Initial analysis

The two-unit, two-story multi-family residential building at 121 2nd Avenue, located in the Lake-Presidio neighborhood and built in 1907, has undergone several significant renovations and faced various maintenance issues over its history. The most recent work, scheduled for 2024, involves re-roofing the building at a cost of $15,000, marking the property's first major work in nearly a decade. Notable improvements occurred in 1996 when substantial renovations were completed, including foundation repairs, vertical modifications, and the enlargement of the kitchen and bathroom spaces. The building was originally converted to create two units in 1990, following earlier alterations in 1987 involving the installation of new partitions and fixtures.

The property has experienced several maintenance challenges, particularly with its infrastructure. There was a sewage backup issue reported in 2014 that was resolved, and multiple sidewalk defects were documented in 2012, requiring attention to 80 square feet of damaged sidewalk. A concerning pattern of illegal short-term rental activity was reported between 2016-2018, though this violation has since been closed and abated. Recent external incidents include a January 2024 parking violation involving a vehicle on the sidewalk and a December 2022 report of medical waste (needles) in the vicinity, both of which were addressed by city services. While the building has required various repairs and updates over the years, most significant improvements, such as the 2024 roof work and past structural modifications, suggest ongoing maintenance attention from the owners.

Risk rating

How 121 2Nd Ave'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 660 buildings in this neighborhood, 86 are predicted to be safer.
