Water & Energy Conservation

Mandatory Design Features

In most desert climates, the sun is the most plentiful commodity and water is the most valuable resource. The City of Tucson has made these two elements of significant concern by adopting a few ordinances to ensure sustainable potential in the future.

Residential Green Building Rating System

The City of Tucson certifies two types of residential projects. Certificates are available for new one and two family dwellings or extensive residential remodels/additions. In order to participate in the program, an applicant must submit a completed checklist with supporting documentation in conjunction with a permit application. Building design is evaluated in the following six categories:

Location, Lot Design, Preparation & Development
Can your project be constructed with minimal impact to the land and maximize natural landscaping consistent with the local region?
Resource Efficiency
Are you making the best use of the building materials available for construction?
Energy Efficiency
All buildings consume energy in order to provide a comfortable living environment. How much energy will your residence require?
Water Efficiency
Does your construction design incorporate the best use of our desert’s most precious resource?
Indoor Environmental Quality
A home is intended to provide a safe and relaxing environment for our families and the best design would avoid harmful chemicals and provide a healthy atmosphere.
Operation, Maintenance & Owner Education
The best tools have little value when used erroneously. Will you be setting the homeowner up for success by teaching them about the sustainable elements of the home?
