Initial analysis

The three-unit multi-family residential building at 89 Homestead Street in Noe Valley, owned by William J & Josephine A Lyn, was constructed in 1993 following the demolition of a single-family dwelling in 1992. The two-story flats and duplex structure has undergone several significant improvements over its lifetime, including a substantial $60,000 window upgrade in 2007 that involved replacing 44 aluminum windows with aluminum cladwood windows and repairing siding and trim as needed. In recent years, the building has seen maintenance of its plumbing system, with the installation of two backflow preventers on hydronic boilers in April 2015 representing the most recent major infrastructure upgrade.

The property has experienced some environmental and infrastructure challenges in recent years, with ongoing concerns about trees affecting the building's exterior, including an open tree maintenance case from January 2025 regarding damage to windows or the building, and a sidewalk defect case from August 2024 involving lifted sidewalk issues caused by tree roots. The building's immediate vicinity has faced recurring parking enforcement issues, with multiple cases of blocked driveways and illegal parking reported between March 2024 and February 2025, though enforcement officers were often unable to locate the offending vehicles. The most recent building permit activity includes two street space permits issued in 2014 and 2019, though these represent minimal financial impact at $1.00 each.

Risk rating

How 89 Homestead 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.
