Local Intelligence
What Redmond Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Redmond — Development Services Center will not accept a permit application without them. 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.
Homeowners in Redmond who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,274/month.
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.
Floor plans submitted to Development Services Center as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Development Services Center ↗Construction Cost Context
Redmond's adu / renovation 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 renovation and resale value 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 any new addition tying into the existing structure.

Common Questions
Redmond Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Redmond? +
You need accurate floor plans for: permit applications (required by Redmond's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Redmond? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Redmond's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Redmond? +
Our floor plan drafting packages for Redmond start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Redmond home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Redmond neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Redmond building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Redmond? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Redmond. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Redmond? +
In Redmond, where median home values are around $1,100,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Redmond? +
Yes — Redmond's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Redmond? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Redmond homes built before the 1990s.
