Initial analysis

The Chow Family Trust owns this two-story, three-unit multi-family residential building located at 747-749 Webster St in Alamo Square, which was constructed in 1890. The property has experienced recurring issues with staircase maintenance and safety compliance, most notably evident in multiple repairs to the front stairs between 2008 and 2018, including a significant $8,000 renovation in 2018 to address dry rot. The building has undergone several major improvements, including reroofing in 2005 ($8,900) and addressing various dry rot issues as early as 1989. A notable cluster of code violations and complaints was documented in 2011, including issues with fire extinguishers, smoke detectors, wood stairs, electrical outlets, security features, and handrails, though these were all abated by November 2011.

The building is currently under routine safety inspection by Housing Inspection Services as of October 2018. Recent maintenance and emergency incidents have been primarily external to the building, including fallen trees and sidewalk issues noted in 2024. A fire hazard complaint was investigated in October 2023 but was found to have no merit. The property has maintained active compliance with building codes since 2011, with no significant internal issues reported in recent years. Recent 311 calls have primarily concerned exterior matters such as street maintenance and urban forestry issues, rather than building-specific concerns. Two notable historical violations were recorded: one for electrical work in 2009 and another for unpermitted alterations to the second-story balcony and storefront, though the latter was subsequently abated.

Risk rating

How 747-749 Webster 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.
