Outdoor Living Design & Build in Fairfax County, Virginia

From McLean estates to Reston town centers, Fairfax County is our home base — and our largest, most varied service area. We design and build patios, kitchens, fire features, and lighting as one plan, sequenced around the county's permit and HOA review process.

The Short Answer

Outdoor living projects in Fairfax County start at $18,000. Most decks and covered patios require a Fairfax County building permit (ground-level wood patios generally don't), plan review usually runs 3–6 weeks, and land-disturbance review may apply if grading or tree removal is involved. Many Fairfax subdivisions also require separate HOA architectural approval — we handle both tracks and deliver a written, line-item quote within 24–48 hours.

Local Knowledge

What Building in Fairfax County Actually Involves

  • Permits & TimingMost decks and any structure over 16.5″ above grade need a Fairfax County building permit; plan review typically runs 3–6 weeks. Ground-level wood patios usually don't require one — we tell you exactly which applies to your project.
  • HOA Architectural ReviewMany Fairfax subdivisions carry deed restrictions requiring separate HOA approval on materials, railings, and screening — we run this alongside the county permit, not after it.
  • Land DisturbanceGrading, excavation, or tree removal can trigger a land-disturbance review even for a ground-level patio — we flag this during the walkthrough, not after your quote.
  • Lot VarietyFrom McLean and Great Falls estate lots to Reston and Tysons townhome-style properties, Fairfax County covers the widest range of lot sizes we build on — every design starts with your actual property, not a template.

Fairfax County, Answered

Outdoor Living Design & Build FAQs

Do I need a permit for a patio or deck in Fairfax County?

Most decks and any structure over 16.5 inches above grade need a Fairfax County building permit; plan review typically runs 3–6 weeks. Ground-level wood patios generally don't require one. We confirm exactly what applies to your project during the walkthrough.

How much does outdoor living design & build cost in Fairfax County?

Most complete projects start at $18,000 — final price depends on scope — a single feature like a patio or fire pit starts lower, while a full backyard renovation with a kitchen and multiple hardscape features runs higher. Every quote is written and line-item.

Do Fairfax County HOAs require separate approval?

Many do. HOA architectural review covers materials, colors, railings, and screening, and runs separately from the county building permit — both are often required at the same time. We manage both tracks so your project doesn't stall waiting on paperwork.

What triggers a land-disturbance review?

Grading, excavation, or tree removal can trigger a Fairfax County land-disturbance review, even for a ground-level patio project. We flag this during your walkthrough so it's reflected in your quote and timeline up front, not discovered mid-project.

Which Fairfax County areas do you serve?

All of them — McLean, Great Falls, Vienna, Oakton, Tysons, Reston, Herndon, Burke, Springfield, Centreville, Chantilly, Annandale, Falls Church, Fairfax City, and every neighborhood in between. Each has its own dedicated page above.

How long does a Fairfax County outdoor living project take?

Design and permit lead time typically runs 4–8 weeks given Fairfax's review process. Once approved, most single-feature builds take 1–3 weeks; full backyard renovations take longer depending on scope and HOA requirements.

Do you work on both large estate lots and smaller townhome lots?

Yes. Fairfax County has the widest range of lot sizes we build on — from McLean and Great Falls estates to compact Reston and Tysons townhome lots — and every design starts with your actual property, not a one-size template.
