Chapel Hill, NC Building Safety: Green Building Code (2026)

Article VII of the Code of Ordinances, adopted in 1997 and last amended in 2018, commits the Town of Chapel Hill to building its own facilities to a green standard. Section 5-122 requires any new or expanded town building meeting the applicability threshold to employ the Leadership in Energy and Environmental Design (LEED) Green Building Rating System and the Architecture 2030 Challenge's fossil-fuel energy reduction targets throughout design, construction, and operation, achieving at least LEED silver certification unless the council grants a waiver. Section 5-123 sets that threshold at five thousand square feet of gross occupied area for new construction or additions; renovated buildings with additions of that size need only meet half of the applicable Architecture 2030 reduction target, and the council may extend the LEED silver requirement to smaller additions at its discretion.

The article does not reach retrofits of existing town buildings or public housing construction, though the council encourages LEED principles there too. Section 5-124 lets the council waive the LEED silver standard or the Architecture 2030 target if a LEED professional or project architect determines meeting it would add more than seven percent to project costs. Section 5-125 requires the design team to include a LEED-accredited architect or engineer directly managing the project day to day, and section 5-126 requires the project architect or engineer to monitor the building's energy performance for its first year and produce a commissioning plan, with results reported annually to council.
