Architectural Resources Group (or ARG; also known as Architects, Planners & Conservators, Inc.) is a firm founded in 1980 by Bruce Judd and Steve Farneth in San Francisco, California.

It began by providing professional services in the fields of architecture and urban planning with particular expertise in historic preservation.

Because of the complex range of issues common to preservation projects, the firm associates with consultants in diverse fields such as architectural history, preservation technology, building pathology, urban planning, building materials, engineering, real estate, and economics.

The firm and its projects have received more than 100 awards in design excellence, conservation, and planning, including those sponsored by the National Trust for Historic Preservation, the American Institute of Architects, the California Governor's Office, and the California Preservation Foundation.
