Architecture Firm Business Owners Policy (BOP): Pricing Methodology

How is Business Owners Policy (BOP) premium calculated for Architecture Firms?

Architecture Firms pay Business Owners Policy (BOP) priced per location + receipts band. The rate per unit is the multiplicand; your declared exposure is the multiplier. The product is your base premium before experience-modifier and schedule-rating adjustments.

Understanding the unit lets you ask the right questions at renewal: which exposure changed, what rate is being applied, and where the schedule credits or debits landed. Without that view, the renewal number arrives unexplained.

Why class codes matter for Architecture Firms Business Owners Policy (BOP) rating

Before any premium is calculated, the underwriter assigns a ISO classification to the architecture firm. That class determines the base rate per location + receipts band and constrains which carriers can quote at all. The class is set based on the predominant operation — what generates the largest share of revenue or payroll.

Mixed operations create classification challenges. A architecture firm that does multiple types of work may legitimately fit in two or three different classes, and the choice between them can swing premium 15-30%. Documenting the operation split clearly in the application reduces the risk of mis-classification.

Why two carriers price the same Architecture Firms risk differently on Business Owners Policy (BOP)

Architecture Firms accounts placed in the standard market typically see 3-6 competing quotes, each with its own rating math. The spread between cheapest and most expensive is rarely an error; it reflects each carrier's view of the segment's loss potential and its competitive strategy.

Within a single year, carrier appetite shifts. A carrier that was hungry for Architecture Firms in January may pull back by July if its loss experience deteriorates. This is why the same submission can produce different competitive landscapes depending on timing.

Where Architecture Firms accounts most often get over-rated on Business Owners Policy (BOP)
