The hiring advantage
Great caregivers are hard to find — and harder to keep. A private suite on your lot turns a good job into a great living situation. For a nanny, it means no commute and a real home. For an elder-care aide, it means being minutes away when Mom needs help at 2 a.m. A private suite is the benefit that sets your offer apart from every family offering just a paycheck.
What caregivers need
After hours, a caregiver is off duty — and the suite has to respect that. The must-haves: a separate entrance so they are not walking through your living room at 10 p.m., a real kitchen so they can cook their own meals, and laundry access. Privacy is not a perk here; it is what makes the arrangement last.
Nanny vs. elder-care aide
The space is similar; the priorities differ. A nanny's suite centers on the kids' schedule — sound separation matters when toddlers nap and the nanny does not. An elder-care aide's suite centers on access — close to the parent's space, with the safety features of an aging-in-place design. Tell us who the suite is for and we design around their day, not a template.
When the arrangement ends
Caregivers move on — kids grow up, parents' needs change. The suite does not go to waste: it becomes a guest space, a long-term rental, or — when the next parent needs it — an in-law suite. Build it as a legal ADU now and it keeps working for decades. (For the family side of this, see ADUs for aging parents.)

What it costs
A caregiver suite costs like any small ADU. Conversion-type projects fall in Foster Remodeling's published $50K–$200K range (Northern Virginia); new detached builds fall in Makara ADU's quoted $150K–$350K range (per The Banner). The right number for your lot comes from the free walk and the written estimate — not from this page.
A note on prices: material costs move up and down, and no two lots need the same work. Treat any numbers on this page as starting points, not quotes. Your written estimate after our free lot walk is the real number for your project.
