Design an ADU around everyday life

A successful small home makes daily routines comfortable. Plan the entrance, kitchen, bathroom, laundry and storage around the future occupant.

Family, privacy and independence

  • For an aging parent, discuss step-free daily routes, reachable storage, bathroom maneuvering and future support needs with the designer and occupant.
  • For an adult child, consider a separate entrance, visitors, workspace, quiet hours and the balance between shared and private outdoor space.
  • For guests or a future renter, consider where luggage, cleaning supplies, coats and household equipment will live. Avoid treating storage as leftover space.

Make compact rooms work harder

  • Test furniture placement before fixing wall locations: bed access, dining chairs, sofa depth and a workspace all need usable clearances.
  • Plan kitchen landing space, appliance-door swings and a practical route between cooking, refrigeration and washing.
  • Consider where laundry noise, bathroom exhaust and mechanical equipment will be heard. Ask about sound isolation at shared walls and floors.

Design an entrance that feels like a home

  • Create a clearly identifiable arrival point, lighting, weather protection and a place for deliveries.
  • Look at window placement from both homes. Privacy can be improved with layout and landscaping as well as curtains.
  • Compare durable, maintainable finishes and explain the intended use to your partner. Rental assumptions and family needs may lead to different priorities.

Save a personal design brief

  • List must-haves, nice-to-haves and things you would trade for a lower cost. Ask the future occupant to review it.
  • Save a preferred architectural direction and bring photos of your existing home. The sketches on this site are inspiration; detailed accessibility and building compliance require professional design.

Turn the checklist into a project plan

Record each open question, the person responsible, evidence needed and target date. Confirm requirements with the city and your licensed design/build professionals.
