Mallard Brothers Construction: ADU Builder in Olympia
Mallard Brothers Construction is an Olympia-based contractor specializing in the design and construction of Accessory Dwelling Units (ADUs) and Tiny Homes. Their team manages projects from initial planning and design through to utility connections and final construction, handling the process on behalf of the property owner.
ADUs are self-contained living spaces built on a property that already has a primary residence. Sometimes referred to as Mother-in-Law suites, granny flats, or Detached Accessory Dwelling Units (DADUs), these units typically range between 500 and 900 square feet and can comfortably accommodate one or two occupants. They serve a range of purposes — housing family members, generating rental income, or providing a private workspace.
Types of ADUs Offered
Mallard Brothers Construction offers several ADU types to suit different properties and needs:
- Attached ADUs – Connected to the main home but with private entrances, offering independence while remaining close to the primary residence.
- Detached ADUs (DADUs) – Stand-alone units that provide privacy and flexibility for guests, renters, or use as a workspace.
- Garage Conversions – Converting an existing garage into a livable space, with attention to Thurston County codes regarding wells and septic systems.
- Custom Tiny Homes – Eco-friendly and efficient designs focused on minimal living without sacrificing basic comfort.
- ADA-Accessible ADUs – Units designed for aging in place, incorporating features such as wider doorways, ramps, and barrier-free showers to support varying mobility needs.
For properties within Olympia city limits, Mallard Brothers can work with Olympia's Preapproved ADU plan sets. Selecting from one of these four designs can reduce permitting time and help avoid additional engineering costs, potentially speeding up the overall project timeline.
The ADU Building Process
Mallard Brothers approaches each ADU project as a collaborative effort with the property owner. The process generally follows these steps:
- Initial Consultation and Feasibility Study – The team assesses the property's zoning, sewer, and septic capacity to determine the most suitable approach.
- Design and Planning – Clients can choose from preapproved plans or work with the design team to develop a custom layout.
- Permits and Approvals – Mallard Brothers handles the necessary permits and ensures the project meets all relevant regulations.
- Construction and Finalization – From utility connections to finishing details, the team completes the build and prepares the unit for occupancy.
Customization options are available across both interior and exterior elements. These include vaulted ceilings, cedar detailing, and custom finishes, as well as outdoor additions like covered decks or saunas. Energy-efficiency features such as solar panels and sustainable materials are also available for those looking to reduce their environmental footprint.
Mallard Brothers Construction works with clients whether they are starting from a preapproved plan or require a fully customized accessory dwelling unit built to specific requirements. Their focus is on durable materials, functional layouts, and integration with the existing property style.
