Building ADUs in Wenatchee & East Wenatchee
Cascade Master Builders is a contractor based in Wenatchee, Washington, specializing in the design and construction of Accessory Dwelling Units (ADUs) — also referred to as backyard cottages, in-law suites, or guest houses. They serve homeowners in Wenatchee, East Wenatchee, and the surrounding areas of North Central Washington.
An ADU is a self-contained residential unit built on the same property as a primary residence. It includes its own kitchen, bathroom, and living space, making it suitable for independent living. ADUs can take several forms:
- Detached ADUs — a separate structure in the backyard
- Attached ADUs — an addition connected to the existing home
- Over-garage or basement units
Homeowners in the Wenatchee Valley are adding ADUs for a range of practical reasons, including generating rental income, providing private housing for family members, increasing property value, and contributing to the region's housing supply.
Pre-Approved Plans and the Building Process
Both Wenatchee and East Wenatchee have introduced pre-approved ADU plans through their city programs. These plans are designed to reduce permitting time, lower design costs, and simplify the approval process. Cascade Master Builders has partnered with these city programs and can help homeowners select a pre-approved design or develop a fully custom ADU layout suited to their specific property and needs.
Their ADU building process generally follows these steps:
- Free Consultation & Site Review — evaluating the property and zoning to determine what is feasible
- Plan Selection — choosing from pre-approved city plans or designing a custom layout
- Permitting & Approvals — handling paperwork and coordinating with the city directly
- Construction — building the ADU according to agreed specifications and timelines
- Final Walkthrough & Move-In — completing the project ready for occupancy or rental
As an ADU contractor with local roots, Cascade Master Builders is familiar with the zoning regulations, permitting requirements, and city processes specific to the Wenatchee area. This local knowledge can be a practical advantage when navigating the approval process.
Financing Your ADU Project
Cost is often a concern for homeowners considering an ADU build. Cascade Master Builders notes that many of their clients fund construction through a Home Equity Line of Credit (HELOC) or a home-equity loan. The general approach involves using existing home equity to finance the project, with the expectation that rental income from the completed ADU can help offset loan repayments.
The team also has experience as licensed real-estate professionals, which means they can help clients work through the financial side of an ADU project and connect them with local lenders familiar with ADU financing.
As an accessory dwelling unit builder offering complete project management — from initial site review through to final inspection — Cascade Master Builders positions itself as a single point of contact for the entire ADU construction process. Their service area covers Wenatchee, East Wenatchee, and surrounding communities in North Central Washington.
