Smart Additions and ADUs for Growing Needs
At J. Leahy Construction, we specialize in home additions and ADU (Accessory Dwelling Unit) construction that blends seamlessly with your existing home while adding the space and functionality you need. Whether you’re building a detached ADU for rental income or guest space, adding a new bedroom or bathroom, or creating a home office or expanded living area, our team brings thoughtful design and skilled execution to every project. We manage the entire process in-house—from excavation and site preparation to framing, finish work, and final inspection—ensuring quality control, efficient timelines, and clear communication from start to finish. With years of experience building in the Portland Metro area and a deep understanding of local codes, zoning requirements, and environmental conditions, we create additions and ADUs that are as durable and practical as they are beautiful. We also offer guidance through the design and permitting stages, helping you navigate every step of the process with confidence. Every structure we build is tailored to meet your lifestyle, maximize your property’s potential, and enhance the long-term value and livability of your home.
