Initial analysis

The property at 231-233 Onondaga Avenue is a single-story, multi-family residential building constructed in 1912, consisting of two units in Mission Terrace. The building experienced a significant setback in May 2017 when a fire occurred, temporarily displacing tenants and causing substantial damage to the rear wall, stairs, roof, and interior areas. Following the incident, the building underwent extensive repairs in 2018, including work on the roof, electrical systems, and bathroom fixtures, with the fire damage repairs alone costing approximately $100,000. The building has been the subject of multiple permits in 2019 to legalize an additional ground floor unit, with these works valued at $150,000 each, though the active status of these permits should be verified.

Recent history shows the property has had recurring issues with garbage management, evidenced by multiple Recology reports of overflowing city garbage cans between 2022 and 2024. There have also been several parking-related complaints, including driveway blocking incidents in 2023. The building underwent a reroofing project in 2007, and there are ongoing efforts to comply with various city ordinances regarding unit legalization, with records indicating work was performed under Accessory Dwelling Unit regulations and other legalization efforts. The property's most recent planning records show completion of work to reduce an existing deck, infill a ground floor garage, and replace a dormer window, all completed by fSIA Consulting Corp.

Risk rating

How 231-233 Onondaga 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 149 buildings in this neighborhood, 1 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.

Neighborhood location

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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 85.9%
Moderate concern 10.5%
Severe concern 3.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
