Initial analysis

The 9-unit, 3-story multi-family residential building at 170 Parnassus Ave, owned by Devpac LLC and constructed in 1924, has demonstrated proactive maintenance and safety compliance over recent years. Most notably, the building completed its mandatory soft-story retrofit in 2017 with a cost of $100,000, achieving Tier 3 status with Certificate of Final Completion issued. Significant improvements include a $20,000 stairway support repair and storage area improvements in 2019, a complete fire alarm system replacement in 2015, and various street space permits issued between 2017-2019. The building has undergone regular routine inspections, with a cluster of violations in 2003 related to fire safety and security that were promptly addressed by February 2003, including fire escape maintenance, fire proofing repairs, and installation of proper locks. While there have been multiple fire alarm system-related incidents and complaints throughout the years, all were determined to be malfunctions with no civilian injuries reported. More recently, there have been recurring issues with driveway blocking, as evidenced by multiple parking enforcement calls between 2022 and 2024, suggesting ongoing challenges with access to the property. The building's maintenance record shows consistent attention to safety requirements, with all known violations being resolved in a timely manner.

Risk rating

How 170 Parnassus Ave'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.
