Understanding Accessory Dwelling Units (ADUs)

An Accessory Dwelling Unit (ADU) is essentially a complete, independent living area located on the same property as your main home. Think of it as a mini-home with its own entrance, kitchen, and bathroom. These versatile spaces can be built right into your existing house, attached to it, or stand alone as a separate structure in your yard.

You might hear ADUs called by many names, such as:

  • Mother-in-law suites
  • Vacation rentals
  • Backyard cottages
  • Granny flats
  • Carriage houses

The potential of an ADU is truly vast. It's about crafting a space that perfectly fits your life. Whether your goal is to earn extra income through rentals, provide a comfortable place for family members, or simply boost your property's overall worth, an ADU is a fantastic way to enhance your home and lifestyle.

ADUs For Rental Properties

In the thriving housing markets of Seattle, Tacoma, and King County, where demand and costs continue to rise, Accessory Dwelling Units (ADUs) and Detached Accessory Dwelling Units (DADUs) are excellent solutions for increasing housing density and affordability. Building one unlocks a powerful new stream of rental income, significantly boosting your property's value and appeal. Our expert team designs and builds ADUs that seamlessly complement your existing home, making them a wise investment for rentals or future sale, promising substantial returns.

Local Code Expertise For Your ADU Project

Navigating the complexities of local building codes and zoning laws for an Accessory Dwelling Unit (ADU) can be challenging. As your professional contractors, we simplify this process, guiding you through permits and compliance every step of the way.

In Seattle, most homeowners can build two ADUs on their property. You have the flexibility to:

  • Integrate both as attached or internal units (AADUs) within your main home
  • Choose a combination of one AADU and one detached ADU (DADU).

We'll help you determine the best use of your space, designing a sustainable solution that aligns with your lifestyle and budget.

Collaborative Design Process

At Masis General Contractor, we believe every successful remodel starts with a thoughtful conversation. We start by listening—really listening—to understand your goals and vision for the project. Our collaborative design process ensures that every detail is tailored precisely for you. We'll guide you in choosing materials, finishes, and layouts that are not only beautiful but also built to last, resulting in a stunning and highly functional ADU. To ensure we exceed your expectations, we'll discuss:

  • Top Goals and Priorities for ADU: Will this be used as a rental property or for personal use? Are you looking to create a comfortable space for a loved one, or perhaps a functional area for your adult children? We'll work with you to create a plan that makes the biggest impact.
  • The ideal feel and layout: Are you looking for open spaces, clever storage, or seamless flow to other rooms?
  • Your project budget: We'll craft a plan that aligns with your financial goals without compromising on quality.
  • Your style preference: Are you aiming for a modern refresh, or a luxurious retreat? We understand how strategic updates can elevate your space.
