Local Intelligence
What Boulder Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Boulder — Planning & Development Services will not accept a permit application without them. Boulder's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Boulder 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 Boulder who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,700/month.
Permit Process & Fees
Planning & Development Services permit fees for this project type typically range from $22,977 to $25,469 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Planning & 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 & Development Services ↗Construction Cost Context
Boulder's adu / renovation construction costs run $168–$269 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 Boulder
Boulder's Residential Growth Management system caps how many detached units can get building permits each year, so even a fully compliant ADU application can sit in a queue behind other projects citywide. Because short-term rentals are banned here, Planning & Development Services will also require you to sign a deed restriction affirming long-term occupancy only, which some lenders and title companies flag during refinancing. On top of that, many older Boulder neighborhoods still run on shared sewer laterals, so you'll likely need a sewer scope inspection before the city signs off on utility connections — a step that catches most homeowners off guard.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $210/sqft and the 6-week plan check are Boulder state-level averages, not numbers I'd bank on for your specific lot — I'd call Planning & Development Services directly and get at least two local contractor quotes before penciling out your budget. I've also seen plenty of "6-week" submittals stretch to 10-12 weeks once corrections come back, especially if the drawing set isn't fully dialed in on the first pass."
Market Context
Boulder has a median home value of $860,000. Comparable renovation projects in this market typically add 23.0% to resale value.
Neighborhoods in Boulder with the strongest renovation and resale value potential include University Hill, Old North Boulder, Newlands, West Pearl, Mapleton Hill. Extremely strong rental demand from CU Boulder students and faculty, making small ADUs highly rentable.
Permit Process
Permit applications are reviewed by the Planning & Development Services, with a plan check timeline of approximately 6 weeks. Permit fees in Boulder range from $22,977 to $25,469 depending on project scope. Design review: Yes - in historic districts/individually designated historic properties only (otherwise ADUs are approved through standard building permit process).
Boulder falls within Seismic Design Category B, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Boulder Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Boulder? +
You need accurate floor plans for: permit applications (required by Boulder'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 Boulder? +
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. Boulder'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 Boulder? +
Our floor plan drafting packages for Boulder 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 Boulder 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 Boulder 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 Boulder 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 Boulder? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Boulder. 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 Boulder? +
In Boulder, where median home values are around $860,000, 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 Boulder? +
Yes — Boulder'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 Boulder? +
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 Boulder homes built before the 1990s.
