Decks & Porches in McLean, Virginia
McLean's established neighborhoods — from walkable Salona Village near Old Dominion Drive to the wooded, sloping lots toward the river in Langley Forest and Chesterbrook — call for a deck or porch built around the real site, not a stock plan. We design and build custom composite decks, covered porches, and screened additions, sequenced around Fairfax County's permit process and the HOA architectural review most McLean communities require.
The Short Answer
A new deck or covered porch in McLean typically runs $20,000–$60,000, reflecting the larger lots, sloped terrain, and higher-end finishes common across the area. McLean falls under Fairfax County's permit process — any deck or porch structure more than 16.5″ above grade needs a building permit, with plan review typically running 3–5 weeks. Most established McLean communities also carry HOA architectural review, and many lots slope toward the Potomac under mature tree canopy that has to be engineered around with elevated footings and terracing — we handle all of it and deliver a written, line-item quote within 24–48 hours.

Local Knowledge
What Building in McLean Actually Involves
- Permits & TimingAny deck or porch structure more than 16.5″ above grade needs a Fairfax County building permit; plan review typically runs 3–5 weeks. We tell you exactly which applies to your project before we start.
- HOA Architectural ReviewEstablished communities like Salona Village, Broyhill Estates, and The Reserve carry HOA covenants requiring separate architectural approval on deck materials, railings, and porch additions — we run this alongside the county permit, not after it.
- Sloped, Tree-Canopied LotsMany McLean lots, especially toward the Potomac in Langley Forest and Chesterbrook, slope down toward the river under mature oak and tulip poplar canopy — decks need elevated, engineered footings and multi-level framing instead of a flat-lot build.
- Lot Size & Location VarietyMcLean runs from the walkable, village-scale lots around Salona Village and Old Dominion Drive (ZIP 22101) to larger wooded parcels on the Tysons-facing side of town (ZIP 22102) — every deck or porch design starts with the real elevation of the site.

What Neighbors Say
Trusted on Backyards Like Yours
“Our lot near Langley Forest drops almost six feet from the house to the back fence — the multi-level deck they engineered steps right down with it instead of forcing a retaining wall to fight the slope.”
“HOA approval for our covered porch in Salona Village came back with zero revision requests, and the same crew that measured our house built it.”
“They framed the deck around two mature oaks we wouldn't let anyone touch and it still came out exactly the size we wanted.”

Decks & Porches FAQs
Does Lawn Theory handle permits and HOA approval for deck and porch builds in McLean?
Yes. McLean falls under Fairfax County's building permit process, and established communities — including Salona Village, Broyhill Estates, and The Reserve — carry HOA covenants requiring separate architectural approval. We handle both the county permit and the HOA submission as part of your project.
My lot slopes toward the Potomac — can a deck still work on that kind of grade?
Yes. Grade changes toward the river are common in McLean, especially in Langley Forest and Chesterbrook. We use elevated framing, engineered footings, and stepped multi-level decks to work with the slope instead of leveling the whole yard to force a flat plan.
What's the difference between a composite deck and a covered porch, and which is right for a McLean home?
A composite deck is an open, low-maintenance platform built with engineered decking boards over a structural frame; a covered porch adds a roof structure tied into the house, which usually means additional framing, flashing, and sometimes a permit review for the roofline itself. Most McLean homeowners choose based on how much of the season they want to use the space and whether they want it visually matched to the home's existing roof and trim.
How does Lawn Theory work around mature trees when building a deck or porch in McLean?
Root-aware footing placement, hand-digging near trunks, and framing that clears major root systems instead of cutting through them. Much of McLean's tree canopy predates the homes, and protecting it is usually a condition of both the county permit and the HOA review.
Do you build screened porches, or only open decks?
Both. Screened porches are a common request in McLean for the humid months, and we frame them with the same structural rigor as an open deck, just with screen panels, a roof, and often a ceiling fan circuit added to the electrical plan.
What size decks does Lawn Theory build in McLean?
McLean's lots vary widely, from the tighter, walkable parcels around Salona Village and Franklin Park to the larger wooded properties toward the Potomac in Langley Forest and The Reserve. Design starts with the actual dimensions and grade of the specific lot rather than a one-size template, so a compact deck off a village-scale home gets sized differently than a multi-level deck on a sloped, wooded lot.
Does a deck or porch always require a permit in McLean?
Almost always, yes. Fairfax County generally requires a building permit for any deck or porch structure more than 16.5 inches above grade, which covers nearly every attached deck or porch. Grading, excavation, or tree removal near the Potomac bluffs can trigger a separate land-disturbance review, which we flag during the walkthrough so it's never a surprise on your quote.
