A detached ADU is a standalone structure on your property, separate from the main house, offering independent living space. This option provides maximum privacy and design flexibility, creating a distinct new dwelling.

Choosing a contractor who understands the local context is crucial for any construction project in Gresham. Our team is frequently in Gresham, working on sites from the historic downtown area to the newer developments near Powell Butte, which gives us firsthand knowledge of common site conditions, soil types, and utility access challenges. This local familiarity helps us anticipate potential issues and plan more effectively, avoiding costly delays and ensuring a smoother build process for your ADU.
Our construction approach prioritizes structural integrity and energy efficiency. For instance, we often specify advanced framing techniques and high-performance insulation like closed-cell spray foam in our Gresham ADUs, achieving R-values significantly higher than code minimums. This attention to detail in the building envelope means lower utility bills for the occupant and a more comfortable living environment year-round. We also focus on proper drainage solutions, especially important with Gresham's rainfall, incorporating perimeter drains and appropriate grading to protect your investment.
When you work with us, you can expect a methodical process from initial site assessment to final walkthrough. We provide detailed project schedules and regular updates, outlining each phase of construction, from foundation pouring and framing to electrical rough-in and finish work. Our goal is to demystify the building process, providing clear explanations for material choices and construction methods, so you always understand the 'why' behind our work.
Gresham homeowners can typically build an ADU up to 900 square feet, or 75% of the primary dwelling's footprint, whichever is smaller, provided it meets other setback and lot coverage requirements. The city's zoning code, specifically Gresham Development Code (GDC) Chapter 2.110, outlines these parameters, which means careful design is needed to maximize usable space within these limits. We always verify the specific zoning district for your property, as some overlays or historic designations might introduce additional considerations. This upfront research ensures your proposed ADU design complies with all local regulations before plans are submitted for permitting.
ADU permit approval in Gresham typically takes 6-12 weeks from the time of a complete application submission, though this can vary based on the complexity of the project and the city's current review workload. The process involves reviews by planning, building, and sometimes public works departments, which means all plans must be meticulously prepared to avoid resubmissions. We handle the entire permitting process, from drafting detailed architectural plans to coordinating with city planners, ensuring all required documentation, like site plans, floor plans, and structural calculations, is accurate and complete on the first submission. This streamlines the approval timeline significantly.
Slab-on-grade foundations are very common for ADUs in Gresham due to their cost-effectiveness and efficiency, especially on relatively flat sites with stable soil conditions. However, we also frequently use crawl space foundations, particularly on sloped lots or when homeowners desire easier access for future utility maintenance, which provides a buffer against moisture and allows for better insulation. The choice depends heavily on site-specific factors like soil reports, drainage patterns, and the existing grade of your property, all of which we assess during our initial site evaluation to recommend the most appropriate and durable foundation system for your ADU.
