Initial analysis

The two-unit residential building at 9-11 Carl Street, owned by the Thorina H Rose Living Trust, is a two-story flats and duplex structure built in 1908 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant maintenance and safety improvements in recent years, most notably a comprehensive rear renovation in 2021 that included the replacement of rear siding (450 square feet), installation of 12 new rear windows, repair of dry rot in framing, and replacement of a non-conforming rear stair, totaling approximately $43,000 in improvements. A previous attempt to address stair safety issues in 2020 and 2012 was withdrawn, highlighting the importance of these completed renovations. The building's systems were updated in 2013 with the installation of a new York furnace.

The property has experienced several parking-related issues in recent years, with multiple complaints about driveway blocking between 2023 and 2024, though responders were often unable to locate the offending vehicles. There have been minor neighborhood maintenance issues recorded, including a defaced parking sign in 2019, two resolved cases of graffiti and illegal postings in 2013, and a sidewalk defect due to tree roots documented in 2010. Historical records show various interior improvements from 1997-2002, including bathroom fixture replacements, pantry modifications, and kitchen renovations, indicating regular maintenance of the unit interiors over the years. The building's recent permit history demonstrates significant attention to safety compliance and structural maintenance, particularly regarding egress requirements.

Risk rating

How 9-11 Carl 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.

Neighborhood percentile
99th percentile

Out of 526 buildings in this neighborhood, 5 are predicted to be safer.

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

Property class: single-family home

Moderate concern 5.1%
Severe concern 1.7%
