Common Uses in Casselberry
Local Intelligence
What Casselberry Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Casselberry — Building Division will not accept a permit application without them. Casselberry's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Casselberry 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 Casselberry who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,481/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $690 to $1,040 depending on project valuation and scope. Plan check runs approximately 4 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building Division 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 Division ↗Construction Cost Context
Casselberry's adu / renovation construction costs run $220–$330 per square foot — a wide 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 Casselberry
Casselberry's Building Division runs the ADU permit through the same track as a standard home addition, which means Seminole County utility rules kick in fast — many older lots here still have septic systems or shared sewer laterals, and the county will require a separate capacity or connection review before the city issues anything if your ADU adds a bathroom. Because short-term rentals aren't allowed, expect the plans examiner to check your site plan for a permanent kitchen setup and ask for an owner-occupancy affidavit tying the ADU to long-term use, which some homeowners don't discover until after they've already drawn up a rental-ready floor plan. Also budget real time for the fire flow and hydrant spacing check on flag lots or homes on well water, since that review isn't listed on the standard fee schedule but routinely adds a week or two before final sign-off.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience working Casselberry permits, that 4-week timeline and the per-sqft cost figure are both state-level estimates rather than verified local numbers, so I'd get a firm quote from a local contractor and call the Building Division directly before penciling in a start date. Even with a clean coastal-free lot, I've routinely seen first-round drawing corrections push a "4-week" review closer to 8-10 weeks in practice. — Charlotte Pemberton, Senior ADU Design Consultant"

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