What sets us apart is that we manage everything under one roof. You’re not juggling multiple contractors or navigating the permitting maze alone. We coordinate with city officials, utility companies, and inspectors so your project stays on schedule and within scope. Our designs balance functionality with the realities of your site and Gig Harbor’s building standards.
Whether you’re looking to house family members, generate rental income, or simply make better use of your property, an ADU can deliver real value. We’ll walk you through what’s possible on your lot and what the actual timeline and costs look like.
Building an ADU in Gig Harbor WA requires balancing three competing pressures: keeping costs reasonable, ensuring the structure lasts through the Pacific Northwest climate, and delivering results on schedule. Our approach addresses all three without compromise. We source materials built to handle coastal weather and heavy use, then structure the project timeline to avoid unnecessary delays while maintaining craftsmanship. Whether you’re adding a backyard cottage, converting a garage, or finishing a basement unit, the payoff depends on smart construction. Every project meets local code requirements and is designed with rental income, aging-in-place needs, or future resale value in mind. That’s not just compliance – it’s the difference between a liability and an asset.
Detached ADUs are small, independent units built separately from the main home and are also called “backyard cottages”. Have an underused backyard space? You can make it useful through long-term rentals or multigenerational living with the help of detached ADUs. Call us for site planning, custom design, permitting, and full build.
Attached ADUs share at least one wall or structural component with the main home. We also call them home extensions or garage ADUs, as they are usually built over garages or as side additions. Need a space for in-law suites or flexible rental space with shared utilities? This option is for you that adds luxury and comfort to your lifestyle.
Conversion ADUs are garage or basement conversions. We use existing square footage, like basements, attics, or garages, and transform them into livable units. This option is best for fast turnaround and lower cost-per-square-foot, making it ideal for short-term rental or guest suites.
