Initial analysis

The property at 647 35th Avenue in San Francisco's Outer Richmond neighborhood is a one-story duplex/multi-family residential building constructed in 1987, currently under the ownership of Richard H & Janet K Kung Trust. The building has undergone significant modifications and improvements over the years, with the most substantial recent transformation occurring between 2019-2020 when an additional unit (Unit #3) was legalized on the first floor, requiring comprehensive work including the installation of a kitchen, living space, bathroom, and two bedrooms, along with new utilities (water heater, furnace, washer/dryer). This upgrade was followed by the installation of a new fire sprinkler system for ground floor ADU units in 2020, including a comprehensive fire safety upgrade completed in 2021 with the installation of a new fire alarm monitoring system.

The building has seen regular maintenance and improvements over the years, including window replacements (12 front-facade windows in 2015), re-roofing (2015), and earlier exterior improvements such as vinyl siding installation in 1994. However, there have been recurring sewer-related issues, with multiple incidents of sewage back-ups reported between 2020 and 2024, most recently in October 2024, indicating an ongoing infrastructure challenge. The building's parking situation has experienced several enforcement actions, with multiple reports of driveway blocking between 2020-2022, though these are external to the building's condition. A single fire alarm activation was recorded with no fire or injuries involved. The property appears to be managed with regular updates to safety systems, though the recurring sewer issues may impact resident experience.

Risk rating

How 647 35Th 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.

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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 84.9%
Moderate concern 9.1%
Severe concern 6.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
