Initial analysis

The two-unit residential building at 819-821 Fell Street, located in Hayes Valley and built in 1900, has undergone several significant improvements and faced notable challenges over its history. Most recently, in 2018, the property underwent substantial renovations including an upper unit kitchen remodel costing over $38,000, followed by additional modifications to remove a non-bearing wall in the second-floor kitchen, with associated plumbing and electrical work including a tank-less water heater installation and kitchen re-wiring. These improvements appear to have been completed successfully with all permits marked as complete.

The building's historical records reveal concerning conditions from 1994, when multiple safety hazards were documented in a complaint including issues with a glass door, unsafe stairway conditions, inadequate heating, electrical concerns, and security problems with doors. While this complaint was marked as abated in July 1994, there are no subsequent complaints on record regarding similar safety issues. The property has maintained its basic infrastructure, with a roofing project completed in 2008 costing $8,570. More recently, in 2024-2025, there have been several street-related service calls in the vicinity, including reports of garbage, debris, and sidewalk parking violations, though these issues appear to be related to public spaces rather than the building itself. A pattern of parking enforcement requests has been documented between 2022 and 2025, suggesting ongoing challenges with parking compliance in the area.

Risk rating

How 819-821 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
83th percentile

Out of 1027 buildings in this neighborhood, 175 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 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 84.8%
Moderate concern 9.5%
Severe concern 5.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
