Initial analysis

The property at 3214-3216 18th Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood, owned by Judy Xihua Cheung. Built in 1900, this flats/duplex-style building has experienced several significant issues and repairs over its history. Most notably, in 2012-2013, the property underwent a series of repairs following multiple housing violations issued in June 2012, including problems with smoke detectors, plumbing fixtures, lighting, interior surfaces (including mold and mildew), stairs, heating systems, and security requirements. During this period, the building also received new gas wall heaters for both units and bathroom repairs, though some earlier permits for window replacements from 2003 (for two front windows, one kitchen window, and one bedroom window) had expired.

More recent concerns include a 2014 complaint about unsafe floors presenting a trip hazard, and ongoing maintenance issues as evidenced by numerous 311 calls in 2024. These 311 calls have documented various problems such as graffiti, sewer discharge issues, garbage and debris accumulation, and street cleaning needs. A significant historical incident occurred in 2008 when the building, previously a restaurant and flat, was reported as burned and condemned, suffering from blight, with noted concerns about rotting and structural decay. The most recent fire-related record is from March 2020, indicating multiple fire code violations with respect to sprinkler service. While many of the earlier housing violations from 2012-2013 were eventually abated, the building's maintenance history demonstrates recurring challenges with both interior living conditions and exterior upkeep.

Risk rating

How 3214-3216 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 2380 buildings in this neighborhood, 333 are predicted to be safer.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Moderate concern 12.3%
Severe concern 6.6%
