Plans to drop 110 factory-built modular homes on two wooded parcels just outside Yosemite National Park have turned a quiet corner of the Sierra into a full-blown fight over growth, fire danger and who gets to live near one of America’s most famous landscapes.
An Orange County developer has filed state-level housing applications that would cluster the homes on roughly 31 acres beside the small community of Yosemite West, a pocket of mainly vacation homes and cabins near the park’s western boundary. Nearby homeowners, tribal leaders and conservation groups are lining up in opposition, warning about wildfire risk, water supplies and a single, narrow road that already carries everyone in and out.
Formal filings and the SB 330 process
The project is moving through California’s SB 330 “builder’s remedy” track, and Mariposa County has posted the formal application materials along with a Housing Accountability Act notice on its website. According to Mariposa County, officials received the submissions on Nov. 25, 2025 and are still reviewing them while working to comply with the California Environmental Quality Act. The county has also set a deadline for written public comment tied to that notice.
What the developer is proposing
Application documents lay out a plan for 110 factory-built units, mixing one- and two-story modular homes with on-site parking spread across the two parcels. Reporting and county records show those parcels total roughly 31 acres and sold last August for about $1.7 million, according to the San Francisco Chronicle. The filings state that a portion of the units would be reserved for lower-income households, and the developer is seeking exceptions to local zoning under the state law it has invoked.
Tribal ownership and cultural stakes
For tribal leaders, the proposal lands at a particularly sensitive moment. The Southern Sierra Miwuk Nation recently reacquired about 900 acres of ancestral forest near the site and intends to manage it for cultural and ecological purposes. As Outside Online reported, tribal officials describe the return of that land as a way to support traditional stewardship, cultural practices and habitat restoration. Community members worry a permanent housing cluster next door could hem in those plans.
How the builder's remedy changes the rules
The developer is leaning on provisions in the Housing Accountability Act that limit how much a county can rely on local zoning to block qualifying housing when its state-required housing element is not certified. The California Attorney General has issued guidance this year urging local governments to process builder’s remedy applications and warning that ignoring state law can carry legal consequences. That legal setup is what allows a relatively remote, forest-zoned property to be pushed forward as a housing project under state rules.
County review, CEQA and the public record
Mariposa County officials say they are still processing the applications and have identified missing information needed to satisfy CEQA and county submittal standards. They have asked for more detail on road access, utilities, water supply, fire-safety measures and comments from other agencies. The county’s Housing Accountability Act posting, related correspondence, agency attachments and completeness letters are all available online. Written comments tied to the HAA notice must be submitted to the county today, according to the county posting.
Why neighbors and advocates are alarmed
Residents and the Yosemite West homeowners association say evacuation and emergency access top their list of fears. Adding 110 units, they argue, would significantly increase the number of people relying on the same tight roads that serve as their only way out. Local leaders and conservation groups also cite wildfire danger, water demand and wildlife movement as key worries, and some advocates contend the project would chip away at the buffer around one of the nation’s most visited national parks. Those concerns and the early backlash have been detailed by the San Francisco Chronicle.
Legal implications
If Mariposa County deems the applications complete and allows the project to advance, the fight could move into public hearings and, possibly, court over whether the proposal truly satisfies SB 330 and Housing Accountability Act requirements. State guidance emphasizes that local agencies have limited discretion on qualifying builder’s remedy projects and that denials can trigger lawsuits or enforcement actions. That combination of leverage for developers and risk for local governments helps explain both the strategy behind the filing and the intensity of the local response.
For now, the formal applications, county letters and agency comments make up the public record. Residents, tribal representatives and environmental groups are watching the calendar and county deadlines closely as the review grinds on.
