Initial analysis

The 6-story, 39-unit apartment building at 1900 Gough Street in Pacific Heights, built in 1937 and currently owned by Switzer Investment LLC, has undergone significant modernization work over the past several years. Between 2022 and 2024, numerous units (105, 106, 201, 304, 305, 306, 501, 502, and 504) received substantial renovations including kitchen conversions, bathroom rehabilitations, and the installation of in-unit washer/dryer facilities, with associated plumbing and electrical upgrades. Most notably, in 2023-2024, there have been recurring issues with sleeping area requirements, as evidenced by two open violations from 10/24/2023 and 11/30/2023, though other fire safety concerns such as alarm systems and sprinklers were addressed or corrected between 2022-2023. The building has a history of fire safety inspections and violations, with multiple instances requiring attention to sprinklers, exit maintenance, and combustible materials between 2017-2023. While there have been several fire-related incidents recorded (mostly system malfunctions and smoke scares with no civilian injuries), the property has not experienced any major fire events. The building underwent a significant renovation period from 2012-2024, including a service upgrade in 2013, various unit improvements, and most recently, the installation of new appliances and electrical systems in Units 105 and 106 in 2024. Recent 311 calls from January 2025 indicate recurring issues with garbage and debris outside the building, with multiple reports of overflowing city garbage cans.

Risk rating

How 1900 Gough 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 963 buildings in this neighborhood, 838 are predicted to be safer.
