The Code Enforcement Office will verify if the proposed construction is designed to meet applicable codes, statutes and ordinances. Projects must have the necessary planning, public safety, public works, state fire marshal, state electrical nspector, and Department of Environmental Protection clearances. 

Depending on the complexity, the time frame for building permit approval is usually less than five days. The permit review time allowed by the Land Use Ordinance is 14 days.


Property owners are responsible for complying with all city ordinances and codes. The Code Enforcement Office is available to answer any questions about any planned construction activities.

Plumbing / Septic

Internal Plumbing

An internal plumbing permit is required for installation or replacement of all water distributing and drainage pipes, water storage tanks and water heaters and installation of all new faucets, valves and plumbing.

Permits are valid for 24 months after the date of issuance.

Permits are not required for the clearing of stoppages and repairing of leaks in all water distributing and drainage pipes, valves, and faucets, provided the work does not require the replacement or relocation of any pipes.

External Plumbing

External plumbing permits are required for any work related to subsurface waste water disposal systems except for minor repairs to pumps, clearance of a stoppage, sealing of a leak in the septic tank, building sewer or effluent line, adding fill material to a fill extension.

External plumbing permits or subsurface wastewater disposal (septic) system (SSWD) applications are required to be completed by a State of Maine licensed site evaluator.

The application then needs to be reviewed and permitted by the Local Plumbing Inspector at the Code Enforcement Office. If a SSWD application has a signed, dated permit label affixed to page one of the permit application form, the permit is approved.

Sewer & Water Hookups

Code Enforcement is responsible for public sewer and water hook-up permits.

The Gardiner Public Works, Water and Wastewater Departments are responsible for Code and Ordinance administration.

Public sewer and water hook-up permits include two classes: residential and commercial service and establishments producing industrial wastes.

In either case any new, relocation, alteration, use, connections with or opening into public sewer and water must first receive an approved sewer and water hook-up permit from the Code Enforcement Office and any other applicable state or federal agency prior to the commencement of construction.

Any questions associated with public sewer and water connections should be directed to Public Works, Water, or Wastewater Departments.
