Auxiliary Dwelling Units

Capital Builders designs and builds Accessory Dwelling Units (ADUs) as fully functional secondary homes located on the same lot as a primary residence. Thoughtfully planned and well-integrated, ADUs offer flexible living solutions while maintaining the overall character of the property.

The benefits of adding an ADU are wide-ranging. For some homeowners, it provides a source of rental income. For others, it creates a comfortable space for aging parents or extended family—close enough for support, while still offering privacy and independence.

In some cases, homeowners choose to live in the smaller dwelling themselves, using the primary home as a rental property to offset mortgage costs and property upkeep. This flexibility is one of the key advantages that makes ADUs an increasingly popular option.

Designed to Fit Your Property and Lifestyle

Every ADU we design is tailored to the specific property, zoning requirements, and long-term goals of the homeowner. Whether attached, detached, or converted from an existing structure, the design is approached with careful attention to both function and aesthetics.

We focus on:

• Efficient use of space without sacrificing comfort
• Seamless integration with the existing home and lot
• Maintaining the single-family feel of the property
• Compliance with local zoning and building regulations

Balancing Privacy, Function, and Neighborhood Character

An ADU should feel like a natural extension of the property—not an afterthought. We take care to ensure that each unit complements the architecture of the main home while respecting the surrounding neighborhood.

This includes thoughtful placement, appropriate scale, and design choices that maintain harmony across the lot.

Experience You Can Build On

With extensive experience designing and building ADUs throughout the region, Capital Builders understands the unique considerations involved—from permitting and site planning to construction and final finishes.

We guide you through the entire process, helping you make informed decisions that align with your goals, budget, and long-term plans for the property.
