Initial analysis

The property at 631 3rd Avenue in the Inner Richmond is a 2-unit, 2-story multi-family residential building constructed in 1904, currently owned by the Lee Survivors Trust. The building experienced significant maintenance issues in 2003, when multiple building violations were documented on September 24th, including problems with wood stairs and decks, roof weatherproofing, emergency exits, smoke detectors, kitchen floor coverings, and window repairs. Of particular concern were violations related to a "safety hazard" with rear stairs, which were subsequently addressed through a repair permit completed in November 2003. A reroofing project was also undertaken in 2005 costing $5,900, though this permit is now listed as expired. More recently, in October 2010, there was a complaint about unauthorized construction of a garbage bin enclosure and additional garage space, though this complaint is now listed as not active.

The building has had several maintenance-related incidents recorded through 311 calls, including three instances of garbage cans being left out continuously between 2010-2012, and a water leak issue reported in October 2010 involving root intrusion in the sewer system. The property has experienced recurring issues with abandoned vehicles in front of the building, with four such reports filed between 2016-2021, though these were not directly related to the building's condition or maintenance. While the building had notable safety and maintenance concerns in the early 2000s, the records show that many of these issues were addressed, though some permits are now listed as expired. The most recent documented issues have been primarily related to waste management and street use rather than building safety or maintenance concerns.

Risk rating

How 631 3Rd 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
77th percentile

Out of 1723 buildings in this neighborhood, 396 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 82.1%
Moderate concern 12.7%
Severe concern 5.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
