In a high-stakes clash over what “affordable housing” really means in Marin, the Marin Housing Authority has sued the heir to a Marin City below-market townhouse, accusing him and his late mother of loading the property with loans and a reverse mortgage that violated program rules. The agency wants a judge to enforce strict resale restrictions that keep Below-Market-Rate homes affordable, and it is prepared to take the unit back if the court allows it.
The lawsuit, filed Thursday in Marin County Superior Court, names Warren Duane Jackson as the defendant, according to the Marin Independent Journal. The complaint traces the townhouse back to its purchase in 1997 with a HUD subsidy and says that over time it became heavily encumbered by a series of loans and a reverse mortgage. Kevin Rose, who has spoken publicly about the case, told the paper that the heart of the dispute is whether it is fair to try to take a home from people the BMR program is supposed to protect.
BMR Rules Designed To Keep Homes Affordable
Marin’s Below-Market-Rate program is built to keep a lid on long-term housing costs, not to fuel equity extractions. As the Marin Housing Authority explains, owners of BMR units face tight limits on borrowing and on resale prices so that homes remain within reach of moderate-income buyers.
Under the rules, total encumbrances on a BMR unit cannot exceed 90% of the restricted resale price. Certain life events, including the death of the title holder, can also trigger resale or repurchase options that allow the authority to step in and keep the home in the affordable pool instead of letting it drift toward market-rate territory.
Authority Says Loans Put The Unit Out Of Bounds
The complaint focuses on a series of loans that, according to the authority, pushed the Marin City townhouse far beyond those limits. It alleges that the late owner, Shirley Hall, took out a $900,000 reverse mortgage in 2015 that later went into default. After Hall’s death, Jackson is alleged to have obtained a $468,000 loan from CalCap Lending LLC in 2022 and a $560,000 loan from Quontic Bank in 2023.
The authority argues that those encumbrances, combined with a market-rate listing for the townhouse at 45 Terrace Drive in Marin City on March 20, 2024, violate the BMR program’s borrowing caps and justify the agency’s move to exercise its purchase option. In a cross-complaint, Jackson counters that the county and the authority waited roughly 89 months before taking steps to use their repurchase rights. Mediation in the case is scheduled for Feb. 24, 2026, as reported by the Marin Independent Journal.
How Common Are These Disputes?
The conflict lands in a relatively small but closely watched corner of Marin’s housing market. The BMR program overseen by the authority covers a few hundred homes, and when those units change hands the process runs through a controlled system of lotteries and real estate agents that is designed to keep the homes in the program and available to qualified, moderate-income buyers.
According to the Marin Housing Authority, the agency currently administers more than 300 BMR properties across the county. Each one comes with a thick stack of restrictions that, in theory, prevent exactly the kind of aggressive leveraging that is now at the center of this lawsuit.
Next Steps
The Feb. 24, 2026 mediation will give both sides a chance to settle before the case turns into a drawn-out courtroom battle. The authority has signaled that if it concludes the rules were broken, it is ready to invoke its purchase option to safeguard the program and keep the townhouse in the affordable inventory.
Advocates for BMR homeowners and for stricter program enforcement say the case is likely to be closely watched across Marin. However it ends, the dispute highlights a growing tension in high-cost counties: how to preserve limited affordable housing stock while recognizing the very real financial strain on longtime owners and the family members who inherit their homes.
