Open house signs sit in a gray zone of municipal codes and HOA covenants, and the rules change from one city to the next. Getting it wrong means removed signs, small fines, and a sour relationship with an HOA you'll be working near for years. What follows is general guidance, not legal advice. Your city's sign ordinance is the real authority.
The right-of-way problem
The strip between the sidewalk and the street usually belongs to the public right-of-way, and many cities ban private signs there. It's also exactly where everyone wants to put a sign, which is why it's the most common reason code enforcement picks one up. If you don't know your city's position, ask the listing office, or read the ordinance once and know it forever.
What HOAs care about
Mostly three things: how many signs, where, and for how long. Some limit size or ban signs on common areas entirely. Some want everything down within an hour of the event ending. A five-minute call before the weekend answers all of it and costs nothing. Showing up already knowing their rules buys goodwill that outlasts the listing.
Timing and neighbors
- Signs go out the morning of the open house, not on Thursday.
- Everything comes down the same day. A sign standing on Monday is a complaint by Tuesday.
- Stay off private lawns unless the owner said yes.
- Never block the sightline at an intersection, whatever the ordinance says. It's dangerous.
The same-day-takedown rule is the one that gets broken by accident, because taking every sign down requires remembering where every sign is. Keep a record when you place them. The etiquette follows from there.
