  1. Zoning: Verify if your property is in a zone permitting ADUs and additions. Local zoning ordinances dictate the units allowed, such as attached, detached, or conversions.
  2. Setbacks: Projects must adhere to setback requirements, which define the minimum distance between the tiny home and property lines. These requirements may differ for front, side, and rear yard setbacks.
  3. Maximum unit size: Local ordinances often impose limitations on the full scope of the addition. These limits can be expressed as a percentage of the primary dwelling unit’s size or an absolute square footage cap.
  4. Height restrictions: Some jurisdictions impose height limits, particularly for detached units, to maintain neighborhood aesthetics and privacy.
  5. Parking: Homeowners may be required to provide additional off-street parking spaces for occupants. However, some cities may waive this requirement if the property is near public transit.
  6. Owner occupancy: Certain jurisdictions mandate that the property owner resides in either the primary dwelling or the Accessory Dwelling Units, ensuring that at least one of the units is owner-occupied.
  7. Building code compliance: Must meet local and state building codes, including energy efficiency, fire safety, and accessibility standards.
  8. Utility connections: Homeowners should consider the costs and requirements of connecting to existing or separate utility services, such as water, sewer, and electricity.

ADU Financing Options

Financing an Accessory Dwelling Unit in WA can be accomplished through various means. Here are some options to consider when planning your project:
  1. Home Equity Loans or Lines of Credit (HELOC): If you have built up equity in your home, you can leverage it to finance your project. Home equity loans offer a lump sum, while HELOCs provide a revolving line of credit, allowing you to borrow as needed during construction.

  3. Construction Loan: Some lenders offer construction loans designed specifically for home improvement projects. These loans are typically short-term and may have higher interest rates than traditional mortgage loans. Still, they can provide the necessary funds for your project.
  4. Personal Loans: Unsecured personal loans can also finance an Accessory Dwelling Unit. While they may have higher interest rates and shorter repayment terms than secured loans, they can be an option for homeowners who do not wish to use their homes as collateral.
  5. Savings and Investments: If you have adequate savings or investments, using these funds to finance your backyard home can help you avoid loan interest charges.
  6. Government Programs and Grants: Depending on your location and circumstances, you may be eligible for government programs, grants, or low-interest loans to promote affordable housing or energy-efficient construction. These programs may have specific requirements and application processes, so it is essential to research and verify your eligibility.
  7. Family Loans or Partnerships: Sometimes, family members or friends may be willing to lend you money for your project as a loan or a partnership agreement where they share in the rental income or increased property value.
Researching and comparing different financing options is essential to determine the best fit for your specific situation and needs. Consult with financial professionals or mortgage brokers to explore the various financing avenues.

Types of ADU

Attached ADU

A small apartment unit built as an add-on to your home, sharing at least one wall with the primary building. An attached unit usually connects to the primary structure’s water and power lines, but it provides for all independent living needs. The best thing about a detached ADU is its separate entrance. As such, if you live on a property with limited available space, an attached ADU could be a great solution.

Detached ADU

A detached ADU is an independent structure that stands and functions as its own house, albeit smaller than the primary home. It includes all the necessary amenities for its inhabitants. Most ADU laws, stipulate that if you wish to build a detached ADU, you need to set aside an area of your property and create good boundaries to provide the unit’s residents with privacy. Large detached ADUs can often earn high rental rates because they offer renters more flexibility.

Garage Conversion

Garage conversions are trendy ideas for maximizing your property's earning potential. As the name suggests, a garage conversion is simply a remake of what already exists - namely, an attached or detached garage. Converting your garage area can give you much-needed living space or gain you regular extra income!

Above Garage ADU

An Above Garage-Attached Dwelling Unit (ADU) provides an affordable option for homeowners looking to rent out their space while still being able to use their garage. By installing an ADU on top of your current garage, you'll have plenty of extra room for tenants without giving up the much-needed parking and storage space.

Interior Conversion

A converted space inside your house, letting you create your own tiny home within a home. Interior ADUs are, as with all ADUs, meant to be independent living quarters. Therefore, these spaces require plumbing and ventilation for the unit's separate kitchen and bath, and they will most likely share utility services and mechanical appliances with the central unit. Currently, these units are the most common form of ADU homes as they're easy to maintain and affordable. So don't hesitate to think about building one!

Junior ADU (JADU)

A Junior Accessory Dwelling Unit (JADU) is the Single Family ADU’s (the standard ADU) little sibling but has different restrictions to help keep costs down while ensuring that they provide adequate living facilities. For example, a JADU can only be built as part of a single-family home, existing or proposed single-family home, or within an accessory structure, such as a detached garage or carport. A JADU shares utilities and mechanical appliances with the main house.
