- Home Offices: Create a dedicated and comfortable workspace for remote or hybrid work.
- Guest Suites: Add private accommodations for visiting family and friends.
- Rental Opportunities: Build an ADU that can provide potential rental income.

Types of Home Additions & ADUs
Describe the different ways homeowners can expand their properties:

- Attached Garages: Build or expand an attached garage to provide additional parking, storage, or functional space.
- Primary Suite Additions: Create a larger bedroom, bathroom, walk-in closet, or private retreat.
- Accessory Dwelling Units (ADUs): Build independent living spaces such as in-law suites, backyard cottages, or rental units, subject to applicable requirements.

Benefits of Building an ADU
- Potential Rental Income: Use the ADU as a long-term rental or other permitted residential use.

- Flexible Guest Space: Create a private area for visiting guests or changing household needs.
