Initial analysis

The 4-unit, 2-story multi-family residential building at 106-110 Woolsey Street in the Portola neighborhood, owned by John Richard Saisi, was constructed in 1941 and has undergone several maintenance and compliance updates over the years. Most recently, in early 2024, plumbing work was completed for refrigerator condensation and gas houseline extensions. The property has experienced periodic inspections and maintenance issues, with notable violations recorded in 2001 (security/door issues), 2004 (identification and handrail problems), and 2008 (fire safety concerns), though all these violations were subsequently abated within reasonable timeframes. Historical permits show garage door replacements in 2016 and reroofing work from 1993, while planning records indicate a Type 21 ABC referral for 106 Woolsey Street.

The building's maintenance records suggest ongoing attention to necessary repairs and upgrades, though there have been some recurring issues with parking enforcement in recent months, with multiple reports of driveway blocking between October 2024 and January 2025, totaling at least seven such complaints. Additionally, there have been several instances of street cleaning requests for garbage and debris removal in late 2024, though most were resolved quickly. The property's plumbing infrastructure has received particular attention in recent years, with work completed or initiated on multiple systems including gas lines and refrigerator equipment. The most recent building permit activity, from 2016, indicates work consistent with maintaining the property's infrastructure.

Risk rating

How 106-110 Woolsey 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.
