Initial analysis

The three-story multi-family residential building at 2100-2104 Larkin Street in Russian Hill, built in 1910 and containing 6 units, has undergone significant recent renovations totaling over $215,000 in 2019-2020. These improvements included comprehensive kitchen remodels in multiple units (completed June 2019) and bathroom renovations in both buildings (completed May 2019), along with electrical upgrades such as new lighting and receptacles. In early 2020, the building underwent HVAC system upgrades with furnace replacements across units, though some associated permits expired without proper completion notice.

The property has had several routine housing inspections over the years, with a notable cluster of violations documented in August 2001 related to gas meter safety requirements and stair repairs, though all these violations were promptly abated by September 2001. While there was a documented smoke scare incident (date unspecified, no injuries reported), this appears to be the only fire-related event on record. Recent history shows numerous 311 calls between 2023-2025 primarily concerning parking issues and street maintenance matters near the building, including multiple reports of illegal parking and sidewalk cleaning requests. The most recent building improvements suggest active maintenance of the property, though the presence of multiple expired permits from early 2020 regarding furnace replacements raises some questions about the completeness of that particular upgrade process.

Risk rating

How 2100-2104 Larkin 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.
