Initial analysis

The three-story, four-unit multi-family residential building at 740-744 Lake Street, owned by Norbert F & Heidy Lee, was constructed in 1904 and is classified as an apartment building. The property has experienced several notable issues in recent years, with the most significant currently active complaint filed in July 2024 alleging unauthorized construction work, including exposed wiring and electrical work being performed without permits. This follows a pattern of permit-related concerns, including a March 2017 complaint about unpermitted construction work involving a sliding glass door replacement. The building underwent routine housing inspections in 2003, 2008, and 1995, with the 2008 inspection revealing multiple violations including the need for handrails and gas meter safety instructions, though these were abated by May 2008. A plumbing permit from 2009 related to sewer and house trap work is recorded as expired.

The building's maintenance history shows some interior issues, including a 2015 complaint about mold and rust in the bathroom. More recent concerns have included a 2020 complaint about rodent or insect infestation (though determined not to be a response priority) and an ongoing June 2024 sidewalk defect issue reported through 311. The property has generated multiple 311 calls regarding general building issues, though most recent calls from 2022-2024 have primarily concerned external matters such as park maintenance and street cleaning. While the building has undergone periodic inspections and maintained a basic level of compliance, the pattern of recent complaints regarding unpermitted work and maintenance issues suggests ongoing challenges with property upkeep and regulatory compliance.

Risk rating

How 740-744 Lake 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
27th percentile

Out of 660 buildings in this neighborhood, 482 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 69.2%
Moderate concern 19.6%
Severe concern 11.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
