Initial analysis

The property at 3855 21st St is a three-unit, two-story multi-family residential building constructed in 1900, currently owned by the John & Karen Delara Family Trust. The building has undergone several significant improvements over the past two decades, with particular attention to safety systems. In 2012, the installation of a comprehensive fire alarm system was completed, including multiple pull boxes, detectors, and horns/strobes, following a violation notice that was abated in August 2012. The building also underwent various staircase safety improvements in 2012, including handrail installations and repairs, with work continuing through 2012 to address several completed and final inspection requirements.

More recent improvements include the installation of two direct vent gas inserts in 2020. The building has been the subject of multiple routine housing inspections from 1996 through 2007, and a significant complaint was filed in May 2012 regarding several issues including possible unauthorized units, window problems, lack of smoke detectors, water pressure concerns, and an unsafe deck, though these issues were marked as not active by August 2012. While the building has had numerous parking-related incidents recorded through 311 calls in the past year, including multiple instances of driveway blocking and abandoned vehicles, these are street-related issues and not indicative of building conditions. A single cooking-related fire incident was recorded, but it was contained with no civilian injuries reported. The building's permit history shows regular maintenance and safety upgrades, with particular attention to preserving its original Victorian style during façade work proposed in 2009, though some permits from that time expired.

Risk rating

How 3855 21St 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
39th percentile

Out of 1278 buildings in this neighborhood, 780 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.

Neighborhood location

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

Neighborhood (ZIP code)

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

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 47.6%
Moderate concern 22.6%
Severe concern 29.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
