What I see as a home inspector

Stephen P. Sinnott

Chief Inspector

Montgomery County contains everything from older postwar housing to luxury renovations and major new construction.

Expensive finishes should never substitute for evaluating the underlying building. Older electrical systems, sewer lines, drainage, additions and decades of remodeling deserve attention, while new homes should still be inspected for installation and workmanship defects.

What I look at closely in Montgomery

  • Sewer lines
  • Drainage
  • Additions
  • Decades of remodeling
  • New-build workmanship
Required before settlement

Radon testing is required for most Montgomery County home sales.

With limited statutory exceptions, a single-family detached home or townhome must be tested for radon before the sale is completed. Montgomery County is classified as an EPA Zone 1 area, the highest predicted potential for elevated indoor radon.

Radon Testing in Montgomery County
  • Test performed less than one year before settlement, using a County-approved device
  • The seller performs the test or gives the buyer the opportunity to
  • Both buyer and seller must receive the results
  • Generally excluded: condominium and cooperative units, and homes in Barnesville, Kensington and Poolesville

Confirm current requirements with your agent or the county before settlement.

New construction in Montgomery

A smaller new-home market

Montgomery County continues to produce new housing despite being heavily developed. Future supply increasingly depends on redevelopment, infill, townhomes, condominiums and multifamily housing rather than traditional large subdivisions.

Market commentary

The state of the Montgomery market

A home inspector’s perspective, by Stephen P. Sinnott.

A market driven by Washington and much more

Bethesda, Rockville, Silver Spring, Gaithersburg, Germantown, Potomac and the county's many other communities vary considerably, but all benefit from proximity to Washington.

Federal government, biotech and healthcare

The county is home to major federal institutions including NIH, FDA and NIST and has a nationally important biotechnology and life-sciences sector. Major private employers and federal contractors add to an employment base that extends directly into Washington, D.C.

Schools and housing costs

Montgomery County Public Schools are an important draw, and school assignments can strongly influence buyer interest. The challenge is cost. High prices, taxes and financing costs mean buyers increasingly evaluate not only location but the condition and future maintenance expense of the home.

My outlook

The county's access to Washington, federal employment, biotechnology, healthcare and highly regarded communities gives it unusually strong fundamentals. Affordability may restrain portions of the market, but demand for well-located housing should remain substantial.

Real estate markets change, but the fundamentals of a community usually change much more slowly. My approach is to look beyond a monthly sales number and consider why people want to live in the area, what supports employment and what buyers are actually purchasing when they walk through the front door.
