AI summary

The property at 775 40th Avenue in the Outer Richmond is a three-story, two-unit multi-family residential building constructed in 1924, currently owned by Steve M & Eva C Jeong Revoc. The building has undergone several significant modifications throughout its history, with the most recent major work being a reroofing project completed in 2020 at a cost of $16,500. In 2003, the building experienced an unauthorized construction incident involving the enclosure of an exterior deck at the top level, which resulted in a violation and required removal of the illegal construction, completed in May 2003. Earlier improvements during the 1980s and 1990s included the installation of a private residential elevator, addition of fire sprinkler systems, and conversion to a two-family use structure, along with various related modifications.

The property has experienced some maintenance issues recently, most notably a sewage backup incident in November 2023 that required attention from PUC Sewer Operations. There have been multiple parking-related incidents in the vicinity over the past year, including several instances of vehicles blocking driveways and reports of abandoned vehicles, all of which were addressed by parking enforcement. While the building's major structural and safety improvements appear to have been properly addressed through permits and inspections, the recent sewage issue suggests there may be some ongoing maintenance concerns worth noting. The property has a history of unauthorized construction that required remediation, though there have been no similar violations recorded in recent years.

Risk rating

How 775 40Th 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
81th percentile

Out of 1040 buildings in this neighborhood, 198 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 permits, owner's portfolio

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

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 80.1%
Moderate concern 14.2%
Severe concern 5.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
