What Lewisville Homeowners Need to Know Before Submitting
Size & Zoning Rules

Lewisville's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Lewisville 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 Lewisville who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,301/month.
Permit Process & Fees
Building Services Division, City of Lewisville permit fees for this project type typically range from $7,496 to $11,573 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.

Visit Building Services Division, City of Lewisville ↗Construction Cost Context
Lewisville's adu / renovation construction costs run $140–$210 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 Lewisville
Lewisville's Building Services Division requires a separate plumbing permit for ADUs that tie into the main house's sewer line versus running a new lateral to the street, and many older lots in the Old Town and Vickery areas have clay pipe connections that inspectors flag on sight, forcing an unplanned upgrade before final approval. Because Lewisville sits in Denton County but pulls some utility service from Lewisville Municipal Electric or Oncor depending on the block, homeowners often discover mid-project that their meter can't handle a second unit without a service upgrade, which means a call to the utility provider that can add several weeks outside the city's own permit timeline. If you're planning to use the ADU as a short-term rental, know that the city still requires it to pass the same fire separation and egress inspection as a standard rental unit, so a fast STR listing plan can get stuck behind a slower construction inspection schedule.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $200/sqft figure and the 6-week plan check window are both statewide averages rather than verified Lewisville numbers, so I'd call Building Services Division, City of Lewisville and get two or three local contractor quotes before you anchor your budget or schedule to them. Even with a strong drawing set, I've seen review times stretch past 6 weeks once corrections come back, so build in a buffer rather than planning around the best-case scenario."

Common Questions
Lewisville Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Lewisville? +
You need accurate floor plans for: permit applications (required by Lewisville'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 Lewisville? +
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. Lewisville'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 Lewisville? +
Our floor plan drafting packages for Lewisville 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 Lewisville 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 Lewisville 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 Lewisville 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 Lewisville? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Lewisville. 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 Lewisville? +
In Lewisville, where median home values are around $330,000, 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.

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 Lewisville? +
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 Lewisville homes built before the 1990s.
