Initial analysis

The two-unit residential building at 18-20 Auburn Street in Nob Hill is a two-story flats and duplex structure built in 1924, currently owned by Richard & Sally Leong Family. The property underwent significant renovations in 2012-2013, with improvements totaling $65,000 including new kitchen and bathroom fixtures, cabinets, floor/wall tiles, window replacements, and electrical upgrades. The comprehensive renovation project also involved major infrastructure updates including the installation of two furnaces, complete bathroom and kitchen renovations, new fireplace inserts, modern electrical systems including multiple lights, switches, and appliance installations, and comprehensive plumbing work including new water pipes from the meter to the units.

The most pressing recent issues at the property relate to sidewalk parking violations, with eight recorded incidents of vehicles parking on sidewalks between August and January 2025, though enforcement officers were often unable to locate the offending vehicles. Additionally, there have been several recent cases of garbage and debris on or near the property, including reports of human waste, though most were resolved without requiring interventions. The building's maintenance record shows historical work including reroofing in 1992, indicating ongoing care of the property's infrastructure. The extensive 2012-2013 renovations suggest a significant modernization of the building, though the recent pattern of sidewalk parking violations and street cleaning issues may warrant attention to local enforcement practices in the area.

Risk rating

How 18-20 Auburn 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.
