427 18th Ave, San Francisco, CA 94121

The 12-unit, 3-story apartment building at 427 18th Avenue in the Central Richmond neighborhood, owned by the J A D 1996 Revocable Trust, has undergone significant improvements since its 1927 construction. The property completed a mandatory soft-story retrofit in 2016, achieving compliance with Tier 3 requirements by installing steel frames, plywood shearwalls, and reinforced concrete grade beams at the garage level.

Recent major improvements include a sewer and house trap replacement in 2022, and various internal renovations in 2019 involving sheetrock installation, flooring updates, and cabinet work valued at $18,000. The building's fire safety systems have experienced multiple false alarms since 2013, with the most recent incident in September 2023 being resolved promptly. Historical violations primarily from 2000 have been addressed, including electrical issues, security requirements, and fire safety concerns, with no active violations on record.

The illegal unit situation reported in 2012 appears to have been resolved, as building permits from 2018 indicate legalization efforts including fire separation and sprinkler system installation for a ground-floor unit. Recent maintenance issues have included several 311 calls in 2024 regarding garbage debris, tree maintenance, and public works matters, though these have been generally promptly addressed. The building's plumbing and electrical systems have received significant attention, with multiple permits showing systematic improvements, including gas line rerouting and electrical rewiring related to seismic retrofit work.
