Initial analysis

The two-unit residential building at 339 Plymouth Ave in Oceanview, owned by Daisy Chiu Sim Chan, was constructed in 1900 as a two-story flats and duplex structure. The property has undergone several significant maintenance and infrastructure improvements over the years, with the most recent being a completed re-roofing project in October 2024 costing $10,000, following a 2014 re-roofing effort. The building experienced substantial plumbing work in 2007, including a 60-foot sewer line replacement and house trap installation, indicating attention to critical infrastructure systems. There have been multiple exterior maintenance activities, including rear building structure repairs and wood siding replacement in 1995.

The property has experienced several concerning incidents, including a 2014 complaint about a possible illegal unit in the rear yard, though this case is currently listed as not active. A notable fire-related complaint was filed in December 2015 and resolved the following month with conditions corrected. More recently, there has been a pattern of parking-related issues near the property, particularly in late 2023 and early 2024, with multiple citations issued for blocking driveways and parking on sidewalks. These parking violations, while not directly related to the building's condition, represent an ongoing issue in the immediate vicinity. The most recent maintenance and improvement history suggests regular upkeep of the building's essential systems, with particular attention to roofing and plumbing infrastructure.

Risk rating

How 339 Plymouth Ave'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
65th percentile

Out of 79 buildings in this neighborhood, 28 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 64.9%
Moderate concern 16.3%
Severe concern 18.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
