Initial analysis

The three-unit, two-story multi-family residential building at 2730 Franklin St in Cow Hollow, owned by Peter S. and Helen K. Lam, has undergone several significant improvements since its construction in 1951. Most recently, in May 2023, the building completed a window replacement project valued at $12,000, installing aluminum bronze windows with energy-efficient specifications. Between 2008 and 2021, the property has seen multiple unit-specific renovations, including kitchen remodels in Units 1 and 2, with the most recent renovation in Unit 1 occurring in 2021 (valued at $5,000). The building's maintenance history shows attention to infrastructure, with a complete reroofing project completed in 2009 for $6,000.

The property has experienced several fire safety and security issues, particularly evident in a routine inspection in February 2002 that identified multiple violations, including fire safety concerns, egress obstructions, and security deficiencies such as the need for proper deadlatch locks on exit doors. While these violations were abated by March 2002, the building's records from 1987 show expired compliance requirements from the Department of Health Administration and an attempted sprinkler installation in 1984 that was cancelled. More recent building maintenance has focused on improvements rather than compliance issues, with no active violations since the 2002-2008 period. The property has experienced recurring issues with blocked driveways and street cleaning concerns, as evidenced by multiple 311 calls between 2020 and 2024, though these relate to street conditions rather than building-specific issues.

Risk rating

How 2730 Franklin 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
75th percentile

Out of 861 buildings in this neighborhood, 215 are predicted to be safer.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
