Initial analysis

The two-unit residential building at 547-549 17th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1921, currently owned by the Kwok Esther Revocable Living Trust. The property has undergone several significant improvements over the past decades, with particular emphasis on modernization and sustainability. Most notably, in 2021, a 22kW emergency generator with a 200 amp automatic transfer switch was professionally installed on the rooftop, providing reliable backup power and consistent with a prior 1996 permit for generator installation. The electrical system has been routinely upgraded, including a 100-amp service upgrade in 2012 and the addition of a solar panel system featuring six roof-mounted PV modules with a total rating of 1.41kW.

Recent building enhancements focus on window improvements, with two separate permits filed in June 2022 for the replacement of street-visible windows with energy-efficient reclaimed wood composite frames, though these permits currently show a "Filed" status. The building's maintenance record shows attention to exterior improvements, including a 1996 permit for vinyl siding installation on the back side of the house, though this permit has since expired. Infrastructure maintenance issues have been minimal, with only two pavement defect complaints reported on 10/11/2015 and 10/13/2015, both of which were resolved by city agencies. A parking enforcement call regarding sidewalk obstruction was received in January 2025, but the responding officer was unable to locate the offending vehicle.

Risk rating

How 547-549 17Th 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
