How municipal tax incentives work

In San Diego the primary local mechanism for property tax relief on historic properties is the Mills Act contract program administered by the City planning division and reviewed by the Historical Resources Board. A Mills Act contract is a binding agreement recorded against title that provides reduced property tax assessments in exchange for agreed preservation and maintenance work; eligibility, review criteria, and timing are set by the City program and state enabling law City Mills Act page[1]. Program details, nomination deadlines, and Board hearing schedules are published by the City's historic resources program San Diego Historic Resources Program[2].

Start early: Mills Act nominations follow council and Board calendars.

Eligibility and common requirements

  • Property must be designated historic by the City or listed on an eligible register.
  • Owners usually submit a nomination and application timed to Historic Resources Board hearings.
  • Contracts require ongoing maintenance and preservation work consistent with the Secretary of the Interior standards.
  • Agreed work may be inspected periodically by City staff.
A Mills Act contract is recorded on property title and binds future owners.
