Initial analysis

The property at 502-504 Shotwell Street is a 2-story, 4-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Constructed in 1909 and owned by Lee Kim Forn & Suk Man Chan, this apartment building has undergone several significant maintenance and compliance actions over the years. Most notably, in October 2003, the building received a series of fire safety and building code violations that required immediate attention, including issues with stairs, fire proofing, fire extinguishers, egress obstructions, and exterior door self-closing devices. These violations were all addressed and abated by November 2003, with repairs including the installation of redwood or treated wood stairs costing $2,000. The building underwent reroofing work in 1989, and a routine safety inspection was conducted in 2015, which revealed the need for a fire extinguisher date tag, though this issue was subsequently resolved.

More recently, the area immediately surrounding the building has experienced ongoing maintenance challenges, as evidenced by multiple 311 calls between January 6-12, 2025, primarily related to street cleaning and debris removal. These calls included reports of human waste, loose garbage, and yard waste, as well as one parking enforcement issue regarding a blocked driveway. There was also a fire alarm systems issue in February 2019 that was promptly corrected. While these recent complaints mostly pertain to street conditions rather than building-specific issues, they do indicate some ongoing environmental challenges in the immediate vicinity of the property.

Risk rating

How 502-504 Shotwell 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

Out of 2380 buildings in this neighborhood, 1261 are predicted to be safer.
