Whether you’re looking for an ADU builder near me, planning a detached ADU for your backyard, or seeking a trusted ADU contractor in Emerald Hills to handle the entire project from design to construction, our team is here to help you bring your vision to life.
When planning your new ADU, there are several important site preparation, design, and construction considerations we bear in mind.
Your accessory dwelling unit needs to fit in with the style and look of the surrounding property and neighborhood.
This depends on whether you plan to rent your ADU or use it as a family annex. If renting in Bay Area, some tenants may require certain levels of privacy
Before making any designs, we consider how you want to use your dwelling unit and ensure enough space. If it is too small, the unit could feel restrictive, while if it is too big, it may fall foul of Bay Area ADU construction laws.
Ensuring all units have an open route to the street for accessibility and safety reasons. If you have tenants, it’s important to consider more private access routes that bypass your main home area and other accessibility features such as wheelchair ramps and handrails.
Depending on your location, Bay Area ADU construction regulations and local zoning laws will guide us through the structural design of your unit.
We take site analysis and preparation seriously to get the right type of foundation and structural quality for your unit.
Our ADUs are more spacious by considering brilliant views, windows/doors, and outdoor spaces for better living.
Bump-out additions offer extra square footage without major construction. Ideal for expanding kitchens, bathrooms, or adding mudrooms in Bay Area homes. These micro-extensions are cost-effective and practical, giving you more living space without altering your home’s layout drastically.
Conventional additions expand your home with a single room, like a bedroom or bathroom. In the Bay Area, this ground-level solution fits your lifestyle needs and budget while enhancing comfort, space, and value without the complexity of multi-room additions.
Full additions are becoming popular in Bay Area because they are smaller houses attached to the main house. They have several rooms, including guest rooms, garages, bathrooms, and in-law suites, but they don’t have a kitchen. This type of addition involves plumbing, electrical, and HVAC installation.
When you can’t expand outward, go up. Second-story additions add valuable space without losing yard area. Ideal for relocating bedrooms upstairs while keeping common rooms below. Popular in Bay Area neighborhoods with limited lot space or tight zoning restrictions.
A kitchen addition increases space for appliances and gatherings. Bay Area homeowners can enhance flow and function with a bright, open kitchen design. Our team ensures great layout, natural light, and ventilation tailored to your style and space.
Bathroom additions improve comfort and home value. Whether a half-bath or luxury suite, they’re customized to your needs. In the Bay Area, we manage plumbing, layout, and finishes to create beautiful, functional bathrooms—even with limited available space.
Emerald Hills is known for its peaceful neighborhoods, spacious lots, and premium property values making it an ideal area for ADU development. With rising housing demands and more families seeking flexible living options, accessory dwelling units have become one of the smartest investments a homeowner can make.

Perfect for:
As your Bay Area ADU construction contractor, DevArt8 Builders will help you plan, design, and build any of the four main types of accessory dwelling units.
Only one ADU is allowed per primary dwelling. ADUs are allowed in single-family residential areas and on any lot with a permitted single-family home in a multi-family residential area.
Lots under 8,500 sq. ft. require ADUs of about 275 - 640 sq. ft. with a maximum of one bedroom. Lots over 8,500 sq. ft. can have ADUs up to 800 sq. ft. with a max of two bedrooms. ADUs converted from existing single-family homes can't be larger than 25% of the main structure.
ADUs must comply with the same setbacks as the main dwelling, except if above a detached garage. Detached ADUs must be located at least 10 feet from the main dwelling. When above a detached garage, ADUs must have a 5-foot setback from interior side yards, a 5-foot rear yard setback, and a 20-foot street side yard setback on corner lots.
Detached accessory units must be one-story and not exceed 12 feet in height unless a higher-pitch roof is required to match the main dwelling. When located above a detached garage, the height should not go beyond 30 feet.
Building an ADU is a major investment—and Devart8 Home Builders has refined a smooth, stress-free process that keeps you informed at every stage.
