Initial analysis

The three-story multi-family residential building at 1909 Lake Street, located in the Lake - The Presidio neighborhood, was constructed in 1907 and contains 6 units. The building, currently owned by Geronima S Belen-bautista L, has undergone several significant maintenance updates, including a complete re-roofing project in 2015 costing $24,000, following a previous cancelled re-roofing permit from 2015, and an earlier re-roofing project in 1992. A notable infrastructure upgrade occurred in April 2023 with the replacement of the main sewer line. The building has experienced recurring moisture-related issues, with multiple violations and complaints related to mold and mildew documented between 2003 and 2009, including a 2003 incident involving both walls and ceilings, and a 2009 complaint about insufficient heat and leaks with resulting mold. The property has also experienced safety-related concerns, including several fire safety violations in 2003-2006 regarding fire escape maintenance and combustible storage, though these were addressed and abated by May 2003.

Most recently, in August 2020, there was a complaint regarding a foul smell coming from apartment #1, which was last observed to be persistent since approximately 2019. The building underwent routine inspections in 2003, 2006, and 2008, revealing various maintenance needs. Infrastructure improvements include both roofing and sewer line upgrades, though the building's history shows recurring moisture-related challenges. The property has generated multiple 311 calls, primarily relating to parking issues in recent years (2023-2024), with several citations issued for illegal parking. While many historical violation cases have been resolved, the property has a documented history of moisture problems, safety violations, and maintenance needs that have required periodic attention over the years.

Risk rating

How 1909 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

Out of 660 buildings in this neighborhood, 594 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.

Building age

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

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

12-Month severity forecast
No violation 43.6%
Moderate concern 47.2%
Severe concern 9.3%
