In most Massachusetts buildings the first wreath appears the weekend after Halloween, and the last string of lights comes down somewhere around Valentine's Day. Boards that have not settled this in advance spend the next three months handling it one complaint at a time, which is the most expensive way to do it and the most likely to end badly. Twenty minutes at your October meeting is the whole fix. START WITH EGRESS, NOT WITH TASTE The genuine risk in decorations is fire and exit obstruction, and it is the one part of this that is not a matter of preference. Nothing goes in a way that narrows or blocks a corridor, a stairwell, a landing, a doorway or an exit route. Nothing obstructs or conceals exit signage, fire extinguishers, pull stations, sprinkler heads or standpipe connections. No live cut trees in common areas. No open flame - no candles in corridors or lobbies, ever. And watch extension cords specifically. Cords strung across a corridor floor, daisy-chained together, or run under a door are the most common decoration hazard in a condominium, and they combine a trip hazard with an electrical one. Require UL-listed lights, no daisy-chaining, and nothing plugged into a common-area outlet without board approval. Massachusetts fire codes govern combustible decorations and the obstruction of means of egress in residential buildings. The specifics depend on your building type and your local fire department's interpretation, which is why the genuinely useful move is a phone call: ask your fire prevention office what they expect in a residential common area. They answer that question every November and they would rather answer it now. THEN HANDLE DOORS AND BALCONIES Unit doors and door frames are usually common element surfaces even though they feel private, so decide what attaches and how. The practical rule most boards land on: command strips or over-the-door hooks yes, nails, screws, staples and anything adhesive that strips paint no, and the owner is responsible for any damage. Say it in writing rather than discovering it in January.
