Initial analysis

The three-story multi-family residential building at 330 21st Avenue in the Central Richmond neighborhood, owned by Michael & Kyle Rabkin, was constructed in 1912 and contains two units on one parcel. The property has undergone significant improvements over the past decade, with major renovations completed in 2013-2014 including comprehensive remodeling of kitchens and bathrooms, addition of living spaces, and electrical system upgrades. These improvements featured the installation of new plumbing systems, including water heaters, furnaces, and bathroom facilities, as well as extensive electrical work with new lighting, appliances, and smoke detectors. The building's exterior has been maintained with siding replacement in 2015 and recent solar panel installation (October 2023) comprising an 18-module, 7.2 kW system.

The property has a history of addressing maintenance and safety concerns, including the replacement of a house trap (2015), reroofing (2006), and repair of front stairs due to dry rot (1994). Recent 311 calls from 2022-2025 primarily relate to parking issues in the vicinity of the property, including reports of abandoned vehicles and blocked driveways, though these external matters do not directly reflect on the building's condition or management. The building's comprehensive renovation history and recent solar upgrade suggest ongoing maintenance and improvement efforts by the current owners, with no documented safety violations or major maintenance issues in recent years.

Risk rating

How 330 21St 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
72th percentile

Out of 2250 buildings in this neighborhood, 630 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 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 77.1%
Moderate concern 15.7%
Severe concern 7.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
