The short answer

Dundee takes inspection requests by email only, due by 4:00 PM the day before, so a barndominium foundation's pre-pour check gets booked while the termite-treated pad sits covered and waiting. Concrete Barn Slabs Polk County pours it as a monolithic slab with thickened edges, termite treatment, poly and rough-in sleeves, at $10 to $16 per sq ft.

Emailing the Dundee inspection request before the pour

Dundee's Development Services takes every inspection request by email, and the cutoff is 4:00 PM the day before the date you want. The email has to carry the permit number, the job site address, the type of inspection and the requested date. The permit holder sends it, so the pour date rides on that one message.

For a barndominium foundation, the pre-pour inspection comes at the worst possible moment to wait. Your plumber's rough-in is in, the pest control company has treated the soil, and the 6-mil poly is down over it. Rain on treated soil before the poly is placed means retreating it, so we finish poly, steel and sleeves the same afternoon the request goes out, then book concrete for the morning after a pass. If storms are forecast for that window, we hold the treatment back a day rather than gamble. Our barndominium foundation service page covers the method countywide, and the barndominium foundation guide explains the full order of work.

Living on the parcel decides who files in Dundee

Dundee lets homeowners permit work only on homes in which they reside; otherwise the town says to hire a contractor. A new barndo on land you don't live on yet falls on the contractor side of that line, so pick the builder who will hold the permit before you budget the foundation.

The permit holder matters to the slab in two ways. The holder sends the inspection request, so the pour date depends on them. And the Notice of Commencement, which the owner signs, names the contractor when there is one. Florida's lien law calls for a recorded notice on improvements over $2,500 (s. 713.13, read with s. 713.02(5)). The town's form list prints $5,000; a barndominium foundation is past both, so record one either way.

Some town documents were taken down for accessibility updates, and Dundee asks you to contact Development Services for forms and fee sheets. Ask for the Residential Building Permit Submission Checklist on that call, since it tells your designer what the plan set needs.

What It Costs

Our range for a Dundee barndominium foundation, set from the drawings the town approves.

JobPer sq ftTypical projectWhat moves the price
Barndominium monolithic foundation$10 to $16$20,000 to $40,000+Edge depth after corrections, fill, sleeves, truck reach
Monolithic house slab$8 to $15$16,000 to $45,000+Footprint, footing depth, fill

These are ranges, not a quote. You get a free written estimate within 48 hours of the site walk, and we recheck it against the corrected drawings.

Clearing and fill: ask about the Site Work Permit Application

A barndo pad can mean clearing, then bringing in sand to lift the floor. Dundee's form list includes a Site Work Permit Application, so ask Development Services whether your clearing and fill call for it before a dozer shows up.

On the slab side, the rules are set by the Florida Building Code. Under the residential volume, all vegetation and topsoil come out inside the foundation, and fill is capped at 24 inches of clean sand or gravel unless the building official approves more. If your engineer designs under the building volume, compacted fill deeper than 12 inches triggers a geotechnical investigation, and the report sets the density target. We don't quote a compaction percentage the code doesn't give.

Ground changes parcel to parcel around Dundee, so pull your lot on the NRCS Web Soil Survey. USGS places west-central Florida on carbonate rock prone to sinkholes. If you know of a depression or an old filled hole on the lot, tell your engineer, who decides whether a soil boring is worth it.

How the Job Goes

  1. Lot walk and first price

    We walk the Dundee lot and price from the drawing you have.

  2. Approved-set check

    Once the town approves the plans, we compare them with our estimate and update any line that moved.

  3. Pad, rough-in, treatment

    Clearing and fill, then the plumber's rough-in, then the pest control company's treatment and poly.

  4. Inspection by email

    The permit holder emails the request by 4:00 PM the day before, with permit number, address, type and date.

  5. Pour and cure

    We pour after the pass, finish and cure, and tell your framer when to start.

Drawing review and a second look at the slab sheet

The Town of Dundee says its Building Official reviews permit drawings and sends a written correction report, and the town recommends a Florida architect prepare the plans. On a barndo, a correction can reach the foundation: a deeper edge, a thickened band under a bearing wall, or sleeves that move when a bathroom does. We price from the drawing you have, then compare the approved set line by line before pour day and show you anything that changed. Our monolithic house slab page shows how edge depth and bearing bands are built.

Safety inspection, utilities and the fees beside the slab

Dundee's forms list includes a Utilities Application, and Development Services also runs the town's safety inspections for power, which its page ties to sites where power has been off more than 90 days. Ask the office what a new build needs before power goes on. None of it is part of the foundation, but move-in waits on it, so put it on the schedule when you plan the pour.

The town also posts impact and connection fee schedules, including a Transportation Impact Fee Schedule effective January 1, 2025. Those are owner costs that sit outside any concrete quote. Ask Development Services which of them apply to your parcel before you set a total budget, then compare that number with ours.

If the parcel turns out to sit outside town limits, the Polk County Building Division handles the permit instead. The Polk County Property Appraiser lists the Town of Dundee as its own permit agency, so look up the parcel there first.

Dundee barndo slab math at $10 to $16 a foot

Our barndominium foundation range is $10 to $16 per sq ft for a monolithic slab with thickened edges and plumbing and electrical rough-in sleeves. Typical projects run $20,000 to $40,000 and up. A 40 by 56 shell is 2,240 sq ft, so $22,400 to $35,840. What moves a Dundee job inside the range:

  • Edge depth and bearing bands, which plan review can change.
  • Fill to lift the pad, and any geotechnical testing.
  • The number of plumbing and electrical penetrations.
  • Truck and pump reach from the road to the pad.
  • A finished interior floor, which costs more than a plain trowel finish.

Permit, impact and utility fees are separate from our number.

What makes the Dundee site walk go faster

  • The foundation sheet, and the approved set once the town signs off.
  • Your plumber's and electrician's rough-in layout.
  • A survey or site plan with setbacks and easements.
  • Parcel number, so town or county is settled.
  • Who will hold the permit, and the pest control company's name.

Questions We Get

Does Dundee permit the detached garage beside my barndominium too?
Yes. The Town of Dundee requires permits for all accessory buildings and names detached carports, garages, workshops and storage sheds. Ask Development Services whether a garage beside the barndo needs its own permit or can go on the house plans. Tell us at the site walk and we price both slabs together.
Does Dundee need a site work permit to fill a barndominium pad?
Dundee's form list includes a Site Work Permit Application, so ask Development Services whether your clearing and fill call for it. Under the residential code, fill under a slab is capped at 24 inches of clean sand or gravel unless the building official approves more, so a big lift can mean a stem wall.
What does a Dundee inspection request email need?
The town wants the permit number, the job site address, the type of inspection and the date you want, sent by 4:00 PM the day before. The permit holder sends it. For a barndo, we time the termite treatment and poly so the pad isn't left uncovered while that request is pending.
When can power go on at a new Dundee barndominium?
Dundee's forms list includes a Utilities Application, and Development Services handles the town's safety inspections, which its page ties to sites where power has been off more than 90 days. Ask the office what a new build needs before power goes on, and plan it alongside the pour so move-in isn't held up.
Where do I get Dundee's residential permit checklist?
Dundee took some documents off its building page for accessibility updates and asks you to contact the Development Services office for forms and fee sheets. Ask for the Residential Building Permit Submission Checklist and pass it to your designer, since it lists what the plan set has to include.
Should a Dundee barndominium get a soil boring?
Your engineer decides. USGS places west-central Florida on carbonate rock prone to sinkholes, and soil changes parcel to parcel here, so pull the lot on the NRCS Web Soil Survey and mention any depression or filled hole. Compacted fill deeper than 12 inches under the building code calls for a geotechnical investigation.
