Initial analysis

The Wong/Lam Family Trust owns this two-unit multi-family residential building located at 1442 11th Avenue in San Francisco's Inner Sunset neighborhood. Built in 1991, this two-story structure underwent several significant modifications during its construction phase, including both vertical and horizontal additions in 1990-1991. The building has received regular maintenance over the years, including a 2020 project that replaced 14 backyard windows and siding with Hardi-plank material, a 2008 reroofing project, and a 2010 spot plumbing repair. A notable maintenance issue arose in 2017 when a complaint was filed regarding a re-routed dryer vent that allegedly discharged into a neighboring building, though this complaint is currently listed as "Not Active."

The property has faced persistent parking-related challenges, particularly in 2023-2024, with multiple reports (at least eight documented cases) of driveway blocking and sidewalk parking violations. These parking issues have prompted various responses from parking enforcement, with most cases being addressed by officers, though some were labeled as "Unable to Locate" or "Could Not Be Validated." Additionally, there was a planning matter regarding a rear addition that was built 3.5 feet beyond the scope of the approved building permit application; this issue was ultimately resolved with an "Approved" status in planning records.

Risk rating

How 1442 11Th 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
76th percentile

Out of 1493 buildings in this neighborhood, 358 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 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 86.2%
Moderate concern 10.3%
Severe concern 3.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
