Quick Answer
Earthship homes are not subject to conventional building codes, but rather follow the International Building Code (IBC) and International Residential Code (IRC) with modifications and waivers. The Earthship Community in Taos, New Mexico, has developed its own set of standards and guidelines. Local jurisdictions may adopt these standards or modify the IBC and IRC to accommodate Earthship construction.
Earthship Building Standards
Earthship homes, developed by architect Michael Reynolds, are designed to be off-grid and sustainable. They are constructed using recycled and natural materials, such as tires and earth, to minimize waste and environmental impact. Earthship homes are typically built in a series of modules, with each module consisting of a tire wall, a roof, and a floor. The tire walls are typically 12 feet tall and 6 feet wide, with 12-14 tires per wall.
Modifications to Building Codes
The Earthship Community in Taos, New Mexico, has developed a set of standards and guidelines that deviate from the IBC and IRC. For example, Earthship homes are allowed to exceed the maximum height of 45 feet set by the IRC, as long as they are designed to resist wind loads and other external forces. Additionally, Earthship homes are allowed to use a variety of unorthodox building materials, such as tires and cans, which are not typically permitted by conventional building codes.
Local Regulation and Approval
Local jurisdictions may adopt the Earthship Community’s standards and guidelines or modify the IBC and IRC to accommodate Earthship construction. Earthship builders typically work with local building officials to obtain waivers and permits for their projects. This process can be time-consuming and requires careful planning and documentation to ensure compliance with local regulations.
