Benefits of Building an ADU
There are several practical reasons homeowners choose to add an ADU to their property:
- Affordable cost: An ADU is built on existing property, eliminating the need to purchase additional land.
- Passive income: ADUs can be rented out on a short- or long-term basis, generating additional monthly income without the burden of a separate mortgage.
- Extended family housing: Many homeowners use ADUs to accommodate in-laws, adult children, or other relatives, providing privacy while keeping family close.
- Extra living space: An ADU can serve as a home office, studio, or workshop for the homeowner's personal use.
- Flexibility: ADUs can be customized to suit a range of needs, from a guesthouse to a rental unit or in-law suite.
Building an ADU also has the potential to increase overall property value, making it a practical long-term investment for many homeowners.
Types of ADUs Built Environment Inc. Offers
Built Environment Inc. specializes in several types of accessory dwelling units, each suited to different property layouts and homeowner goals.
Detached ADU: A stand-alone structure separate from the main home, a detached ADU can be added to single-family or multi-family properties. In California, detached ADUs can be up to 1,200 square feet, depending on available lot space. This type works well as a rental unit or detached office space, as it offers clear separation from the primary residence.
Attached ADU: An attached ADU shares a wall with the main home and is typically built onto the back or side of the house. In most areas of California, an attached ADU cannot exceed half the square footage of the primary home. A separate entrance is required if the unit is to be used as a rental.
Internal ADU: Constructed within the existing structure of the home — often in an attic or basement — an internal ADU shares utilities with the main house. This option can be a cost-effective way to add living space without expanding the building's footprint.
JADU (Junior Accessory Dwelling Unit): JADUs are smaller units capped at 500 square feet. They typically include a bedroom, bathroom, living area, and small kitchenette. JADUs require less permitting than full-sized ADUs, making them a more accessible option for many homeowners. In Placer County, streamlined permitting processes have made JADUs increasingly popular. Homeowners can choose from pre-approved designs or work with the Built Environment Inc. team on a custom layout.
Garage Conversion ADU: Converting an existing garage into a living unit is one of the faster and more cost-effective ADU options. The converted space can function as a rental apartment or as housing for a family member, without requiring new construction from the ground up.
When it comes to design, Built Environment Inc. offers modern ADU aesthetics that incorporate natural light, open floor plans, and clean lines. Their designers work with earthy tones — such as olive greens, browns, and turquoise — and often pair sleek finishes with wood elements to create cohesive, functional spaces that complement the main home.
The ADU building process at Built Environment Inc. follows a structured approach: an initial consultation and property evaluation, information gathering and site visit, followed by design development, 3D renderings, architectural plans, and permit acquisition. This process is applied consistently across all projects to support timely and thorough delivery.
