As housing costs continue to rise and urban areas become more crowded, homeowners are looking for smart ways to add functional living space. Accessory Dwelling Units (ADUs) have become one of the most effective housing solutions in 2025. At BERG, we specialize in designing and building ADUs that match your needs and add long-term value to your property. In this guide, we explain what ADUs are, why they matter, and how they can work for you.

What is an accessory dwelling unit (ADU)?

An Accessory Dwelling Unit (ADU) is a small, fully functional residential space built on the same lot as a main home. ADUs offer key features like a kitchen, bathroom, bedroom, and living area. They’re a smart choice for homeowners who want to use their property more efficiently. ADUs generally fall into three categories:

• Detached Units: Separate buildings on the property, such as guest houses or converted garages.
• Attached Units: Units built as additions to the main home, with their own private entrances.
• Interior Conversions: Finished spaces within the home, like basements or attics, redesigned for independent living.

Why build an ADU in 2025?

ADUs address many common residential needs. Here are some reasons more homeowners are choosing them this year:

1. Expand living space

In areas where housing supply is limited, ADUs provide extra living space without requiring a second property or a full-scale remodel. Cities are making it easier to get approval, and more zoning rules now support ADU development.

2. Support family needs

An ADU can offer a safe and private space for aging parents, adult children, or extended family. It allows for close connection while maintaining independence and privacy.

3. Generate rental income

A well-located ADU can provide steady income through long-term or short-term rentals. This can help cover mortgage payments and increase financial flexibility.

4. Create a private workspace

Remote work is here to stay. ADUs are ideal for home offices, studios, or hobby spaces, offering a quiet place to focus just steps away from your main home.

5. Add property value

An ADU can raise your property’s market value. More buyers are looking for homes that include flexible living options, and an ADU is a feature that stands out.

What to consider before building an ADU

Planning your ADU project carefully is essential. Here are a few key points to keep in mind:

• Zoning and Regulations: Make sure your property meets local ADU zoning laws. Many cities have updated their rules to encourage ADU development.
• Utility Access: Your ADU will need proper connections to water, electricity, and sewer systems. These must meet building codes and safety standards.
• Design and Usability: A good design should match your main house and use space wisely. Choose a layout that supports comfort and convenience.
• Financing Options: Look into financing through home equity loans, ADU-specific programs, or personal lending options.
