Initial analysis

The two-unit, 2-story multi-family residential building at 734-736 9th Avenue in the Inner Richmond, owned by Victor M. Quan, was constructed in 1913 and has undergone several significant renovations and repairs over the past decade. The most recent major improvement was the installation of a 5.7 kW solar panel system in 2022, demonstrating a commitment to energy efficiency. In 2016-2017, substantial remodeling work was completed including kitchen and bathroom renovations on all floors, new windows installation, and various plumbing and electrical upgrades with a reported cost of $180,000. However, this renovation period was marked by multiple complaints regarding construction debris containment and potential lead paint disturbance.

The building has experienced some maintenance issues, notably requiring dry rot repairs to front bay windows in 2017, with costs exceeding $5,000. Of particular concern was a period in 2015 when the property was designated as a vacant building, resulting in multiple notifications and violations related to the Vacant Building Ordinance, though these were abated by June 2015. The property's infrastructure has seen significant upgrades, including a complete electrical rewiring and new 200-amp main service with three meters in 2017, and a comprehensive plumbing modernization including radiant heating and new systems for kitchens and bathrooms. A carbon monoxide incident was recorded with no civilian injuries, though the date and specific details were not provided in the available data.

Risk rating

How 734-736 9Th 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.
