Your LLC name must be available
Your Interior Design LLC name must be unique in North Dakota's registry. A duplicate name gets your filing rejected. Northwest can form your LLC for $39 plus the $135 state fee, with your first year of registered agent service included.
Entity Decision
Do You Need an LLC to Run It?
You are not legally required to form an LLC. You can operate as a sole proprietor from day one. Most Interior Design owners form one for one reason: Interior designers specify products, oversee contractors, and make aesthetic decisions clients rely on. A renovation based on designer specifications that results in a $30,000 remediation creates professional liability claims.
As a sole proprietor, personal assets — savings, car, home — are directly exposed to any lawsuit or debt. An LLC creates a legal wall between you and your business.

Avoid These
Common Mistakes Interior Design Business Owners Make in North Dakota
- 1
Not using written design agreements with revision limits
Interior design projects expand in scope constantly without written agreements. Define the project scope, number of revisions, and change order process in writing.
- 2
Not disclosing trade discounts to clients
Many states require disclosure of trade discounts to clients. Undisclosed markups create professional liability claims.
- 3
Overselling what is achievable within a client's budget
Budget misalignment is the leading cause of client disputes in interior design. Set realistic expectations about what is achievable at the project's budget level.
- 4
Using your home address as your registered agent address
Your address appears in North Dakota's public LLC registry. A registered agent service keeps your home address off that registry.
- 5
Skipping the operating agreement
Some states require LLCs to adopt one, and without one your LLC follows the state's default rules. A basic agreement costs nothing to write.
- 6
Not separating business and personal finances
Mixing personal and business money makes it easier for a court to disregard your LLC's liability protection. Open a business bank account before your first invoice.
