Initial analysis

The 4-unit multi-family residential building at 2501-2507 Balboa Street, owned by the Chi Mui Mok Trust, was constructed in 1921 and has undergone several significant renovations over its history. Most notably, in 2009, comprehensive improvements were made including kitchen and bathroom remodels in multiple units, installation of new plumbing systems, electrical updates with new smoke detectors, and the conversion of a dining room into a bedroom with corresponding bathroom modifications, with a total cost of approximately $20,500. The building experienced a serious fire safety incident in 2004 when violations were recorded concerning egress obstructions and combustible storage, though these were resolved within two months. Earlier maintenance work included termite repair in 1996 and rear stair repairs in 1989, demonstrating attention to structural upkeep.

Recent concerns include multiple sewage backup incidents in January 2025, with documented issues from the side sewer vent that required municipal intervention. The property has also been the subject of numerous parking-related complaints in late 2024, particularly regarding illegal parking and driveway blocking, with several citations issued. Historical records indicate a gas leak incident and a false fire alarm, neither resulting in civilian injuries. The building has maintained its residential character throughout its history, with a recent commercial tenant improvement application in 2023 that did not alter the building's facade or use. While the property has had its share of maintenance and compliance issues, recent upgrades and repairs suggest ongoing attention to building maintenance, though the recent sewer issues may indicate potential infrastructure concerns.

Risk rating

How 2501-2507 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.
