Initial analysis

The property at 333-335 Guerrero Street is a two-unit, two-story multi-family residential building located in the Mission Dolores neighborhood, owned by Tak Po Poon and Ming Wai Li. Built in 1940, this flats and duplex building has undergone several significant changes throughout its history. In 1992, a notable permit was processed to legalize a storage room and bathroom while removing an illegal basement unit, following earlier efforts in 1985 to address unauthorized alterations. More recently, the building's documented changes include a street space permit issued in 2019, though the nature and impact of this work are minimal given its nominal $1 cost.

The building's maintenance and resident experience have been impacted by various external factors, as evidenced by multiple 311 calls. Recent concerns from 2024 include reports of human waste and discarded needles on the street, indicating challenges with street maintenance and safety in the immediate vicinity. The property has also experienced recurring issues with garbage and debris on adjacent sidewalks, with documented cases in 2019 and 2020. Historical records show periodic graffiti incidents, including a 2021 incident on the sidewalk in front of the property and a 2009 case directly on the building, though these were resolved through standard city processes. A 2019 street cleaning issue and a parking enforcement matter in 2019 were also documented and subsequently addressed. While the building's structural modifications have been addressed through proper permitting and legalization processes, the surrounding street conditions have shown recurring maintenance challenges over the years.

Risk rating

How 333-335 Guerrero 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.
