ADU Builders Lake Oswego
At JRW Construction, we specialize in building Accessory Dwelling Units (ADUs) in Lake Oswego, offering a flexible and efficient way to add value and livable space to your property. Whether you’re looking to create a rental unit, a guest house, a home office, or a private space for extended family, an ADU is the perfect solution without the need for a major home addition or relocation. Our team handles every step of the project—from design to final inspection—with care and precision.
We offer both detached and attached ADU construction in Lake Oswego, as well as garage conversions and basement build-outs. Each project begins with a consultation to understand your goals, the layout of your property, and the zoning requirements in your area. We work closely with you to develop a design that complements your main residence while meeting all local codes and regulations, ensuring the process runs smoothly and efficiently.

Building an ADU in Lake Oswego involves more than just putting up walls—it requires thoughtful planning around plumbing, electrical systems, HVAC, and efficient space usage. At JRW Construction, we coordinate all trades, manage permits, inspections, and scheduling to make the process seamless. Whether you’re starting from scratch or converting an existing structure, we ensure that the work is done correctly from the outset.
We focus on functionality and comfort in every ADU we build in Lake Oswego. We prioritize smart layouts, high-quality materials, and durable finishes that make the space comfortable, low-maintenance, and energy-efficient. From full kitchens and bathrooms to custom storage and energy-efficient systems, we tailor every unit to meet the needs of homeowners and future occupants.
As experienced ADU builders in Lake Oswego, JRW Construction provides a streamlined, full-service approach to every project. We’re here to help you create a high-quality, code-compliant living space that suits your needs—whether it’s extra income, more room for guests, or a peaceful place to work. If you’re considering building an ADU in Lake Oswego, we’re ready to bring your vision to life.
