Who handles permitting in Polk County?

Building Inspections enforces the construction, plumbing, electrical and mechanical codes throughout the county. Patrick Rimer is the Building Inspections Director. Environmental Health and Planning share the same Community Development offices, so septic, zoning and address requests are filed on the same form as the building permit.

The combined application and other forms

The Polk County Building/Environmental Health/Zoning/911 Application (March 2025 fill-in version) collects everything for a new site on one form: the structure, the septic and well request, the zoning details and the new address, plus every licensed contractor, the lien agent and a site plan. Changing a licensed contractor without updating the application is grounds for revoking the permit. A driveway must already be cut in before a new 911 address is assigned.

The Inspections documents page also has the residential, commercial, mobile home and miscellaneous permit applications, the Owner/Builder Licensing Exemption, the Workers’ Compensation form and a Change of Contractor form. Issued permits can be looked up with the County’s online building permit search.

The general contractor’s licence qualifier must apply for and pick up the permit, unless they sign a notarized statement naming an agent for that job; owner-builders file the notarized licensing exemption form.

Polk County building permit fees

The fee schedule the County posts is dated July 21, 2020, and it lists the permits issued most often.

A new house with 2,000 heated sq ft is $640 on this schedule, plus the $10 recovery fee when a general contractor builds it. Attached garages, porches, decks, fireplaces, retaining walls and elevators are charged on top. Fees cannot be refunded once 30 days have passed since the permit was issued.

What to have ready

The County’s residential permit guide lists these in order of importance:

• Septic and well layout from Environmental Health. For its evaluation, property lines and the proposed building must be staked and flagged.
• Zoning approval: from Town Hall in Columbus, Tryon (including its ETJ) or Saluda, or the County zoning permit outside town limits, with a plat or drawing of the property lines and existing and proposed buildings.
• A 911 address.
• One set of plans: elevations of every side, foundation plan, floor plan, wall section, and roof framing and ceiling joist plan or engineered truss drawings. Modular plans need the State of North Carolina approval stamp on every page and the right foundation plan.
• Contractor details: the subcontractors’ names and licence numbers as they appear on their licences.
• Tax card and flood information where relevant; in a mapped special flood hazard area, the design must also meet the County’s Flood Damage Prevention Ordinance.

Leave the plans with the inspection office for approval, which can take a couple of days. They come back to you, and the approved set must stay on the job site.

Call for each inspection at least 24 hours ahead, with the permit number, and have the permit and approved plans on site along with toilet facilities. Owner-builders call in the inspections for all work they are listed for on the application.

No inspection is made until a Code Enforcement Official has checked the setbacks. The County’s list for a house then runs through footings, the temporary service pole, underground plumbing with a test, water and sewer lines, foundation drainage and wall sealant, foundation walls or piers, the floor system, slab preparation, fireplace and chimney, heater flues, retaining wall and deck footings, the garage slab, all rough-ins with plumbing and gas tests, insulation, and the building, electrical, plumbing and mechanical finals. Extra trips because the job was not ready, had violations or was locked can carry additional fees.
