Initial analysis

The three-story multi-family residential building at 1486-1490 15th Street in the Inner Mission, owned by Kerwin C K Ng & Karen N Kay, has undergone significant maintenance and improvements since its construction in 1910. Most notably, the building completed a mandatory soft-story retrofit in 2020, demonstrating compliance with San Francisco's seismic safety requirements. In September 2021, the building experienced fire damage requiring repairs to exterior siding and window replacements in apartment #399, with work completed at a cost of $125,000. The property has also received recent maintenance attention, including a $24,000 reroofing project issued in April 2024.

The building's history includes several important renovations and upgrades, such as multiple apartment remodels in the early 2000s (including kitchen and bathroom updates in units 399 and 1486), and earlier attempts to address soft-story compliance in 2017. A cluster of health and safety violations was recorded in 2010, including requirements for self-closing doors, gas utility shutoff tools, fire extinguishers, and gas meter instructions; however, all these violations were abated by July 16, 2010. More recent concerns have primarily involved exterior maintenance, with multiple 311 calls regarding garbage and debris between November and December 2024, including reports of graffiti that required contractor intervention. The building has undergone regular safety inspections, with the most recent soft-story compliance verified as completed with a Certificate of Final Completion (CFC) issued.

Risk rating

How 1486-1490 15Th 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

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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Number of units

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

12-Month severity forecast
No violation 38.8%
Moderate concern 45.1%
Severe concern 16.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
