Initial analysis

The duplex at 87-89 Collins Street is a two-story multi-family residential building constructed in 1949, containing two units and owned by Frank Mong & Sandra Lee 20. The property underwent significant renovations in 2008, with Unit 87 receiving a comprehensive kitchen and bathroom remodel including new tiles, cabinets, fixtures, and electrical work, costing approximately $29,000. The upper unit received updates to the master and children's bathrooms, along with front stairs repairs to meet Title 24 requirements. Additional improvements included the replacement of eight windows, kitchen remodels, powder room additions, and extensive electrical work throughout both units, with costs totaling over $60,000. During this renovation period, there was one building complaint filed on August 4, 2008, regarding work beyond the scope of the permit, though this was abated within a week.

More recent history shows several maintenance and utility updates, including the installation of two new furnaces in 2008 (60,000 BTU and 100,000 BTU) and the replacement of electrical panels and service equipment in 2004. The property has experienced some external maintenance issues in recent years, with several 311 calls in 2024 regarding a blocked sidewalk, garbage and debris, and sewer issues. The area has also faced recurring graffiti incidents between 2022-2024, primarily affecting street signs and a mailbox, though these have all been resolved. A general service request with the Bureau of Urban Forestry from June 2022 remains open. The building appears to have been well-maintained in terms of major systems, with comprehensive updates completed in 2008, though the recent maintenance issues suggest occasional challenges with external property upkeep.

Risk rating

How 87-89 Collins 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.
