Initial analysis

The two-unit residential building at 1283 42nd Avenue in the Outer Sunset, owned by George A Poon and Mariasinag, has a storied history dating back to its 1912 construction. Most notably, the property experienced significant permit compliance issues in 2016, when multiple violations were documented regarding unpermitted plumbing, electrical work, and construction of a rear extension, which were ultimately addressed through permits to remove the unauthorized modifications. This period of non-compliance also prompted a director hearing in May 2016 and required the removal of unpermitted plumbing and electrical work in October 2016, with all violations being abated by November 2016. The building's maintenance history shows regular attention to roofing needs, with reroofing projects completed in 1999 and 2011, and a notable enforcement action in 1988 when an illegal third unit was removed from the second floor. More recently, there was an active complaint in October 2018 regarding apparent unauthorized construction work involving cement pouring in the backyard, suggesting potential ongoing issues with compliance and construction oversight.

The property has experienced recurring parking-related issues, particularly in 2024, with multiple complaints about vehicles blocking driveways and parking on sidewalks, resulting in several citations and one vehicle tow. A fire complaint regarding unlicensed auto repair was filed in June 2016 and resolved by July 2016. The building's documented history includes one incident from 1996 involving exposed electrical wiring that was promptly addressed. While the major compliance issues from 2016 were resolved, the 2018 complaint and recent parking challenges suggest ongoing concerns about both property maintenance and neighborhood interactions.

Risk rating

How 1283 42Nd 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
63th percentile

Out of 632 buildings in this neighborhood, 234 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 70.5%
Moderate concern 24.0%
Severe concern 5.5%
