I am on the board of a tiny HOA. Changing the HOA rules is not for the faint of heart. I helped write the documents that govern this two unit building, and specifically had inserted that no unit can be rented for less than three months. I also ensured that the definition of whole unit was part of that clause. [MA standard practice is to include pages and pages of language that must be included in any lease should a unit become a rental, even for a short time, so that verbage is in there as well.] So, this HOA doesn’t allow short term rentals for a whole unit, doesn’t allow short term rentals of a room if the resident party is not the owner, and does allow short term rentals of a room if the owner is also occupying the unit.
Had no interest in a party house with a shared wall. This has become a real issue around here. Both sides were happy to sign this document.
I realize that this is not for everyone, but with a small condo building with no shared amenities [unless you count the driveway], this felt prudent.
I suspect that both sides will end up renting in those 3 month increments to take a sabbatical, travel, short term contract in another city at some point. That is different than having different groups of people tromping through the yard and shared back porch constantly.
