Local Intelligence
What Redmond Homeowners Need to Know Before Submitting
Size & Zoning Rules
Converting your garage to a legal rental unit means the finished space must comply with Redmond's ADU size limits. Redmond's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Redmond currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
A fully permitted, code-compliant garage conversion in Redmond can command approximately $2,274/month as a 1-bedroom rental — far more than leaving the space as storage.
Permit Process & Fees
Development Services Center permit fees for this project type typically range from $30,194 to $33,749 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Garage conversion drawings submitted to Development Services Center 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.
Visit Development Services Center ↗Construction Cost Context
Redmond's garage conversion construction costs run $245–$416 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 Redmond
Redmond's Development Services Center will kick back your ADU plans if your structural engineer hasn't specifically calibrated for Seismic Design Category D2 — many stamped plans from out-of-area engineers use lower seismic assumptions and get bounced in first review, costing you another 3-4 week cycle. Also, if your lot sits in one of Redmond's older neighborhoods like Grasslawn or Idylwood with narrow side sewer lines, expect Public Works to require a sewer capacity check before they'll sign off, since many of these lines were sized decades ago for single-family flow only. Because Redmond allows short-term rentals, you'll also want to confirm your specific parcel isn't in a zone with additional STR business license conditions layered on top of the ADU permit itself.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience reviewing Redmond ADU submittals, that $350/sqft figure reads more like a state-level average than a true local number — I'd call the Development Services Center or get two or three local contractor quotes before you budget off it. The 8-week timeline is achievable, but only with a clean, complete drawing set; I've seen plenty stretch longer once corrections come back."
Market Context
Redmond has a median home value of $1,100,000. Comparable renovation projects in this market typically add 28% to resale value.
Neighborhoods in Redmond with the strongest garage conversion and rental-unit potential include Overlake, North Redmond, Idylwood, Education Hill, Grass Lawn. Strong rental/job demand from Microsoft and other tech employers plus single-family pockets with lots suitable for detached ADUs.
Permit Process
Permit applications are reviewed by the Development Services Center, with a plan check timeline of approximately 8 weeks. Permit fees in Redmond range from $30,194 to $33,749 depending on project scope. Design review: Other: Generally No; ADUs are processed through standard building-permit (administrative) procedures and are not subject to citywide discretionary design review, but design review (Landmark/Certificate of Appropriateness or higher-level Type II/III review) can be required for properties that are designated historic landmarks or when the project triggers a land-use entitlement..
Redmond falls within Seismic Design Category Seismic Design Category D (D2 for residential) per ASCE 7 / IBC, which affects structural requirements for converted garage walls and foundations.

Common Questions
Redmond Garage Conversion FAQs
Is a garage conversion allowed in Redmond? +
Yes — garage conversions are permitted in Redmond. Washington state law allows 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 Redmond? +
Garage conversions in Redmond typically range from $130,000 to $286,000 depending on the existing structure, finish level, and scope of work. This is significantly less than building a new detached ADU. Our drawing package starts at $997 — a fraction of what a local architect would charge for the same permit-ready set.
What drawings are required to permit a garage conversion in Redmond? +
Redmond'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 (Title 24 in California). 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 Redmond? +
Plan check in Redmond typically takes approximately 8 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 Redmond? +
Yes — a permitted garage conversion can function as a standalone rental unit (ADU or JADU depending on size). In California, converted garages under 500 sq ft qualify as Junior ADUs (JADUs), while larger conversions qualify as full ADUs. Both can be rented long-term. Short-term rental rules vary by city — confirm with Redmond'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 Title 24 compliance documentation.
How much does it cost to get garage conversion drawings in Redmond? +
Our permit-ready garage conversion drawing packages for Redmond start at $997. Local architects typically charge $2,500–$6,000 for the same set. Every package is engineered for WA code compliance and formatted for Redmond's building department. Turnaround is 10 business days with a 14-day money-back guarantee.
Will converting my garage increase my home's value in Redmond? +
A permitted garage conversion in Redmond adds rentable square footage to a home currently valued around $1,100,000. 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.
