Initial analysis

The two-unit duplex at 66 States Street in Corona Heights, owned by Michael Chia-jun Weng, was constructed in 1976 and has experienced several notable issues over its recorded history. The building's most recent maintenance activity on record was a reroofing project from 1991, though the permit for this work has since expired. The property has faced various maintenance and public safety challenges, particularly in recent years, including an unresolved backyard debris complaint from 2014 and an open sidewalk defect case from 2019 related to tree root lifting. There was a significant sewer issue on the property in December 2021, although this was eventually resolved. The building's surroundings have experienced numerous municipal service calls, including multiple reports of debris (most recently in September 2024), flooding, graffiti (including an offensive incident in 2020), illegal postings, and pavement defects.

The surrounding area has undergone various changes in recent years, with two notable tenant buyouts occurring nearby: a $30,000 buyout involving three tenants at 62 States Street in September 2020, and a $40,000 buyout involving two tenants at 3775 16th Street in August 2015. Public infrastructure issues have been a recurring theme in the vicinity, with multiple cases reported to the Department of Public Works, including concerns about sidewalk and pavement conditions, while reports of illegal postings and encampments have also been documented and addressed through official channels.

Risk rating

How 66 States 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
