Land Use and Zoning California 4 Minutes Read · published February 02, 2026 Flag of California

Los Angeles, California property owners restoring historic buildings can combine federal and local tax tools with city permits and preservation rules. This guide summarizes the main incentives used in Los Angeles, identifies the enforcing departments, explains common compliance steps, and points to official applications and contacts so owners and contractors can plan restorations with legal certainty.

Historic Incentives Overview

Key programs often used on Los Angeles projects include the federal Historic Tax Credit for certified rehabilitations, and the local Mills Act contracts administered by the city Office of Historic Resources. Permits and local preservation reviews are required for work in historic districts or on designated resources. See the federal guidance for the 20% rehabilitation tax credit and the City of Los Angeles Mills Act program for local contract details: National Park Service - Tax Incentives[1], City of Los Angeles - Mills Act[2].

Start early: tax and permit reviews run on different schedules and both affect project timing.

Permits, Reviews, and Approvals

Most rehabilitation work requires building permits and, where applicable, review by the Office of Historic Resources or a local HPOZ board. The Los Angeles Department of Building and Safety issues permits and enforces building code compliance; applicants should consult LADBS for submittal requirements and compliance guidance LADBS - Permits[3].

  • Obtain building permits for structural, electrical, plumbing, and alteration work.
  • Submit preservation review applications if the property is on the Local Register or inside an HPOZ.
  • Document existing conditions and historic features for tax-credit certification and permit review.
Mills Act contracts are negotiated locally and must be approved by the City.

Penalties & Enforcement

Enforcement is handled by multiple city bodies depending on the violation: LADBS enforces unpermitted construction and building code violations; the Office of Historic Resources and Cultural Heritage Commission handle preservation-related violations and conditions for designated resources or HPOZ rules. For federal tax credits, improper claims can be adjusted by the IRS and may trigger recapture provisions per federal tax law; see the National Park Service guidance for program rules and certification criteria.[1]
