Initial analysis

The 6-unit, 2-story multi-family residential building at 175 23rd Avenue, constructed in 1964 and currently owned by William Pacific Enterprises, has undergone several significant improvements and faced various compliance challenges over the past decades. Most recently, in October 2023, substantial updates are underway, including bathroom and kitchen remodeling ($55,000), electrical system upgrade from 60 to 100 amps, and associated plumbing work. The building previously completed important safety work, including a soft-story retrofit in 2017 ($150,000) to address seismic concerns, though it remains classified as non-compliant under Tier 3 status as of October 2023. Other notable improvements include window replacement in 2020 ($24,000) and comprehensive interior updates in 2016 ($28,000) featuring kitchen renovation, bathroom modifications, and electrical improvements.

The building's maintenance history reveals several tenant concerns that have been addressed over time, including heating system replacements (2015), fire safety violations in 2004 and 2015 that were subsequently abated, and various housing enforcement complaints related to heating, smoke detectors, and pest issues between 2004 and 2019. Parking enforcement records from 2021-2023 show multiple instances of driveway blocking difficulties, though these are external to the building itself. A minor cooking-related fire incident was recorded, but no civilian injuries were reported. While the building has generally received necessary updates and addressed safety concerns through various permits and improvements, the outstanding non-compliant soft-story status represents the most significant ongoing building code issue as of October 2023.

Risk rating

How 175 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
33th percentile

Out of 660 buildings in this neighborhood, 442 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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.

12-Month severity forecast
No violation 77.7%
Moderate concern 17.0%
Severe concern 5.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
