285 27th Ave, San Francisco, CA 94121

The 6-unit, 2-story multi-family residential building at 285 27th Avenue in Sea Cliff, owned by Dennis Hoo, has undergone several significant structural improvements since its 1960 construction. Most notably, the building completed mandatory seismic retrofitting in 2014 as a Tier 3 soft-story property, including foundation reinforcement and new steel strong walls at both front and rear openings.

In 2024, the building underwent substantial repairs related to wood rot issues, with multiple permits issued for work including beam and sill plate replacement ($15,000), exterior dry rot remediation ($15,000), and stucco/window replacement investigations ($5,000). Earlier major work in 2003 involved sheathing replacement and window upgrades. The building's maintenance history shows attention to safety and structural integrity, though there were some fire safety violations recorded in 2003 regarding fire escape ladders and combustible storage, all of which were promptly addressed by December 2003.

The most recent permits from 2024 indicate continued proactive maintenance, with specific attention to addressing wood rot issues. The property has undergone routine housing inspections in 2003, 2008, and 2010, all of which were resolved. There have been multiple 311 calls regarding street cleaning matters between 2020 and 2023, primarily related to loose garbage and holiday tree removal, though these appear to be routine municipal service calls rather than building-specific issues.
