Understanding Kirkland ADU Regulations

Building an ADU in Kirkland requires navigating specific zoning and permitting rules. Our team is well-versed in local regulations, ensuring your project complies with:

  • Setback and Height Rules: Compliance with setback distances and height restrictions for detached units.

We handle all permitting and inspections, so you don’t have to worry about navigating complex regulations.

Cost of Building an ADU in Kirkland

The cost of an ADU varies based on size, type, and finishes. On average, Kirkland ADUs range from $150,000 to $350,000, including design, permitting, and construction. Factors affecting cost include:

  • ADU Type: Detached units are typically more expensive than basement or garage conversions.

  • Size and Layout: Larger or more complex designs increase costs.

  • Materials and Finishes: Premium fixtures, flooring, or energy-efficient systems add value but raise costs.
