Initial analysis

The two-unit residential building at 246-248 18th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1915, currently owned by Huang Cong-ying. The property has undergone several significant improvements and faced some regulatory challenges over its history. Most recently, in June 2023, the building received a substantial re-roofing project valued at over $20,000, which is a positive maintenance update. The building's history shows attention to structural integrity, with completed repairs in 1991 addressing stucco, dry rot, and the installation of anchor bolts. Notably, there was a significant regulatory intervention in the late 1990s when an illegal basement unit was reported in January 1997, leading to removal of an unauthorized kitchen and bathroom in March 1997, with the matter officially abated by August 1997. The building underwent various legitimate improvements in the 1990s, including kitchen remodeling in the upper unit (1995), roofing work (1995), and garage concrete slab replacement (1992).

The property has experienced recurring issues with sidewalk parking violations in recent years, particularly between 2019 and 2024, though these external matters do not directly impact building safety or resident conditions. Four sidewalk parking incidents were reported through 311 calls between 2019 and 2024, with one resulting in a citation (March 2023) and others resulting in officer response but unable to locate the offending vehicle. A customer callback regarding color curb services was recorded in March 2012, though this has no direct relevance to the building's residential status. The building's permit history, primarily through the 1990s and 2000s, suggests regular maintenance and occasional violations, though no recent permits indicate significant structural changes or concerns since the 2023 re-roofing project.

Risk rating

How 246-248 18Th 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.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 518 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 81.8%
Moderate concern 15.3%
Severe concern 2.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
