AI summary

The property at 821-823 Capp Street is a four-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by the Patricia Lopez Trust and constructed in 1916. The building's maintenance history reveals several significant events, most notably a series of housing code violations recorded in January 2004 that raised safety concerns, including issues with self-closing doors, combustible storage, fire safety equipment, and plumbing systems - all of which were successfully abated by March 2004. Three housing inspections were conducted between 2004 and 2010, with all cases being marked as not active.

The building has undergone various streetspace and sidewalk-related permits, including two issued in 2009 and one in 2007, though these do not represent internal building modifications. In recent years, from 2022 through 2024, there have been multiple 311 calls related to street and sidewalk conditions, with several reports of loose garbage requiring cleanup and some concerning issues like a collapsed sidewalk (noted as an unrestored PGE gas valve) and hazardous materials. The most recent concerns were recorded in 2023, including a noise complaint. A single welfare check incident related to fire safety was noted, with no civilian injuries reported. While the building's historical violations were promptly addressed, the recent pattern of 311 calls suggests ongoing concerns with external property maintenance and street conditions around the building.

Risk rating

How 821-823 Capp 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
45th percentile

Out of 2380 buildings in this neighborhood, 1309 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.

Neighborhood location

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

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 46.4%
Moderate concern 24.9%
Severe concern 28.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
