Initial analysis

Located in San Francisco's Central Richmond neighborhood, 266 21st Avenue is a 3-story, 15-unit multi-family residential building constructed in 1963 and currently owned by Kukman23 LLC. The property has undergone significant recent improvements, including the installation of five new ADUs in 2021 (valued at $385,000) and a completed soft-story retrofit in 2017 (costing $122,000) to comply with seismic safety requirements. The building has experienced recurring elevator issues, particularly notable in 2008 when complaints highlighted concerns about accessibility for elderly and disabled residents, though there have been no such complaints in recent years. Recent fire safety compliance has been maintained, with the most recent fire safety inspections in September 2023 showing corrected conditions for alarm systems and extinguishers. The building has a history of various unit upgrades and maintenance work, including a 2019 structural revision and multiple cosmetic improvements to individual units between 2005-2010.

The property has faced several challenges over the years, including multiple building complaints, some related to unauthorized unit conversions and common area modifications. Notable historical violations from 2002 included issues with fire safety systems and plumbing/electrical concerns, though these were abated by May 2002. The building's management has addressed various maintenance issues, including a notable water outage in 2007 and multiple reports of garbage and debris outside the building in 2024. Recent planning and permit activity includes ongoing work as of October 2024 to revise the layout of studios #4 and #5 and modify a proposed lightwell. The building's fire alarm system has required periodic attention, with violations recorded in 2020 and 2021, though these were subsequently corrected. The property has maintained active compliance with San Francisco's soft-story retrofit program, achieving full completion and CFC issuance.

Risk rating

How 266 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

Out of 2250 buildings in this neighborhood, 2115 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Property class (A15)

The assessor's property-class code, which correlates with building type and the violation rates the model expects.

12-Month severity forecast
No violation 36.3%
Moderate concern 52.4%
Severe concern 11.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
