Initial analysis

The property at 408-410 Plymouth Avenue in the Oceanview neighborhood is a two-unit, two-story multi-family residential building constructed in 1948, currently owned by the Helen J Dilworth Trust 2010. The building has undergone several significant improvements over the past two decades, with the most recent major work being a kitchen remodel in 2019 valued at $25,000, which included extensive electrical and plumbing upgrades for modern appliances, lighting, and safety features. Prior improvements include a 2009 service upgrade with the installation of new electrical panels and grounding systems, and in 2015, both units received kitchen remodels and HVAC improvements including the installation of a new gas furnace. The building permits indicate proper administrative corrections were made in 2020 to address address discrepancies between the two units.

Of concern, there were two housing-related complaints filed in late 2015, one regarding alleged garbage accumulation in unit 410 and another reporting rodent issues with access points through wall holes, though both matters appear to have been resolved as they are now listed as not active. The only other incident on record is a vehicle impact damage repair from 1997, indicating that this was an isolated incident. The property has maintained regular updates and improvements to its infrastructure, particularly in terms of electrical systems and kitchen modernization, showing ongoing maintenance and upgrading of building systems.

Risk rating

How 408-410 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
