274 12th Ave, San Francisco, CA 94118

274 12th Avenue is a 6-unit, 3-story multi-family residential building constructed in 1959 in the Inner Richmond neighborhood, currently owned by Lily C Sathienthirakul Revo. The building has undergone several significant safety improvements in recent years, most notably a seismic retrofit in 2015 that included the installation of moment frames and plywood shear walls to address its Tier 3 soft-story designation. Other major completed work includes the replacement of wood siding with handi plank siding in 2018, installation of a new water heater and roof drain pipe in 2018, and the addition of a fire sprinkler under-stair system in 2011.

The building experienced multiple maintenance issues in 2018, with complaints regarding heating systems, water quality, plumbing problems, and safety concerns including a dangerous roof opening. These issues were addressed through subsequent permits and inspections. The building's history includes several regulatory interactions, including a cluster of fire safety violations in October 2000 related to smoke enclosure doors, fire proofing, combustible storage, and egress obstructions, all of which were resolved by January 2001.

More recent violations in 2017 required the installation of carbon monoxide detectors and resolution of inspection access issues. The property has undergone regular housing inspections, with all routine inspections being marked as "Not Active" following their completion. Recent repair and improvement history demonstrates ongoing maintenance and safety compliance efforts, though several HVAC and plumbing issues were reported in 2018 that required multiple permits to resolve. The building's single recorded fire incident involved a water or steam leak, and there was one documented instance of offensive graffiti in 2011.
