Initial analysis

The 6-unit, 3-story apartment building at 3518 16th Street, owned by the Chen Family Revocable Trust, has undergone several significant improvements over recent years, with the most recent being a complete re-roofing project in July 2024 costing $15,000. In 2023, the building received a comprehensive fire safety upgrade including a new fire alarm system with multiple components to meet current safety codes. The property has a documented history of maintenance and compliance actions, including previous re-roofing work in 2005, deck and stair replacements in 2001, and vinyl siding application in 2002.

The building experienced a series of fire safety and lead-related violations in 2002, all of which were resolved by August 2002, and there were additional maintenance issues noted in 2005 and 2015 regarding weatherproofing and paint conditions. A notable concern emerged in 2017 with a complaint about mold throughout one unit. More recent history shows multiple 311 calls from January 2025 regarding waste and debris issues near the property, though these are external to the building itself. The only recorded fire incident was classified as a "400 Hazardous condition, other" with no civilian injuries noted. The building has undergone regular inspections by Housing Inspection Services, with the most recent routine inspection in 2015 showing no violations found.

Risk rating

How 3518 16Th St'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
29th percentile

Out of 1278 buildings in this neighborhood, 907 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.

Estimated permit spend (past 7 years)

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

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 48.0%
Moderate concern 26.7%
Severe concern 25.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
