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'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.
Home Additions and ADUs in Maryland, Built Right and Permitted Properly
Most homeowners weighing an addition against moving come to the same conclusion: moving costs more in closing fees, a new mortgage rate, and the hassle of leaving a neighborhood they like. An addition or ADU lets you stay put and get the space you actually need. Magic Hands Remodeling, LLC is a licensed Maryland home addition contractor (MHIC #117279) based in Reisterstown, working across Baltimore County, Howard County, Anne Arundel County, and Carroll County.
Additions and ADUs in Baltimore County & Howard County
We get the most addition and ADU calls from homeowners in Reisterstown, Owings Mills, Towson, and Ellicott City dealing with one of two problems: a growing family that's outgrown the house, or aging parents who need their own space without moving into assisted living. Both situations point toward the same solution, and we've built it dozens of times in your neighborhood.
Maryland's New ADU Law
Legislation taking effect in late 2025 requires every Maryland county to allow at least one ADU by right in most single-family zones. That's a real shift. Counties that used to make ADU approval discretionary now have to allow it under standard zoning, which means faster approvals in counties that were previously slow. We track these changes by county so you don't have to.
How Much Does a Home Addition or ADU Cost in Maryland?
A standard room addition runs $100 to $300 per square foot, putting a 500 square foot addition at $50,000 to $150,000. A garage conversion ADU runs $80,000 to $120,000. An attached ADU sharing a wall with the main home runs $100,000 to $160,000. A detached backyard cottage runs $150,000 to $250,000 or more. We give you an exact written number after walking your property.

Additions involve more planning and permitting than a single-room remodel. Here's how we keep it organized.
Free Site Assessment
We walk your property, check zoning and setback requirements, and talk through what you actually need the space to do. No charge, no pressure.
Design & Proposal
We design a layout that fits your lot and your county's rules, then give you a written proposal with line-item pricing before any permits get filed.
Permitted Build
We submit for zoning and building permits, break ground once approved, and send daily photo updates through foundation, framing, and finishing.
Final Walkthrough
We walk the finished space with you and pass final occupancy inspection before calling the job done. Your 1-year written warranty starts on sign-off day.
