L.A.’s Revised Adaptive Reuse Ordinance Poised to Boost Housing and Reduce Office Vacancy

Los Angeles’ real estate landscape is experiencing a shift, driven by revisions to its adaptive reuse ordinance that went into effect on February 1, 2026. These changes aim to incentivize the conversion of underutilized buildings into multifamily housing, address the city’s housing crisis, and reduce the growing office vacancy rates.

Expanding Eligibility and Streamlining Approvals

The original 1999 ordinance incentivized converting buildings into multifamily housing. The revised ordinance significantly expands eligibility by implementing a rolling 15-year rule. Buildings constructed in 2011 or earlier can now benefit from a streamlined approval process, with exemptions from certain project review requirements and density/height limits. Previously, buildings had to be built before July 1974 to qualify.

Incentives for Affordable Housing

Projects incorporating affordable housing units are now eligible for unlimited density bonuses, provided they meet specific city standards, including accessible amenities. Affordable or partially affordable projects can add two extra stories to their designs.

Expanding Geographic Reach

Unlike the original ordinance, which focused on downtown and Hollywood areas, the revised policy applies citywide. This broader scope allows for conversions of smaller buildings, such as two- and three-story structures, opening up latest possibilities for adaptive reuse projects. Architect Michael Bohn of Studio One Eleven referenced successful conversions in Santa Ana as a model for future L.A. Projects, where a two-story building formerly housing a food hall and career college was transformed into a 24-unit loft community with a ground-floor food market.

National Trends in Conversions

Los Angeles is part of a national trend toward building conversions. CBRE reported that 2025 marked the first year that conversions and demolitions surpassed new office deliveries nationally. As of the fourth quarter of 2025, L.A. Had seen 5 million square feet of office space converted or demolished, with an additional 4 million square feet planned or under construction. However, L.A. Still lags behind other major cities in the percentage of its office inventory in the conversion pipeline, with 1.8% compared to 3.3% in Manhattan, 8.7% in Miami, 2.9% in Houston and Dallas-Fort Worth, and 4.4% in Atlanta [USAToday].

Financing and Market Conditions

Phillip Sample, a senior vice president at CBRE, notes that financing is becoming more readily available for conversions, particularly for Class C office buildings. Investors are hesitant to finance upgrades for continued office use, but are more willing to fund multifamily conversions due to the high occupancy rates (97-98%) in that sector. The maturation of loans on office buildings is also driving interest in adaptive reuse, as owners seek alternatives to vacancies.

Sustainability and Community Benefits

Adaptive reuse offers significant sustainability advantages over new construction. Studio One Eleven estimates that converting buildings with eight to 14 stories can divert 25 million tons of debris from landfills and reduce embodied carbon by 60% to 80%. These projects also tend to receive more positive community reception than new builds, with less parking demand and lighter traffic flow. Adaptive reuse can create more vibrant, mixed-use districts, transforming formerly mono-use office areas into thriving communities.

Time and Cost Savings

Compared to the lengthy entitlement process for new construction (typically three to five years), conversions can be completed much faster, often in around 18 months, particularly when converting similar uses, such as a motel into permanent supportive housing. Cost savings are also realized, especially for steel-frame buildings requiring minimal structural upgrades, and through reduced parking requirements.

The 2028 Olympics Factor

The upcoming 2028 Olympic and Paralympic Games are adding urgency to these projects, as developers seek to capitalize on available building stock and meet deadlines before the games begin.

The revisions to Los Angeles’ adaptive reuse ordinance represent a significant step toward addressing the city’s housing challenges and revitalizing its commercial spaces. By streamlining approvals, incentivizing affordable housing, and expanding the geographic scope of the program, the city is poised to unlock the potential of its existing building stock and create more sustainable, vibrant communities.
