issue a citation under § 91004.05.
