Condo trusts and insulation association approval is rarely a question of whether work happens “inside your unit.” A cold bedroom, exterior-wall draft, garage-floor complaint, or shared-wall issue can each lead to a different approval path.
In a Massachusetts condominium, a wall, roofline, attic, facade, party wall, window opening, or garage ceiling may sit between individual comfort and shared property responsibility. The surface you can touch is not always the boundary that controls an alteration.
