Initial analysis

The two-unit residential building at 2832 21st Street in San Francisco's Inner Mission district is a two-story flats and duplex structure built in 1907, currently owned by Ana G Pineda. The most recent significant structural improvement was completed in February 2024, when a $16,500 re-roofing project was finished. The building's maintenance record shows relatively minimal major work, with only one other documented permit from 2007 for sidewalk work.

The property has experienced several recurring issues with parking violations between 2023 and 2024, with seven documented cases of driveway blocking, primarily involving Sprinter vans or commercial vehicles. While these cases were officially reported and resolved, enforcement officers were generally unable to locate the offending vehicles. There have also been two instances of garbage and debris issues reported in mid-2024, both involving abandoned furniture and other waste, though these cases were ultimately resolved. A noteworthy public safety incident occurred in 2024 when a natural gas leak was reported, though fortunately resulted in no civilian injuries. While the building's documentation shows some neighborhood maintenance issues, particularly related to parking violations, the recent completion of the roofing project suggests ongoing property maintenance is being attended to.

Risk rating

How 2832 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.
