Popular Home Addition Types

Here are some of the most requested additions from Southern Maryland homeowners:

Additional Bedrooms. We build these most often for growing families or for an adult child moving back home. We match the roofline and siding of your existing house so the addition looks like it's always been part of the home.

Expanded Living Rooms. If your family has outgrown your living room, we extend the footprint and rework how it connects to the rooms around it.

Home Offices. More homeowners want an office set apart from the noise of the house. We build these with sturdy walls, plenty of outlets, and enough natural light that you can comfortably go through your workday.

Sunrooms. Enjoy an outdoor living space year-round with a shaded sunroom. We make these additions with insulation and connect it to your HVAC system so can stay comfortable in every season.

In-Law Suites. We can build a bedroom, bathroom, and kitchenette for an aging parent or family member, with a separate entrance whenever the lot allows it.

Playrooms and Recreational Spaces. Have a room dedicated for family activities, whether that's a kids' playroom, a home gym, or a game room.

What a Home Addition Costs in Southern Maryland

This is what common home additions cost in this region:

General Home Addition

Home additions in Southern Maryland start around $500 per square foot, with the final number shaped by the type of addition and the finishes you choose.

Building Out vs. Building Up

Building out keeps you within your property's setback and lot coverage limits. Building up means reinforcing the existing floor and walls below to carry the new weight.

Plumbing and Electrical Work

A bedroom or living room addition is mostly framing and finish work. An in-law suite or kitchen extension means running new water and gas lines, which adds labor and material costs.

Front Entry and Porch Additions

A front entry addition or a porch addition typically starts around $25,000 for a mid-level build and $30,000 for a high-end one. This combined range comes from Villa's existing cost content and hasn't been verified separately for each project type, so it's worth confirming with the client before publishing.

Permits and Zoning for Home Additions in Southern Maryland

Charles, Calvert, and St. Mary's Counties each run their own permitting department, but all three enforce Maryland's adopted building code. Once you submit plans, the county checks them against setbacks and lot coverage before it reviews the construction. Additions and other structural work usually take several weeks to clear both stages.

Projects near the water or inside a designated Critical Area tend to hit the longest zoning review, since an extra layer of environmental review is required. If your property is subject to an HOA or recorded covenants, you may need separate approval in addition to what the county requires.

Villa Builders pulls your permit and prepares your application. We work directly with your county's permitting office during design and planning, so we clear zoning requirements before we break ground.

Home Additions FAQs

Will the new addition match the style of my existing home?expand_more
Yes. Our team focuses on ensuring that your addition seamlessly integrates with the architectural style, materials, and finishes of your existing home.
Do I need to obtain permits for a home addition?expand_more
Permits are typically required for home additions. We handle the entire permitting process, ensuring everything meets local building codes and regulations.
Can you add space to older homes?expand_more
Absolutely. We have extensive experience working on older homes, carefully blending new additions with existing structures while maintaining their character.
How will you take care of the house while you are working?expand_more
We set up dust and floor protection and ask that you take steps to protect and/or move your most treasured items from work areas. We are professionals. The care we take while working in and around your home is our top priority.
Are you good with pets?expand_more
Many of our clients have pets. Depending on the pet’s temperament, owners may crate or make other arrangements for them during construction. We are accustomed to helping to ensure that pets don’t get out but prefer not to be fully in charge of them.
Tell us about your communication and scheduling processesexpand_more
We formulate your schedule once we have a firm understanding of your project and as we head toward the end of our design and planning process. Once we start construction, communication is constant, with email, phone calls, and scheduled site meetings. We keep you in the know.
How do we handle customer change orders during the process?expand_more
Our planning and design process helps to mitigate the need for most change orders. It’s not uncommon for clients to request additional work and we are delighted to oblige. Items like additional painting can be priced and scheduled fairly quickly. Depending on the scope of work you want to add, will dictate the time needed to develop the cost and get the work scheduled for you.
Do you use subcontractors?expand_more
We prefer to work with our subcontractor trade partners since it allows us the flexibility to put the right crews on your job. Our subcontractors have been working with us on Villa projects for a long time and understand how we work. They thoroughly inspect the scope of work during our planning process, which helps us estimate the correct amount of time and cost up front, reducing the need for change orders mid-project.
