Initial analysis

1128 Lake Street is a two-unit, two-story multi-family residential building located in San Francisco's Lake --The Presidio neighborhood. Built in 1900, this flats/duplex structure is currently owned by Dominic S. Chu and Wendy L. Fam. The building is undergoing significant transformation, with an active permit filed in December 2022 for redevelopment into a three-unit R2 building with an accessory dwelling unit, involving both horizontal and vertical additions, facade relocation, and installation of fire sprinklers. This project has received various approvals, including a rear yard variance allowing for a substantial 3,427 sq ft addition, and CEQA clearance has been issued. The redevelopment will increase Unit 1128's size from 685 to 762 square feet and Unit 1130's from 791 to 2,461 square feet.

The property has experienced multiple park-related maintenance issues between 2023-2024, primarily involving recreation equipment and structural maintenance in the surrounding area, including bathroom repairs, graffiti removal, and various other maintenance tasks, most of which have been resolved promptly. These issues appear to be primarily related to public park infrastructure rather than the residential building itself. The redevelopment project, though substantial, includes modern safety upgrades such as fire sprinklers, and has undergone thorough planning review processes, including discretionary review and public hearings, suggesting careful attention to regulatory requirements and community input. The building's historical preservation requirements were addressed during the project review process, indicating consideration for its architectural heritage.

Risk rating

How 1128 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

Model explanation

What's driving this score

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 75.9%
Moderate concern 20.5%
Severe concern 3.6%
