If you're planning to tear down a house in McLean that was built before 1985, the first form in the permit file matters more than the floor plan. Fairfax County's own asbestos certification form tells applicants the inspection is required for all buildings built before 1985, full stop. But the Virginia statute underneath that form tells a more complicated story: single-family homes are generally exempt from mandatory pre-demolition asbestos inspection, unless the renovation or demolition is being done for commercial or public development purposes. Two different documents, two different answers, and the gap between them can decide whether your teardown moves in weeks or months.
That gap matters more in McLean than almost anywhere else in Northern Virginia, because so much of what gets sold here isn't really a house. It's a bid on the dirt.
The Lot Without a House Already Has a Price
Near the corner of Lewinsville Road and Lancia Drive, a 25-acre estate that belonged to the Jewett family for more than 60 years is becoming Knolewood, a 24-lot subdivision on what local real estate reporting has called the last remaining contiguous undeveloped parcel in McLean. FFXnow reported that the site plan was submitted to Fairfax County in December 2023, county staff finished their review in September 2025, and the existing structures on the land were cleared to make way for two cul-de-sacs and wide, tree-lined streets. Homeowners will build with one of three approved firms, Artisan Builders, Galileo Signature, or Winthrop Builders, on lots ranging from 0.82 to 1.2 acres.
Here's the part that matters if you're shopping for anything else in McLean right now. As of spring 2026, individual Knolewood lots have hit the market with no house on them at all, and they're pricing at $2.45 million to $2.5 million for roughly 0.83 acres. That's not a renovation estimate or a builder's projection. It's a live asking price for raw ground.
Once you know that number, an older McLean listing reads differently. A pre-1970 colonial on a comparable lot, priced anywhere near or below that land-value line, isn't being marketed as a house you'll update. It's being marketed as a parcel with a structure standing on it that will likely come down. Fairfax County's 2022 demographics report puts roughly 30 percent of homes in the McLean planning district at pre-1970 construction, with another 17 percent built in the 1970s. That's a large share of what's actually for sale sitting inside the exact age range where the land, not the living space, is doing the pricing.
The Fork Nobody Explains at the Listing Appointment
This is where the permit question stops being paperwork and starts being a cost and timeline decision.
Virginia Code Section 36-99.7 sets the baseline rule for the whole state: a local building department can't issue a permit to renovate or demolish a building with an original permit issued before January 1, 1985, until it receives certification that the structure has been inspected for asbestos. But the same section carves out single-family dwellings from that requirement, unless the work is being done for commercial or public development purposes.
What the statute doesn't spell out is how that carve-out applies to the most common teardown scenario in McLean today: a builder who buys an older single-family house specifically to demolish it and construct a new one for resale. Is that a private single-family project, or is it commercial development because the intent from day one was never to live in the house that's coming down? The law doesn't answer that question directly, and Fairfax County's own permit paperwork doesn't resolve it either. The county's asbestos certification form simply states the requirement applies to all pre-1985 buildings, without walking through the single-family exemption at all.
In practice, that means the honest answer is: it depends on how your specific project gets classified when it's reviewed, not on a default rule you can assume applies. If you're buying a McLean house to live in and might renovate or eventually rebuild yourself, ask Fairfax County's Land Development Services directly which category your permit falls into before you budget your timeline. If you're a builder or investor planning a demolition for resale, plan for the full inspection path rather than hoping the single-family exemption will apply, because the county's practical stance on builder-driven teardowns isn't written down anywhere you can point to in advance.
What the Full Path Actually Costs
Fairfax County's Land Development Services handles residential demolition through its DEMOR permit process in the PLUS online system. Before that permit is issued, the county requires a plumbing permit for any sewer cap-off, written utility disconnection confirmations from providers like Dominion Energy, Washington Gas, and Fairfax Water, and, if asbestos is present, a separate miscellaneous permit for the abatement itself. None of that is optional paperwork. It's sequenced, and each step has to clear before the next one starts.
Here's roughly how the two paths compare in practice, based on Fairfax County's published permit requirements and current pricing published by McLean Demolition, a Class A DPOR-licensed contractor that has worked teardown-rebuild projects throughout the Georgetown Pike corridor since 2012:
| Step | Typical Cost | Who Needs It |
|---|---|---|
| Asbestos inspection | $300 to $600 | Required before permit issuance if the structure predates 1985 and doesn't qualify for the single-family exemption |
| Asbestos abatement (if ACM is found) | Varies by scope | Licensed abatement contractor, coordinated before mechanical demolition begins |
| Utility disconnection confirmations | No direct fee, but adds lead time | Every project, regardless of asbestos status |
| Full house demolition | $9,400 to $19,800 | Every project, once permits clear |
The dollar range on demolition itself is the same either way. What changes is the sequence before it. A project that clears the single-family exemption can move from permit application to demolition in a matter of weeks. A project that needs an asbestos inspection, and possibly abatement if materials like the 9-by-9-inch floor tile common in 1950s and 1960s construction turn up, adds inspection scheduling, lab turnaround, and a second permit review before the demolition permit issues at all.
Why the Median Price Doesn't Answer This Question
McLean's own submarkets make a single median almost useless here. As of spring 2026, Zillow's zip-code data showed 22101, the core estate district, running well over $1.6 million in typical home value, while 22102, which blends Tysons-adjacent condos with older single-family stock, sat closer to $840,000. That's roughly a two-to-one spread inside one community name, and it exists because the two zip codes are selling fundamentally different products, not because one side of McLean is simply cheaper.
The Washington Post's reporting on sales in McLean's Franklin area captured the same pattern at the individual sale level, with prices ranging from a $1.08 million teardown to a new build of almost 10,000 square feet selling for nearly $5 million, and a separate new-construction estate listed at $9.85 million in August 2025. A single median price sitting somewhere in between describes none of those transactions accurately. It just averages them.
What This Means If You're Comparing a McLean Listing
- If the house predates 1970 and sits on a lot near or above 0.75 acres in neighborhoods like Chesterbrook, Salona Village, or McLean Hamlet, compare the asking price to nearby raw-lot pricing, not to renovated comps in the same neighborhood.
- If your plan is to live in the house as-is or handle a light renovation yourself, ask the listing agent whether an asbestos certification is already on file. That single document can be the difference between a fast permit and a stalled one.
- If your plan is to demolish and rebuild for resale, budget and schedule for the full inspection-and-abatement path rather than assuming the single-family exemption applies to your project.
- Start the utility disconnection letters from Dominion Energy, Washington Gas, and Fairfax Water as early as possible. That step has to clear before the demolition permit issues, regardless of asbestos status.
A Short FAQ
Does every house in McLean built before 1985 need an asbestos inspection before it can be torn down? Not automatically. Virginia law exempts single-family dwellings from that requirement unless the demolition is for commercial or public development purposes. Fairfax County's own paperwork doesn't spell out how that exemption applies to builder-driven teardown-rebuild projects, so it's worth confirming directly with the county before assuming either way.
Why would empty land in a new subdivision cost more than some existing houses with land attached? Because the existing houses being compared often sit on smaller or less desirable lots, or because their price already reflects an expected demolition. Knolewood's lots are priced on scarcity, being some of the last significant undeveloped acreage in McLean, which puts them at the high end of what raw ground commands here right now.
Is the 22101 versus 22102 zip code split reliable for comparing value? It's a useful starting signal, not a final answer. The two zip codes contain different housing mixes, so a lower median in 22102 reflects more condos and smaller lots pulling the number down, not a uniformly less valuable area.
