Initial analysis

The property at 131-135 Fair Oaks Street is a 2-story, 7-unit multi-family residential building located in San Francisco's Noe Valley neighborhood. Built in 1910, the building has undergone several significant improvements in recent years, with the most notable being a comprehensive fire alarm system upgrade completed in August 2023 to comply with San Francisco Fire Code requirements, including the installation of new sounders, smoke detectors, and monitoring equipment at a cost of $24,632. In 2018, the building underwent a seismic upgrade to comply with mandatory safety standards. A substantial renovation was completed in 2016 when the powder room in unit #131 was converted into a full bathroom, and in 2012, significant electrical infrastructure improvements were made including the installation of a 200-amp electrical service with eight meters.

The building's maintenance history shows attention to safety systems, though there were some concerning issues in the past. A cluster of fire safety violations was recorded in March 2011, including problems with fire extinguishers, the central alarm system, and smoking detection equipment, all of which were resolved by March 18, 2011. A significant complaint was filed in November 2005 detailing multiple issues including peeling paint, plumbing problems, and rodent infestation, which was addressed by June 2007. More recently, in 2012, there was a complaint regarding electric circuit breaker issues and inadequate heating, though this was also resolved. The property has maintained regular inspections and upgraded its systems to meet current codes, with no active violations or complaints on record as of now.

Risk rating

How 131-135 Fair Oaks 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.

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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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

12-Month severity forecast
No violation 62.8%
Moderate concern 29.6%
Severe concern 7.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
