Initial analysis

This two-unit multi-family residential building located at 3621 Broderick Street in the Marina neighborhood was constructed in 1927 and is currently owned by Chou Shih Chung. The property has undergone several significant renovations over the past two decades, with the most recent work being a kitchen remodeling project completed in 2024, which included cabinet and countertop replacement ($24,663). The building's maintenance history shows regular attention to infrastructure, with a complete reroofing project in 2020 ($16,000) and various kitchen and bathroom remodeling projects between 2020-2024 totaling over $60,000. A notable incident occurred in 2013 regarding water heater safety violations, where issues with PVC flue termination and combustion air were documented, though these violations were abated by April 2014.

The property has shown consistent maintenance and improvement over the years, with multiple permits for kitchen and bathroom renovations, including updated plumbing and electrical systems. Historical records show attention to the rear deck area, with approved modifications to remove stairs at the second level while maintaining access through interior stairs. The building's permit and violation history suggests regular upkeep and responsiveness to building code requirements, with all recent permits marked as complete and no current active violations. The property has experienced typical urban maintenance issues as documented in 311 calls, primarily related to street and parking matters, but these are external to the building's condition or maintenance.

Risk rating

How 3621 Broderick 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.

Construction type: wood frame

Wood-frame construction (type D) is the most common SF residential type and has specific maintenance risks.

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

12-Month severity forecast
No violation 95.2%
Moderate concern 3.5%
Severe concern 1.3%
