Inspection Types

Listed Below are the inspection types outlined by the Wisconsin Uniform Dwelling Code.

The following is an excerpt from the UDC commentary regarding inspection types:

Depending on the number of inspectors involved, coordination of the trades and the type of construction, the number of separate inspections could vary from four to eleven. There maybe additional inspections necessary due to callbacks regarding incomplete work or non-complying conditions.

Prior to performing any inspections, it would be a good policy to review the approved plans. Particular notice should be given to any deviations or unusual conditions that may exist.

Footing and Foundation Inspections

Depending on the type of footings and foundation, the number and timing of inspections varies as follows:

  • Unreinforced concrete footings - Inspected before pouring of concrete.

  • Reinforced concrete footings - Inspected after placement of forms and reinforcing and prior to pouring of concrete.

  • Masonry or unreinforced concrete foundation - Inspected after placement of materials.

  • Reinforced concrete foundation - Inspected after placement of forms and reinforcement and prior to pouring of concrete.

  • Wood Foundations - Inspected after framing and sheathing and prior to the placement of gravel.

  • Foundation drain tiles, waterproofing and exterior insulation (when required) - Inspected prior to soil backfill. This may be combined with the inspection of masonry or unreinforeed concrete foundations. The interior drain tiles and any under slab plumbing, electrical or heating work shall also be inspected prior to the pouring of the basement floor.

Zoning setbacks are also commonly verified at the time of footing inspection.

Rough Inspection

The important principle to remember is that all work must be inspected prior to concealment. It is possible that all of the construction trades are coordinated enough so that all the rough-in inspections can be accomplished during one inspection. However, it is unlikely that the insulation inspection can be done at the same time because the insulation normally conceals the other work. Also, the rough framing inspection is best done after the electrical and heating work is done so that notching and boring can be checked.

Occasionally, a contractor will not properly call for an inspection so that the inspector does not have the opportunity to verify compliance prior to concealment of some work.

Possible options that the municipality may consider are:

  • Removal of all covering work so a full inspection can be made

  • Removal of representative section(s) of covering work as chosen by the inspector, alternative testing of materials

  • Affidavits by witnesses verifying the original work, or
  • Noting of the permanent file, and possibly on the property deed, that compliance of certain items was not verified

Selection of the option(s) is at the discretion of the municipality and should be done in consultation with the municipal legal counsel.

Rough Electrical

Section 101.865 of the Wisconsin Statutes requires that the utility furnishing the electrical current obtain proof that the wiring complies with these standards before furnishing the current. Proof must be a certificate furnished by the inspection department which may be the certified independent inspection agency or the municipality administering and enforcing this code. The electrical utilities will require a certificate of inspection prior to energizing the electrical services, be they temporary or permanent installations. If there is no certified agency or municipality, proof consists of an affidavit furnished by the contractor or other person doing the wiring.

Rough Plumbing Inspections

There may be separate required inspections for the sewer and water laterals, underslab plumbing and the rest of the rough plumbing.

Inside Drain Tile Inspection

This section requires any required inside drain tile and related underslab aggregate to be inspected. It does not require the underslab vapor barrier to be inspected prior to pour.


Generally, the insulation and vapor barrier are installed after all other rough inspections have been made so as to avoid displacement of the insulation by the heating, electrical or plumbing systems.

Final Inspection - Inspector Certification

A final inspection prior to occupancy requires inspections of the construction, HVAC, electrical and plumbing systems by an inspector or inspectors certified in all of those categories.

Final Inspection - Health and Safety Items

Special attention should be given the words "health and safety" in this section. It is clearly not the intent of the Uniform Dwelling Code to prevent persons from moving into their homes where certain cosmetic items have not been completed. For example, unpainted rooms, uncompleted trim work, lack of carpeting, etc., would not prevent occupancy.

On the other hand, incomplete exiting arrangements, open electrical boxes, missing handrails and guardrails, open plumbing drains, etc., could constitute items affecting health and safety and would prevent occupancy.

Basic plumbing requirements for personal hygiene and culinary purposes that must be installed in the dwelling are a stool, wash basin, tub or shower, kitchen sink and hot water. All must be fastened in place and must be functional This means water service and drain, waste and vent piping must be provided and operational. The wash basin, kitchen sink, tub or shower must have hot water connections and all unused sewer connections must be sealed.
