Local Intelligence
What Denver Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Denver — Community Planning and Development will not accept a permit application without them. Denver's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Denver currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
Homeowners in Denver who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,588/month.
Permit Process & Fees
Community Planning and Development permit fees for this project type typically range from $2,200 to $8,500 depending on project valuation and scope. Plan check runs approximately 51 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Community Planning and 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 Planning and Development ↗Construction Cost Context
Denver's adu / renovation construction costs run $200–$280 per square foot — a moderate 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 Denver
Denver's zoning code caps detached ADU size based on your primary house's footprint, so CPD reviewers will actually pull your original building permit records to calculate the allowable square footage — a step that trips up a lot of owners with older homes lacking clean records. Also, if your property is on a shared water tap (common in neighborhoods like Berkeley or Sunnyside built before 1950), Denver Water will require you to upgrade to a separate tap line before they'll sign off, which can add $8,000–$15,000 and several weeks of coordination outside the normal permit timeline. Since STRs are allowed, plan for a separate STR license application through Denver's Excise and Licenses office after your certificate of occupancy — it's a distinct process that doesn't start until construction is fully closed out.
Expert Verdict — Marcus Reid, Licensed Designer
"In my 11 years pulling ADU permits in Denver, that 51-week timeline feels heavy for a straightforward build and likely reflects a worst-case queue rather than the norm — but I've also seen the $250/sqft figure undershoot reality once site conditions and finish selections come into play, so treat both as state-level estimates and get a couple of local contractor bids plus a call to Denver CPD before you budget or schedule around them."
Market Context
Denver has a median home value of $538,000. Comparable renovation projects in this market typically add 23.0% to resale value.
Neighborhoods in Denver with the strongest renovation and resale value potential include Washington Park, Platt Park, Park Hill, Congress Park, Berkeley. High single-family density, large lots and strong demand near downtown make it ideal for ADUs.
Permit Process

Common Questions
Denver Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Denver? +
You need accurate floor plans for: permit applications (required by Denver'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 Denver? +
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. Denver'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 Denver? +
Our floor plan drafting packages for Denver 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 Denver 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 Denver 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 Denver 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 Denver? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Denver. 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 Denver? +
In Denver, where median home values are around $538,000, 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 Denver? +
Yes — Denver'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 Denver? +
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 Denver homes built before the 1990s.
