Norfolk County does not restrict rainwater harvesting. MA has no statewide restrictions on residential rain barrel or cistern use. Many Norfolk County towns offer rain barrel rebate programs.
Rainwater harvesting is unrestricted in Norfolk County. Massachusetts has no state-level limit on residential rainwater collection — rain barrels and cisterns may be installed without special permits for garden irrigation, lawn watering, and other non-potable use. MWRA member communities (including Quincy, Brookline, Milton, Norwood, Dedham, Weymouth, Canton, Stoughton) often offer discounted rain barrels through summer promotions. Large cisterns connected to plumbing systems trigger 248 CMR (state plumbing code) permits. Potable use requires treatment meeting Title 310 CMR 22 (Drinking Water). HOAs may restrict visible placement but cannot ban collection outright. Cross-connection to municipal water requires backflow prevention under 310 CMR 22.22.
No county enforcement. Standard residential collection: no penalties. Large cistern without plumbing permit under 248 CMR: $100-$500 building code fine. Cross-connection violations: up to $5,000.
