What are the six main types of architectural practice ownership?

Sole proprietorships represent one of the foundational types of business structures in architectural practice ownership. In this model, an individual owns and operates the firm independently, having full control over decision-making processes, management, and the distribution of profits. This form of ownership is particularly common in architecture because it allows for a direct relationship between the architect and their clients, fostering a personalized approach to service delivery.

This type of ownership is characterized by its simplicity in terms of setup and operational flexibility. Sole proprietors have fewer regulatory burdens compared to other ownership structures like corporations or partnerships, making it an appealing choice for many architects, especially those starting their careers or operating on a smaller scale.

In contrast, the other mentioned options, such as cooperatives, limited liability companies, and multi-disciplinary firms, introduce varying complexities in their structure and function. While these models offer advantages like shared risk, pooled resources, or collaboration across disciplines, they do not catch the essence of the traditional single-owner practice that is fundamental to much of the architectural profession. Thus, sole proprietorships stand out as a primary mode of practice ownership within the field of architecture.
