Initial analysis

This two-story, three-unit multi-family residential building located at 163 23rd Ave in the Lake-The Presidio neighborhood was built in 1908 and is currently owned by Wsfs Family Inc. The property has undergone some recent maintenance work, with a reroofing project involving resheeting with 1/2 plywood and rerooking permitted at a cost of $9,000 in August 2023. However, there have been several concerning issues documented over the years. In August 2023, a complaint was filed regarding roof work being done with potentially unsafe wooden scaffolding, though the complaint was marked as not active. In 2014, there was a complaint about mold in the living room windows and bedroom walls, as well as issues with damaged stairs, which no longer appears as an active violation. A more serious building violation was recorded in 2002 concerning handrail repairs, which was not abated until 2018 and included a director hearing in 2003.

The building's recent history has been relatively stable, with the most significant recent activity being the roofing work in 2023. The property has experienced multiple parking-related incidents in the surrounding area, particularly between 2022 and 2024, including several reports of illegal parking, sidewalk parking, and abandoned vehicles, though these are external to the building itself. The majority of these parking violations were resolved through citations or officer response, and some were logged for data collection purposes. The building's maintenance history shows periodic attention to infrastructure needs, though the presence of mold and handrail issues in the past suggests there have been periods requiring significant attention to resident safety and comfort.

Risk rating

How 163 23Rd 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
16th percentile

Out of 660 buildings in this neighborhood, 554 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

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.

12-Month severity forecast

Moderate concern 35.2%
Severe concern 3.7%
