Initial analysis

The three-unit residential building at 820-824 Fell Street, owned by Michael Louis Probber, is a 3-story flats and duplex structure built in 1906 in the Alamo Square neighborhood. The building is currently undergoing a significant renovation, with a $429,000 project filed in October 2021 to remodel all three dwelling units plus the garage level. The property has undergone several important infrastructure improvements over the years, including foundation work in 2005 with the injection of 3,600 gallons of permeation grout under the east wall foundation. The building has had multiple routine safety inspections, with the most recent occurring in 2017, and several fire safety violations were recorded in 2002-2008 related to fire extinguishers and stair repairs, though these were all abated by March 2003.

Recent improvements include the installation of a solar PV system completed in September 2023, consisting of 5,660 modules with a total capacity of 12.4 kW DC. The property has experienced consistent issues with blocked driveways in recent months, with ten such complaints recorded between October 2024 and January 2025, though most of these were unable to be verified by responding officers. The building's fire alarm system has had several malfunction incidents recorded, none resulting in actual fires or injuries. Additionally, a tenant buyout occurred in March 2021 for $50,000, affecting one tenant, and there are ongoing maintenance matters being addressed, including an open case for an overgrown tree as of December 2024. The property underwent a substantial interior remodel in 2021 that included elevator installation and lightwell modifications, though these changes were designed to be minimally visible from the street.

Risk rating

How 820-824 Fell 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

Out of 305 buildings in this neighborhood, 40 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.

Building size

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

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 69.9%
Moderate concern 24.7%
Severe concern 5.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
