Common Uses in Tualatin
Local Intelligence
What Tualatin Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Tualatin — Building Division will not accept a permit application without them. Tualatin's current ADU size cap is 900 sq ft — within the typical range for most floor plan configurations.
Tualatin 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 Tualatin who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,614/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $19,885 to $30,324 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building 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 Building Division ↗Construction Cost Context
Tualatin's adu / renovation construction costs run $210–$336 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 Tualatin
Tualatin's seismic zone D designation means your engineer has to run full site-specific calculations for SDS and Seismic Design Category rather than using default tables, which often adds real engineering hours and cost before the Building Division will even log your plans as complete. Because many Tualatin lots sit on Clean Water Services (CWS) service lines rather than straight city sewer, you'll also need a separate CWS Service Provider Letter confirming capacity — a step homeowners often forget until their permit gets kicked back for missing paperwork. If your ADU is detached and near the rear property line, double-check setback allowances against Tualatin Development Code Chapter 68, since it treats detached ADUs differently from attached ones on fire separation distance.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Tualatin submittals, that 7-week plan check figure and the $300/sqft cost are both state-level estimates rather than verified local numbers, so I'd call the Tualatin Building Division directly and get a couple of local contractor bids before penciling in a budget or schedule. Even with clean plans, I've routinely seen first-round corrections push that timeline past 8 weeks, so build in a cushion. — Charlotte Pemberton, Senior ADU Design Consultant"

Permit Process

Design review: No - Planning Division land-use approval (ministerial); ARB not generally required; special overlays (e.g., historic districts) may require additional review.
Tualatin falls within Seismic Design Category Seismic Zone D (City of Tualatin states 'All of Tualatin is located in seismic zone D - Default'; designers must verify SDS and determine the Seismic Design Category per ASCE 7/OSSC), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Tualatin Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Tualatin? +
You need accurate floor plans for: permit applications (required by Tualatin'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 Tualatin? +
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. Tualatin'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 Tualatin? +
Our floor plan drafting packages for Tualatin 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 Tualatin 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 Tualatin 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 Tualatin 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 Tualatin? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Tualatin. 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 Tualatin? +
In Tualatin, where median home values are around $510,000, 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 Tualatin? +
Yes — Tualatin'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 Tualatin? +
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 Tualatin homes built before the 1990s.
