Expert ADU Builder in Kenmore: Maximize Your Property
An ADU in Kenmore can do real work for the property. It can bring in rental income, make room for family, or turn underused square footage into something that pays you back every month. Kenmore adopted updated ADU regulations in June 2025, and local permit review can pull in critical-area issues like streams, wetlands, lakes, and steep slopes. That is where loose planning gets expensive. We check the site first, then build the plan around what is actually there.

How It Works
Our Process
Site Assessment
We review lot size, setbacks, access, utilities, and site limits first, because in Kenmore the land often decides whether the best path is an ADU, garage conversion, or basement conversion.
Custom Design
Then we build a layout that fits the existing house, preserves privacy, and solves circulation cleanly. Good plans save money. Bad plans hide it until framing.
Permitting
We prepare the permit package, coordinate city review, and flag critical-area issues early if the property is near wetlands, streams, lakes, or steep slopes.
Construction
From structural work through framing, insulation, utilities, and finishes, our crew builds the ADU in a tight sequence with close field control and clean scheduling.
Turnkey Delivery
After inspections pass, we finish the last details and hand over a completed ADU ready for family use, guests, or long-term rental. No loose ends.

FAQ
Frequently Asked Questions About ADU Remodeling in Kenmore
Planning an ADU project in Kenmore comes with many questions about permits, timelines and budget. Below we cover the most common concerns homeowners have. Feel free to reach out for a personalized consultation and clear guidance specific to your Kenmore property.
How much does it cost to build an ADU?
The cost depends on size, structural work, utility tie-ins, site prep, and finish level. A simple basement conversion usually lands lower than a full garage conversion or new attached build. In Kenmore, critical-area review or utility coordination can move the number fast. We price from the real property, not online averages.
Do I need permits for an ADU in Kenmore?
Yes. ADU work in Kenmore goes through the city permit process, and some projects also trigger critical-area review or related agency coordination. Permits are submitted through MyBuildingPermit. We handle that path from submittal through comments and inspections.
Can I build an ADU on my specific lot?
Maybe, but we do not guess from parcel photos. We check setbacks, utility access, lot layout, and whether the site is affected by wetlands, streams, lakes, steep slopes, or tree restrictions. On some Kenmore properties, those issues matter more than square footage.
Why choose our company as your ADU builder?
Because ADU projects usually break at the handoff points. Design says one thing, permitting says another, and the field has to absorb the mistake. We keep the process under one roof from feasibility through final delivery. That cuts miscommunication, protects the budget, and gives you a better-built result.
