Initial analysis

The three-story multi-family residential building at 2921 Octavia Street in Cow Hollow, owned by Calvin Philip & Murphy Shar, was constructed in 1880 and contains two units. The property underwent significant renovations in 2000, including a $150,000 renovation of the two-unit building and new garage construction, followed by various modifications to the roof deck, railings, and foundation plans. Most recently, in August 2020, the building received substantial maintenance work valued at $40,000 to address dry rot issues on both the front and rear decks, along with window and door replacements using "Milgard Tuscany Vinyl Series" products. A linear deck drain was installed in January 2021, and a gas insert was added in December 2019.

The building's maintenance history shows regular upkeep, though there have been some tenant-related issues such as an unauthorized satellite dish installation in 2005 and two recent instances of driveway blocking in September 2024. The property has experienced various infrastructure-related incidents typical for its age and location, including a water leak (2013), damaged tree (2017), and streetlight outage (2012), all of which were resolved through appropriate channels. While the garage door opener installation permit from 2004 shows as expired, this is likely a clerical issue as the work would have been completed during that period. The most recent building maintenance work, completed in 2020, demonstrates ongoing attention to structural integrity and resident comfort.

Risk rating

How 2921 Octavia 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.
