Local Intelligence
What Des Moines Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Des Moines — Building Division will not accept a permit application without them. Des Moines's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Des Moines 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 Des Moines who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,668/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $9,000 to $28,000 depending on project valuation and scope. Plan check runs approximately 10 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
Des Moines's adu / renovation construction costs run $244–$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 Des Moines
Homes near the bluffs or shoreline in Des Moines often fall inside the state's coastal overlay zone, which means you'll need a separate Shoreline Substantial Development Permit on top of your regular building permit — this can tack on 6-8 extra weeks and requires a habitat/environmental review before the Building Division will even look at your plans. Because the city sits in Seismic Zone D, engineers also tend to require deeper footings or additional shear wall bracing than you'd see in a typical Puget Sound suburb, which can push your structural plan check costs up unexpectedly. On top of that, older neighborhoods like Woodmont and Redondo frequently have undersized side sewer lines from the 1960s, so King County may require a sewer capacity check before signing off on your final utility connection.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 10-week timeline and per-sqft cost figure are Des Moines state-level estimates rather than locally verified numbers, so I'd call the Building Division directly and get a couple of local contractor quotes before penciling in a budget or start date — and don't overlook that coastal overlay, because the CDP review adds real time on top of standard plan check that a lot of homeowners don't anticipate."
Market Context
Des Moines has a median home value of $560,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Des Moines with the strongest renovation and resale value potential include Highline College Area, Marina District, Central Des Moines, Pacific Ridge, North Hill. Extreme rental demand driven by the large student population of Highline College.
Permit Process
Permit applications are reviewed by the Building Division, with a plan check timeline of approximately 10 weeks. Permit fees in Des Moines range from $9,000 to $28,000 depending on project scope. Design review: Yes - critical area review (and historic district review if applicable).
Des Moines falls within Seismic Design Category D, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Des Moines Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Des Moines? +
You need accurate floor plans for: permit applications (required by Des Moines'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 Des Moines? +
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. Des Moines'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 Des Moines? +
Our floor plan drafting packages for Des Moines cover 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 comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Des Moines 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 Des Moines 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 Des Moines 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 Des Moines? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Des Moines. 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 Des Moines? +
In Des Moines, where median home values are around $560,000, 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 Des Moines? +
Yes — Des Moines'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 Des Moines? +
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 Des Moines homes built before the 1990s.
