Wind Energy Systems

Your residential wind energy system will require permits and inspections in order to ensure that it is safe for use. We encourage you to review our small wind energy systems code and our small wind energy system permit application requirements before applying for a permit.

Please see the Maryland Energy Administration – Residential website and the – Tax Credits, Rebates & Savings website for more information.

Permits Required

Your residential wind energy system will require an electrical permit and a building permit. An electrical permit must be issued before the building permit is issued. If the system will power a hot water heater, a plumbing permit will be required and must be issued before the building permit. Please gather the documentation specified below and have your licensed electrician submit an electrical permit application. If applicable, have your licensed plumber submit a plumbing permit application, then submit a building permit application.

Permit Process

Many factors affect the speed with which your application(s) are approved. For best results, it is critical that you carefully review your application and design documents prior to submission to ensure that all necessary documents are included and that the design is compliant with county code. Normally, permits can be issued within 10-15 business days if the application is complete, accurate, and code-compliant.
