Initial analysis

1855 Clay Street is a 3-story, 6-unit multi-family residential building constructed in 1918, currently owned by Harris Matsue M & Shimao Ka. The building has undergone significant improvements over the past decade, including the installation of a comprehensive fire sprinkler system in 2013 and a solar PV system in 2017 consisting of 14 modules with a total rating of 3.92kW. Recent electrical upgrades include the installation of heaters in 2018-2019. A notable compliance issue arose in 2018 regarding inadequate heating, which prompted violations related to maintaining required room temperatures and heat availability, though these were eventually abated by December 2018. The building has experienced recurring fire alarm system maintenance issues, with violations recorded in 2018, 2019, and most recently in August 2023, though the conditions were corrected or abated.

The property has undergone various infrastructure improvements, including relocation of exterior stairs in 2014 and multiple plumbing upgrades between 2009 and 2014 involving water heaters, gas lines, and drainage systems. A significant series of complaints and violations from 2002, primarily related to building maintenance, fire safety, and heating requirements, were resolved by 2018. The building's recent history shows regular maintenance and upgrades, though there have been periodic issues with the fire alarm system and heating compliance. Tenants have experienced some disturbances from nearby construction (2012) and parking issues around the property, as documented in multiple 311 calls for parking enforcement between 2023-2024. The property's maintenance and improvement record suggests ongoing efforts to address both regulatory requirements and tenant comfort, despite some recurring system-related issues.

Risk rating

How 1855 Clay 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
36th percentile

Out of 963 buildings in this neighborhood, 616 are predicted to be safer.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 37.3%
Moderate concern 32.0%
Severe concern 30.7%
