Local Intelligence
What Centennial Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Centennial — Building Division will not accept a permit application without them. Centennial's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Centennial 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 Centennial who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,767/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $1,786 to $3,638 depending on project valuation and scope. Plan check runs approximately 2.2 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
Centennial's adu / renovation construction costs run $210–$320 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 Centennial
Since Centennial incorporated fairly recently and shares plan review staff with Arapahoe County for certain services, many homeowners get tripped up submitting to the wrong desk — your ADU application goes through the city's Building Division, but septic or well-related sign-offs (common in older Centennial neighborhoods that predate city water hookups) still route through Arapahoe County Environmental Health, adding a parallel approval track most people don't discover until their permit stalls. HOAs in Centennial's many planned communities, especially in areas like Piney Creek and Homestead, often have separate architectural review committees that require approval before you even file with the city, and they can reject exterior materials or roof pitch even if the Building Division has no issue with your plans. Because STRs aren't allowed here, some lenders and title companies also ask for a signed affidavit confirming the ADU won't be rented short-term, which can slow down financing if your loan officer isn't familiar with the local rule.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 2.2-week plan check timeline and $300/sqft build cost are Centennial state-level estimates, not verified local figures — I'd get quotes from at least two local contractors and call the Building Division directly before penciling in a schedule. Also, with 40% of the area under HOA control, don't sleep on architectural review adding its own delay on top of whatever the city quotes you."

Common Questions
Centennial Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Centennial? +
You need accurate floor plans for: permit applications (required by Centennial'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 Centennial? +
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. Centennial'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 Centennial? +
Our floor plan drafting packages for Centennial 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 Centennial 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 Centennial 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 Centennial 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 Centennial? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Centennial. 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 Centennial? +
In Centennial, where median home values are around $548,000, 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 Centennial? +
Yes — Centennial'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 Centennial? +
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 Centennial homes built before the 1990s.
