Initial analysis

The property at 3348-3350 21st Street is a historic three-story multi-family residential building constructed in 1885, containing 4 units and currently owned by Laura Rogers. The building has undergone several significant improvements and maintenance projects over the past decade, including a comprehensive soft-story retrofit completed in 2016 (cost: $80,000) to enhance seismic safety, and recent sewer lateral replacements in July 2023. The property has seen consistent interior improvements, with multiple kitchen and bathroom remodels throughout the years, most recently in 2017 (cost: $30,000). Major system upgrades include electrical panel replacement and wiring improvements in 2009, and foundation repairs in 2013 (cost: $15,000).

The building's maintenance history shows attention to safety and compliance issues, with various routine inspections conducted by Housing Inspection Services. While there were multiple violations recorded in the 2000-2011 period related to fire safety, smoke detection, and lead paint concerns, all of these issues have been officially abated. The most recent open complaint from 2014 regarding a broken glass pane remains active. The property has also experienced regular street maintenance challenges as evidenced by multiple 311 calls between 2019-2023 regarding sidewalk cleaning and tree maintenance issues.

Risk rating

How 3348-3350 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
64th percentile

Out of 1278 buildings in this neighborhood, 460 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.

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 60.8%
Moderate concern 22.1%
Severe concern 17.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
