We Provide
Home additions in Frederick, MD let you gain space without leaving the neighborhood you love. Samuel Construction Group is a local room addition contractor that designs and builds family room expansions, primary suites, second story additions, sunrooms, bump outs, in law suites and garage additions that match your existing house inside and out. We are licensed and insured (MHIC #134199) with more than 15 years of experience in Frederick County and Washington County.
A ground level addition is the simplest structure and works well for aging in place, but it needs yard space and must meet setbacks. A second story addition keeps your yard but needs the existing foundation and framing checked first. If you have an unfinished basement, finishing the basement is often the lowest cost way to add living space. We walk your property and give you a realistic budget for each option before you pay for plans.
An addition touches foundation, framing, roofing, siding, mechanicals and interior finishes, so planning matters. We review setbacks and zoning, coordinate drawings, and submit permits to Frederick County, the City of Frederick or Washington County. Our crew handles the foundation, framing, roofing and dry in, then ties the new space into your existing heating, cooling, plumbing and electrical with licensed trades.

How much does a home addition cost in Frederick, MD? Cost depends mostly on size, foundation type, roofline and finishes. A bump out costs far less than a two story addition with a bathroom. Our home addition cost guide for Maryland breaks down price per square foot, and we give every client a written estimate after a free site visit.
How long does a home addition take? Small bump outs can be done in a few weeks once permits are issued. Most room additions take three to six months from permit approval to final inspection, depending on size, weather and inspections.
Do I need a permit for an addition in Frederick County? Yes. Additions need a building permit from Frederick County, or from the City of Frederick for homes inside city limits, and must meet zoning setbacks. We prepare the drawings and handle the permit and inspections for you.
Will the addition match my house? Yes. We match rooflines, siding, windows and interior trim so the new space looks like it was always there.
How can I pay for a home addition? Most homeowners use a HELOC, a cash out refinance or a renovation mortgage. See our guide to home renovation loans in Maryland, including FHA 203(k).

Second floor additions are common in Frederick and Hagerstown, especially when your property building space is limited. A conventional design practice in building a second floor home addition is to begin by duplicating the first floor and eliminating non-essential areas. You won’t need a second kitchen upstairs, so at Samuel Construction Group, we can replace that area with extra living space. Additionally, copying the area of the first floor bathrooms ensures that the main utilities running to them are aligned between the floors.
