The full picture.
Firm registration basics
Architecture firms must register with the state architecture board in each state where they practice. Registration confirms: ownership structure compliant with state law, designated responsible architect, firm name complies with naming rules.
Ownership requirements
Most states require majority (51%+) ownership by licensed architects. Some states require 100% ownership. A few states (Colorado, others) allow more flexible ownership with at least one licensed architect on staff.
Entity structure
Most states require PLLC or Professional Corporation. Standard LLC typically not permitted for architecture practice. PLLC formation includes board approval in some states.
Designated responsible architect
Most firms must designate a licensed architect responsible for the firm's professional work. This architect signs and seals drawings on behalf of the firm.
Firm naming rules
Many states have specific rules: name must include "Architects" or "Architecture" or initials; some prohibit non-architect names; some require all named partners to be licensed.
Multi-state operations
National Council of Architectural Registration Boards (NCARB) facilitates individual architect licensure through state reciprocity. Firm licensure must be separately obtained in each state.
Continuing requirements
Annual firm registration renewal; individual architect license renewal with continuing education; periodic audits or audits-on-demand by state boards.
Common firm structures
Sole practitioner PLLC: single-architect firm. Multi-architect PLLC: 51%+ architects own. Corporation: less common; subject to similar rules.
Common compliance issues
Operating without firm registration; using a firm name that violates rules; allowing unlicensed individuals to sign drawings; majority ownership shifting below 51%.
