Initial analysis

The property at 1343-1345 8th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, three-unit multi-family residential building constructed in 1923, currently owned by the Woon Yee Yee Trust. The building has experienced recurring sewer line issues, with eight documented sewage backup incidents between 2016 and 2021, though one significant repair was completed in 2014 involving the replacement of a 20-foot sewer line and house trap. A major concern was identified in 2010 regarding an unauthorized basement unit that reportedly added illegal living space, kitchen, and bathroom facilities, along with several associated safety violations including questions about fire rating materials, smoke detectors, and proper light/ventilation requirements; these violations remain active as of the latest record. The building underwent a routine housing inspection in 2002 that revealed multiple safety concerns, including issues with the fire escape ladder, fire safety equipment, gas meter instructions, back stairs/decks, exit hallway obstructions, and more, all of which were apparently resolved by April 2002.

The property's maintenance history shows ongoing infrastructure challenges, particularly in the plumbing system, with multiple sewer-related service calls in 2016-2017 and the 2014 sewer line replacement work. While some historical violations have been addressed, the presence of active violations from 2010 related to the unauthorized basement unit and various safety features raises ongoing compliance concerns. The building's documented history includes one recent parking-related incident from 2021, though this is unrelated to building conditions or systems. The property management has apparently taken steps to address some historical violations, as evidenced by the 2014 plumbing repair and the resolution of many 2002 inspection issues, but the persistence of certain violations suggests some building code compliance challenges remain.

Risk rating

How 1343-1345 8Th 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 1493 buildings in this neighborhood, 851 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.

Construction spend, owner's portfolio

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

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 59.0%
Moderate concern 27.6%
Severe concern 13.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
