Do you have to get a special permit to build green?

Permits Needed to Build Green

You recycle everything from plastic bottles to shoe boxes and you wouldn't dare leave a room without first flipping off the light, so building a sustainable living or working space certainly suits your sensibilities. But how much will a permit cost, and how can it help a building achieve green certification?

The cost of a building permit for green construction is the same as one for traditional construction. Permit costs vary by city or county, but the cost of a permit is usually based on a percentage of the proposed project's value. In some cases, small home improvement projects like decks or room additions have a set fee for permits.

Although green building projects typically require the same permits as traditional construction, case-by-case reviews may be necessary if certain codes don't apply to a green building, says Meisel. For example, a traditional building permit may require a structure to have a certain number of dry wells -- subsurface storage repositories designed to dissipate excess water runoff -- per square foot, which doesn't make sense for a green building that captures rainwater for reuse and eliminates the need to manage it in the ground.

A permit also can help lead to future green certification. There are several green-certified building programs out there, but one of the most prevalent is the LEED program. Created by the U.S. Green Building Council and managed by the Green Building Certification Institute, LEED is a consensus-based rating system. "The goal is to continue to raise the standard for a green building and the LEED rating system," says Ted van der Linden, director of sustainability for DPR Construction.

To gain LEED certification, the builder or owner hires an independent third party to perform a green building certification. "Green building certification is generally voluntary, although some states or local governments require it for their building projects or affordable housing developments," says Abe Kruger, author of "Green Building: Principles and Practices in Residential Construction."

A green-certified building owner may expect to receive financial incentives from governments, Samuel adds. These incentives may include tax credits or abatements, grant funding or low-interest loans. In addition, some municipalities may waive permit fees or expedite permit approvals for green projects.
