Finished one-bedroom apartment — a private space for a grown child

A launchpad, not a basement couch

They are saving for their own place — or figuring out what is next. An ADU gives your grown kid a real front door, a real kitchen, and real privacy — and the rent, if you charge any, stays in the family instead of going to a landlord. It is the difference between "living at home" and having a home.

Which type fits best

A garage conversion is usually the most affordable route: the structure already exists. A basement apartment works well in houses with a walkout or good ceiling height. And a small backyard cottage gives the most independence — its own building, its own yard. We will walk your house and show you which one fits your lot and your budget.

Privacy saves the relationship

The families that make this work all do the same three things: a separate entrance so nobody walks through anyone's living room, real sound separation, and clear expectations set before move-in. A 24-year-old with a private door and a kitchen is a neighbor you love. A 24-year-old crashing in your living room is a countdown.

When they move out

They will — that is the point. And the ADU keeps paying: it becomes a rental unit for a long-term tenant, a guest space, or a home office. Build it as a legal ADU now, with the county ADU permit, and the launchpad keeps working the day they launch.

Sources: Chapter 197 of the 2025 Laws of Maryland (HB 1466/SB 891) — no long-term rental ban in the statute; Charles County Bill 2026-06 / ZTA 25-189 (published draft, Art. XXVI §297-430.E).

The money talk

We build houses, not family financial plans — so we will not tell you what to charge. But have the conversation before construction, not after: rent or no rent, guests and overnight guests, shared utilities, and a timeline. The ADU works great. The family meeting is what makes it work.

Questions homeowners ask us

Is it weird to build a home for my kid?

Not anymore. Multigenerational living is one of the most common reasons families build ADUs. A private unit with its own door is not spoiling them — it is giving them a real home while they save, study, or start a career.

Garage, basement, or cottage — which fits?

Garage conversions usually cost the least. Basements work well with a walkout and good ceiling height. A small detached cottage costs more but gives total independence. Your house and lot decide — we will show you the options at the free walk.

What happens when they move out?

The ADU keeps working: rent it to a long-term tenant, use it for guests, or turn it into a home office. That is why building it as a legal, permitted ADU matters — permitted space has a future.

Should we charge rent?

That is a family decision, not a construction decision — we will not advise you on it. Some families charge enough to cover the added utilities, some charge nothing, and some treat it as a launchpad fund. Decide before you build, put it in writing, and revisit it yearly.

Can it become a home office later?

Absolutely — that is the beauty of a permitted ADU. When your kid launches, the same space becomes a backyard office, a guest suite, or a rental. Build flexible space once; use it three ways over twenty years. Our home office ADU page covers the office side.
