Why Everett Is a Top Location for ADUs

Everett’s flexible zoning laws make it easier than ever to build ADUs. Homeowners can add one detached ADU and one Junior ADU per lot, with units up to 1,200 square feet. Most residential zones allow ADUs, and requirements for setbacks, parking, and lot size have been relaxed, making Everett one of the most ADU-friendly cities in Washington State. The city allows:

1. One detached ADU (DADU) and one Junior ADU (JADU) per lot
   
   
2. Units up to 1,200 sq ft, with relaxed height and setback requirements
   
   
3. ADUs in most residential zones, even on lots with existing garages

According to the City of Everett, ADUs are part of a larger effort to combat housing shortages and improve property utilization. Whether you're converting a garage or building from scratch, Everett’s building department offers clear guidelines to make it easy for homeowners.

Converting Your Garage into a Guesthouse

Garage conversions are one of the most popular ADU projects in Washington State, and for good reason. They’re budget-friendly, make use of existing structures, and usually involve a quicker permitting process. Converting a garage into a livable unit allows homeowners to create a rental space, guesthouse, or in-law suite, all while increasing property value and functionality. Here are the key benefits of garage conversions:

1. Cost-effective: Leverages existing structures and utilities
   
   
2. Minimal disruption: Faster build times than new construction
   
   
3. High ROI: Adds rentable square footage without major landscaping

Frequently Asked Questions

Can I convert my detached garage into an ADU in Everett?

Yes, you can convert your detached garage into an ADU if it meets Everett’s zoning requirements. These include proper setbacks from property lines, maximum square footage limits, and access to utilities like water, sewer, and electricity. Structural upgrades may also be required to meet current building codes.

What’s the average cost of building an ADU in Everett?

Building an ADU in Everett typically costs between $130,000 and $250,000 or more. The final cost depends on the unit’s size, finishes, structural complexity, and any site work needed (like utility upgrades or foundation work). For a more precise figure, use a local ADU cost calculator or consult a builder with Everett-specific experience.

Do I need parking for my ADU?

In most residential zones in Everett, you do not need to provide extra off-street parking for your ADU. This is especially true if the ADU is located within half a mile of a public transit stop. However, it's important to verify the exact parking rules based on your property’s zoning designation.

 How long does it take to build an ADU in Washington State?

From start to finish, building an ADU typically takes 6 to 12 months. This includes time for planning, architectural design, permitting through your local jurisdiction (like Everett), and construction. Delays can occur due to permitting backlogs, weather, or contractor availability, so it's smart to plan.

Is a permit required for a garage conversion?

Yes, you must obtain a building permit to convert a garage into an ADU in Everett. The project must meet the city’s current residential building codes, including rules for energy efficiency, fire safety, and structural integrity. Electrical and plumbing inspections will also be part of the permitting process.
