Full Breakdown
The Howard County Green Buildings Law is Subtitle 10 of Title 3 of the County Code. Section 3.1003 sets who is covered. Any new construction of a publicly funded building with 10,000 square feet or more of gross floor area must comply. A building counts as publicly funded when the County finances at least 30 percent of the cost of new construction, or of a lease longer than 20 years. Privately funded buildings are covered at 50,000 square feet of gross floor area, or 10,000 square feet inside Downtown Columbia, if they fall in Assembly A, Business B, Institutional I, Mercantile M, residential R-1 or R-2, or a mixed occupancy that is mostly one of those uses and is two stories or more.
Section 3.1003(b) carves out publicly funded E and I-3 buildings, privately funded R-2 buildings made up only of dwelling units and under five stories, buildings with no HVAC system, and any other category the Director sets by regulation. Renovations that do not change gross floor area are not new construction.
Section 3.1004 sets the standard. Publicly funded buildings must earn at least a silver rating from the U.S. Green Building Council under LEED 2009 New Construction or Core and Shell. Private buildings must earn at least certified level. The Director of the Department of Inspections, Licenses and Permits can adopt equivalent standards by regulation instead.
Section 3.1005 sets the paper trail. The site development plan application to the Director of Planning and Zoning needs proof of LEED registration and a checklist signed by a LEED accredited professional. The building permit application needs an updated checklist, bird-friendly design documentation under 2019 LEED Pilot Credit #55 or a Director-approved equivalent, and construction notes showing the green measures. Before a use and occupancy permit issues, a commissioning team must review the design. After the certificate of use and occupancy, the applicant has 12 months to apply for certification and 36 months to prove the rating was obtained.
Section 3.1006 gives expedited permit review to projects seeking gold or platinum. Section 3.1007 lets the Director waive the law only for unique physical site conditions, and financial hardship does not qualify. Non-public applicants with a waiver pay a per-square-foot fee-in-lieu, set by County Council resolution, before the permit is granted. Section 3.1008 holds those fees in a Green Building Fund that cannot revert to the general fund.
Violations & Fines
Section 3.1011 splits enforcement. Violations other than the section 3.1004 standard are enforced under the Howard County Building Code. For privately funded buildings, the Director can sue at law or equity, including injunction or mandamus, to enforce the 12-month certification application deadline in section 3.1005(e), and can pursue civil penalties under Title 24. A violation of that deadline is a Class A offense, and each day it continues is a separate offense. Publicly funded buildings are excluded from those civil remedies.
