Full-Service Home Additions
Everything Your Addition or ADU Needs
One contractor manages design, permits, foundation, framing, and finishing. You don't coordinate separate trades.
Design & Site Planning
We assess your lot, check setback and zoning requirements, and design an addition or ADU that fits your property and your county's rules before we ever submit a permit.
Foundation & Framing
Footings, foundation, and structural framing built to Maryland code. We handle the engineering coordination for load-bearing connections to your existing home.
Windows, Roofing & Siding
We match rooflines, siding, and window styles to your existing home so the addition looks original, not bolted on.
Electrical & HVAC
New circuits, panel upgrades if needed, and HVAC extension or mini-split installs so your addition is comfortable year round.
Plumbing & Bathrooms
Full bathroom or kitchenette plumbing for in-law suites and ADUs, including rough-in, fixtures, and venting done to code.
Drywall, Flooring & Paint
Full interior finish work matched to your home's existing trim, flooring, and paint scheme.
Separate Entrances
For ADUs and in-law suites, we build private exterior entrances that meet Maryland's separate-access requirements for legal occupancy.
Site Work & Grading
Excavation, grading, and stormwater management for detached additions and backyard ADUs. We handle tree removal coordination when needed.
Zoning, Permits & Inspections
We handle zoning review, site plan submission, permit applications, and every required inspection across Baltimore, Howard, Anne Arundel, and Carroll County.
What We Build
What's the Right Addition for Your Home?
Every property and every family is different. Here are the most common additions and ADUs we build across Maryland.
Master Suite Addition
A bedroom, full bathroom, and walk-in closet added to your existing footprint. The most requested addition in Baltimore County and Howard County right now.
Second-Story Addition
Build up instead of out when your lot doesn't have room to expand. Adds bedrooms and square footage without touching your yard.
In-Law Suite / ADU
A private bedroom, bathroom, kitchenette, and separate entrance, attached or detached. Built for aging parents, adult kids, or rental income.
Garage Conversion
Turn an existing garage into living space. Lower cost than new construction since the foundation and roof are already in place.
Sunroom / Family Room
A bright, multi-use addition off the back of your home. Popular as a connector between the kitchen and the backyard.
Detached Backyard Cottage
A fully separate structure on your lot, built as a standalone ADU. The highest-cost option but the most private and flexible.
Plan your project
Make the right choices for your home
An addition should solve a specific space problem while working with the rest of the home. Tell us whether you need another bedroom, a larger gathering space, more privacy for family or an easier-to-use layout. The property and existing structure shape what is practical.
Compare ways to gain space
A room addition, second-story addition, garage conversion and interior reconfiguration involve different work. Compare the usable space, disruption and connection to the existing home.
Review the property and structure
Available land, access, utilities and structural conditions need review. Zoning and permit requirements depend on the address and proposed use; approval should not be assumed.
Plan for the person using the space
For an in-law suite, discuss privacy, bathroom access, steps, storage and how the space connects to shared areas. A separate dwelling or rental use requires its own local feasibility review.
Our Process
How Your Addition or ADU Project Works
Additions involve more planning and permitting than a single-room remodel. Here's how we keep it organized.
01
Share your priorities
Tell us about the space, your town, the changes you want and your preferred timing. Bring photos or inspiration if you have them.
02
Review the proposed scope
Discuss layout, materials and existing conditions. Review what is included, any allowances and how extra work would be approved.
03
Agree the working plan
Confirm the project contact, expected schedule, access arrangements and any rooms or utilities that may be unavailable.
04
Build and review the result
Review the completed work together, note any remaining items and keep the written labor-warranty terms with your project records.

View All Projects →Budget and scope
What affects your home additions & in-law suites budget?
A useful estimate connects the price to the work being proposed. These are the main decisions to discuss for your home.
Structure and exterior
Foundations, roofing and connections to the existing building affect scope.
Utilities and use
Bathrooms, kitchens and separate living arrangements add coordination.
Approvals and access
Design, local review, site access and property constraints influence the plan.
Compare the same scope
Ask what is included, which selections or allowances are still open, who is responsible for approvals and how additional work would be agreed. Keep room in your planning for unexpected conditions discovered after demolition.
Financing is available subject to lender approval and terms. Your estimate request is free and does not commit you to a construction contract.

"We had just recently used Magic Hands Remodeling for a second project in our home. They worked tirelessly to fix post mold damages that were left over by other contractors. Communication was smooth and work started promptly. Company is very easy to work with and timeline and expectations were outlined in a very short amount of time. This company will not disappoint. Highly recommend!"

Your questions
Home Additions & In-Law Suites questions
Plan your next step with answers about scope, timing and the estimate process.
The cost depends on the agreed scope, material selections, existing conditions and any design or approval work. Request a free estimate for your home rather than relying on a general online price range.
Discuss your preferred timing at the consultation. The scope, material availability, approvals and existing conditions affect the schedule. Confirm the expected work sequence and any periods without access to rooms or utilities before work begins.
Not necessarily. A space for a family member and a legally recognized accessory dwelling can be treated differently. Confirm the proposed use and local requirements for your address before proceeding.
It may be an option. The existing structure, floor level, insulation, utilities, parking requirements and intended use all need review before choosing a conversion.
We are based in Reisterstown and serve Baltimore City and Baltimore, Howard, Anne Arundel, Carroll and Montgomery counties. Send your town or ZIP code so we can confirm availability for your project.
Financing is available subject to lender approval and terms. Our remodeling work includes a one-year written labor warranty; ask for its terms and exclusions with your proposal.
