What Auburn Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Auburn — Community Development will not accept a permit application without them. Auburn's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Auburn 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 Auburn who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,553/month.
Permit Process & Fees
Community Development permit fees for this project type typically range from $9,319 to $15,728 depending on project valuation and scope. Plan check runs approximately 5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to 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 Community Development ↗Construction Cost Context
Auburn's adu / renovation construction costs run $193–$315 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 Auburn
Auburn's Community Development department requires structural plans stamped by a Washington-licensed engineer specifically addressing Seismic Design Category D2 requirements, and reviewers routinely kick back generic prefab ADU plans that don't show local hold-down and shear wall calculations for our soil conditions. Because many Auburn lots sit on older King County sewer lines from the 1960s-70s, you'll often need a sewer scope inspection before permit approval, and if roots or cracks show up, that's an unplanned $5,000-$15,000 repair before your ADU can even break ground. Also, if you're planning to use the ADU as a short-term rental, Auburn requires a separate business license and annual fire inspection on top of the building permit, which catches a lot of investors off guard after they've already budgeted just for construction.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Auburn submittals, that 5-week plan check figure is optimistic for most first-time applicants—incomplete drawing sets are the norm, not the exception, and I've routinely seen review stretch to 8-10 weeks once corrections come back. On costs, the $275/sqft looks like a state-level estimate rather than a true Auburn number, so I'd get at least two local contractor quotes and call Community Development directly before locking in a budget or timeline."
Market Context
Auburn has a median home value of $541,000. Comparable renovation projects in this market typically add 28.0% to resale value.
Neighborhoods in Auburn with the strongest renovation and resale value potential include Lea Hill, Downtown Auburn, North Auburn, West Hill-Midway, South Auburn. High rental demand from Green River College students and large lot sizes make this ideal for detached units.
Permit Process
Permit applications are reviewed by the Community Development, with a plan check timeline of approximately 5 weeks. Permit fees in Auburn range from $9,319 to $15,728 depending on project scope.
Auburn falls within Seismic Design Category Seismic Design Category D (D2 Residential) per ASCE 7 (City of Auburn local code), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Auburn Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Auburn? +
You need accurate floor plans for: permit applications (required by Auburn'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 Auburn? +
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. Auburn'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 Auburn? +
Our floor plan drafting packages for Auburn 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 Auburn 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 Auburn 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 Auburn 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 Auburn? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Auburn. 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 Auburn? +
In Auburn, where median home values are around $541,000, 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 Auburn? +
Yes — Auburn'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 Auburn? +
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 Auburn homes built before the 1990s.
