Initial analysis

The property at 311-313 22nd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, constructed in 1912 and currently owned by Zhang Xiu Fang. The building's maintenance record shows several significant improvements over the years, including a complete reroofing project in 1991 and an electrical service upgrade in 2004 that introduced 200-amp service with three sub-panels. A noteworthy concern was raised in September 2014 when a complaint was filed regarding an illegal stairway in the backyard, though this complaint is currently listed as "Not Active" with Housing Inspection Services.

The property has experienced various external issues typical of a neighborhood setting, as evidenced by multiple 311 calls in recent years. The most recent incidents include reports of garbage and debris (September 2024) and an abandoned vehicle (November 2024), both of which were resolved by the respective authorities. Between 2019 and 2024, there have been several parking-related complaints, including reports of vehicles blocking driveways and parking on sidewalks, though officers were generally unable to locate the offending vehicles. The building has also faced minor vandalism, including graffiti in January 2019, which was addressed. Historical permit records show limited modifications to the building's structure, with only basic maintenance and service upgrades documented in the last three decades.

Risk rating

How 311-313 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.

Neighborhood percentile
55th percentile

Out of 2250 buildings in this neighborhood, 1012 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 75.6%
Moderate concern 19.9%
Severe concern 4.5%
