Common Uses in Round Rock
Local Intelligence
What Round Rock Homeowners Need to Know Before Submitting
Size & Zoning Rules
0Round Rock 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 Round Rock who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,229/month.
Permit Process & Fees
Planning and Development Services permit fees for this project type typically range from $17,840 to $23,383 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 Planning and 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 and Development Services ↗Construction Cost Context
Round Rock's adu / renovation construction costs run $180–$252 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 Round Rock
Round Rock's Planning and Development Services will often kick back ADU plans if your lot was platted under an older Williamson County subdivision agreement with deed restrictions that predate the city's current ADU ordinance — many homeowners don't discover this conflict until after they've paid for architectural drawings. Because the city requires a separate impervious cover calculation tied to your original plat, adding a detached ADU can trigger a drainage review if your lot is already near its coverage limit, which is common in older neighborhoods near downtown. On top of that, since short-term rentals aren't allowed here, some lenders in the area won't count projected rental income toward your ADU financing, which catches a lot of owners off guard when they're budgeting the $220/sqft build cost.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience working with Round Rock homeowners, that $220/sqft and 6-week timeline are state-level estimates, not gospel—I'd get at least two local contractor quotes and call Planning and Development Services directly before penciling in a budget or start date. Six weeks also assumes a clean, complete drawing set on first submittal, which I honestly don't see that often—plan on corrections adding a few weeks to your real-world schedule."

Common Questions
Round Rock Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Round Rock? +
You need accurate floor plans for: permit applications (required by Round Rock'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 Round Rock? +
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. Round Rock'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 Round Rock? +
Our floor plan drafting packages for Round Rock 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 Round Rock 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 Round Rock 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 Round Rock 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 Round Rock? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Round Rock. 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 Round Rock? +
In Round Rock, where median home values are around $380,000, 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 Round Rock? +
Yes — Round Rock'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 Round Rock? +
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 Round Rock homes built before the 1990s.
