The California Tax Credit Allocation Committee (CTCAC) and the California Department of Housing and Community Development (HCD) have released the proposed 2027 updates to California’s Opportunity Map and Neighborhood Change Map and are inviting stakeholder feedback through November 16, 2026.

These mapping tools play an important role in California’s affordable housing finance system. Today, CTCAC and CDLAC use the maps to provide competitive scoring incentives and other benefits for qualifying affordable housing developments, and the Housing Development and Finance Committee (HDFC) has proposed incorporating both maps into its own scoring framework as well. Unlike some years, the proposed 2027 updates do not include methodological changes. Instead, CTCAC and HCD are proposing standard annual data updates using the most recently available information. According to the agencies, the Opportunity Map underwent a significant methodological overhaul in 2024 to improve transparency and consistency, while the Neighborhood Change Map was first introduced in 2024 and refined in 2025. No methodology changes were implemented in 2026, and none are proposed for 2027.

The Opportunity Map is designed to identify neighborhoods associated with strong educational, economic, and health outcomes for low-income households, particularly children. The map is intended to support California’s Affirmatively Furthering Fair Housing (AFFH) goals by identifying areas that provide greater access to opportunity and expanded housing choice. The Neighborhood Change Map serves a different purpose. It identifies communities experiencing significant economic and demographic change, including areas where rising housing pressures may require additional policy attention to preserve access and stability for lower-income residents and communities of color. These areas may represent opportunities to promote integrated communities while also addressing displacement risks.

For affordable housing developers, investors, lenders, and local government partners, these maps can significantly influence project competitiveness. Designations can affect scoring outcomes, basis boosts, and eligibility for various incentives across multiple state funding programs. As a result, even annual data updates can have meaningful implications for future affordable housing development opportunities.

CCAH encourages members to review the proposed maps carefully and provide feedback if updated designations may affect current pipelines, future development strategies, or project competitiveness. As these tools continue to influence funding decisions throughout California’s affordable housing system, stakeholder engagement remains critical to ensuring that mapping outcomes align with the realities of housing production, preservation, and fair housing objectives.

Comments on both mapping tools are due by 5:00 p.m. on November 16, 2026. Additional materials, including interactive maps and supporting documentation, are available through CTCAC’s Opportunity Map webpage.
