Initial analysis

The two-unit residential property at 674-676 11th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex building constructed in 1923, currently owned by the Lai Ronald & Carolyn Trust. The building's maintenance history reveals some significant events, particularly a serious plumbing issue in December 2005 when overflowing sewage was reported as an ongoing problem over three months, which was formally addressed and abated within a week of filing. More recently, in 2017, the property underwent mechanical system improvements involving the installation of in-floor tubing, flues, thermostats, and boilers, though the associated plumbing permit expired in September 2017.

The building's recent history (2019-2024) shows minimal internal issues, with most incidents related to external factors. In 2019, a street space permit was issued for the property. The most notable pattern observed involves multiple 311 calls regarding abandoned vehicles and driveway blocking incidents in the vicinity, particularly between 2020-2024, with several resulting in citations. There was one environmental health request for service in November 2020 that was transferred to the DPH Environmental Health Healthy Housing & Vector Control Program, though the specific nature of this request is not detailed in the records. No recent fire incidents or civilian injuries have been reported at the property. While there have been multiple reports of parking issues near the property, these are external matters rather than building-related concerns.

Risk rating

How 674-676 11Th 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
72th percentile

Out of 1723 buildings in this neighborhood, 482 are predicted to be safer.

Model explanation

What's driving this score

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Estimated permit spend (past 7 years)

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

Building age

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

Moderate concern 14.5%
Severe concern 5.0%
