Local Intelligence
What Kent Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Kent — Economic & Community Development will not accept a permit application without them. Kent's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Kent does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Kent who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,500/month.
Permit Process & Fees
Economic & Community Development permit fees for this project type typically range from $3,000 to $11,000 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 Economic & Community Development 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 Economic & Community Development ↗Construction Cost Context
Kent's adu / renovation construction costs run $350–$560 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 Kent
Kent's Economic & Community Development department requires a separate side sewer inspection through the City before they'll sign off on your ADU, and if your home is on an older section of pipe (common in the East Hill and Panther Lake areas), you may get flagged for a full sewer line replacement rather than a simple tie-in. Because Kent sits in Seismic Design Category D2, engineers often need to add extra shear wall bracing or hold-down hardware for detached ADUs, which can quietly add a few thousand dollars that generic online cost estimates never mention. Also, if you're planning to use the ADU as a short-term rental, Kent requires a separate business license and lodging tax registration on top of the building permit — a step many homeowners don't discover until after construction is done.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Kent permits, that 8-week timeline is best-case and assumes zero correction cycles — I've rarely seen a first submittal sail through, so budget an extra 3-4 weeks for review comments; and that $500/sqft figure is a state-level estimate, not a Kent-specific quote, so I'd call a couple of local contractors and Economic & Community Development directly before you pencil out your budget."
Market Context
Kent has a median home value of $522,000. Comparable renovation projects in this market typically add 28.0% to resale value.
Neighborhoods in Kent with the strongest renovation and resale value potential include East Hill, Meridian, Scenic Hill, Lake Meridian, West Hill. Large single-family lots, strong commuter demand and competitive housing market make ADUs profitable.
Permit Process
Permit applications are reviewed by the Economic & Community Development, with a plan check timeline of approximately 8 weeks. Permit fees in Kent range from $3,000 to $11,000 depending on project scope. Design review: No (except potential review for landmark/historic properties).
Kent falls within Seismic Design Category Seismic Design Category D2 (per Washington state SDC maps; site-specific SDS/site-class may alter the category), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Kent Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Kent? +
You need accurate floor plans for: permit applications (required by Kent'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 Kent? +
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. Kent'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 Kent? +
Our floor plan drafting packages for Kent 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 Kent 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 Kent 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 Kent 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 Kent? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Kent. 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 Kent? +
In Kent, where median home values are around $522,000, 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 Kent? +
Yes — Kent'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 Kent? +
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 Kent homes built before the 1990s.
