Build a Backyard Home (ADU) in Wenatchee & East Wenatchee

Increase your property value, generate rental income, and create flexible living space — all right in your backyard.

At Cascade Master Builders, we specialize in helping homeowners design and build Accessory Dwelling Units (ADUs) — also called backyard cottages, in-law suites, or guest houses. Whether you’re looking to house family, earn passive income, or make the most of your property, an ADU is one of the smartest ways to build long-term value.

🔹 What Is an ADU?

An Accessory Dwelling Unit (ADU) is a small, self-contained home built on the same property as your main residence. It includes its own kitchen, bathroom, and living space — everything needed for independent living.

ADUs can be:

  • Detached – a small home in your backyard
  • Attached – an addition to your existing house
  • Over-garage or basement units

Homeowners across Wenatchee and East Wenatchee are adding ADUs to:

  • Create rental income that offsets their mortgage
  • Provide private housing for family members
  • Boost property value and resale potential
  • Contribute to our region’s growing housing needs

🏗️ Pre-Approved ADU Plans — Faster, Simpler, and City-Ready

Both Wenatchee and East Wenatchee have introduced pre-approved ADU plans to make it easier for homeowners to build.

That means less red tape, lower design costs, and quicker permit approvals.

We’ve partnered with these city programs to make your project seamless.

You can select a pre-approved design or let us create a fully custom ADU tailored to your property and needs.

💰 Financing Made Simple — Use Your Home Equity

Don’t let cost hold you back.

Many of our clients build their ADU using a Home Equity Line of Credit (HELOC) or home-equity loan — a smart, low-interest way to fund construction.

Here’s how it works:

  • Tap your home equity to fund the project
  • Build the ADU to increase your property value
  • Rent it out to cover your loan payment — often making you cash-positive each month

We’ll guide you through the process and connect you with trusted local lenders who understand ADU financing.
