Initial analysis

The two-unit residential building at 805-807 Clayton Street, constructed in 1910 and currently owned by Thanh Nguyen & Laura Ragsda, has undergone significant renovations over recent years, with particular emphasis on safety upgrades and energy improvements. Most notably, the property has received comprehensive fire safety enhancements, including the installation of a complete fire sprinkler system in 2022 (costing $41,500) and subsequent expansions in 2023 and 2024 to improve monitoring and heat detection capabilities. Energy improvements have included the installation of a solar PV system (9.6 kW) and battery storage system (20 kWh) in 2022, followed by electrical service upgrades to 300A with two meters in late 2023. Recent mechanical upgrades include the installation of two new ductless heat pump systems in 2024.

The building has experienced various construction-related issues, particularly during 2021-2024, including multiple complaints about work being done beyond permit scope, sidewalk obstructions, and concerns about lead paint handling. Notable complaints in early 2022 centered on perceived height violations during renovation work, and there were several complaints in late 2023-early 2024 regarding construction impacts on pedestrian safety and building access. Several plumbing improvements have been completed in 2023-2024, including extensive bathroom and utility upgrades, and the property has also seen significant structural work including basement modifications and retaining wall adjustments. Historical records show that the building previously had violations related to stairs repair and lead paint concerns in 2008, which were abated by 2012, and there were two fire-related complaints in 2011, both deemed to have no merit. The most recent activity as of 2024 includes ongoing electrical rewiring work and various utility upgrades.

Risk rating

How 805-807 Clayton 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.
