Initial analysis

The property at 2800-2802 21st Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, built in 1900 and currently owned by Stts Apartments LLC. The building has undergone several significant renovations over the past two decades, with the most recent major work occurring in 2018, including a substantial $40,000 remodeling project that updated three bathrooms and a kitchen with new tiles, fixtures, and cabinets, along with the installation of a 70-amp sub-panel and associated electrical work. Earlier maintenance included multiple repairs addressing dry rot issues at the front of the building in 2006, which involved replacing approximately 800 square feet of plywood and siding.

The building's history includes several code compliance issues that have since been resolved, particularly in the plumbing and gas systems. There were violations in 2007 related to unpermitted plumbing work and improper sewer connections that were abated by August 2007, and additional gas piping concerns in 2010 that were resolved in 2012. A building complaint from late 2006 regarding unauthorized construction work and debris was promptly addressed. More recently, the property has experienced some recurring issues with street cleaning and parking violations, as evidenced by multiple 311 calls in 2024 related to garbage and illegal parking. However, none of these recent incidents appear to directly impact building safety or habitability. The most recent fire-related incident was a false alarm in 2012 with no injuries reported, and there have been no tenant buyouts recorded at this address.

Risk rating

How 2800-2802 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

Out of 2380 buildings in this neighborhood, 857 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.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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 67.1%
Moderate concern 22.6%
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.
