Initial analysis

726 Oak Street is a two-story multi-family residential building constructed in 1965, containing 8 units and currently owned by the Man & Jeng family trust. The property has undergone several significant improvements in recent years, including a soft-story retrofit completed in 2017 (with a cost of $60,000) to meet seismic safety requirements, and ongoing unit renovations in 2024-2023. Unit #101 is currently being renovated with a kitchen and bathroom remodel ($75,775), while Unit #102 received similar upgrades in early 2023 ($25,000). These improvements include kitchen and bathroom renovations, electrical upgrades, and plumbing work. The building has a history of maintenance issues, most notably in 2006, when multiple violations were recorded regarding fire safety, security, plumbing, and interior surfaces, though all were abated by September 27, 2006. The property has also had regular routine safety inspections (2006, 2009, 2018), with the most recent fire alarm system violation in 2019 being corrected within weeks.

Historical maintenance records show earlier issues with deck repairs (1992), roof replacement (1989), and various safety improvements. Recent 311 calls from 2024 primarily relate to street-level issues near the property, including waste removal and sewer vent maintenance, though these are external to the building itself. The building's infrastructure improvements and consistent unit upgrades suggest active property management, with particular attention to seismic safety through the completed soft-story retrofit program. The most recent fire-related incident was a system alarm issue in 2023 that was promptly addressed. The building's permit history indicates ongoing maintenance and improvement work, most recently focusing on modernizing individual units while maintaining original layouts.

Risk rating

How 726 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.

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.

Building size

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

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 50.6%
Moderate concern 21.6%
Severe concern 27.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
