Many of the cities and towns in Marin County have ordinances regarding directional open houses signs--that have just recently begun being enforced.  With budget shortfalls everyone is looking for ways to generate revenue and the police are out in force picking up open house signs so they can collect the fines from agents wanting them back.

So when you're out there looking for a Sunday (or otherwise) open house, do not rely on directional signs to get there as many will only have signs at the property.

The Marin Association of Realtors provides a matrix that shows which cities and towns allow what.  You will see that most, if not all, only allow one.

So, if you are looking for open houses in Marin County you may want to dust off your Thomas Guide and your maps, or spring for a GPS if you don't already have one.  You cannot rely on directional real estate open house signs in Marin County anymore.
