Expand Your Living Space with Custom Structures
At Gabriel Maggio Construction, we specialize in designing and building high-quality accessory structures that enhance your property's functionality, value, and appeal. Whether you need additional living space for family members, rental income opportunities, or simply more room for your lifestyle, our expert team delivers exceptional results.
Accessory Dwelling Units (ADUs)
ADUs are self-contained living spaces with their own entrance, kitchen, bathroom, and living area, located on the same property as a single-family home. These versatile structures can transform your property and lifestyle in numerous ways:
Types of ADUs We Build
- Detached ADUs – Stand-alone structures built separately from your main home
- Attached ADUs – Connected to the main house, often with a separate entrance
- Interior ADUs – Converted spaces within your existing home (basement, attic, etc.)
- Garage Conversions – Transforming existing garages into functional living spaces
Benefits of Building an ADU
- Generate Rental Income – Create a steady revenue stream from your property
- Multigenerational Living – Provide independent living space for aging parents or adult children
- Home Office or Studio – Create the perfect dedicated workspace
- Guest Accommodations – Offer visitors privacy and comfort
- Increase Property Value – Add significant value to your real estate investment
