More home,
without moving.
A custom ADU adds a private, beautifully built living space to your property — for family, guests, rental income, or room to grow. Byrd designs and builds it end to end.
A second home on the land you already love.
An accessory dwelling unit is a fully independent living space — kitchen, bath, and private entrance — on the same lot as your main house.
Homeowners call them in-law suites, backyard cottages, guest houses, or carriage apartments. Whatever you call yours, we build it with the same craftsmanship and finish level as any Byrd renovation — and handle the zoning, permits, and construction so you don't have to.
Choose the ADU that fits your property.
Every lot is different. During your consultation we'll recommend the approach that makes the most of your space, budget, and goals.
Detached Cottage
A freestanding home in your backyard — full kitchen and bath, private and self-contained.
Modern Backyard ADU
A contemporary standalone studio or one-bedroom, designed for privacy, light, and clean lines.
Garage Conversion
Turn an underused garage into finished, comfortable living space without expanding your footprint.
Basement Suite
Transform a lower level into a private apartment with its own entrance, light, and full amenities.
One space, many futures.

A dignified, comfortable home for aging parents or grown kids — close by, but with their own front door.

ADU basics, answered.
Are ADUs allowed where I live?
It depends on your county and municipality — rules on ADUs vary across Maryland and continue to evolve. We review the zoning and permitting requirements for your specific address as the first step of your consultation, so you'll know what's possible before you commit to anything.
How much does an ADU cost?
Cost depends on the type of unit, its size, site conditions, and the finishes you choose. Rather than quote a misleading number, we scope your project in detail and provide a clear, itemized estimate before any work begins.
How long does it take to build?
Most ADUs run several months from design through construction, with permitting timelines varying by jurisdiction. We give you a realistic schedule up front and keep you updated at every phase.
Can I rent out my ADU?
Many homeowners do. We design and build to code so your unit can be properly permitted and, where local regulations allow, legally rented — protecting both your investment and your peace of mind.
