Dundee Road first: the town desk that reads your barn drawings
The Town of Dundee runs its own Building Department out of the Development Services Building on Dundee Road, with a Building Official and permit technicians on staff. The Polk County Property Appraiser lists the town as its own permit agency. The town says permits are required for all accessory buildings and names detached carports, garages, workshops and storage sheds. A pole barn slab sits under one of those, so plan on a permit inside town limits.
Parcels outside the town line go to the Polk County Building Division in Bartow. Our Dundee slab contractor page explains how to tell which you have, and our pole barn slab service page covers the floor from pad to cure. Here we stick to what the Dundee desk adds.

Reading a Dundee correction report before it costs you a pour date
The town's permit steps page, written as part of its guide for new businesses, lays out how review works. Once an application and its drawings are accepted, a Dundee Building Official reviews them and sends a written report listing any corrections. When those are made, the permit can issue after a final review. For larger projects, a Building Official will meet with the architect and contractor before the plans go in.
For a barn floor, that report is where slab questions get settled: thickness, steel, post footings, the anchor layout, the pad height. Three habits help:
- Send us the drawing set you submit, and the corrected set when it comes back. We price the corrected one.
- Ask your engineer to answer any slab item on the report in writing, on the sheet, not by phone.
- Don't book a truck or a frame crew off the first set. A changed edge detail or a moved post line changes the forms.
A big equipment barn may justify asking for that pre-submittal meeting. A half hour at the desk can save a full resubmittal.

Owner-builder or contractor: Dundee's residence rule for barns
Dundee's Building Department page says homeowners may permit work only on homes they live in. Otherwise a contractor has to do the work. That line matters for a barn on a second parcel, a pasture down the road or land bought before the house.
If the barn is on the lot you live on, you may be able to pull the permit yourself. If it sits on land where you don't reside, expect to hire a contractor to hold it. The town's permit steps also say to check that every subcontractor is registered with Dundee before work begins, so ask whether your barn erector and your electrician are on file.
Whoever holds the permit books the inspections. We pour to the plans and keep the pad ready on the day they schedule.

How the Job Goes
Read the drawings
We go through your submitted set and any correction report from the town.
Walk the site
We check the gate, the low ground and the post layout on the pad.
Written quote
Within 48 hours, priced to the corrected set.
Pad ready by afternoon
Forms, poly and steel finished so the permit holder can email the request before 4 PM.
Pour after the pass
Concrete goes in once the pad passes; we finish, cut joints and cure the floor.
Emailing a Dundee inspection request by 4 PM the day before
Dundee takes inspection requests by email to the inspections address on its Building Services page. The cut-off is 4:00 PM the day before the inspection you want, and a request that lands after 4:00 PM is scheduled for the next business day. The town asks for four things in the email: the permit number, the job site address, the inspection type and the date you want. An older line higher on the same page still says to call Development Services; the newer notice marked effective immediately is the email rule, so send the email.
For a barn floor, the inspection that matters to us is the one before concrete. We finish the pad, forms, any termite treatment and poly, and the steel, then the permit holder sends the request that afternoon. We order the truck once the pad passes. If a storm rolls through after the poly is down, we check the pad again before the inspector sees it. Rain on freshly treated soil before the poly is down means the treatment gets redone.
Keep the permit number handy from the day it issues. A request without it isn't complete, and a missing slot costs a day.
Farm barns, the town's exemption request and a power hookup
A working farm barn on agricultural land may qualify for Florida's s. 604.50 exemption from the building code. Our farm building exemption guide covers the test, the floodplain carve-out and why a home never qualifies. In Dundee, the form to use is the Building Permit Exemption Request in the town's download list. Get the answer in writing before you skip a permit.
Power is the next question. The town lists safety inspections as needed for utilities to be turned on, so a barn with lights and outlets should expect an inspector even if the building itself is exempt. Plan conduit runs before the pour: each sleeve that comes up through the floor is set in the forms, not cut in later.
Thinking about a bedroom or bath in the barn? Then it's a house, and our Dundee barndominium foundation page covers that slab.
Slab details a Dundee barn drawing should already show
- Thickness: our barn floors run 4 to 6 inches; the residential code floor is 3-1/2 inches, and heavy equipment goes on the engineer's sheet.
- Crack control: fiber, or 6x6 welded wire in the middle to upper third, or contraction joints about 10 feet apart on a 4 inch floor per NRMCA.
- Post plan: posts set before or after the floor, with any footings or collars drawn. Our posts first or slab first guide compares the two.
- Anchors: bolt or bracket layout matched to the supplier's frame drawing.
- Pad: fill depth and pad height, with your parcel's soil read from the NRCS Web Soil Survey.
- Sleeves: every conduit and water line through the slab.
- Door edges: thickened where tractors and trailers roll in.
Dundee barn floor prices by size
Our pole barn slab range is $7 to $12 per sq ft, with a typical 30x40 project at $8,500 to $15,000. By footprint:
- 24x30 run-in or small storage barn, 720 sq ft: $5,040 to $8,640.
- 30x40 barn, 1,200 sq ft: $8,400 to $14,400.
- 40x60 equipment barn, 2,400 sq ft: $16,800 to $28,800.
Every one of those is over $2,500, the line where Florida's lien law calls for a recorded Notice of Commencement (s. 713.13, read with s. 713.02(5)). The form is in Dundee's download list, so build it into the schedule. Inside the range, the floor moves on fill, thickness, post work, truck access and sleeves. Our pole barn slab cost guide covers each. Pours here follow the rainy season, May 25 to October 10, so summer work starts early. Your price comes in a free written estimate after we see the site.
