Initial analysis

The property at 610-612 Oak Street is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1908 and currently owned by Yu Junying. The building has undergone several significant improvements over the past decades, with the most substantial renovations occurring between 2019-2020 when a comprehensive kitchen and bathroom remodel was completed ($35,000), including plumbing and electrical upgrades with a new 200-amp service installation. This renovation period also saw the installation of new laminate flooring and important foundation work through permeation grouting at substantial depths ($10,000).

The building's history reveals attention to structural integrity, with earlier attempts at foundation work in 2012 and 2010 (though these permits were withdrawn), and maintenance work such as reroofing in 1997-1998. A notable incident occurred in July 2019 when a building complaint was filed regarding possible construction without permits and concerns about a potential illegal unit, though this complaint is currently listed as "Not Active." Most recently, in September 2024, there was a report of a damaged side sewer vent cover that remains open and accepted with the Public Works agency. Additional historical records show past improvements including deck replacements in 1990 and a horizontal addition in 1989, though some proposed rear deck additions were disapproved in planning records.

Risk rating

How 610-612 Oak St'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
88th percentile

Out of 1027 buildings in this neighborhood, 123 are predicted to be safer.
