Initial analysis

The two-story, six-unit multi-family residential building at 305 10th Avenue in the Inner Richmond, owned by Ken Ho Development LLC, has undergone several significant improvements since its construction in 1963. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $72,000, achieving Tier 3 status with the Certificate of Final Completion (CFC) issued by the San Francisco Department of Building Inspection. Other permitted improvements include street space modifications in 2018 and the installation of vinyl siding to wood areas of the building in 2000. The building has experienced some concerning maintenance and safety issues over the years, including a notable incident in January 2017 involving rodent complaints linked to an unkempt garage space containing abandoned items and food. Previous complaints in 1994 documented heating system failures, and a 2016 fire safety complaint reported no access to the building for inspection. Recent infrastructure maintenance issues have been documented through various 311 calls between 2023-2025, including a sewage backup discharge from the side sewer vent in October 2024 and multiple reports of hazardous materials (glass) on the sidewalk in October 2023. The building's recent permit history shows some minor street space modifications and previously completed improvements have generally been properly documented and completed, though several historical housing inspection cases from the 1990s and 2000s indicate past routine maintenance and safety concerns that appear to have been resolved.

Risk rating

How 305 10Th 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
26th percentile

Out of 1723 buildings in this neighborhood, 1275 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 69.5%
Moderate concern 18.7%
Severe concern 11.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
