Cumberland County does not issue building permits for incorporated municipalities; each city and town manages its own building, zoning, and code enforcement. The county government primarily handles unincorporated territories and specific regional services, while municipalities maintain primary jurisdiction over all development and land-use overlays.
How this fits with the state
The state authority here is Maine Office of Professional and Occupational Regulation; local building departments. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
