Summary

Asheville does not run a mandatory green building code, but its zoning ordinance rewards LEED and NC Healthy Built Homes certification. Under UDO Sec. 7-16-1(69)f, a sustainable development project can add 10 feet of building height for LEED Silver, or cut lot size, width and setbacks by 30 percent for LEED Bronze.

4. Height maximums may be extended an additional 10 feet if 100 percent of the units are affordable or if Silver, or higher, LEED certification is achieved. 5. Lot sizes, widths, and setbacks may be reduced by 30 percent if no density bonuses are being sought and the project meets Bronze (or higher) LEED certification or NC Healthy Built Homes certification.

Full Breakdown

Asheville's Unified Development Ordinance folds its green-building incentive into the "sustainable development projects" use-by-right category rather than a separate green building code chapter. Sec. 4 lets a project add 10 feet to the otherwise applicable height maximum if either 100 percent of the units are affordable, or the project achieves LEED Silver certification or higher. Sec. 5 offers a separate, non-stacking incentive: if a project is not seeking a density bonus at all, it can instead reduce its minimum lot sizes, lot widths, and setbacks by 30 percent by meeting LEED Bronze certification (or higher) or NC Healthy Built Homes certification.

Both incentives sit inside the broader sustainable development standards in subsection (c), which require every unit in the qualifying project to be Energy Star Certified, and which require the project to sit within one-eighth of a mile of a designated high-frequency transit corridor and keep 75 percent of the project area, including grading, inside the mapped eligibility area. Because the height and dimensional bonuses are keyed to third-party certification (LEED or NC Healthy Built Homes) rather than a locally administered green building code, the Planning and Development Department verifies eligibility through the certification body's documentation rather than through a city-run green-building inspection program.

Violations & Fines

There is no separate penalty schedule tied to the LEED bonus itself; the consequence for failing to actually achieve the claimed certification is loss of the height or dimensional allowance granted under Sec. 7-16-1(69)f. A project that used the extra 10 feet of height or the 30 percent dimensional reduction without delivering the required LEED Silver, LEED Bronze, or NC Healthy Built Homes certification would be out of compliance with the special-requirement conditions that made the structure permissible in the first place, exposing it to code enforcement by the Planning and Development Department.

Frequently Asked Questions

Does Asheville have its own green building code?
No. Asheville enforces the state building code and instead uses zoning incentives to encourage green construction. Under UDO Sec. 7-16-1(69)f, a qualifying sustainable development project gets extra building height for LEED Silver certification or a dimensional reduction for LEED Bronze, rather than a separate mandatory green code.
How much extra height can a LEED-certified project get in Asheville?
Sec. 7-16-1(69)f.4 allows an additional 10 feet above the otherwise applicable height maximum if the project achieves LEED Silver certification or higher, or if 100 percent of its units are affordable. The two paths are alternatives, not cumulative requirements.
Can a project get both the density bonus and the LEED dimensional reduction?
No. Sec. 7-16-1(69)f.5 only allows the 30 percent reduction in lot size, width, and setbacks for LEED Bronze or NC Healthy Built Homes certification when the project is not seeking a density bonus under f.1. The two incentive paths are structured as alternatives.
