Initial analysis

The three-story, four-unit multi-family residential building located at 115-121 30th Street in Glen Park, owned by Omar D Ulloa Revocable Trust, has been standing since 1910. The property has undergone several significant structural and maintenance work between 1994-1998, including a complete reroofing in 1994 and substantial repairs for dry rot in the ground-level joists, stairs, and corners in 1995. The building underwent an inspection in 1996 regarding unauthorized rental of a garage space without proper facilities, though this issue was resolved by July 1996. A notable modification occurred in 1998 when one bedroom was reclassified as non-habitable, and there have been multiple routine housing inspections conducted between 1997 and 2007, with the most recent routine inspections from 1997 showing as active status.

The property has experienced various maintenance and safety-related issues in the surrounding area in recent years. Most notably, there are current open issues from 2024 including excessive noise and pavement defects. A pattern of parking-related complaints has emerged in 2024, with multiple reports of illegal parking and blocked bicycle lanes, though these have mostly been resolved through enforcement actions. The surrounding area has experienced recurring cleanliness issues, with reports of garbage, waste, and an overflowing city garbage can being resolved through municipal services between 2021 and 2024. While these external issues don't directly impact building safety, they do affect the overall environment around the property. The building's documented history shows consistent attention to structural maintenance and compliance with housing inspections over its long history, with most historical permits and complaints having been properly resolved.

Risk rating

How 115-121 30Th 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
26th percentile

Out of 364 buildings in this neighborhood, 269 are predicted to be safer.
