Initial analysis

The two-unit multi-family residential building at 1246-1248 46th Avenue in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1908, currently owned by the Anthony K Tam Trust. The building has undergone several significant renovations and repairs over its history, including a substantial 3-story horizontal rear extension completed in 1998 at a cost of $130,000, and various repairs in response to damage incidents such as a garage fire in 1999, front stairway stucco removal in 1998, and damage to the rear wall and porch in 1989. Historical records show some structural concerns in the early 1980s with a violation report, and complaints regarding unauthorized facade changes and construction activities in 2000. More recent building maintenance includes a street space permit issued in 2020, though there has been a notable pavement defect issue in late 2024 involving a trench in front of the building.

The property has experienced recurring issues with sewer systems, with documented backups in both 2011 and 2018, and multiple instances of abandoned garbage requiring city cleanup in 2014. While there have been several parking-related incidents in the vicinity, including multiple citations for sidewalk parking between 2018-2024, these primarily affected public spaces rather than the property itself. The building's maintenance history shows regular upkeep over the decades, with no documented safety incidents or code violations in recent years that would raise significant concerns about resident safety or building integrity. Recent service requests related to the property have mostly been for routine street maintenance and parking enforcement, suggesting stable building conditions in recent times despite the historical record of repairs and improvements.

Risk rating

How 1246-1248 46Th 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 632 buildings in this neighborhood, 145 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 size

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

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 49.2%
Moderate concern 23.5%
Severe concern 27.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
