Local Intelligence
What McKinney Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in McKinney — Development Services will not accept a permit application without them. McKinney's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
McKinney 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 McKinney who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,402/month.
Permit Process & Fees
Development Services permit fees for this project type typically range from $516 to $756 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 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 Development Services ↗Construction Cost Context
McKinney's adu / renovation construction costs run $161–$226 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 McKinney
Many McKinney neighborhoods built after the 1990s carry HOA deed restrictions that flat-out ban detached ADUs or require them to match brick specs on the primary home, so Development Services approval doesn't mean much if your HOA board hasn't signed off separately — and that review can take longer than the permit itself. Older lots near downtown often still run on shared or undersized sewer laterals, so the city may require a sewer tap capacity check before approving your ADU plumbing, which can add a few weeks if Collin County records for that line are incomplete. Because McKinney allows short-term rentals, be aware the city also requires a separate STR registration and inspection after your certificate of occupancy — skipping that step is a common reason new ADU owners get fined before their first guest even checks in.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with McKinney submittals, that $230/sqft figure and the 6-week timeline are really state-level averages, not McKinney-specific numbers — I'd get quotes from two or three local contractors and call Development Services directly before penciling in a budget or schedule. I've also seen plenty of "6-week" projects stretch to 10+ weeks once a drawing set comes back with corrections, and with HOAs covering 75% of neighborhoods here, don't forget that architectural review board timeline runs separately from the city's clock."

Common Questions
McKinney Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in McKinney? +
You need accurate floor plans for: permit applications (required by McKinney'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 McKinney? +
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. McKinney'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 McKinney? +
Our floor plan drafting packages for McKinney 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 McKinney 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 McKinney 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 McKinney 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 McKinney? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in McKinney. 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 McKinney? +
In McKinney, where median home values are around $421,000, 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 McKinney? +
Yes — McKinney'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 McKinney? +
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 McKinney homes built before the 1990s.
