Initial analysis

The multi-family residential building at 642-652 Shrader Street, located in the Haight Ashbury neighborhood, is a 2-story, 6-unit structure built in 1900, currently owned by Jan Chernoff & Isabel Wade. The property has experienced multiple significant maintenance and compliance issues over the past several years, with the most concerning being an active violation (filed September 2011) regarding unauthorized interior gutting work and framing of walls at 642 Shrader Street without proper permits. This building has a documented history of structural and safety concerns, including issues with a shifted chimney stack in 2009, balcony repairs, and multiple instances of water damage and rodent infestations reported in 2011. Several permits were pulled between 2007 and 2013 for various repairs, including a sewer line repair in June 2013, which suggests ongoing maintenance challenges.

The building has faced various building code violations and safety concerns that required attention, including the need for handrails, self-closing doors, fire extinguishers, and rodent remediation - most of which were addressed under routine inspections in 2011. Three building complaints in 2010-2011 regarding possible illegal unit construction in the storefront area were investigated, though these complaints are now listed as not active. Recent history shows continuing maintenance and compliance issues, as evidenced by multiple 311 calls in late 2024 regarding parking violations, graffiti, and other neighborhood concerns around the property. While some work has been completed under various permits, several of these permits are now expired, and there are multiple "open" statuses on recent 311 calls relating to the property's immediate vicinity.

Risk rating

How 642-652 Shrader 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
65th percentile

Out of 581 buildings in this neighborhood, 203 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

12-Month severity forecast
No violation 66.1%
Moderate concern 15.4%
Severe concern 18.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
