Initial analysis

The property at 4451 24th Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1962, currently owned by Daniel Forkin and Susan Yamag. The building is undergoing an active permit process to legalize an additional dwelling unit on the first floor under the state ADU program, which will include the installation of NFPA 13 sprinklers. Historically, the building received a reroofing project completion in 2006.

The property has experienced several maintenance and safety issues in recent months, with the most significant recent events including a sewer odor incident from a catch basin in November 2024, and the legalization of an ADU that requires attention to fire safety modifications. Between January 2024 and November 2024, there were multiple service requests including streetlight issues, public health concerns, and various garbage-related complaints. Three fire complaints were recorded in October 2022 regarding weeds/grass and exit maintenance, which resulted in violation notices that were subsequently abated. The building has also encountered recurring challenges with illegal parking and driveway blocking, with enforcement officers often unable to locate the offending vehicles. While these incidents indicate some maintenance and public safety concerns in the surrounding area, the ongoing ADU legalization process demonstrates the owners' commitment to improving the property's compliance with current housing regulations.

Risk rating

How 4451 24Th 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

Out of 1879 buildings in this neighborhood, 413 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 77.0%
Moderate concern 13.4%
Severe concern 9.6%
