I've put together numerous condo docs, and budgets for them.
When a condo is first getting approved by the State, and before it is given the OK to break ground, the condo docs, including all budgets and rules, must be recorded at the Registry.
Often times the town's will require these docs as well- for the Planning Board, etc.
However, after that- there is no enforcement of any of these rules by the Town, generally.
And, the condo board can change their own rules- and the Town will know nothing about it.
So, best bet might be to call the Registry and see if they would share the info with you. They should.
If I can be of any help, with financing or anything else, please let me know.
MA General Law requires condominium documents be recorded at the appropriate registry of deeds. They are typically available for download from all Massachusetts' registries for free. If the condominium is a corporation, the by-laws portion of the documents might be part of the State corporate filings but this is unusual.
Minutes, financial and certain other documents are available to unit owners and mortgage holders from the Association.
But you could make friends with someone and they could give them to you.
