Initial analysis

The two-unit residential building at 790-792 30th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1928, currently owned by Raymond K M Wong and Melina Y. The property has undergone several significant improvements over the past few decades, with the most substantial recent work occurring in 2018 when $32,000 was invested in replacing 1,100 square feet of siding, though notably not on the front facade of the building. Prior to this, there were attempted window replacement projects in 2015 and 2016, both of which were cancelled, with a later planning record from 2016 showing an approved replacement of 8 windows throughout the building's front, sides, and rear with aluminum wood clad windows.

The building has seen multiple interior improvements, particularly in 2006 and 2008, including cabinet and countertop installations in both units, with associated plumbing and electrical work completed for these renovations. A kitchen sink change was also completed in 2008, along with an electrical upgrade involving new circuits and receptacles on the second floor. The property has limited exterior issues on record, with only two 311 calls: one in 2019 regarding a parking violation that could not be validated, and another in 2017 concerning pavement defects that was transferred for attention. The building's maintenance history shows regular upkeep and improvements over time, with no recorded safety violations or significant resident complaints.

Risk rating

How 790-792 30Th 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
