Legal Question in Real Estate Law in Massachusetts

Re: Landlords rights to keep common area door unlocked

I believe without looking up the law that the answer is 3 units, under the State Sanitary Code.

I got that opinion from a well-respected landlord/tenant lawyer prominent in the Boston area, Atty. A. Joseph Ross. (I'm in Newton.) He wasn't 100% certain and he didn't look it up, but his vague and offhand recollections have been pretty accurate in the past.

I assume you have more than three. If you have only 4 and you want me to check for sure, call me; I'll want to know also what city or town you are in as well.

Sorry if it's not what you wanted to hear.
