Direct answer
The short answer for Boston, MA
In Greater Boston, meth residue work in brownstones, triple-deckers, and condo stacks goes on without a set Massachusetts number for moving back in. Honest sale and turnover packets rest on a few things. These include MassDEP waste-site contacts and city public health questions. They also include plaster rooms sealed up for winter, accredited wipe maps, and EPA voluntary guidance. A made-up state microgram rule has no place in them.

Local planning context
Brick rows in the South End and Back Bay, triples in Dorchester and Jamaica Plain, and older condo conversions pack homes around shared stairs. Many also share basement mechanical rooms. Massachusetts has no statewide numeric meth limit for moving back in. Massachusetts offers no parallel to the rule California set in section 25400.16. So Boston owners should set a written pass level for their own address. Agree on it with the industrial hygienist, a trained chemical-safety expert. Include the accredited lab and any lender or buyer who has demands. Do not invent a Massachusetts clearance microgram.
The Massachusetts Department of Environmental Protection (MassDEP) runs Waste Site Cleanup and emergency response. Those are the state contacts when abandoned containers, spills, or chemical threats remain. The Boston Public Health Commission takes city environmental health questions once a scene is stable. Tell cooking apart from smoking-only residue. Cooking leaves solvents, raw ingredients, reaction waste, and stained fixtures. Smoking alone can still coat plaster lath, soft goods, and duct dust in stacks sealed with storm windows.
Stacked porches, plumbing chases, and shared laundry let residue move from floor to floor. That is the main planning problem in these buildings. Soft wood trim and old plaster hold residue. Paint, ozone machines, and fragrance cannot replace mapped wipe results. Tie disclosure wording to what was tested, removed, and tested again.
