Maintenance Assessment Districts

A Maintenance Assessment District (MAD) is a legal mechanism by which property owners within specified boundaries vote to establish an assessment on their property tax bill to improve their community. MADs provide services over and above what the City of San Diego normally provides, often called a “special benefit.” These special benefits are determined by property owners and can include litter and graffiti abatement, trash collection and bulky item removal, as well as a variety of maintenance and economic development services. 

For most MADs in commercial areas, the Economic Development Department contracts with a nonprofit community-based organization for the management of the district. In the absence of a nonprofit community-based organization, the Economic Development Department works closely with community leaders to directly manage contracts with service providers. Click here to enter an address and see whether your business or property is in a MAD.

Other assessment district programs managed by the City include Business Improvement Districts (BIDs) and Property and Business Improvement Districts (PBIDs).

Maintenance Assessment Districts and the Economic Development Department

The Economic Development Department oversees nine MADs, while the Parks and Recreation Department manages 55 MADs across the City. Seven of the MADs administered by Economic Development are self-managed by nonprofit organizations, while Barrio Logan and Central Commercial are directly managed by the City. This means the City directly manages contractors to provide services to these MADs.
