Which document outlines the fundamental rules for the operation of a condominium?

The bylaws of a condominium are essential as they establish the fundamental rules and regulations governing the operation and management of the condominium association. These rules dictate how the association will conduct its business, including the procedures for meetings, voting rights, maintenance responsibilities, and other governance-related issues. The bylaws provide the framework for the administration of the condominium, ensuring that all unit owners and the association operate under a consistent set of guidelines and expectations.

While the declaration is a crucial document that describes the condominium's structure and ownership, it primarily details the property boundaries, the units included, and the common areas. The operating agreement typically relates more to partnerships or limited liability companies and is not specific to condominium governance. A lease agreement pertains to the rental of individual units and does not govern the overall operation of the condominium community.

Thus, the bylaws are the correct choice as they encompass the governance and operational rules necessary for the effective management of a condominium.
