Architecture firm insurance is dominated by professional liability — Insureon shows GL at $34/month but professional liability averaging $150/month. The premium reflects long-tail completed-projects exposure: design errors discovered years after construction can still trigger claims.
Most architecture firms pay about $34 a month for general liability and $72 a month for a business owner's policy (BOP), based on Insureon's figures for its own customers.
Price is one part of it. Our architects insurance guide covers which policies you need and why.

- Document client decision-making and change orders thoroughly
- Maintain detailed project files for completed-projects defense
- Bundle GL + property in a BOP, separate professional liability with a design-specialist carrier
- Quote design-specialist carriers (Victor, Travelers Design Professional, Berkley DP)
Frequently Asked Questions
How much does architect insurance cost?
Per Insureon's 2026 data, general liability averages $34/month ($404/year), a business owners policy averages $72/month, workers' compensation runs $50/month. Total premium depends on revenue, employees, state, and claims history.
What insurance do I need as a architect?
Most architecture firms need: general liability (often bundled into a business owners policy), workers' compensation once you have any employees, professional liability (E&O) if you provide advice or deliverables. The specific mix depends on your operations, employee count, and any contractual requirements from clients or vendors.
How long does it take architecture firms to get insurance quotes?
It depends on how many policies architecture firms need and how quickly you can supply the details. Chubb says a basic online quote often takes only a few minutes for a simple business. Workers' comp takes longer to price because the insurer needs your payroll for each type of job. Professional liability usually needs a short application about the services you provide and any past claims. Having these details ready is the fastest way to get quotes; see what you need for a business insurance quote.
Should architecture firms buy insurance direct or through an agent?
Either can work for architecture firms. Buying direct from an insurer online suits a simple business that needs one or two policies. An agent or broker who compares several insurers helps most when you have employees and need workers' comp, because you are buying several policies at once. Neither route is cheaper by default: each insurer prices its own business types and states, so comparing quotes is the only way to know.
Why is architect professional liability so much more expensive than GL?
Design errors create high-dollar exposure. A structural design flaw, a code violation missed in the drawings, or a coordination error between disciplines can produce six- and seven-figure claims that follow the architect for years (the 'long-tail' nature of design liability). Insureon shows architect PL averaging $150/month vs $34 for GL.
How long does architect professional liability exposure last?
State statutes of repose for design professional liability run for a set number of years after substantial completion of the project, and the period varies by state. This means architects need 'tail coverage' (extended reporting period) when they retire or change carriers — a claim filed years after a project completes can still trigger coverage if you had policies in force during the project. Most architect E&O is claims-made, requiring continuous coverage.
