Accessory Dwelling Unit
A secondary housing unit located on the same property as a primary residence, featuring independent living facilities including a kitchen, bathroom, and sleeping area. ADUs can be attached to the main house, built as separate structures, or created by converting existing spaces like garages or basements.
Example
“Maria converted her detached garage into an accessory dwelling unit to rent out for extra income while keeping her main house for herself.”
Memory Tip
Think of it like a phone accessory - it's a useful add-on to your main device (house) that serves a similar but secondary function.
Why It Matters
ADUs can provide additional rental income for property owners while increasing housing supply in communities, but they must comply with local zoning laws and building codes.
Common Misconception
Not all areas allow ADUs - many municipalities have strict regulations or prohibitions that must be researched before construction or conversion.
In Practice
A homeowner converts their detached garage into a 600-square-foot ADU with a kitchenette and full bathroom, then rents it for $1,500 per month to help offset their mortgage payments.
Etymology
From Latin 'accessorius' meaning 'additional' or 'supplementary' - it's an additional dwelling that accessories or complements the main house.
