Architectural fees vary according to the project’s scope, complexity, size, level of customization, permitting needs, consultant coordination, and construction involvement. Ortiz Mexia Projects, Inc. does not publish standard pricing because each residential project is different. A consultation can clarify the intended work, services required, and the factors that will shape a project-specific proposal.
