Home Additions · Ashton
Why Ashton homeowners hire us.
An Ashton addition is planned for the Ashton-Sandy Spring community along MD 108, and the parcel stays with Montgomery County rather than a town hall.
Ashton-Sandy Spring is a census designated place, census place 2402762, and not an incorporated town. The American Community Survey 2024 five-year estimates for that place show a median owner-occupied value of $809,200 and a median year built of 1986.
When the work does not conform to the 2021 International Residential Code, or it is attached to a townhouse, or it is unusual or complex, the county requires construction drawings signed and sealed by an architect or professional engineer, with the seal, signature, date, and certification statement. The Ashton addition price is a free written estimate after a site walk.
For this area, see Permits in Montgomery County: what to expect.
Addition drawing set
The architectural set for an Ashton addition includes existing and proposed floor plans, the use of each space, means of egress, floor-by-floor square footage of added and altered space, and locations of smoke and carbon monoxide alarms. The fast-track clock for eligible small projects is a separate guide, and an addition is not on that list.

Questions about home additions in Ashton
Who permits a home addition in Ashton?+
Ashton is not on Montgomery County's municipalities list, so the addition does not start at a Rockville, Gaithersburg, Takoma Park, Garrett Park, Kensington, Brookeville, Laytonsville, or Barnesville counter. Montgomery County Department of Permitting Services is the building office. General permit questions go to 240-777-0311. An Ashton addition is outside the residential fast-track list.
When does an Ashton addition need a drainage plan?+
A drainage plan is required before a permit when an addition increases the building footprint by more than 400 square feet, on a residential lot under 15,000 square feet, and a stormwater management plan has not already been approved. Measure outside wall to outside wall. Electrical, plumbing, and HVAC on the addition are licensed trades Real Elite coordinates and does not self-perform.
