Initial analysis

The 52 Page Street building, located in Hayes Valley, is a 4-story multi-family residential structure containing 8 units, built in 1907 and currently owned by Lawrence Wong 2015 Trust. The property has undergone several significant renovations and improvements over the years, with the most substantial work completed in 2017 involving a mandatory seismic retrofit of the soft-story structure, classified as Tier 3, with work now marked complete and receiving a Certificate of Final Completion (CFC). The building suffered fire damage in 2007 that required extensive repairs, including roof replacement, wall repairs, and installation of safety features like shear walls and foundation bolts, costing approximately $300,000. Subsequent to this event, major systems upgrades were performed including a fire alarm system retrofit in 2009 ($14,000), complete electrical rework including a new 400-amp service installation, and plumbing upgrades including the installation of 8 new gas furnaces.

The property has experienced recurring fire safety issues, with multiple Fire Code Violations documented in 2023 and 2019, and several fire-related incidents including alarm system malfunctions and cooking fires, though none resulted in injuries. There were also three fire violation cases between 2019 and 2023 related to alarm system maintenance, documentation, and sprinkler system issues, all of which have been abated. Earlier in its history, the building faced various maintenance challenges including water damage and mold issues in 2005-2006, lead paint concerns in 2006, and multiple complaints about construction-related disturbances in 2008. The building has undergone significant system improvements including the installation of backflow devices (2016), comprehensive electrical system updates (2008), and various plumbing improvements. Most notably, the building completed all requirements of San Francisco's mandatory seismic retrofit program and achieved compliance with the Maher Ordinance requirements.

Risk rating

How 52 Page St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
