Initial analysis

The three-unit multi-family residential building at 442-444 31st Avenue in San Francisco's Central Richmond neighborhood is a 2-story flats and duplex structure dating back to 1912, currently held in the Carolan Family Trust-bypass. The building's maintenance history reveals several significant structural and plumbing issues over the past decades. Most notably, in 2001, there was a serious plumbing problem when sewage backed into an apartment during clogs or heavy rainfall, attributed to drainage issues with the building's sewer pipe. The rear deck has been a recurring maintenance concern, with documented dry rot repairs needed in both 1993 and 1996, and an active housing complaint in 1996 regarding a deteriorated porch presenting possible collapse risks. Earlier improvements included interior renovations in 1991, with removal of lath plaster, insulation installation, and sheetrock work, along with window replacements in the front of the building.

The most recent building-related activity includes a completed gas piping repair in February 2014, suggesting ongoing attention to the property's infrastructure. The building has experienced various minor neighborhood issues as recorded in 311 calls, including recent noise complaints and street cleaning matters, none of which appear directly related to the building's structural or systems integrity. While many of the historical complaints have been resolved or closed, it is worth noting that the active housing complaint from 1996 regarding the rotten porch remains of concern, though this may be due to the age of the records rather than indicating ongoing issues. The property's permit history shows regular maintenance work being performed, though the pattern of repeated repairs to the rear deck suggests this has been a persistent maintenance challenge.

Risk rating

How 442-444 31St Ave'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 2250 buildings in this neighborhood, 1755 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

DBI complaint rate, owner's portfolio

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

Building age

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

12-Month severity forecast
No violation 52.7%
Moderate concern 38.0%
Severe concern 9.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
