Initial analysis

The Cheng Family Trust owns this 3-unit, 3-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, which was constructed in 1911. The property has undergone significant modifications and faced several challenges over the past few years. Most notably, in 2018, substantial horizontal expansions were permitted across multiple levels, including garage/storage areas and residential units, adding a total of 6 new bedrooms and multiple bathrooms, with an investment of $525,000. A serious incident occurred in 2017 when the building suffered moderate fire and water damage, particularly impacting Unit 1326, which required extensive repairs including ceiling and wall reconstruction, with electrical rewiring completed under a separate permit.

Recent concerns focus on excavation activities that began in October 2024, with reports of unsafe conditions involving removal of internal support from neighboring properties and yards, creating a slope cut up to 6 feet deep. This triggered a building violation citing potential safety hazards. Historical records show routine inspections in 2001 and 2011, with the 2011 inspection addressing the replacement of exterior emergency exit steps at the rear due to age. The building has experienced various maintenance and compliance issues over the years, including a 2022 violation for debris in the backyard (though this was abated in January 2023). There have been multiple 311 calls regarding sidewalk blockage and abandoned vehicles near the property between 2017 and 2024, as well as reports of hazardous materials and medical waste in the vicinity.

Risk rating

How 1324-1328 12Th Ave'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.
