Initial analysis

The 12-unit multi-family residential building at 550 Baker Street, owned by Corbin Diana C, has experienced several significant issues in recent years, with the most pressing concerns being persistent rodent infestations in 2024, multiple fire safety violations, and various maintenance problems. The building underwent major renovations in late 2023 (completed in December), including a substantial $90,000 project in Unit 3 that involved converting existing spaces, rehabilitating bathrooms, and extensive electrical/plumbing work. While the building completed its required soft-story retrofit compliance in 2014, it has faced recurring fire safety inspection issues, with violations for extinguishers and alarm systems issued in 2024, and a pattern of fire safety concerns dating back to 2020.

The property has a documented history of multiple maintenance and safety issues, particularly during 2020-2024, including complaints about electrical problems (non-working outlets), heating system concerns, and various building maintenance deficiencies such as damaged walls, plumbing issues, and the presence of peeling paint. Tenants have reported persistent rodent problems, with multiple complaints about infestations, particularly in 2024. The recent 2023-2024 renovations suggest ongoing efforts to improve the building, though the timing coincides with continued maintenance challenges. The building has also experienced multiple garbage and debris incidents on the premises, with several 311 calls for cleanup in 2024, and issues with the fire escape access reported in 2020. While some violations have been promptly addressed and marked as "Corrected" or "Abated," the recurring pattern of similar issues suggests ongoing maintenance challenges within the property.

Risk rating

How 550 Baker 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 797 buildings in this neighborhood, 773 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.

Number of units

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

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 15.4%
Moderate concern 55.8%
Severe concern 28.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
