For many Maryland homeowners, the thought of moving to get more space just isn’t appealing especially when you already love your neighborhood, your school district, or your home’s charm.
That’s where a home addition comes in. Whether you need a new bedroom, expanded kitchen, or even a custom garage, adding onto your existing home can be a smart and satisfying investment.
But one of the first questions people ask is: How much does a home addition in Maryland cost?
The answer depends on several factors including the type of addition, the materials you choose, the complexity of the project, and the local labor market.
Let’s walk through the key considerations that affect the price and why so many Maryland homeowners trust Certified Home Remodelers to get the job done right.
What’s the Average Cost of a Home Addition in Maryland?
Generally speaking, home additions in Maryland can range anywhere from $150 to $400 per square foot, depending on the scope of work and finishes.
For a standard 400-square-foot room addition, that could mean anywhere from $60,000 to $160,000 or more.
It’s a big range but that’s because every home addition is unique. Costs will vary depending on things like:
- Foundation work: Is the addition being built on a new slab, crawlspace, or basement?
- Plumbing and electrical: Are you adding a bathroom or kitchen that requires extensive utility connections?
- Second-story construction: Multi-level additions involve more structural engineering and materials.
- High-end finishes: Wood flooring, custom cabinetry, and stone countertops can add up quickly.
Types of Additions and Their Typical Costs
To give you a clearer picture, here are some common home additions in Maryland and their typical investment range:
- Primary Bedroom Suite Addition: $80,000–$150,000
Often includes a walk-in closet and en-suite bathroom. - Kitchen Expansion: $70,000–$120,000
Includes cabinetry, countertops, plumbing, and appliances. - Family Room or Sunroom Addition: $60,000–$110,000
Great for extra entertaining space or natural light. - Garage Addition (Attached or Detached): $50,000–$90,000
A functional way to add storage, workspace, or even a future bonus room above.
The most cost-effective way to get a real number? Schedule a consultation with a local contractor who knows Maryland building codes, zoning requirements, and seasonal pricing fluctuations.

What Influences the Cost of Home Additions?
There’s more to the cost than just square footage. Here’s what really drives the price:
1. Permit and Code Requirements
Maryland counties and cities (like Westminster and Frederick) each have their own permitting process and inspection guidelines. Your contractor should handle all permits and ensure everything is up to code.
2. Design & Architecture
If you’re looking for a cohesive addition that blends with your existing structure, professional design is a must. From sunrooms to second stories, Certified Home Remodelers offers design-build services to help you go from idea to execution.
3. Utility Relocation
Sometimes, HVAC systems, plumbing, or electrical panels need to be upgraded or moved to accommodate the addition. This can add to your project’s cost, but it also improves the value and functionality of your home.
4. Material Choices
Higher-end siding, roofing, flooring, and fixtures will affect your final cost but also your satisfaction with the finished product. A reputable contractor will help you balance budget and quality to find the right fit for your lifestyle.
Is a Home Addition Worth the Investment?
Absolutely. A well-designed addition adds square footage, functionality, and resale value to your home—all without the hassle of relocating. Plus, you can finally have the space you need to:
- Host guests comfortably
- Create a private home office or studio
- Give kids their own rooms
- Expand your kitchen or living area
- Add storage with a custom garage
And if you’re located in Carroll County, Frederick County, or the greater Baltimore area, you’ve probably noticed how competitive the housing market has become. A custom addition gives you a major advantage when it’s time to sell and, even more importantly, improves your day-to-day life while you’re living there.
