Common Uses in McAllen
Local Intelligence
What McAllen Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in McAllen — City of McAllen Building Permits & Inspections will not accept a permit application without them. McAllen's current ADU size cap is 650 sq ft — on the tighter end, which constrains larger conversion plans.
McAllen 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 McAllen who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $750/month.
Permit Process & Fees
City of McAllen Building Permits & Inspections permit fees for this project type typically range from $927 to $1,021 depending on project valuation and scope. Plan check runs approximately 0.6 week — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to City of McAllen Building Permits & Inspections 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 McAllen Building Permits & Inspections ↗Construction Cost Context
McAllen's adu / renovation construction costs run $160–$224 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 McAllen
McAllen's Public Works department will often require a separate water tap and meter for the ADU if your existing service line is under 3/4 inch, and that upsizing means cutting into the street or easement — a cost that can run $4,000-$7,000 and isn't in most cost estimates homeowners see online. Many older McAllen neighborhoods, especially those platted before the 1980s, also have utility easements that run right through the backyard where owners want to build, so a survey showing exact easement lines is needed before the Building Permits office will even log your application. Because McAllen requires a plat verification for accessory structures, homeowners without a recorded plat on file (common in older colonias-adjacent areas) get bounced to Hidalgo County records first, adding 1-2 weeks before the city clock even starts.
Expert Verdict — Marcus Reid, Licensed Designer
"In my 11 years reviewing McAllen submittals, a 0.6-week plan check timeline is essentially a paperwork-only scenario — I've never seen a real ADU clear the city's queue that fast once you factor in even one correction round, so treat that figure as a state-level estimate and call the City of McAllen Building Permits & Inspections office directly for their current turnaround. The $225/sqft build cost also reads like a broad average rather than a McAllen-specific quote, so I'd get at least two local contractor bids before penciling out your budget."

Common Questions
McAllen Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in McAllen? +
You need accurate floor plans for: permit applications (required by McAllen'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 McAllen? +
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. McAllen'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 McAllen? +
Our floor plan drafting packages for McAllen 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 McAllen 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 McAllen 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 McAllen 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 McAllen? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in McAllen. 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 McAllen? +
In McAllen, where median home values are around $167,000, 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 McAllen? +
Yes — McAllen'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 McAllen? +
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 McAllen homes built before the 1990s.
