If you install a bathroom without a permit, then they'll take action since it involves plumbing and electrical work.The only caveat is if the work wasn't done to code.

I'm excited about what's happening and, as a coding guy, want to fill some of the gaps myself. 

These are professionals with additional training and a stricter code of ethics.

Since each LLC has it's own company name and tax codes. 

1) The green card isn't necessary to transact, but its purpose to assure you that your property is up to code... 

This distribution is something I can look up in state code, but wondering if you know off the cuff.My angle was to use an Affidavit of Lack of Probate to avoid probate as decedent did not have a trust, joint tenancy with right of survivorship, community property agreement, ect.Once the affidavit is recorded with the county auditor, the net effect is to vest title to the "rightful" or legal heirs since there is no will.

I am looking for mass state codes as it relates to living space in the basement of a 3 family house.

@Kory Reynolds can you provide a citation for a code section, regulation, rev proc, rev ruling, or court case that supports the position that OP is a limited partner based on a facts and circumstances analysis that only takes into consideration the partnership agreement and dynamics between the partners?

Their base install ran $375 as I was allowed to wire all the EXIT signs, emergency lighting & hard wired smoke/CO detectors.Materials ran about $4,500 as I was able to use 3/4 Pex, but it took 18 long months of meticulous nook & cranny routing, sprinkler head installations & code inspections.

Also currently building an automated keycode service to set and delete codes for each renter for better security.
