The San Mateo United Homeowners Association exists as a forum to communicate issues of concern to many of the City's homeowner and neighborhood groups. On occasion they coordinate efforts between neighborhood and homeowner groups where possible or needed and allow these groups to identify areas of common concern.

The San Mateo United Homeowners Association (SMUHA) mission is to actively support community involvement and improvement throughout the City of San Mateo. SMUHA presents 10 Ways to Help Your City, Your Neighborhood and Your Community.

The boundaries of San Mateo United Homeowners Association are the City of San Mateo and the immediate areas of influence surrounding the City.
