Initial analysis

The Chestnut Street property at 727-731 is a three-story, 10-unit multi-family residential building located in Russian Hill, built in 1912 and currently owned by Leslie Lum. The building has undergone several significant renovations in recent years, most notably in 2022 when units 727 and 731A received comprehensive remodeling including kitchen and bathroom updates, window replacements, and electrical system upgrades, costing approximately $60,000. These renovations followed a series of complaints in 2022 regarding construction work being performed without proper permits, excessive noise, and temporary hot water shutdowns. Prior to this, Unit 729B underwent window installation in 2010, which was properly permitted and included the installation of seven vinyl windows with modern energy efficiency features.

The building has experienced various maintenance and safety concerns over the years, with several violations documented in 2010 regarding lead paint hazards, interior surface conditions, and building sanitation issues, though these were abated by December 2010. A cluster of housing code violations was recorded in 2005, including issues with fire extinguishers, wood stairs, and smoke detection systems, all of which were also resolved. More recent complaints in 2023 related to fire safety equipment were found to have "No Merit" or were "Condition Corrected." The property has maintained an active response to building maintenance needs, as evidenced by multiple completed permits for plumbing, electrical, and general repairs throughout the years. Recent 311 calls from 2023-2024 primarily relate to street cleaning, sidewalk maintenance, and external issues rather than building-specific concerns, suggesting improved property upkeep in recent years.

Risk rating

How 727-731 Chestnut 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.
