Changing Property Use Group

[J.R. Coffin]

I'm looking for properties in Chelsea, MA and Everett, MA and have been researching via the Assessor's Database, however, there are a number of use descriptions I've never heard of and can't seem to figure out. Any ideas what these mean?

AC LND IMP

RES ACLNUD

IND LD DV

COMM WHSE

RES ACLNPO

IND LD PO

Normally I would just breeze over them but I've had a lot of success changing property use groups by making a sound case to the city.
