May have an additional district or assessment. Some sections here had too few parcel records to cross-check, so a management district, defined area, or PID could apply that is not shown. 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.
