The City of Tucson passed Resolution No. 20193 on September 27, 2005, to encourage the installation of solar energy systems throughout the city. The resolution established a policy whereby the director of the Department of Planning and Development Services will waive the fee paid by an applicant for a permit for the installation of a qualifying solar system up to $1,000 for a single installation, or $5,000 for a subdivision or multiple project sites. Other resolutions have since been passed to maintain this permit fee waiver after its expiration.
