Initial analysis

The property at 231-233 10th Avenue is a two-unit, two-story multi-family residential building located in the Inner Richmond neighborhood. Built in 1900, this flats/duplex structure underwent significant renovations in 2009, including comprehensive bathroom remodels on multiple floors, kitchen modifications, and living space reconfigurations, totaling over $210,000 in improvements. These renovations were initially completed without proper permits, leading to a Notice of Violation filed in May 2009, though the issues were subsequently addressed through proper permitting and inspections.

More recent building maintenance includes a street space permit issued in 2017 and plumbing work in 2023 involving sewer vent cover installation, though this permit has since expired. The property has undergone various infrastructure upgrades over the years, including electrical system improvements in 2006-2008 (200-amp service upgrade, sub-panel relocation) and plumbing updates in 2009 (new water service, tankless water heater installation). The building's maintenance history shows regular upkeep, though there have been multiple 311 calls regarding parking issues and street cleaning matters in recent years, particularly in 2022 through 2024. A planning record from 2020 clarified the building's status as a two-unit structure, despite some historical discrepancies in tax records.

Risk rating

How 231-233 10Th 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 1723 buildings in this neighborhood, 810 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.

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.

12-Month severity forecast
No violation 79.6%
Moderate concern 13.9%
Severe concern 6.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
