Initial analysis

The two-unit residential building at 641-643 Central Avenue in the Park North neighborhood, owned by Anita Lee, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations over the past few years, with the most recent major work including reroofing in February 2023 ($12,000) and sheetrock replacement with electrical upgrades in basement storage rooms (February 2023, $3,000). A more extensive renovation occurred in 2021-2022, involving remodeling of kitchen and bathroom facilities, new flooring, and electrical work ($36,800). Previous improvements include a kitchen and bathroom renovation in 2008 ($20,000), and structural repairs to address dry rot issues in 1992.

The building's recent history has been marked by some concerning events, particularly during the 2023 roofing work, when there were multiple reports of dangerous construction practices, including debris being thrown from the roof which damaged power lines and caused electrical sparks, and complaints about work being done without proper permits. There was also a complaint in 2016 regarding improper containment of painting debris. The property has experienced recurring issues with street cleaning and waste management in the immediate vicinity, with multiple 311 calls between 2020 and 2023 reporting problems with loose garbage, illegal postings, and waste. While many of these neighborhood issues have been resolved according to city records, they indicate ongoing challenges with property maintenance and surrounding area upkeep. The building's permit history suggests regular maintenance and upgrading of facilities, though some recent work has raised safety and compliance concerns.

Risk rating

How 641-643 Central 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

Out of 797 buildings in this neighborhood, 367 are predicted to be safer.
