What Are Massachusetts Impact Fees?
Massachusetts has no general impact fee statute, and its courts read fee authority narrowly — so one-time charges appear as Boston's linkage payments for large projects, sewer and water connection or privilege fees, and project-specific mitigation negotiated through site plan and 40B review.
Utility capacity, not formal impact fees, drives most budgets, with MWRA-area connection costs and Cape Cod wastewater programs standing out. Massachusetts figures on impactfees.org are model estimates for early comparison; confirm municipal connection and mitigation practice per town.
Massachusetts 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.
