Initial analysis

The two-unit multi-family residential building at 647-649 18th Avenue in the Central Richmond neighborhood, owned by Jasmine Yee Hing Leung, has undergone several significant renovations since its construction in 1923. The most extensive work occurred between 2007-2009, when the property underwent a major transformation including the merging of second and third-floor units into a single unit, creation of a new ground-floor unit, and substantial horizontal additions. This renovation period also saw complete rewiring of the building, installation of new electrical systems (including 50 lights, 20 switches, and 60 receptacles), bathroom and kitchen remodeling, and the addition of an exercise room, half bath, and storage space. During this same period, the building received upgraded heating systems with the installation of three new furnaces and one fireplace.

The building's infrastructure improvements continued in 2008 with modifications to the second-floor exterior deck and roof deck, though these changes were relatively minor. Historical records from 1994 indicate earlier maintenance work, including deck repairs for dry rot and window replacements, suggesting ongoing attention to building upkeep. The extensive renovations completed between 2007-2009, including the addition of two bathrooms on the third floor and garage modifications, represent the most significant period of improvement in the building's recent history. All major permit work from this period has been completed, though one permit from 2007 related to merging front entry doors is noted as "Filed."

Risk rating

How 647-649 18Th 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.
