An ADU (Accessory Dwelling Unit) is a smaller, independent residential unit located on the same lot as a single-family home. It includes its own kitchen, bathroom, sleeping area, and a separate entrance. Common types include:

• Detached: A separate building (like a backyard cottage or tiny house)
• Attached: Built onto the main home as an extension
• Interior: Converted space within the home (e.g., basement or attic)

Why Would You Want an ADU?

1. Extra Income

ADUs can be rented out to long-term tenants or as short-term rentals like Airbnb, providing homeowners with a steady stream of passive income.

2. Multigenerational Living

They’re ideal for families who want to live close but independently—perfect for aging parents or adult children.

3. Increased Property Value

Homes with ADUs often have higher resale value and greater buyer interest due to added living space and versatility.

4. Flexible Living Space

Use it as a guest house, home office, art studio, or even a downsized retirement space while renting the main home.

5. Environmentally Friendly

ADUs help with urban infill—maximizing the use of land in existing neighborhoods without expanding into undeveloped areas.

6. Aging in Place

Older homeowners can maintain independence while staying close to family, avoiding the costs of assisted living facilities.

What to Consider Before Building an ADU

• Zoning Laws: Local codes may limit the size, type, and location of ADUs.
• Permits: You’ll likely need permits for construction, plumbing, and electrical work.
• Utilities: Some municipalities require separate meters or connections.
• Cost: Construction can range from $50,000 to $300,000+ depending on scope and quality.
• Parking: Requirements vary—some cities waive extra parking near public transit.

Is an ADU Right for You?

If you’re looking to generate income, support family living arrangements, or future-proof your property, building an ADU can be a smart and flexible investment.
