Common Uses in Westminster
Local Intelligence
What Westminster Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Westminster — Building Division will not accept a permit application without them. Westminster's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Westminster 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 Westminster who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,660/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $9,234 to $33,044 depending on project valuation and scope. Plan check runs approximately 4 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
Westminster's adu / renovation construction costs run $333–$466 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 Westminster
Westminster splits its water service between two different providers depending on which side of Sheridan or 104th you're on, and the tap fee for a new ADU water line can run anywhere from $8,000 to over $15,000 if your existing line isn't sized to handle a second unit. On top of that, the city's zoning code caps ADU size based on a percentage of your lot's buildable area rather than a flat square footage, so corner lots and older Westminster subdivisions with irregular plats often get a much smaller allowance than neighbors expect. Because Adams County still handles some records for pre-1980s annexed properties, pulling accurate lot dimensions sometimes means a trip to the county archives before Building Division will even accept your application.
Expert Verdict — Marcus Reid, Licensed Designer
"In my 11 years reviewing Westminster submittals, that 4-week plan check window and $475/sqft cost figure both read as statewide averages rather than local reality — I'd treat them as a starting point, not a promise, and call the Building Division directly for current queue times while getting at least two local contractor quotes. What the data doesn't show is how often first submittals bounce back for corrections, which routinely pushes a "4-week" review into 8-10 weeks even on a project without coastal overlay issues to contend with. — Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Westminster Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Westminster? +
You need accurate floor plans for: permit applications (required by Westminster'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 Westminster? +
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. Westminster'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 Westminster? +
Our floor plan drafting packages for Westminster 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 Westminster 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 Westminster 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 Westminster 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 Westminster? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Westminster. 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 Westminster? +
In Westminster, where median home values are around $488,000, 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 Westminster? +
Yes — Westminster'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 Westminster? +
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 Westminster homes built before the 1990s.
