21 March 2025

Step-by-step ADU guide: Learn how to plan, design, and build an accessory dwelling unit for rental income, extra space, or a backyard studio.

Accessory Dwelling Units (ADUs) are a smart way to expand your living space, create rental income, or build a cozy retreat on your property. Whether you're adding a backyard studio, a guest house, or a rental unit, here’s how to bring your ADU vision to life:

1. Site Analysis & Planning

Before breaking ground, assess your property’s layout, zoning regulations, and infrastructure. Consider access, privacy, and utility connections to ensure your ADU fits seamlessly into the space.

2. Design & Customization

From compact studios to multi-room units, ADUs can be tailored to your needs. Choose a design that complements your main home and aligns with your lifestyle—whether it’s a modern cabin retreat, a home office, or a rental unit.

3. Permits & Approvals

Navigating local building codes is essential. Check with your city or county to obtain the necessary permits for construction, utility hookups, and occupancy requirements. Some areas offer incentives for ADUs, so research available programs.

4. Construction & Site Preparation

Prepare the site by clearing space, setting foundations, and ensuring utilities are in place. Whether you're building from scratch or installing a prefabricated unit, proper site prep is key to a smooth construction process.

5. Final Touches & Move-In

Once construction is complete, focus on interior details—lighting, storage, and sustainable materials that enhance comfort and functionality. Whether it's a rental unit or a personal retreat, your ADU is now ready to serve its purpose!
