Who permits the work
Silver Spring is unincorporated Montgomery County — despite how it is talked about, there is no city government issuing permits. Everything goes through Montgomery County Department of Permitting Services, including the separate electrical permit the county requires for any circuit work. The one local wrinkle worth knowing: the neighbouring towns of Takoma Park and Kensington DO run their own review, so if your address straddles that line the answer to “who permits this” changes with the street.
For a rooftop array that generally means two permits rather than one: a building permit for anything fastened to the roof
structure, and a separate electrical permit for everything downstream of it, pulled by the licensed electrician on the job. We
sequence both and pull the building permit under our licence — you file nothing yourself.
What Silver Spring homes are actually built like
Silver Spring is one of the older housing stocks in the county — large numbers of 1920s–1950s bungalows, capes and brick colonials, plus mid-century ramblers further out.
For solar that matters in two specific places: the age and condition of the roof covering, which decides whether the array
goes on now or after a replacement, and the capacity of the electrical service, which a licensed electrician confirms before
anything is designed.
What we will not tell you about your Silver Spring project
No production figure, no payback year, no incentive percentage and no equipment warranty term. Those depend on your roof,
your bills, your tax position and programmes that change — and a number published before anyone has measured your roof is
a guess. Your specialist puts the real ones in writing after the free assessment, and tells you to confirm anything
tax-related with your own tax adviser.
Permit authority and code requirements are summarized for general guidance and can change; we confirm the current requirements for your specific parcel before work begins. Nothing on this page is tax advice.
