What is an

Accessory Dwelling Unit?

Accessory dwelling units, or ADUs, are small, self-contained living spaces that are built on the same property as a single-family home. ADUs are also known as granny flats, in-law units, or secondary suites. They are becoming increasingly popular as a way to add affordable housing to neighborhoods and provide a source of income for homeowners.

Some ADUs are detached from the main living space, such as a separate guesthouse or carriage house. Others are attached ADU models, such as a basement apartment or a garage conversion. ADUs provide you with more space for your family, build the value of your primary house, and generate extra income through rentals.

Why

Build

an ADU?

Increase the Property Value

Property owners can increase the value of their homes by building an ADU. Your new ADU will increase the value of your property. You can also rent it out for extra income.

Extend Your Living Space

Not enough space in your main house? If your primary residence is already maxed out, you can extend your living space and use your ADU as an extension home, guest house, or storage area.

Accommodate Aging Parents

Create a home for your elderly parents, children or other family members.

Three

Innovative

Factors

Structurally Insulated Panels

Structurally Insulated Panels

SIPs are made up of insulating foam cores sandwiched tightly between two structural facings that are designed and precisely manufactured off-site. Once these are completed, it only takes 30-60 days of onsite work and one contractor to complete your ADU.

Helical Piles Foundation

Helical Piles Foundation

A helical pile is a steel shaft with helices that is screwed into the ground to help anchor the ADU to the soil. This process requires only small machinery and a team of 2-3 people to complete in about 3 days.

Pre-engineered Plan Sets

Pre-engineered Plan Sets

Pre-engineered plan sets are ready-to-build diagrams which allows for quick, reliable & simple construction process – streamlining the need for inventorying materials or planning.
