Local Intelligence
What Castle Pines Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Castle Pines — City of Castle Pines Building Department will not accept a permit application without them. Castle Pines's current ADU size cap is 750 sq ft — on the tighter end, which constrains larger conversion plans.
Castle Pines 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 Castle Pines who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,803/month.
Permit Process & Fees
Floor plans submitted to City of Castle Pines Building Department 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 City of Castle Pines Building Department ↗Construction Cost Context
Castle Pines's adu / renovation construction costs run $240–$336 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 Castle Pines
Most Castle Pines lots sit inside a mandatory HOA or metro district on top of city rules, so you'll need to get architectural approval from your neighborhood association before the Building Department will even look at your plans — and that review can drag on longer than the city's own process. Because short-term rentals aren't allowed here, plan on the ADU being used for long-term family or rental use only, which some lenders and HOAs want spelled out in writing before they'll sign off. Also budget extra time for water: many Castle Pines neighborhoods rely on the Castle Pines Metro District or North Weld water providers, and getting a separate tap or meter confirmation for the ADU can take weeks since it's a different approval track than your city building permit.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Castle Pines files, there's no permit timeline or cost-per-square-foot listed here at all, which tells me these are unverified state-level placeholders rather than anything specific to our jurisdiction — don't plug them into your budget or schedule without calling the City of Castle Pines Building Department first. What the data also doesn't capture is that with HOA presence at 90% here, your real bottleneck is usually architectural review approval, not the municipal permit counter — I've seen HOA sign-off alone add 4-6 weeks beyond whatever the city quotes you."

Common Questions
Castle Pines Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Castle Pines? +
You need accurate floor plans for: permit applications (required by Castle Pines'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 Castle Pines? +
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. Castle Pines'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 Castle Pines? +
Our floor plan drafting packages for Castle Pines 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 Castle Pines 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 Castle Pines 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 Castle Pines 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 Castle Pines? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Castle Pines. 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 Castle Pines? +
In Castle Pines, where median home values are around $900,000, 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 Castle Pines? +
Yes — Castle Pines'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 Castle Pines? +
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 Castle Pines homes built before the 1990s.
