Initial analysis

The property at 1600-1602 21st Avenue is a one-story, multi-family residential building located in San Francisco's Central Sunset neighborhood. Built in 1941 and containing two units, the building has undergone several significant improvements over the past two decades. Most recently, in late 2020, the kitchen and bathroom received a $30,000 remodel, including new cabinets, counters, and fixtures, with associated plumbing and electrical work completed between December 2020 and January 2021. In 2021, substantial upgrades were made to the building's systems, including the installation of a new 200-amp electrical service panel and the replacement of two furnaces in the garage. The building previously underwent window upgrades in 2004, when eight vinyl windows were installed without changing their size or location.

Of particular note is an active building complaint filed in April 2002 regarding unauthorized construction of a second-floor section in the former garage space, which remains unresolved as of the most recent records. More recently, in December 2024, there was a sewage backup incident involving a side sewer vent, though this was promptly investigated and resolved with no significant issues observed. The property has experienced recurring issues with illegal parking and abandoned vehicles in the vicinity between 2022 and 2024, with multiple citations issued and vehicles towed, though these are not directly related to the building's condition or management. Regular street cleaning and sanitation issues have been documented through 311 calls, primarily concerning loose garbage on the street, with the most recent incident occurring in May 2024.

Risk rating

How 1600-1602 21St Ave'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
94th percentile

Out of 814 buildings in this neighborhood, 49 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.

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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 82.1%
Moderate concern 13.8%
Severe concern 4.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
