What Kenmore Homeowners Need to Know Before Submitting

Size & Zoning Rules

Converting your garage to a legal rental unit means the finished space must comply with Kenmore's ADU size limits. Kenmore's current ADU size cap is 1,500 sq ft — generous enough to accommodate most project types.

Kenmore does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.

A fully permitted, code-compliant garage conversion in Kenmore can command approximately $1,650/month as a 1-bedroom rental — far more than leaving the space as storage.

Permit Process & Fees

Garage conversion drawings submitted to Development Services must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural plans are typically required for converted garages that are detached or require seismic upgrades.

Construction Cost Context

Kenmore's garage conversion construction costs run $200–$420 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.

⚠ Common Pitfall in Kenmore

Many Kenmore lots still run on Northshore Utility District service rather than city water and sewer, so your ADU application has to clear a separate side-sewer or water availability certificate from Northshore before Development Services will even finalize your building permit. Because Kenmore sits in Seismic Zone D, engineers here also tend to require stamped calculations for foundation-to-frame connections on detached ADUs, which is a cost a lot of homeowners don't budget for when they're pricing out a simple backyard unit. If you're near one of Kenmore's older platted lots close to the Sammamish River corridor, expect extra scrutiny on critical areas review, since much of that ground falls near mapped wetlands buffers that trigger an additional environmental checklist step.

Expert Verdict — Marcus Reid, Licensed Designer

"In my 11 years working Kenmore permits, I've seen no reliable timeline or cost figures listed here at all — that blank data isn't a good sign, and I'd treat any state-level averages you find elsewhere with real skepticism until you get a local contractor quote and call Development Services directly to ask about current plan check queues. With 31% of the area under HOA governance, don't assume STR allowance at the city level means your specific property is actually clear to rent short-term."

Market Context

Kenmore has a median home value of $900,000. Comparable renovation projects in this market typically add 25% to resale value.

Neighborhoods in Kenmore with the strongest garage conversion and rental-unit potential include Central Kenmore (Downtown), Inglewood, Linwood Heights, Voucherville, Northlake Terrace. Highest rental demand due to proximity to downtown Kenmore commercial core and the Stride S3/SR 522 transit corridor connecting to Seattle.

Permit Process

Permit applications are reviewed by the Development Services.

Kenmore falls within Seismic Design Category D, which affects structural requirements for converted garage walls and foundations.

Kenmore Garage Conversion FAQs

Is a garage conversion allowed in Kenmore? +

Yes — garage conversions are permitted in Kenmore. Washington state law allow homeowners to convert an attached or detached garage into habitable living space or an ADU. A building permit and permit-ready drawings are required before work begins.

How much does a garage conversion cost in Kenmore? +

Garage conversions in Kenmore typically range from $125,000 to $275,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Contact us to discuss drawing package options for your project.

What drawings are required to permit a garage conversion in Kenmore? +

Kenmore's building department requires: a site plan showing the converted garage's location on the lot, floor plans with dimensions and room labels, all four exterior elevations, an electrical plan, and energy compliance documentation (the Washington State Energy Code). Our Starter package covers all of these. If the garage is detached or the structure requires seismic upgrades, stamped structural drawings are also required — included in our Premium package.

How long does the permit process take for a garage conversion in Kenmore? +

Plan check in Kenmore typically takes approximately 6 weeks. Having complete, code-compliant drawings dramatically reduces correction cycles — which each add 3–6 weeks. Our drawings are designed to pass on the first submittal.

Can I convert my garage into a rental unit in Kenmore? +

Yes — a permitted garage conversion can function as a standalone rental unit (an ADU, or a similar accessory-unit category depending on Washington's and Kenmore's local rules). It can be rented long-term. Short-term rental rules vary by city — confirm with Kenmore's planning department.

Do I need to replace the garage door opening when converting? +

Yes. The garage door must be replaced with an insulated wall with a standard entry door and at least one egress window (minimum 5.7 sq ft clear opening). This is captured in our elevation drawings and flagged in the electrical plan. The new wall must also meet WA energy code requirements, which we handle in the WA energy code compliance documentation.

How much does it cost to get garage conversion drawings in Kenmore? +

Our permit-ready garage conversion drawing packages for Kenmore include floor plans, elevations, electrical, and energy compliance — everything your building department needs. Every package is engineered for WA code compliance and formatted for Kenmore's building department. 14-day money-back guarantee.

Will converting my garage increase my home's value in Kenmore? +

A permitted garage conversion in Kenmore adds rentable square footage to a home currently valued around $900,000. Converted spaces typically appraise as habitable square footage, increasing the home's value. As an ADU or JADU, the rental income stream is also capitalized into the appraised value — typically at a 5–6% cap rate.
