Expert Home Addition Contractors in Arlington, Virginia (2026)
Looking for an expert home addition contractor in Arlington? Here's what Arlington's permit process, lot sizes, and historic districts mean for your project.
Why Arlington additions are different
Arlington has some of the tightest lots in NOVA, strict setback rules in R-5 and R-6 zones, and several historic overlay districts (Maywood, Lyon Village, parts of Clarendon). An "expert" Arlington addition contractor needs to know all three.
Arlington permit reality
- Plan review: 4–8 weeks at the Arlington Permit Office
- Setbacks: 25' front / 8' side / 25' rear in most R-6 zones — bump-outs often need a variance
- Historic district: add the HALRB review cycle (monthly hearings)
We pre-file zoning determinations before drawings are finalized so variances run in parallel with structural design.
Typical Arlington addition pricing (2026)
| Addition type | Range | Timeline |
|---|---|---|
| Kitchen bump-out | $55K–$110K | 3–4 mo |
| Primary suite on existing footprint | $190K–$320K | 5–7 mo |
| Second-story pop-up | $280K–$520K | 7–10 mo |
What "expert" actually means in Arlington
- Class A Virginia license (required for any project over $120K)
- Direct working relationship with Arlington plan reviewers
- Experience with party-wall conditions in semi-detached and rowhouse stock
- In-house structural engineer partner — Arlington reviewers reject under-detailed packages fast
