Initial analysis

The property at 741-743 Oak Street is a three-story, two-unit multi-family residential building located in Hayes Valley, built in 1900 and currently owned by Clark Lauren Evelyn. The building has undergone significant improvements over recent years, with the most substantial renovation occurring in 2021-2022, which included comprehensive kitchen and bathroom remodels in both units ($160,000), plus the installation of new furnaces and a gas water heater. These renovations also encompassed adding 84 square feet of habitable space, installing new windows and a French door at the rear, and included extensive electrical and plumbing work across both units. Prior to this, the building underwent necessary compliance work in 2020 addressing an R-3 physical inspection report (CC-8417), including electrical, plumbing, and general repairs costing $18,000.

The building has a history of regular maintenance and upgrades, including a new roof installation in 2013 ($13,000), window replacements in 2012, and historical stair repairs in 1989. While there was one housing code violation complaint filed and quickly resolved in 1994, there have been no subsequent building code issues on record. Recent 311 calls primarily relate to street-related matters such as parking enforcement and sidewalk issues, with no direct impact on the building's condition or resident safety. The property's maintenance record suggests regular upkeep, with significant investments in modernizing both units and addressing maintenance requirements as they arise. The most recent plumbing work, completed in September 2024, involved the replacement of a 40-gallon gas water heater, indicating ongoing system maintenance.

Risk rating

How 741-743 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

Out of 1027 buildings in this neighborhood, 31 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.

Building size

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 89.8%
Moderate concern 7.1%
Severe concern 3.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
