What Are Maine Impact Fees?
Maine municipalities may adopt impact fee ordinances under 30-A M.R.S. § 4354, which requires fees to be reasonably related to development impacts and earmarked for identified capital projects — commonly roads, sewer, schools, recreation, and public safety in southern Maine's growth towns.
Fee adoption clusters in Cumberland and York counties, where housing pressure is strongest; much of rural Maine charges only utility connection fees. Maine figures on impactfees.org are model estimates scaled to town size — confirm ordinance schedules with each town office.
Maine figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
