Who permits the work
“Chevy Chase” covers several separately incorporated municipalities, and a number of them run their own building and permit review in addition to Montgomery County. Which village you are in changes who reviews your plans and what they care about — particularly for anything visible from 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 Chevy Chase homes are actually built like
The housing here is largely 1910s–1930s colonials, Tudors and Craftsman homes with plaster walls, original millwork worth protecting, and mechanical systems that have been added to rather than replaced.
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 Chevy Chase 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.
