Local Intelligence
What Southlake Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Southlake — Planning & Development Services will not accept a permit application without them. Southlake's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Southlake 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 Southlake who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,399/month.
Permit Process & Fees
Planning & Development Services permit fees for this project type typically range from $750 to $1,250 depending on project valuation and scope.
Floor plans submitted to Planning & 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 Planning & Development Services ↗⚠ Common Pitfall in Southlake
Most Southlake ADU projects get tripped up by the city's strict lot coverage and masonry ordinance long before anyone looks at your floor plan — homes here typically require 80% masonry on exterior walls, which can push your build cost well past that $350/sqft average if your ADU doesn't match the main house's stone or brick. Because Southlake bans short-term rentals outright, plan reviewers also check your application for language suggesting Airbnb-style use, so your permit narrative and site plan need to clearly state long-term family or guest use to avoid a rejection loop. On top of that, since fee data and review timelines vary wildly depending on whether staff routes your project as an "Addition" or standalone structure, it's worth calling Planning & Development Services directly before submittal to confirm which track you're on — guessing wrong can cost you weeks.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, both that permit timeline and the cost-per-square-foot figure you're seeing here are unverified state-level estimates, not Southlake-specific numbers — I'd call Planning & Development Services directly and get two or three local contractor quotes before you build a budget or schedule around them. With HOA coverage sitting at 55% in this area, don't overlook that an approval from the city doesn't mean your HOA architectural committee will sign off nearly as fast."
Market Context
Southlake has a median home value of $1,000,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Southlake with the strongest renovation and resale value potential include Southlake Town Square Area, Lake Woodlands, The Lakes, Southlake Estates, Hidden Lake. Highest rental demand due to immediate proximity to the city's primary dining, shopping, and employment hub.
Permit Process
Permit applications are reviewed by the Planning & Development Services. Permit fees in Southlake range from $750 to $1,250 depending on project scope.
Southlake falls within Seismic Design Category A, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Southlake Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Southlake? +
You need accurate floor plans for: permit applications (required by Southlake'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 Southlake? +
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. Southlake'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 Southlake? +
Our floor plan drafting packages for Southlake 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 Southlake 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 Southlake 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 Southlake 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 Southlake? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Southlake. 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 Southlake? +
In Southlake, where median home values are around $1,000,000, 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 Southlake? +
Yes — Southlake'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 Southlake? +
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 Southlake homes built before the 1990s.
