Who We Are & What We Do

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 the ever popular Annual Art & Garden Tour each Spring, the Walk to the Top celebrating the New Year, and other well attended events such as the Community Forum, Meet & Mingle, BackYard Chicken Coop Tours and more.
