General liability insurance
Building design businesses pay an average of $38 per month, or $460 annually, for general liability insurance.

Policy limits impact the cost of general liability insurance
Policy limits are the maximum amounts your insurance company will pay for covered claims.
The per-occurrence limit is the most your insurer will pay for a single incident, while the aggregate limit is the maximum your insurer will pay on any claims during your policy period, typically one year.
Most building design businesses (85%) choose general liability policies with a $1 million per-occurrence limit and a $2 million aggregate limit. As your small business grows, you may need to expand your policy limits.
Business owner’s policy
Building design professionals pay an average of $67 per month, or $804 annually, for a business owner’s policy.
A business owner's policy, or BOP, bundles general liability coverage with commercial property insurance to cover both third-party risks and your business property. It typically costs less than purchasing the policies separately.
A BOP protects against customer injuries and property damage. It also covers damage to your physical building and design equipment and inventory. Because of its increased coverage and affordability, it’s the policy most often recommended by Insureon’s agents.
This is the average BOP for building design businesses that buy from Insureon:
Insurance premium: $67 per month
Policy limits: $1 million per occurrence; $2 million aggregate
Deductible: $500
Small, low-risk building design companies are often eligible for a business owner's policy.
Building design business owners may see higher costs if they choose to add endorsements to their policy. Insurance endorsements, such as business interruption insurance or equipment breakdown coverage, are often recommended to help avoid financial losses if a fire or power outage forces your business operations to cease for an extended period of time.
The cost of a business owner's policy is based on a number of factors, including the value of your property, where you are located, the number of employees you have, and your specialty.
Business property value drives the cost of a BOP
Among building design businesses that purchase a business owner’s policy with Insureon, 29% pay less than $50 per month and 70% pay less than $100 per month.
Businesses with a large office or more expensive business property will typically pay more for a BOP than building design businesses with smaller premises or lower value business property. Your industry risk, years in operation, and claims history will also affect your premium.


Professional liability insurance
Building design businesses pay an average of $144 per month, or $1,727 annually, for professional liability insurance. This policy is sometimes referred to as errors and omissions insurance (E&O).
Professional liability insurance offers critical coverage for building design professionals, including paying for legal fees related to accusations of professional negligence. For example, if an architect makes an error in a blueprint, this policy would cover the costs of a resulting lawsuit.
This is the average professional liability insurance policy for building design businesses that buy from Insureon:
Insurance premium: $144 per month
Policy limits: $1 million per occurrence; $1 million aggregate
Deductible: $2,000
The cost of professional liability insurance for building design professionals depends on several factors, such as your line of work, claims history and the policy limits you choose.
Your level of risk affects the cost of professional liability
Among building design businesses that get professional liability coverage with Insureon, 35% pay less than $100 per month and 64% pay less than $200 per month.
Building design professionals who have been sued in the past or own a large company may pay more for this insurance coverage. Providers will also look at the type of professional services you offer when determining your premium.

Your profession influences the cost of a professional liability policy
Professional liability insurance costs vary significantly among building design professionals.
In professions where work mistakes can have serious financial repercussions for a client, such as a system integrator overlooking a control system, you can expect to pay more for this policy compared to lower risk professions, like interior designers.

Common professional liability limits for building design businesses
Policy limits determine how much your insurer will pay on covered claims.
Most building design businesses (62%) choose professional liability policies with a $1 million per-occurrence limit and a $1 million aggregate limit.
As your small business grows, you may need to increase your policy limits for full coverage.

Workers’ compensation insurance
For building design companies, workers’ compensation insurance costs an average of $50 per month, or $601 annually.
This type of business insurance coverage helps pay for medical expenses when an employee is injured or gets ill on the job. It also provides disability benefits while they're recovering and unable to work.
To comply with your state’s requirements and avoid penalties, building design businesses typically must purchase this coverage for their employees. It's also recommended for sole proprietors, as health insurance plans can deny claims for medical bills when an injury or illness is related to your job.
Most policies include employer's liability insurance, which covers the cost of lawsuits related to employee injuries. There's usually no limit to how much a workers' comp policy can pay for employee benefits, though it depends on state laws.
The cost of workers' compensation insurance depends on several factors, including the number of employees you have and the level of risk involved with their jobs.

Cyber insurance
Building design business owners pay an average of $81 per month, or $975 annually, for cyber insurance. You might also see this policy called cyber liability insurance or cybersecurity insurance.
Cyber insurance helps building design businesses recover financially after a data breach or cyberattack. It can help pay for customer notification costs, fraud monitoring services, and other expenses necessitated by state data breach laws.
The cost of cyber insurance depends on the amount of personal information handled by your building design business, such as customer credit card numbers, along with the number of employees who can access that information.
Commercial auto insurance
Building design professionals pay an average of $230 per month, or $2,755 annually, for commercial auto insurance.
Most states require this coverage for vehicles owned by a building design business. For personal, rented, and leased vehicles used by your business, look to hired and non-owned auto insurance (HNOA) instead.
A commercial auto policy provides financial protection in the event of an accident involving your business vehicle. It can help pay for property damage, medical costs, and legal expenses.
The cost of commercial auto insurance depends on several factors, including the policy limits you choose, coverage options, the value of the vehicles, the driving records of anyone permitted to drive, and any additional insured endorsements.

Key factors influencing policy costs
Your insurance provider calculates your building design business insurance costs based on a number of factors, including:
- Industry and trade: Industries or trades with bigger risks, such as architects or engineers, will have more costly premiums than lower-risk professions like interior designers or building inspectors.
- Business equipment and property: High-value equipment will cost more to insure than lower-cost items. Also, equipment that is used more frequently tends to cost more to cover than infrequently used items.
- Business size and annual revenue: Insurance companies assume businesses that earn more money face increased industry exposure, which results in higher premiums.
- Location: Businesses in areas prone to natural disasters, increased foot traffic, or high crime rates may have to pay higher premiums than other businesses.
- Number of employees: The more employees or contractors that are on staff, the more opportunities there are for accidents to happen or for potential damage to occur to someone else's property.
- Types of insurance coverage purchased: Building projects and clients that require additional policies, such as professional liability insurance, will result in higher premiums than basic coverage.
- Coverage limits and deductibles: Higher coverage limits and lower deductibles will typically increase your premiums, while lower limits and higher deductibles can help keep insurance rates low.
- Claims history: A business with a list of previous insurance claims will likely pay more for insurance than a company with a clean history. Your credit history and business financials may be another factor that insurance carriers consider, especially for newer building design companies.
