Custom Accessory Dwelling Units Built for Maryland Living
Add a detached guest house, rental suite, or in-law unit to your property—designed and built by a licensed Anne Arundel County contractor who handles every step from permits to punch list.
An accessory dwelling unit is one of the smartest investments a Maryland homeowner can make. Whether you need a private space for aging parents, a rental unit that generates monthly income, or a detached home office that actually feels separate from your house, a well-built ADU adds square footage and real value to your property. In Anne Arundel County—where housing demand stays strong year-round—a quality ADU can pay for itself faster than almost any other home improvement.
At Backyard Bobby's, we design and build ADUs from the ground up. We handle the full scope: architectural planning, county permits, excavation, foundation, framing, roofing, electrical, plumbing, and finish work. You get one licensed contractor managing the entire project instead of juggling five different subs. That means fewer delays, clearer communication, and a final product that actually matches what you were promised.
Maryland updated its ADU regulations to make it easier for homeowners to add these units, and Anne Arundel County has its own set of zoning requirements around setbacks, size limits, and utility connections. We stay current on every rule so your project sails through the permitting process without surprises. If you've been thinking about an ADU, a quick conversation with our team will tell you exactly what's possible on your lot.
Backyard Bobby's designs and builds accessory dwelling units as a single licensed contractor (MHIC #05-163777) — handling architectural planning, county permits, excavation, foundation, framing, roofing, mechanical systems, and finish work under one roof. Serving 19 Anne Arundel County communities. A well-designed ADU can generate $1,500–$2,500/month in rental income. Typical builds take 4–6 months from permit approval to move-in.

Why Choose Us for Accessory Dwelling Units
Turnkey Construction
One contractor from design through move-in day. We manage excavation, foundation, framing, mechanical systems, and interior finishes so you never have to coordinate multiple trades.
Rental Income Potential
Anne Arundel County's rental market is strong. A well-designed ADU can generate $1,500–$2,500 per month, often covering your mortgage payment or funding your next project.
Aging-in-Place Ready
We build ADUs with wide doorways, step-free entries, and accessible bathrooms so your family members can live independently—right in your backyard.
County Permit Expertise
We navigate Anne Arundel County's zoning codes, setback requirements, and utility connection rules. Your permits get filed correctly the first time, avoiding costly delays.
Property Value Boost
A finished ADU adds usable square footage to your property record. Homes with ADUs in the Annapolis and Severna Park areas consistently appraise higher than comparable properties without them.
Energy-Efficient Builds
Every ADU we construct uses modern insulation, efficient HVAC, and tight building envelopes. That means lower utility bills for you or your tenants—even during Maryland's humid summers.
Our Accessory Dwelling Units Process
Here's exactly how your accessory dwelling units project works from start to finish.
Consultation & Design
We visit your property, review your lot's zoning classification, and discuss how you plan to use the unit. You'll get a preliminary layout, a realistic budget range, and a clear picture of what Anne Arundel County will allow on your specific parcel.
Permits & Planning
We prepare construction drawings, handle the county permit application, coordinate with utility providers for water and sewer connections, and schedule any required inspections. You sign off on the final plan before any work begins.
Site Work & Foundation
Our crew handles excavation, grading, and drainage to prepare your lot. We pour the foundation—slab or crawlspace—to meet Maryland's structural and frost-depth requirements, setting a rock-solid base for the build.
Construction & Finish
Framing, roofing, siding, electrical, plumbing, HVAC, insulation, drywall, flooring, cabinetry, and fixtures all happen under our supervision. We schedule county inspections at every milestone and hand you the keys to a fully finished, move-in-ready unit.
