Initial analysis

The 9-unit, 3-story apartment building at 1901-1911 Webster Street in Lower Pacific Heights, built in 1910 and currently owned by Chouaki Maissa, has undergone several significant safety upgrades in recent years. Most notably, the building completed a mandatory soft-story retrofit in 2015 (with a cost of $60,000) to improve seismic safety, followed by comprehensive fire alarm system upgrades in 2021-2024 to install low-frequency sounders and replace the fire alarm control panel, ensuring compliance with current fire safety codes. The building has experienced recurring fire safety issues, with multiple violations and complaints about alarm systems and fire extinguishers between 2016 and 2023, though all have been marked as corrected or abated.

The property has had several maintenance and safety concerns over its history, including a 2019 complaint about mold and water damage in bathrooms, unsafe basement stairs, and exposed wiring, as well as plumbing issues in 2006 involving low water pressure and possible leaks. Historical violations from 2000-2011 included problems with smoke detectors, security features, and fire extinguisher maintenance, all of which were subsequently resolved. Recent activity includes multiple 311 calls in 2024 regarding sidewalk defects and street cleaning issues, with the most recent being a sidewalk defect issue reported in January 2025. The building's plumbing infrastructure has seen several updates, including a partial hot and cold water re-pipe in 2022 and various bathroom and kitchen renovations. While the building has had its share of maintenance challenges, recent years have shown consistent attention to fire safety improvements and structural compliance requirements.

Risk rating

How 1901-1911 Webster 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.
