Initial analysis

The two-unit residential property at 2636-2638 3rd Street, owned by the Mercedes S Gardner Living Trust, is a two-story flats and duplex building constructed in 1900. The building history includes a significant fire repair project completed in 1984 that addressed damages to the lower unit's bedrooms, kitchen, and bathroom. A notable infrastructure issue emerged in January 2022, when a complaint was filed regarding gray water drainage problems from unit 2638, which reportedly affected the neighboring property at 2642 3rd Street, though this complaint is currently listed as not active.

The most recent building activity, from late 2024, shows multiple instances of garbage and debris issues recorded through 311 calls, with several reports of human waste or urine on the nearby streets and sidewalks, as well as complaints regarding general garbage conditions. The property has experienced two fire-related incidents in the recent past: an unintentional alarm system activation and a welfare check, neither resulting in civilian injuries. Additionally, there are currently two open fire violations recorded at a different address (401-601 23rd Street), related to sprinkler system maintenance and a general permit issue, both dated July 14, 2020.

Risk rating

How 2636-2638 3Rd 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

Out of 74 buildings in this neighborhood, 57 are predicted to be safer.
