Permits, Licenses + Inspections for Building + Construction

Accessory Structures

A permit is not required for accessory structures such as garages, sheds, carports or gazebos fewer than 200 square feet in area.

Air Conditioner Repairs

Air conditioner repairs do not require a permit. If the demand for the unit is greater than the old unit, conductor sizes may need to be increased. A means to disconnect power is required within sight of the unit. A permit is required for new, additional, or replacement furnaces or air conditioning systems.

Arbors, Trellises + Shade Structures

A permit is not required when the overhead structure is at least 50 percent open at the top with no member wider than 2 inches in horizontal plane and incapable of accumulating ice or snow. Structures must comply with setback requirements and maintain clearances to service-drop conductors.

Awnings + Canopies

A permit is not required provided the awning does not project more than 54 inches from the exterior wall.

Basketball Goals

A permit is not required. Structures greater than 10 feet in height must be located a distance from the property line equal to one-third the height of the structure.

Roofing + Re-Roofing

A permit is not required. The code has specific material and installation requirements for roofing and re-roofing. A composition roof may be installed over wood shingles, not over shakes. No more than two layers of any type of covering may be placed on a roof. If three layers of roofing are in place, all layers must be removed prior to installation of additional roofing. Some homes associations regulate the quality and color of roof coverings.

Re-roofing is considered a repair and may not require a permit, unless you are switching from a light roof covering like asphalt or wood shingles to a heavy roof covering like concrete tiles, clay tiles, or slate. Changing from a light roof covering to a heavy roof covering requires a permit and an engineered analysis of the roof structure and usually requires additional reinforcement of the roof.

Although a permit is not required, the code has specific material and installation requirements for roofing and re-roofing which must be followed by the person or persons undertaking the repair or replacement. (2018 IRC Section R908)

A composition roof may be installed over wood shingles (not permitted over wood shakes) if the shingle manufacturer allows it. No more than two layers of any type of covering may be placed on a roof. If two or more layers of roofing are in place, all layers must be removed prior to installation of additional roofing. Roof decking shall be inspected by the roofer and any necessary repairs should be made. The City will not inspect this type of project.

Check with your homes association for regulations of roof coverings as these are not enforced by the city.

Adding an additional layer of roof covering is not permitted in the following conditions:

1. Where existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing.
2. Where the existing roof covering is slate, clay. Cement or asbestos-cement tile.
3. Where the existing roof has two or more applications of any type of roofing covering.

Ice Barriers

An ice barrier is required. Please reference 2018 IRC Section R905.1.2 and OPMC 16.110.R301.2(1). Ice barriers shall be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes. The ice barrier shall consist of not fewer than two layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet shall be used in place of normal underlayment and extend from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building. On roofs with slope equal to or greater than eight units vertical in 12 units horizontal (67%slope), the ice barrier shall also be applied not less than 36 inches (914 mm) measured along the roof slope from the eave edge of the building.

An ice barrier is not required for detached accessory structures not containing conditioned floor area.

Materials

Only Class A, B or C roof covering materials are allowed. Non-classified roofing is not allowed. All roof covering materials shall be delivered in packages bearing the manufacturer’s identifying marks and approved testing agency labels.

Structural + Construction Loads

The structural roof components shall be capable of supporting the roof covering system, and the material and equipment loads that will be encountered during installation of the roof covering system.

Roof Covering

Where the application of a new roof covering over wood shingle roofs creates a combustible, concealed space, the entire existing surface shall be covered with gypsum board, mineral fiber, glass fiber or other approved materials securely fastened in place.

Reinstallation of Materials

Existing slate, clay, or cement tile shall be permitted for reinstallation, except damaged, cracked, or broken slate or tile which shall not be reinstalled. Existing vent flashing, metal edgings, drain outlets, collars and metal counter flashing shall not be reinstalled where rusted, damaged or deteriorated. Aggregate surfacing
materials shall not be reinstalled.

Flashings

Flashings shall be reconstructed in accordance with approved manufacturer’s installation instruction. Metal flashings, to which bituminous materials are to be adhered, shall be primed prior to installation.

Roof Deck – Repair/Replacement

A permit is not required unless structural repairs are necessary.

Floodplain Development Permits

Re-roofing a structure shall be considered routine maintenance and exempt from requiring a floodplain development permit except in the following cases:

The sheathing or joists underneath the roofing materials are replaced or other structural repairs are necessary.

The roofing is replaced in conjunction with other building repairs that require a building permit. For example, storm damage to the roof that damages other portions of the structure.

If a floodplain development permit is required, information about the cost of all repairs shall be provided to verify that the repairs do not constitute a substantial improvement to the building.

Satellite Dishes

A permit is not required. Dishes 39 inches in diameter or smaller may be attached to the house. Ground-mounted dishes must be in the backyard and set back from the property line by a distance equal to its height.

Sewer

Johnson County permits repair and replacement sewer lines outside of a building that are connected to the Johnson County Wastewater sewer system.

Sidewalks

The City maintains sidewalks on public streets. Please file an OPCares request if your sidewalk needs maintenance.

Siding

Siding repair and replacement are considered maintenance and do not require of a permit, except when replacing with stucco or EIFS. These materials require a permit.  The building code contains requirements regarding siding applications and flashing.
