Flexible Guest & ADU Living Designed for Comfort
Adding an Accessory Dwelling Unit (ADU) or guest quarters is a smart way to expand your living space and increase property value. Most of our ADU projects range from $150,000 to $1 million, depending on size, layout, and level of customization. Design Build Remodeling Group of Maryland provides tailored solutions to create comfortable, fully functional living spaces for family or rental purposes. Pricing has been updated for 2026 to provide the most accurate and transparent guidance for homeowners. While every project is unique, this range reflects the cost of the majority of ADU additions we complete.
A free-standing “Guest House” is often referred to nowadays as an “ADU”, an acronym for Accessory Dwelling Unit.
There are some jurisdictions in Maryland that will allow an ADU to be constructed on your property as a totally separate, free-standing structure.
Other jurisdictions require that an ADU must be “attached” to the existing main dwelling in some manner.
In either case, we will work creatively with you to design the “ADU” as separate living quarters, for independent living by your family members or guests.
To find out what type of ADU is allowed in your local jurisdiction, call us today for your FREE FEASIBILITY STUDY*
