Initial analysis

The two-unit residential building at 635-637 33rd Avenue in the Outer Richmond neighborhood is a 2-story flats and duplex structure built in 1925, currently owned by Leslie Howard Thaler. The property has undergone several significant renovations, with the most recent major work occurring in 2018 involving comprehensive updates to the third-floor unit's kitchen and bathrooms, along with furnace replacements for the second and third-floor units at a cost of $82,000. This project included extensive electrical and plumbing work, featuring new lighting, switches, receptacles, and modern kitchen appliances. The building has a documented history of improvements, including earlier renovations in 2006 to both bathrooms and kitchen updates in unit 635, electrical panel upgrades, and various system improvements. A notable incident occurred in 2017-2019 when there were allegations of illegal short-term rentals, which were subsequently resolved through the removal of listings from VRBO and Airbnb platforms, and appears to have been abated. The property has maintained most of its infrastructure, though there was an expired water heater permit from 2009, and a parking enforcement issue was reported and resolved in 2018. The building's maintenance history shows regular updates to essential systems, with no recorded safety violations or hazardous incidents, though there was a 2014 environmental health complaint that was transferred to the Health Department's Healthy Housing & Vector Control Program.

Risk rating

How 635-637 33Rd 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.
