FAQs

About ADUs

What is an ADU, and how it is used?2025-12-17T09:58:37-08:00

An ADU (Accessory Dwelling Unit) is a self-contained residential unit built on the same lot as a single-family home. ADUs can be attached to the main house, converted from an existing space (like a garage), or built as a detached structure in the backyard. They’re commonly used as rental units, in-law suites, guest houses, or independent living spaces for family members. Asher Brothers Construction designs and builds custom ADUs that align with your property, goals, and local building codes.

What are the benefits of building an ADU (Accessory Dwelling Unit)?2025-12-17T09:58:40-08:00

Building an ADU (Accessory Dwelling Unit) or backyard home offers several valuable benefits. It can generate rental income, increase your property’s value, and create a flexible living space for guests, aging parents, or adult children. ADUs can also serve as private home offices or studios. At Asher Brothers Construction, we specialize in designing and building custom ADUs that enhance your property’s functionality and long-term value.

Do I need a permit to build an ADU on my property?2025-12-17T09:58:44-08:00

Yes, constructing an ADU (Accessory Dwelling Unit) requires obtaining the appropriate permits from your local city or county. These permits confirm compliance with zoning laws, building codes, and other municipal regulations. At Asher Brothers Construction, we manage the entire permitting process on your behalf, including paperwork, approvals, and inspections, so your ADU project moves forward smoothly.

Can I customize the design of my ADU to fit my needs and property?2025-12-17T09:58:48-08:00

Absolutely! At Asher Brothers Construction, we specialize in custom ADU design and construction, tailoring every detail to match your lifestyle, preferences, and property layout. From open-concept floor plans and smart storage solutions to high-quality finishes and energy-efficient systems, we will work closely with you to create a space that’s both functional and beautifully personalized.

Can I rent out my ADU once it is built, and what are the rules?2025-12-17T09:58:51-08:00

Yes, ADUs (Accessory Dwelling Units) can be a valuable source of rental income. Homeowners often use them as long-term rentals or short-term vacation units, depending on local regulations. Rental laws vary by city and county, so it’s important to understand your area’s zoning rules, occupancy limits, and permitting requirements. Asher Brothers Construction will help you navigate the local regulations and design your ADU to meet all necessary legal and functional standards for rental use.
