INFORMATION ON BUILDING DETACHED GARAGES AND ACCESSORY BUILDINGS TO RESIDENTIAL PROPERTIES ZONED “R-3” (SINGLE FAMILY, MIN.LOT 11,000 SQ FT.)

Attached Garage: 

A Building Permit is required to construct an attached garage. Attached garages must be setback 30 feet from the front and rear property lines. The side setback shall be five feet from the side property line. If adjacent to a public street (corner lot), the side setback shall be 20 feet from the side property line. Note: In most cases the front property line is located 13 feet from the curb. The maximum size of an attached garage is limited by the size of the dwelling. Plans may be referred to the Planning Department for determination of maximum size. Note: Frost depth footings and foundations are required on all structures attached to the principle structure.

An attached garage wall shall be separated from the residence and its attic area by not less than 1/2” gypsum board applied to garage side. Horizontal framing members 16” on center require 5/8” type x drywall. 

Detached Garage: 

A detached garage (intended for parking vehicles) is considered an accessory building. Requirements and restrictions are the same as for an accessory building of the same size; see requirements below. A concrete or asphalt driveway is required for all garages.

Accessory Building: 

An accessory building is any structure not attached to the principle structure on a lot. The maximum height for all accessory buildings is 16 feet, measured from the finished grade around the building to the peak of the roof. All Accessory buildings shall be suitably anchored to the ground. The structure must be bolted to a concrete slab or secured with approved ground anchors. Accessory buildings shall not be located in the front yard or in a public drainage or utility easement.

Accessory Building: 200 square feet or less 

A building permit is not required for detached structures (sheds) that are 200 square feet or less in floor area and no more than one story in height. Small sheds (120 SF or less) must be located in the side or rear yard areas a minimum of 5 feet from the side and rear property lines or 10 feet from the rear property line if you have a 10 foot easement. On corner lots, adjacent to a public street, the setback must be 20 feet from the side property line. 

Accessory Building: OVER 200 square feet 

A building permit is required for all detached structures over 200 square feet. A building permit application, legal survey and building plans shall be submitted to the City. All accessory buildings exceeding 120 square feet in area shall be setback a minimum of 30 feet from the front property line, 5 feet from a side property line (20 feet on corner lots) and 10 feet from the rear lot line. Accessory buildings should be set back 5 feet from the house, less than 5 feet can be approved if appropriate fire protection is provided. Contact a Building Inspector for the specific details. The maximum size for all detached structures is 750 square feet of floor area and the maximum height is 16 feet.

Gazebo:

If a gazebo is being attached to a porch or deck that is attached to a house, it is not considered an accessory building. If the gazebo is larger than 120 SF, one other accessory building less than 120 SF is allowed. If the gazebo is less than 120 SF in size, one other accessory building larger than 120 SF will be acceptable.

Maximum number of Accessory Buildings:

Only two accessory structures are allowed on each lot. One structure shall not exceed 750 square feet of floor area and the second one shall not exceed 120 square feet.

Natural Resources Management Permit (NRMP):

If any excavation is done, the Natural Resources Department will determine if a NRMP is required. A NRMP Permit Application must also be completed for each project. 

Setback Requirements:

Residential properties located in “PD” (Planned Development) or other “R” zoning district may have different setback requirements that require Community Development Department determination. 


INSTALLING HEAT IN A GARAGE OR SHED


Permits:

If you are adding a furnace or heating appliance, you need to obtain a mechanical permit. All appliances shall be listed and tested by a third party agency and installed per manufacturer’s installation instructions.

If adding insulation in walls or ceiling, you will need to obtain a building permit in addition to the mechanical permit.

An electrical permit may also be needed. To apply for all of these permits, please go to the City of Apple Valley’s online permitting website.

Insulation:

Garages and sheds are exempt from the requirements of the energy code.  The building code requires that a vapor barrier be installed on the warm side of fiberglass insulation. Vapor barriers shall be covered or shall be of flame retardant materials.

Attic Insulation:

Roof vents and exterior soffit vents are required to ventilate the attic space. If the ceiling is insulated, air chutes are required between the rafters at the exterior walls to provide an air space between the ceiling insulation and the roof plywood.

Attic Access:

A 22 by 30 attic access shall be provided if the attic area is 30 square feet or more and has a vertical height of 30 inches of more.

Mechanical:

If the walls and ceiling are insulated, proper combustion air shall be provided for all fuel burning appliances.

The flue pipe shall have the proper clearance to combustibles for the entire length. A metal sleeve shall be provided where the vent passes through attic or wall insulation. The sleeve shall provide a one inch clearance from the insulation to the flue pipe.

An approved (UL listed) cap is required on the vent termination.

Gas Lines:

All gas lines shall be tested with air pressure. The test shall be a minimum of 25 psi for 30 minutes and the city inspector shall witness the test.

Inspections:

Attic ventilation, attic access, ductwork, venting and gas lines must be inspected before covering. Call the Inspections Department at 952-953-2588 to arrange inspections.
