Initial analysis

The property at 401 30th Street in Glen Park is a 2-story, 5-unit multi-family residential building constructed in 1927, currently owned by the Horwitz Marital Trust. The building has undergone several significant improvements and meets current safety standards, including completed soft-story retrofit work (Tier 3) in 2014 at a cost of $125,000, which was required under San Francisco's mandatory seismic safety program. Most recently, in 2021, there was a filed permit to convert ground floor garage and storage spaces into accessory dwelling units, along with facade improvements including new windows and doors, though this permit's current status needs confirmation.

The building has a history of maintaining compliance with safety regulations, with all violations from a 2008 inspection being promptly addressed within one month, including issues related to fire extinguishers, smoke detectors, and ceiling repairs. Earlier maintenance work includes a complete reroofing in 2013 and water service replacement at the meter. While there have been several 311 calls regarding the property in recent years (2022-2025), these primarily relate to external issues such as parking, tree maintenance, and illegal postings, rather than building-specific concerns. The property has demonstrated regular upkeep and responsiveness to violations, with no active complaints or violations currently on record.

Risk rating

How 401 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.
