A seven-story apartment building is headed for the site of one of West Hollywood's most notorious eyesores. Vanowen Management LLC has proposed a full block-fronting, townhouse-style structure with 12 two-bedroom units at 1030 N. Sierra Bonita Avenue, the lot where a decaying duplex known to neighbors as the Hell House once stood before it burned and was torn down.
The proposal, first reported by Urbanize LA, describes a contemporary exterior of stucco and other finishes, with projecting and recessed window bays framed by deep squared elements. The design comes from architecture firm 64North, which is also behind a similar six-story, 12-unit infill project at 948 N. Hayworth Avenue proposed by Blackacre LLC and covered in October 2025 using the same state density bonus incentives, according to LA YIMBY. West Hollywood's Design Review Subcommittee has already reviewed that comparable Hayworth Avenue project, per the same Urbanize LA report.
From Blighted Duplex to Density Bonus Project
The 6,501-square-foot lot's path to redevelopment is rooted in a legal mechanism spelled out in a city public notice: the project includes two deed-restricted affordable units, according to the City of West Hollywood. The project uses density bonus incentives. That density bonus is what permits a structure far larger than standard zoning would otherwise allow on the parcel.
The project includes six parking spaces for 12 units.
The Site's Dark History
Before any of this, the property was known simply as the Hell House. Neighbors gave it that nickname after years of decay, squatting, and alleged drug activity, a downward spiral that culminated in a major fire on Thanksgiving Day, November 23, 2023. The blaze occurred at the property.
That pressure led the City of West Hollywood to issue a demolition notice, and the duplex was demolished on January 4, 2024, as reported by the Beverly Press. The teardown, overseen by city officials after sustained public outcry, removed the duplex, and an infill housing proposal later emerged.
Ownership Changes and Rising Land Values
Public land records tracked by Zillow show the 6,317-square-foot parcel sold in August 2024 for $1,980,594. FMB Development was identified as the owner in January 2024. The parcel's assessed value has since climbed to $1.79 million in 2026, reflecting the site's shift from liability to opportunity once the blighted structure was gone.
Ahead of formal Planning Commission review, the City of West Hollywood hosted a virtual neighborhood meeting on June 10 to review the plans. Vanowen Management LLC's proposal is slated for a larger multifamily residential building than the duplex it replaces, per the planning report cited by Urbanize LA.
Part of a Bigger State-Mandated Push
The Sierra Bonita project fits into West Hollywood's 6th Cycle Regional Housing Needs Allocation, which covers 2021 through 2029, according to the Southern California Association of Governments.
West Hollywood's 6th Cycle Housing Element lays out how the city intends to meet that mandate. State density-bonus laws have also been discussed in connection with nearby Fairfax Avenue projects, as Hoodline covered in August.
While the demolition of the Hell House followed years of complaints, the Sierra Bonita proposal will likely become clearer as it advances through the city's planning process.
