Common Uses in Richardson
Local Intelligence
What Richardson Homeowners Need to Know Before Submitting
Size & Zoning Rules
0Richardson 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 Richardson who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,392/month.
Permit Process & Fees
Building Inspection permit fees for this project type typically range from $2,000 to $8,000 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 Building Inspection 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 Building Inspection ↗Construction Cost Context
Richardson's adu / renovation construction costs run $182–$273 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 Richardson
Richardson's Building Inspection division requires a separate plumbing permit review if your ADU adds a new sewer tap, and older neighborhoods east of Central Expressway often have clay sewer laterals that trigger a mandatory camera inspection before the city will approve the connection. If that inspection finds root intrusion or cracks — common in homes built before the 1980s — you're looking at a lateral repair that can add $5,000-$10,000 and several weeks before your ADU permit even moves forward. Also, many Richardson subdivisions still carry deed-restriction HOAs that predate the city's ADU-friendly zoning, so the city may approve your plans while your HOA separately blocks or delays construction over setback or "accessory structure" language in the covenants.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Richardson permit reviewers, that 6-week timeline is best-case for a clean, correction-free set—plan check backlogs routinely add 3-4 weeks when revisions are needed, so I wouldn't pencil in a start date until you've confirmed current queue times with Building Inspection. The $260/sqft figure also reads as a state-level estimate rather than a Richardson-specific number, so get two or three local contractor quotes before you budget against it. —Charlotte Pemberton, Senior ADU Design Consultant"

Common Questions
Richardson Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Richardson? +
You need accurate floor plans for: permit applications (required by Richardson'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 Richardson? +
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. Richardson'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 Richardson? +
Our floor plan drafting packages for Richardson 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 Richardson 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 Richardson 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 Richardson 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 Richardson? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Richardson. 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 Richardson? +
In Richardson, where median home values are around $430,000, 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 Richardson? +
Yes — Richardson'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 Richardson? +
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 Richardson homes built before the 1990s.
