Initial analysis

The two-story, 10-unit multi-family residential building at 335 2nd Avenue in the Inner Richmond neighborhood, owned by Denise Yvonne Lee, has undergone several significant safety and maintenance upgrades since its construction in 1963. Most notably, the building completed a mandatory soft-story seismic retrofit in 2016 (as a Tier 3 property), demonstrating compliance with San Francisco's seismic safety requirements. The building's fire safety systems have received substantial attention, with a comprehensive fire alarm system upgrade implemented between 2020-2021 at a total cost of $23,000, including the installation of radio monitoring and low-frequency sounders in sleeping rooms. The building has experienced persistent sewer issues, with multiple documented sewage backup incidents between 2018-2023, including the most recent occurrence in October 2023. Housing inspection records from 2015 revealed several fire safety violations related to fire escape maintenance, carbon monoxide alarms, and ceiling repairs in the garage area, though these were subsequently abated. The building has maintained regular upkeep, with significant work including a reroofing project in 2010 ($18,000), window replacements (1991), and a sewer/housetrap replacement completed in 2018. Recent fire safety inspections have identified issues with fire extinguishers (most recently in 2023) and alarm systems, though these violations have generally been promptly corrected or resolved. The property's maintenance history suggests active management, though the recurring sewer issues and occasional fire safety violations warrant attention.

Risk rating

How 335 2Nd 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
8th percentile

Out of 1723 buildings in this neighborhood, 1585 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.

Number of units

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

Building size

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

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 59.1%
Moderate concern 27.8%
Severe concern 13.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
