Initial analysis

The property at 345-355 Presidio Ave is a two-story, six-unit multi-family residential building with commercial space, built in 1906 and currently owned by Ki Lau & Mabel Ng Revocable Living Trust. The building has undergone several significant accessibility improvements, most recently in September 2023 with two permits filed for ADA compliance work including the installation of power doors and hardware relocation, each with an estimated cost of $3,500. A notable accessibility project in 2010 was completed successfully, involving the installation of a commercial vertical platform lifter and restroom upgrades. The building has a documented history of plumbing issues, particularly in 2015 when multiple sewer problems were reported, including leaks and breaks in the building's drainage system, though these were resolved within months. Other maintenance work includes a $29,500 reroofing project conducted in 2017 and various plumbing system upgrades between 2010-2015.

The building has faced multiple regulatory inspections and complaints over its history, including a 2008 routine apartment house inspection that uncovered several safety concerns that were subsequently addressed by November 2015. These concerns included the need for security improvements, fire extinguisher maintenance, and accessibility features. More recent activity includes several 311 calls in 2024 regarding sidewalk accessibility and parking issues, though these are primarily related to public space rather than building conditions. The property has maintained active compliance with fire safety regulations, though it experienced an overcrowding issue in 2012 that was promptly corrected. The current owners have regularly addressed building code requirements, as evidenced by multiple completed and ongoing accessibility improvements, suggesting active management of the property's maintenance and compliance needs.

Risk rating

How 345-355 Presidio 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
37th percentile

Out of 181 buildings in this neighborhood, 114 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 size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 61.6%
Moderate concern 25.8%
Severe concern 12.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
