Initial analysis

The property at 1801 22nd Avenue in San Francisco's Central Sunset neighborhood is a two-story, five-unit multi-family residential building with ground-floor retail space, constructed in 1953 and currently owned by the Tong/Quan Family Trust. The building has undergone several significant modifications over its lifetime, with the most recent major work occurring in 2022 involving plumbing repairs, including work on a wall heater. Notable concerns emerged in mid-2022 regarding heating systems, with tenants reporting inadequate heat distribution and thermostat control issues, though these were addressed by August 2022. The building has a history of accessibility improvements, including significant modifications in 2012 to meet requirements for toilets and cashier facilities, along with the addition of sinks in a ground-floor restaurant space. The property experienced multiple violations in 2022 related to carbon monoxide/smoke alarm compliance and plumbing permits, all of which were abated by August 2022.

The building's maintenance and compliance history shows several permits for various improvements and repairs, including rear stairway repairs in 2015 and earlier renovation work during the 2000s. There were some concerning issues in 2022 regarding unauthorized work and heating system problems, with multiple violations cited during that period. Historical records indicate previous compliance issues from 2002 concerning unauthorized bathroom installation in Unit #1, which was eventually addressed. The property has maintained an active record of addressing both routine maintenance and required upgrades, though historical patterns suggest periodic challenges with permit compliance and system maintenance. A cooking-related fire incident was recorded in the past, though it was contained with no civilian injuries reported. The most recent activity surrounding the property has been primarily regarding street-level maintenance issues, as documented in multiple 311 calls throughout 2024, primarily related to garbage and debris concerns on the surrounding property.

Risk rating

How 1801 22Nd 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.
