Medium confidence. Part of at least one section falls in a different district on the county map, or some of its parcels list a different unit. Some lots may have a different rate — check the address on MCAD.

Check a specific address: districts here are mapped from county GIS boundaries and checked against MCAD parcel records, but individual lots can still differ, and PID assessments and HOA dues are not in the rate. Look up the exact address on the official MCAD property search; the property record lists every unit that taxes it.
