Bright accessible bedroom with wide doorway in an ADU built for a parent

Why families choose this

She does not want a facility. You do not want her forty minutes away. An ADU on your lot gives your parent her own front door, her own kitchen, and her own schedule — with family twenty steps away instead of a phone call away. Many families weigh this against the cost of assisted living or a retirement community — and for a lot of them, one build beats years of monthly bills.

Attached or detached — which fits your parent?

An in-law suite attached to your house means no yard to cross at night. Mom walks through one connected home, not across a dark lawn, and help is one wall away. A detached cottage gives the most privacy: her own building, her own porch, her own quiet. The county treats the two types a little differently — our attached ADU guide explains the setback and entry rules for space joined to the house — but both follow the same permit path: a county ADU permit first, then building permits.

Designed for safety, not just comfort

A parent's ADU is designed around the hard parts of aging. Start with a no-step entry, so there is never a stair to fall on. Add a walk-in shower with grab bars and a bench. Make doorways wide enough for a walker. Put bright lighting in every room. Our aging-in-place ADU page has the full safety checklist. Build these in from day one — adding them later costs far more.

Privacy for both generations

Closeness only works with a door that closes. A good parent ADU has its own entrance, sound insulation in any shared wall, and its own thermostat — so she sets her temperature, you set yours, and nobody hears the 6 a.m. news through the drywall. Together for dinner; apart for everything else.

When she no longer needs it

This is the question families are shy about asking, so we will answer it: the ADU does not go to waste. A properly permitted unit becomes a long-term rental, a guest space, or a home office. Build it legal now — with the county ADU permit — and it keeps working for the family for decades. More questions? See the main ADU FAQ.

If your neighborhood has an HOA, bring the CC&Rs to the first visit — the county's staff position is "HOA guidelines apply," so the HOA's architectural rules still matter. Get their approval in writing early.

Questions homeowners ask us

Attached or detached — which is better for a parent?

Attached wins on safety — no yard to cross at night, and help is one wall away. Detached wins on privacy — her own building, her own quiet. For a parent with mobility trouble, attached is usually the kinder choice. We will walk your lot and show you both.

What safety features matter most?

A no-step entry, a walk-in shower with grab bars and a bench, doorways wide enough for a walker, bright lighting, and everything daily on one floor. Build these in from day one — adding them later costs far more.

What if they need a wheelchair someday?

Then you will be glad you built for it now: a flush no-step threshold, doorways wide enough for a wheelchair, a roll-in shower, and turning space in the bathroom and kitchen. Tell us at the design stage and we plan for the wheelchair, not just the walker.

How do we keep everyone's privacy?

Three things: a truly separate entrance, sound insulation in any shared wall, and separate heating and cooling so nobody fights over the thermostat. Designed right, both generations forget the other is there — until dinner.

What does a parent-focused ADU cost?

It depends on the type. A converted garage or basement falls in the conversion range — Foster Remodeling publishes $50K–$200K for conversion-type projects in Northern Virginia. A new attached addition or detached cottage costs more — Makara ADU quotes $150K–$350K per The Banner. 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.
