Initial analysis

The two-unit residential building at 139 7th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1908 and currently owned by Hb Lau's Trust-2018. The building's documented history shows minimal significant events, with just one building complaint from June 2008 regarding unauthorized construction work involving tar that affected neighbors' units, though this issue was abated within two days.

More recently, the property has experienced recurring issues with driveway blocking, with six documented incidents between 2019 and 2024, all of which were resolved though officers were often unable to locate the offending vehicles. There have also been two tree maintenance requests due to overgrown trees in 2021 and 2023, both of which were resolved. The building had one false fire alarm incident recorded, with no civilian injuries reported. While the frequency of parking-related issues around the property is notable, there are no other significant safety or maintenance concerns on record.

Risk rating

How 139 7Th 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

Out of 660 buildings in this neighborhood, 185 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 85.0%
Moderate concern 11.0%
Severe concern 4.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
