Initial analysis

The 12-unit apartment building at 2211 18th Street in Potrero Hill, owned by Rkr Investments, is a three-story structure built in 1917 that has undergone significant safety improvements in recent years. Most notably, the building has completed mandatory seismic strengthening to comply with San Francisco's Soft Story Program, with work including the installation of 35 fire sprinkler heads throughout ground-floor units, seismic reinforcement, and fire alarm system upgrades. The building has also seen recent improvements to accessibility, with ADA bathroom modifications completed in 2023. In 2024, work continued with the legalization of gas fireplaces and furnace installations in units 12, 13, and 14.

The property has experienced some regulatory challenges, with multiple building violations and complaints filed in 2022 regarding various safety issues, including fire escape maintenance, fire proofing, light and ventilation, and structural maintenance. These violations were notably addressed through completed work and inspections, with recent fire violation correction occurring in May 2024. The building's fire safety systems have required ongoing attention, with multiple historical fire complaints related to alarm systems and extinguishers between 2005 and 2024. While most recent permits and inspections have been completed successfully, including the installation of new fire safety equipment and system upgrades, there are still some open 311 calls from 2024 concerning curb defects and garbage can repair. The building's history also shows various routine inspections and minor maintenance issues, such as hot water problems in 2006 and exterior cleaning concerns documented through 311 calls.

Risk rating

How 2211 18Th 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 726 buildings in this neighborhood, 711 are predicted to be safer.
