Local Intelligence
What Tacoma Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Tacoma — Planning and Development Services will not accept a permit application without them. Tacoma's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Tacoma 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 Tacoma who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,496/month.
Permit Process & Fees
Planning and Development Services 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 Planning and Development Services 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 Planning and Development Services ↗Construction Cost Context
Tacoma's adu / renovation construction costs run $196–$490 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 Tacoma
If your lot falls within Tacoma's Shoreline District — which covers a lot more ground near Commencement Bay and the Thea Foss waterway than most homeowners realize — you'll need a Shoreline Substantial Development Permit on top of your standard ADU review, and that Coastal Development Permit process alone can tack on 6-8 extra weeks while the state Department of Ecology gets a comment period. Because Tacoma sits in Seismic Zone D1, Planning and Development Services will also scrutinize your foundation plans closely if you're building a detached ADU on a lot with any slope, often requiring a licensed engineer's stamp before they'll even schedule plan review. On top of that, Pierce County's side sewer connection rules mean older Tacoma neighborhoods (especially the North End and parts of Hilltop) may need a sewer scope inspection to prove your existing line can handle a second unit — a step that catches almost everyone off guard and can add another few weeks if the line needs work.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 8-week timeline and $280/sqft figure are Tacoma state-level estimates, not gospel — I'd get a couple of local contractor quotes and call Planning and Development Services directly before penciling in a budget or move-in date. What the data also glosses over is that your coastal overlay triggers a CDP review, which in my experience with Tacoma waterfront-adjacent parcels can tack on months, not weeks, so don't count on that STR income starting anytime soon. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Tacoma Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Tacoma? +
You need accurate floor plans for: permit applications (required by Tacoma'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 Tacoma? +
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. Tacoma'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 Tacoma? +
Our floor plan drafting packages for Tacoma 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 Tacoma 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 Tacoma 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 Tacoma 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 Tacoma? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Tacoma. 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 Tacoma? +
In Tacoma, where median home values are around $389,000, 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 Tacoma? +
Yes — Tacoma'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 Tacoma? +
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 Tacoma homes built before the 1990s.
