Initial analysis

The 6-unit apartment building at 741 Balboa St in San Francisco's Inner Richmond district is a three-story multi-family residential structure built in 1927 and currently owned by the Chin Wai Seung Revocable Trust. The building has undergone several significant safety upgrades in recent years, most notably in 2022 when the fire alarm system was improved to comply with San Francisco Fire Code requirements, including the installation of low-frequency sounders in sleeping areas to meet the 75dB at pillow standard. This $15,000 upgrade demonstrated the owner's commitment to maintaining fire safety standards, especially following a fire-related violation in 2000 regarding combustible storage that was promptly addressed within two months through installation of automatic sprinklers.

The building's maintenance history shows regular upkeep of critical infrastructure, including two reroofing projects completed in 1991 and 2006, costing $7,200. The property has undergone routine housing inspections in 2000 and 2015, though no significant ongoing violations were recorded. Recent parking enforcement calls related to driveway blockage in 2021 and 2024 suggest occasional neighborhood parking challenges, though these are not directly related to the building's condition or management. The most recent building permits and safety upgrades indicate active management of the property's systems and compliance with current safety requirements, particularly regarding fire safety improvements.

Risk rating

How 741 Balboa 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.

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
