Local Intelligence
What Kennewick Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Kennewick — Community Planning Department — Building Safety Division will not accept a permit application without them. Kennewick's current ADU size cap is 1,100 sq ft — within the typical range for most floor plan configurations.
Homeowners in Kennewick who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,302/month.
Permit Process & Fees
Community Planning Department — Building Safety Division 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 Community Planning Department — Building Safety Division 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 Community Planning Department — Building Safety Division ↗Construction Cost Context
Kennewick's adu / renovation construction costs run $200–$510 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 Kennewick
Kennewick's Building Safety Division will flag most older Southridge and Vista lots for a separate Irrigation District release before they'll issue your permit, since a chunk of the city still gets water rights through Kennewick Irrigation District rather than straight city water — homeowners routinely lose 2-3 weeks tracking down that paperwork because it's not mentioned on the standard checklist. You'll also want to budget for a new sewer side-sewer inspection if your lot was platted before the 1990s, since Benton County records on old clay pipe connections are spotty and the city won't sign off until a camera scope confirms the line can handle a second unit. Because Kennewick sits in SDC C, expect your engineer to add shear wall details even for a single-story ADU, which is a common surprise cost for homeowners pulling plans from out-of-state ADU templates.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 8-week timeline and $250/sqft figure are really state-level averages dressed up as Kennewick-specific numbers, so I'd treat them as a starting point rather than a promise — get two or three local contractor quotes and call the Community Planning Department — Building Safety Division directly to check current plan check queue times before penciling in a start date. What the data also doesn't show is how much a first-round correction letter (common on ADU submittals) can push that timeline out well past two months."
Market Context
Kennewick has a median home value of $310,000. Comparable renovation projects in this market typically add 28.0% to resale value.
Neighborhoods in Kennewick with the strongest renovation and resale value potential include West Kennewick, Southridge, Canyon Lakes, Hansen Park, South Hill. Older single-family stock on larger lots close to downtown and healthcare employers makes ADUs practical and in demand.

Common Questions
Kennewick Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Kennewick? +
You need accurate floor plans for: permit applications (required by Kennewick'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 Kennewick? +
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. Kennewick'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 Kennewick? +
Our floor plan drafting packages for Kennewick 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 Kennewick 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 Kennewick 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 Kennewick 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 Kennewick? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Kennewick. 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 Kennewick? +
In Kennewick, where median home values are around $310,000, 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 Kennewick? +
Yes — Kennewick'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 Kennewick? +
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 Kennewick homes built before the 1990s.
