The two-unit residential building at 907-909 Clayton Street, located in the Parnassus/Ashbury Heights neighborhood, is a two-story flats and duplex structure built in 1906 and currently owned by the Bertram Family Trust B. The property has a documented history of stair-related maintenance issues, with repairs to exterior stairs and landings occurring in 2014, 2006, and as far back as 1989. A significant cluster of building violations was recorded in 2006, including issues with stairs, security features (deadlatch locks and self-closing doors), and a fire safety concerns, all of which were addressed by March 2007. Another set of violations was documented in 2011 regarding lead paint, fire extinguisher maintenance, and gas meter instructions, which were promptly resolved within two months.

In terms of building maintenance, a roof replacement was undertaken in 2008 at a cost of $14,750, and various stair repairs have been completed over the years. Recent activity near the property has primarily consisted of parking enforcement matters, with multiple reports of driveway blocking incidents in late 2024, though enforcement officers were often unable to locate the offending vehicles. Additionally, there have been recent complaints about garbage and debris issues in January 2025, which have been resolved, and two open service requests from December 2024 regarding a garbage can repair and a transportation engineering matter. The building's inspection history shows regular oversight by Housing Inspection Services, with all past violations being addressed and resolved, indicating compliance with safety and maintenance requirements.

Risk rating

How 907-909 Clayton 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
86th percentile

Out of 526 buildings in this neighborhood, 74 are predicted to be safer.
