A homeowner on West Irving Street spent months getting their renovation through Montgomery County's Historic Preservation Commission. The plan called for demolishing a side wing, a patio, and a gazebo, then rebuilding. The Commission reviewed it against the county's preservation guidelines and conditionally approved it. That should have been the hard part. It wasn't.
Shortly after the county signed off, the Chevy Chase Village Board of Managers denied the owner's request to remove a 14-inch black gum tree standing in the front yard. The whole plan went back to the drawing board. The owner returned with a redesign that shrank the footprint and kept the tree in place, according to Montgomery County Historic Preservation Commission staff records from earlier this year.
If you're buying, selling, or renovating in Chevy Chase, that sequence is the thing worth understanding before you fall for a house here. The historic district review most people brace for is rarely the obstacle. The Village's own tree rules, run by a completely separate local government, often are.
The Commission Almost Always Says Yes
Chevy Chase Village's historic district sits under Montgomery County Code Chapter 24A, and the guidelines that govern it lean permissive by design. Most alterations and additions are supposed to be approved as a matter of course. Work on the rear of a house, out of view from the street, gets a lenient review. Even new construction gets latitude if it doesn't damage the character of the surrounding block. Staff reports from this year on Grafton Street, Hesketh Street, and Kirke Street all follow the same pattern: modest revisions to porches, rooflines, and rear additions, approved with a couple of routine conditions attached.
That's the part a lot of buyers already know, or at least assume: old neighborhood, historic overlay, expect a permit process. What they don't expect is a second government with its own reasons to say no.
The Second Approval Nobody Mentions At The Open House
Chevy Chase Village is a municipality, not just a historic overlay. It has its own Board of Managers, its own building department, and its own tree ordinance that runs independently of the county's preservation review. Before the Village will issue a building permit inside the historic district, it wants the county's Historic Area Work Permit in hand first. But getting that county permit doesn't settle anything with the Village itself. If your project touches a tree the Village wants to protect, the Village can still say no, on grounds that have nothing to do with architecture or historic character.
That's what happened on West Irving Street. The county's preservation staff cared about massing, materials, and whether the addition would be visible from the sidewalk. The Village's Board of Managers cared about a specific tree. Two different governments, two different tests, and the second one arrived after the first one had already been cleared.
The Village also asks for a tree preservation plan from its own arborist, with protective fencing installed before construction starts, not after. Skip that step and you're not dealing with a historic preservation violation. You're dealing with a Village stop-work order.
Chevy Chase Runs On Five Governments, Not One
The other detail that trips people up is the assumption that "Chevy Chase, MD" is one place with one process. It isn't. Montgomery County's own tax and permitting maps identify Chevy Chase Village, the Town of Chevy Chase, North Chevy Chase, Chevy Chase View, and Friendship Heights as separate municipalities inside the same general area, each with its own council layered on top of county rules. A house two blocks away can answer to a different government entirely.
| Municipality | What actually triggers extra review | Who decides |
|---|---|---|
| Chevy Chase Village | Any exterior work inside the historic district needs a county HAWP first; tree work needs a separate Village tree permit and arborist-approved protection plan | County Historic Preservation Commission, then the Village's own Board of Managers |
| Town of Chevy Chase | Adding roughly 700 square feet or more of impervious surface, a patio, a widened driveway, a large deck, triggers a Water Drainage Application | Town government |
| Chevy Chase View | Front yard driveway aprons and curb cuts need their own town-issued permit | Town government |
North Chevy Chase and Friendship Heights round out the list, two more names attached to the same stretch of the county, each running its own local government rather than deferring entirely to Montgomery County.
None of this shows up on a listing sheet. It shows up when a contractor pulls the wrong permit in the wrong order, which by most accounts costs a renovation four to six weeks it didn't need to lose. A contractor who has only worked one side of this map will often file for the wrong jurisdiction entirely, because from the street, the houses look like they belong to the same neighborhood. Legally, they don't.
What Changes When The Market Slows Down
For a stretch of the past few years, none of this mattered much to a buyer, because homes here were selling in under three weeks and there was no time to dig into permit history before writing an offer. That's shifted. As of mid-2026, homes in the Chevy Chase area were averaging 44 days on the market before going under contract.
That extra time changes what buyers actually look at. When a house is gone in under three weeks, nobody is pulling the Village's permit history or asking whether that new sunroom got a Historic Area Work Permit before it got a contractor's invoice. At 44 days, buyers and their agents have time to ask. Unpermitted additions inside a historic district don't just create cosmetic risk. They can complicate title, financing, and resale, because the next buyer's lender or insurer may ask the same questions you didn't get around to.
If you're selling a house here that's had work done in the last decade, it's worth confirming the paper trail exists before a buyer's inspector finds a rear addition that never went through the Village at all.
If You're Comparing This Side Of Western Avenue
Some buyers cross-shopping Chevy Chase are also looking at the DC side, just across Western Avenue, where a different tax structure applies at the closing table. Maryland layers a state transfer tax, a Montgomery County transfer tax, and a recordation tax that climbs with price, moving from about 0.89 percent on the first $500,000 up to 2.27 percent above $1 million under the county's current schedule. DC uses its own bracket system: 1.1 percent on sales under $400,000, stepping up to 1.45 percent at or above that threshold.
Which side of the line ends up carrying more of that cost depends on how the contract allocates it, and Maryland and DC don't share identical customs for who pays what. That's worth confirming in writing with your title company rather than assuming, especially if you're comparing a house in the Village to one a few blocks away in DC.
A Few Questions Worth Asking Before You Write An Offer
Does this specific address sit in the Village, the Town, or one of the neighboring municipalities? The boundary lines aren't always obvious from the street. Confirm it before you budget for renovation timelines, since the permitting sequence and approving bodies differ by jurisdiction.
If the house is in the historic district, has any exterior work been done recently, and did it get a Historic Area Work Permit? County HAWP records are public. It's worth checking before you close, not after.
Are there mature trees on the lot that a future project might need to remove? In the Village, that question can matter as much as anything the historic commission reviews. A tree the Board of Managers wants to protect can outweigh a design the county has already approved.
Chevy Chase rewards buyers who understand it's not one market with one rulebook. It's a small cluster of towns that happen to share a name, each running its own approval process, and the historic overlay that gets all the attention is often the easier of the two hurdles to clear.
