Montgomery County says a residential fast-track application is filed online and is generally issued in one to two business days. The county's examples include a single-level deck and a shed under 200 square feet. On a standard residential building application, the first set of review comments typically takes four weeks. An addition, a screened porch, and a two-level deck stay off the fast-track list. A house on a private well or a private septic system cannot use that track. That is the county's description, not a promise that one Ashton or Olney house qualifies.
Montgomery County Department of Permitting Services describes a shorter clock for some residential permits and a longer one for a standard residential building application. The note is the Residential Fast Track Permit Process. Real Elite read the Montgomery County fast-track page on October 14, 2026. A supporting eligibility sheet dated August 25, 2023, was read the same day. This guide is for Ashton and Olney homeowners before they hire. It is not a promise that a specific house qualifies.
What the county says about the clock
Fast-track residential applications have to be filed online. The county's usual timing for that path is one to two business days. The eligibility sheet says that when the filing meets the guidelines and the laws that apply, a permit is issued in one to two days in most cases. Those are the county's two wordings of the fast-track clock. They are not a single blended number, and they are not the deck office's separate timing notes.
On a standard residential building application, the county says the first set of review comments typically takes four weeks. The county sets that four-week figure next to a fast-track figure of generally one to two days. Use the clock that matches the project. Do not treat the fast-track figure as the review time for every residential filing.
Which small projects the county names
The county's eligible-project examples include a single-level deck and a shed under 200 square feet, and the county's sentence does not stop at that pair. Eligibility still has to match the guidelines. A house on a private well or a private septic system cannot use this track.
What stays on ordinary review
The county's limitation list keeps several scopes off the fast track:
- an interior alteration that includes a load-bearing wall
- a basement alteration that includes a kitchen
- an addition
- a screened porch
- a two-level deck
An addition in Ashton is one of those excluded scopes. The Ashton addition filing is on Ashton additions. A screened porch in Olney is also outside the fast-track list, and that porch scope is on Olney outdoor living.
A single-level deck can be eligible when the other limits are met. Deck rules for these two communities are on Ashton decks and Olney decks. Fence, shed, and gazebo scopes stay on Ashton outdoor living and the Olney outdoor living page linked above. Olney additions is the ordinary-review path for an Olney addition.
Confirm the house before you rely on the shorter clock
Ashton is not an incorporated town, and Olney is not an incorporated town. Neither community is a reason to file at a municipal counter. The building office for a county parcel in either place is Montgomery County Department of Permitting Services. General permit questions use 240-777-0311. Ask the county whether the project and the water and sewer service fit the fast-track list before you treat one to two business days as the plan.
Area context for the two communities is on the Ashton service area and the Olney service area. Broader county permit context stays on the Montgomery County permit guide.
