The Grossmont-Mt. Helix Improvement Association (GMIA) is one of the oldest and largest associations of its type in San Diego County. Formed in 1938 as a result of community concern for the lack of adequate land use planning and zoning type requirements, we are a non-profit public benefit corporation. We represent over 7,000 single-family residences with a population approximating 20,000 people. Our region includes parcels east of Bancroft Drive, south of El Cajon, generally north of SR94 and Rancho San Diego, and west of SR54/Jamacha Rd. (Please see map)

The primary mission of GMIA is to work on behalf of all GMIA community members to ensure that the quality and character of our community is preserved and enhanced. Unlike a typical “homeowner's association,” GMIA does not own any property or facilities, nor is it responsible for any property maintenance. GMIA is served by an unpaid Board of Directors (elected by the GMIA membership) and has no paid officers or employees. The GMIA Board works with County and regional governmental entities to help resolve issues that impact our community such as transportation, traffic control, planning and land use, zoning, code enforcement, as well as crime prevention and law enforcement.

GMIA organizes five great events each year:

  • Our acclaimed spring Annual Art & Garden Tour highlighting beautiful private gardens in our region.
  • A popular Succulent Swap to encourage drought tolerant landscaping.
  • The winter Walk to the Top of Mt. Helix to celebrate the New Year.
  • A fall Community Forum focused on timely issues of local interest.
  • Our summer Annual Dinner held at the magnificent amphitheater at the Water Conservation Garden and featuring an opportunity to interact with County Supervisor Dianne Jacob.
These events are always well attended by members who enjoy the chance to get to know their neighbors and celebrate our wonderful community. Please check out photos from these past events on the event tab on this web site.
