Initial analysis

The 4-unit, 2-story multi-family residential building at 1243-1253 Judah Street in the Inner Sunset, owned by Kevin W. and Norman W. Leong, was constructed in 1922 and has undergone several significant maintenance and repair projects over the years. Most notably, the property experienced a vehicle collision with the eastside garage door in September 2023, resulting in stucco damage and structural concerns that required immediate attention. This incident triggered a series of building permits and repairs throughout 2024, including the replacement and repair of stucco walls, with work continuing into October 2024 under permits valued at $6,000 and $4,500 respectively.

The building has a documented history of various improvements and maintenance work, including plumbing upgrades with the replacement of two furnaces in 2019, electrical system improvements in 2003 featuring a 150-amp service upgrade and unit-specific installations, and earlier exterior work such as vinyl siding installation in the 1990s. In 2018, the property faced multiple housing-related complaints regarding hot water issues, mold, and asbestos concerns in the kitchen, though these cases were ultimately marked as not active. More recently, there have been numerous 311 calls recorded in 2024 primarily related to street issues such as graffiti, garbage, and parking concerns, though these are external to the building itself.

Risk rating

How 1243-1253 Judah 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
