Initial analysis

The 15-unit apartment building at 740 Parnassus Ave, owned by Manfred & Sheila C Angstenb, is a three-story multi-family residential structure built in 1926. The property has undergone several significant improvements and faced multiple maintenance challenges over the years. Most notably, the building completed mandatory soft-story seismic retrofitting in 2015, demonstrating compliance with San Francisco's safety requirements. Recent improvements include a reroofing project in 2017 ($28,000), brick facade repairs in 2017 ($18,000), and the replacement of 80 vinyl windows in 2013. The building is currently undergoing fire alarm system upgrades to add new sounders for improved safety compliance, with permits filed in November 2024.

The property has experienced various maintenance issues, including hot water problems in late 2018, unauthorized furnace replacement in 2019, and some work performed without proper permits in multiple units. There have been several routine inspections and violations, particularly in 2003 and 2006, related to fire safety requirements and unauthorized modifications, though these issues were subsequently addressed. Building systems have received attention over the years, with the main water pipe replaced from the meter to the building in 2022 and various unit-specific renovations completed between 2013-2019. The building has experienced multiple false alarm activations and system malfunctions, but no actual fire incidents have been reported. A sidewalk defect was reported in October 2024, which remains open as of the latest information.

Risk rating

How 740 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.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 1403 are predicted to be safer.
