Initial analysis

The two-story, 6-unit multi-family residential building at 1644-1652 Irving Street in San Francisco's Inner Sunset neighborhood, built in 1923, has experienced several significant maintenance and safety issues over the past decades. Most notably, in 2023, multiple violations were documented regarding building safety and maintenance, including problems with lead paint, a non-functional garbage chute, issues with fire safety systems, and concerns about carbon monoxide and smoke alarms. These violations, though marked as not active with some addressed by May 2023, indicate a pattern of deferred maintenance. The building underwent extensive repairs in 2011-2012, addressing multiple instances of dry rot in various locations, including the west side, front wall, and above the optometry store. Window and door replacements were completed during this period, with five aluminum windows and two doors installed at a cost of $8,000.

The property has a documented history of various maintenance issues, including plumbing concerns with exposed wiring (2022), water drainage problems (2022), and the need for building system repairs. In March 2023, a complaint was filed regarding the lack of an intercom or communication system for the multi-story building, which could pose safety concerns. A routine inspection in 2001 revealed multiple safety concerns that were subsequently addressed, but the building's age and maintenance history suggest ongoing upkeep will likely be necessary. Recent 311 calls from 2024 show numerous reports of street cleaning issues and environmental hazards in the vicinity, though these appear to be external to the building itself.

Risk rating

How 1644-1652 Irving 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.
