Initial analysis

The property at 1251-1253 41st Avenue in the Outer Sunset is a 2-unit residential building constructed in 1981, currently owned by the Tom Family Living Trust. The two-story building has undergone several significant maintenance and repair projects over its lifetime, most notably recurring roof work, with the most recent reroofing project costing $10,000 in 2022, following a larger $14,000 reroofing project in 2021. A substantial renovation took place in 2007 when the building received new front stucco siding on the second and third floors to address previous waterproofing and water penetration issues, along with the installation of 12 new dual-glazed windows, a project that cost $18,000.

The property has experienced various maintenance and inspection issues in recent years, with the most recent concerns emerging in October 2024 including plumbing-related incidents and an environmental health request, though one plumbing complaint was deemed invalid. Historical issues worth noting include a sewage backup incident in early 2020 and several parking enforcement matters related to sidewalk parking in 2020 and 2021, both of which resulted in citations. The building's maintenance record shows attention to basic upkeep, particularly regarding the roof, which has required multiple replacements over the past decades, with the earliest roofing permit dating back to 1995. There have also been periodic interactions with city services for various matters, including a rent board mailing request in early 2022 and general cleaning issues in 2021 that were resolved.

Risk rating

How 1251-1253 41St 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 632 buildings in this neighborhood, 82 are predicted to be safer.
