Initial analysis

The 801-803 Clayton Street property is a three-story, 11-unit multi-family residential building constructed in 1900 and currently owned by Jason J & Caroline Sanders. The building has undergone several significant improvements and faced various challenges over its history. Most recently, in August 2023, the building received exterior improvements with the installation of fiber cement siding on a portion of the left wall. A major seismic improvement project was completed in 2022, involving mandatory soft-story retrofitting that cost approximately $30,000, following an initial $70,000 retrofit undertaken in 2018 as part of the San Francisco Mandatory Soft Story Retrofit Program.

The building's maintenance history shows regular electrical system upgrades, including a complete new electrical service installation in 2006 with 400-amp service and 14 meters. Several building violations and complaints have been recorded over the years, including three fire-related issues in 2006 involving smoke detectors, fire extinguishers, and enclosure door closers, all of which were abated by February 2007. The property has experienced recurring garbage and debris issues recently, with multiple reports in late 2024 regarding overflowing city garbage cans and abandoned waste. A recent fire violation was issued in November 2023 concerning sleeping area requirements. The building's inspection history includes routine apartment house inspections, a notable complaint in 1998 about possible illegal units, and various renovation works in 2003-2006 that included multiple kitchen and bathroom remodels.

Risk rating

How 801-803 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.

Neighborhood percentile
7th percentile

Out of 526 buildings in this neighborhood, 489 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.

Number of units

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

Building size

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

Neighborhood location

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

12-Month severity forecast
No violation 20.8%
Moderate concern 23.1%
Severe concern 56.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
