Inspection coverage in Arlington County

Arlington County sits between high-rise redevelopment corridors and older, lower-density neighborhoods, all within a single, densely built urban county. Housing includes high-rise condominiums near the Metro corridors and older homes in lower-density neighborhoods. This page indexes the inspection and testing services we run across those neighborhoods, from radon and mold testing to full home inspections.

What we see in Arlington County homes

Arlington County's housing stock splits between high-rise condominiums and apartments in redevelopment corridors like Rosslyn, Crystal City, Pentagon City, Ballston-Virginia Square and Clarendon-Courthouse, and older, established single family neighborhoods such as Lyon Village and Ashton Heights, with more affordable housing along Columbia Pike and a smaller, village-like core in Shirlington.

For a high-rise unit in Rosslyn, Crystal City, Pentagon City, Ballston-Virginia Square or Clarendon-Courthouse, an inspection focuses on the unit interior. Structure, roof and common systems belong to the building and its condo association, not the unit. For an older house in Lyon Village, Ashton Heights or along Columbia Pike, the inspection covers the full structure: roof age, foundation, grading, electrical service and any additions, since these homes are older and may have been altered or added onto over time.

High-rise units and building systems

In Rosslyn, Crystal City, Pentagon City, Ballston-Virginia Square and Clarendon-Courthouse, most of what we inspect is inside the unit. The building envelope, roof, elevators and shared mechanical systems are the condo association's responsibility, so we focus on plumbing, outlets, appliances and any visible water staining.

Additions and permit history

We check whether additions, finished basements and electrical upgrades were permitted and built to the standard they should have been.

Grading and water movement

Lots in the county's established neighborhoods were graded when the homes were built, and downspouts, driveways and additions since then can change how water moves. We look at grading, gutters and foundation walls for signs that water is heading toward the house instead of away from it.

Arlington runs its own permits and building inspections.

A permit history search through the county is a reasonable step before or after an inspection, especially on a house with visible additions or a finished basement that was not part of the original build.

Permit rules change, so confirm with Arlington County before you rely on this.

Arlington County inspections, answered straight

Does NextDay Inspect cover all of Arlington County, including high-rise areas like Rosslyn and Crystal City?

Yes. We inspect throughout Arlington County, from the high-rise corridors in Rosslyn, Crystal City, Pentagon City, Ballston-Virginia Square and Clarendon-Courthouse to the older, lower-density neighborhoods such as Lyon Village, Ashton Heights and Columbia Pike. Whether the property is a condo unit in a high-rise or a detached house on a residential street, we run the same radon, mold, air quality and home inspection services.

Is radon a bigger concern in a high-rise condo or an older Arlington house?

Radon comes from the ground, so risk is highest at or below grade. A garden-level condo or a house with a finished basement in an older neighborhood has more radon exposure to consider than an upper-floor unit in a high-rise. We test at the lowest livable level of the property, which is where radon testing tells you the most.

What should I expect from a mold inspection in an Arlington basement or crawlspace?

We look for moisture sources first: grading that slopes toward the house, downspouts that discharge too close to the foundation, and any sump pump or crawlspace vapor barrier that is missing or failing. Then we check for visible growth and elevated moisture readings on framing and finished surfaces. Finished basements are worth a closer look regardless of the home's age.

Do older homes in neighborhoods like Lyon Village or Ashton Heights need extra attention during an inspection?

Yes. Homes in these established neighborhoods are older and may have had additions, updated electrical service or renovated basements over time. We check whether that work was done to current standards, along with the age and condition of the roof, the electrical panel and the plumbing, since those systems are the ones most likely to have been touched or aged out since the house was built.
