Initial analysis

The two-unit residential building at 115-117 9th Avenue in Lake Presidio, owned by Tanaka Setsuko J & Isao, has undergone several significant maintenance and improvement projects since its construction in 1916. Most recently, in 2019, approximately $9,000 was invested in repairing rotted rear stairs, which was completed successfully. Earlier maintenance included a complete reroofing in 2015 at a cost of $9,500, following previous roofing work documented in 2000 and 1988. The property has also seen substantial safety improvements, such as the installation of a dedicated receptacle for a stair lift in 2008. Other historical improvements include a bathroom remodel and concrete slab repair completed in 1990, and the application of aluminum siding in 1986, though the related permits from that period have since expired.

The building's recent history has been relatively quiet in terms of major issues, with only routine maintenance and infrastructure updates being recorded. There have been several 311 calls related to the immediate vicinity of the property, including a parking violation in September 2024 and a flickering streetlight issue in 2019, both of which were resolved through normal city processes. Notably, there were multiple reports of abandoned scooter/motorcycle vehicles in the immediate vicinity between 2016-2017, though these were external to the property and were consistently resolved when city authorities responded to the reports. The building appears to be well-maintained, with regular updates to critical elements like roofing and safety features, as evidenced by the active permit history spanning several decades.

Risk rating

How 115-117 9Th 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, 99 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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.

12-Month severity forecast
No violation 82.8%
Moderate concern 13.8%
Severe concern 3.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
