Licensed ADU Architects

Accessory dwelling units (ADUs) are becoming increasingly popular as they add value to your property. They provide affordable housing for family members or additional rental income for property owners. They are essentially secondary housing units that legally share the same property as the primary residence.

Our experienced ADU architects will work with you to design your ADU to meet your individual and building code requirements. EZ Plans is skilled at obtaining a permit for your ADU plans quickly and efficiently. Whether for single or multi-family residences, EZ Plans simplifies the process and keeps you updated throughout the project.
