ADU DESIGN AND BUILD

Designing for an ADU is complex.  Small decisions can significantly affect your property and how you experience it. If you’re thinking about creating an ADU, hiring a design/build team that is experienced with such spaces and that you trust is key.

An ADU can offer you many benefits, including maximizing your lot space or creating extended space for family members or guests. It may provide flexible-use space that serves as a guest room one moment and a rental unit at another.

ADUs also make ideal multi-generational living arrangements, especially for aging adults or older children who want to be close and maintain independence at the same time. Adding legal square footage to your house can also increase your property value.

WHAT IS AN ADU—ACCESSORY DWELLING UNIT?

ADUs can come in many forms: a new build, standalone structure, an addition built onto your home, or a converted basement, garage, attic or outbuilding.

Portland city codes require that ADUs meet certain criteria for sleeping, cooking and sanitation. Our design/build team brings a high level of expertise plus the experience to develop ADU plans that meet your needs while they satisfy strict codes.

Working with you we maximize your ADU usage in the space available and optimize insulation and ventilation for comfortable living and efficient cooling and heating. We make sure that there is adequate headroom, especially in basements and attics. We ensure that windows and exterior doors provide ample ventilation and natural daylight and provide both visual and auditory privacy, while meeting egress requirements.

LIVING SPACE CONVERSION: DESIGN YOUR DREAM ADU

ADUs can come in many forms: a conversion of an existing garage or outbuilding, an extension built onto your home, or a converted basement or attic.

During the design phase, it’s important to consider size restrictions for your lot, how to maximize space usage in a small footprint, weather efficiency and sound dampening, utilities for the space, accessibility concerns, storage, the use of natural lighting, and the necessary level of privacy.

With Portland ADUs, builders are required to meet certain criteria for sleeping, cooking, and sanitation.

Our skilled team is highly experienced in designing to meet all code requirements. We ensure proper fire separation, and make sure that stairs either meet current code–based on tread size and ceiling height clearance–or qualify to be grandfathered in. All systems that we install are ADU code compliant.
