We’ve streamlined the ADU construction process to make it efficient, transparent, and stress-free. Here’s how we bring your Kirkland ADU to life:
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:
Size Limits: Kirkland allows ADUs up to 1,000 square feet or 60% of the primary home’s size (whichever is smaller).
Parking Requirements: Additional parking may be required, depending on your lot and ADU type.
Owner Occupancy: Kirkland may require the property owner to live on-site for certain ADU types.
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.
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.
