Initial analysis

The three-story multi-family residential building at 1021-1029 Oak Street in Hayes Valley, built in 1900 and currently owned by Lon Hardeman, has undergone significant maintenance and safety upgrades over recent years. Most notably, the building completed its mandatory soft-story retrofit in March 2018 at a cost of $30,000, achieving compliance with the San Francisco Building Code's earthquake safety requirements, and received its Certificate of Final Completion (CFC). Recent maintenance work includes addressing water leaks and bathroom repairs in November 2023 ($10,000) and dry rot repairs in December 2023 ($4,000), demonstrating ongoing attention to building upkeep.

The building's history includes several notable improvements and compliance issues. A new flat roof was installed in 2017 ($11,400), and the building's gas line was relocated by PG&E in 2014. In the early 2000s, the property faced multiple violations related to security and fire safety, including handrail issues and fire escape maintenance, though these were all abated by 2004. More recently, there have been recurring issues with bicycle lane blocking in the vicinity of the property, as evidenced by multiple 311 calls between 2022 and 2024, and one instance of a collapsed sidewalk related to a utility vault in 2022, which was resolved. The building's maintenance record shows regular attention to structural and safety requirements, with the most recent work focusing on preserving critical building elements like stairs and addressing water-related issues.

Risk rating

How 1021-1029 Oak St'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
74th percentile

Out of 1027 buildings in this neighborhood, 267 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

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 75.7%
Moderate concern 20.4%
Severe concern 4.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
