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.
A garage conversion transforms an existing garage structure into a fully functional, habitable living space, often including plumbing, electrical, and insulation upgrades. This process unlocks significant property value and provides flexible living options without expanding your home's footprint.
We manage the entire ADU permitting process in Portland, from initial application submission to final permit issuance. This ensures your project complies with all local zoning and building codes, avoiding costly delays.
ADU Design involves creating detailed architectural plans, structural drawings, and material specifications for your Accessory Dwelling Unit. This comprehensive design package ensures your ADU is code-compliant, functional, and aesthetically integrated with your existing property.
ADU engineering provides the structural and civil calculations needed for your Accessory Dwelling Unit's foundation, framing, and utility connections. This ensures your ADU is built safely, to code, and withstands Portland's specific environmental conditions.
Choosing Mighty ADU Company for your Tigard ADU project means partnering with builders who know the local context. We're not just building structures; we're integrating them into existing properties and neighborhoods, understanding Tigard's specific permitting processes and design review considerations, especially for properties within the Tigard Triangle or near the Fanno Creek Trail. This local insight allows us to anticipate challenges and streamline the construction timeline, because we've already done the groundwork on what Tigard requires.
Our construction approach prioritizes durability and energy efficiency. For instance, we often specify advanced framing techniques to reduce thermal bridging and use high-performance insulation like closed-cell spray foam, which provides a superior R-value and air sealing. We also pay close attention to site-specific conditions, such as soil types common in Tigard, ensuring appropriate foundation systems are engineered, whether it's a slab-on-grade or a crawl space, because a solid foundation is non-negotiable for longevity.
When you work with us, expect a structured process from initial site assessment to final occupancy. We begin with a detailed feasibility study, confirming your property's ADU potential against Tigard's zoning code, including lot coverage and setback requirements. Throughout construction, we maintain rigorous quality control, conducting regular inspections and providing clear updates on progress and upcoming milestones. Our goal is a finished ADU that enhances your property and provides a valuable, lasting asset.
Typical setback requirements for an ADU in Tigard generally mirror the primary dwelling's setbacks, often requiring 10 feet from the rear property line and 5 feet from side property lines. However, these can vary based on your specific zoning district (e.g., R-1, R-7, R-10) and whether the ADU is attached or detached, which means a thorough review of your property's zoning map and the Tigard Development Code is essential. We always perform a detailed site analysis to confirm exact requirements for your parcel before design begins, because misinterpreting setbacks can lead to costly redesigns or permitting delays. Corner lots or properties adjacent to public open spaces might have additional considerations.
The permitting process for an ADU in Tigard, from initial application to permit issuance, typically takes 3 to 6 months, assuming all plans are complete and meet code on the first submission. This timeline includes reviews by the Planning Department for zoning compliance, the Building Department for structural and life safety, and potentially Public Works for utility connections. Delays can occur if plans require revisions or if specific site conditions, like stormwater management or critical areas, trigger additional reviews, which is why we emphasize thorough pre-application preparation. We guide clients through each step, ensuring all necessary documentation, like site plans, floor plans, and elevation drawings, are meticulously prepared to expedite approval.
Mighty ADU Company most commonly uses either a reinforced concrete slab-on-grade or a conventional crawl space foundation for ADUs in Tigard, depending on site conditions and client preference. A slab-on-grade foundation is often chosen for its cost-effectiveness and thermal mass benefits, especially when integrated with radiant floor heating, because it provides a solid, level base directly on the ground. A crawl space, on the other hand, allows for easier access to plumbing and electrical systems post-construction and can be beneficial on sloped lots or where soil conditions require deeper footings, which means we can adapt to various topographical challenges. We always conduct a geotechnical assessment to determine the best foundation solution for your specific property's soil characteristics and drainage patterns.
