Initial analysis

The property at 3095 21st Street is a two-story, 5-unit multi-family residential building constructed in 1890, currently owned by Edwin Yuen and Kathryn K. Lee. The building has undergone several significant improvements and maintenance projects over the past two decades, most notably an ADA compliance upgrade to the unisex restroom completed in 2019, and recent filed permits in 2023 and 2025 for entrance modifications and ground-floor restaurant space renovation, including removal of interior finishes and exterior signage. The building has experienced some safety concerns, particularly a notable incident in May 2017 involving unauthorized roof access that raised safety concerns following a similar incident at a neighboring property. A fire complaint was filed in November 2020 regarding operation without a permit, though this was resolved by March 2023.

The building's maintenance history shows regular upkeep, including a reroofing project completed in 2000, multiple interior remodels in 2003-2004 (including Apartment 2), and various plumbing and electrical upgrades. While the building has experienced several fire alarm activations, these have generally been for non-emergency reasons such as system malfunctions or false alarms, with only one documented cooking-related incident that remained contained. Recent 311 calls from late 2024 have primarily concerned parking issues and illegal postings, though there are some open concerns regarding sewer odor and garbage management in the vicinity. The property has undergone routine housing inspections over the years, with most complaints being addressed and closed, though one notable 2002 complaint regarding illegal cooking and heavy foot traffic was filed.

Risk rating

How 3095 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
48th percentile

Out of 2380 buildings in this neighborhood, 1238 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.

Number of units

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

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 36.5%
Moderate concern 53.2%
Severe concern 10.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
