Is my crawl space Common?

I live on the 3rd floor of a 3-unit condo. There is a crawl space (I wouldn't call it an attic) that only I have access to. It is not insulated, which is a big problem for me in the winter. I'd like to add insulation.

I've checked my Unit Deed and my Master and there's nothing that indicates if my crawl space is my responsibility or the HOA's. The floor plans don't even include it.

The deed basically says I'm responsible for upkeep of my (walls-in) Unit and my Exclusive and Limited common areas...but the deed fully spells out what all those areas are, and the crawl space isn't mentioned. It also lists what common areas ARE the HOA's responsibility, and it's not included there either.

Are crawl spaces typically considered part of the roof (which IS common), or since I'm the only one with access to it, is it considered "mine"?

Technically is this a attic? Your plan shows a hip roof. If this is the area and you have access,i would think you could add insulation batting. Have you asked the board? Some HOA's require notification of any construction,but this seems minor,except for any safety issues,if any.

I don't think it is an attic. You can't even stand up in it. There's just enough head space for an HVAC.

Technically *I* am the board (one unit is completely disinterested in anything unless they have to pay; and the other owner just bought). I'm assuming it's my responsibility, I just want to make sure I do everything on the up and up.

An HOA has an obligation to make sure the common areas do not affect any individual owners property in a negative manner.

Considering where the OP lives, his heating bills will go through the roof if there's no insulation in that crawl space.

I am wondering why it's there though? My parents have a crawl space in their condo too but it's to get the HVAC system for the units. Their condo is responsible
for it's upkeep.

Tile has a problem in older areas where many older homes were turned into 2 or 3 Condo units and they be a cluster kiss with so few members, especially when all do not agree/contribute.

I have a nephew in Boston that specializes in buying older homes and converting them to 2-3 condo buildings. He knows the problem well.

I believe the OP is in a converted triple decker (3 levels, one unit/apartment per level) and as he is the upper unit, he has the only access to the attic. Quite common in older cities.

You are thinking side by side units where there would be a firewall between them.
