. While every
attempt has been made to insure the correctness of this handout, no guarantees are
made to its accuracy or completeness. Responsibility for compliance with applicable codes and ordinances falls on the owner or contractor.
For specific questions regarding code requirements, refer to the applicable codes or contact your local Building Department.
Building Permits Requirements:
Building permits are required for the
construction of all decks that are
attached to the home and for freestanding
decks that are 200 Sq Ft or more in area
and elevated 30” or more above grade.
Deck construction shall
meet the requirements of the 2013
Kentucky Building Code which
adopts and amends the 2012
International Residential Code.
Zoning Requirements:
Decks are also required to meet the
land use and setback requirements of
the zoning code.
Plan Review & Inspections:
The plan is reviewed by the plans
examiner in order to identify potential
problems that may arise prior to
construction. Construction inspections
will be done during the project to ensure
code compliance and that the materials
used are installed correctly.
30” or more
above grade

Builders and homeowners are required to obtain a permit prior to
constructing, altering or replacing a deck.
The following are examples of inform
ation that should be included on
plans submitted for building permits for residential decks. They are
examples only and should not be construed as being code compliant for
every application. It is the responsibility of the homeowner or person
preparing the plans to show in detail how they will build their deck.
Some designs may require more detail than others.
Your deck plans should replicate exactly how you will build your deck.
We will review your plans before we issue the building permit to verify
code compliance before you start work. The more detailed your plans,
the more likely you will avoid mistakes during construction.
Once your plans are approved, you should not change your design
without approval by LFUCG Building Inspection Division. You should
read through the approved plans to determine if the plan reviewer
noted any corrections to your plan. If you have any questions
regarding any of the corrections you should contact us before
proceeding.
Permit holder is responsible for scheduling all inspections.
Plans created at home centers are seldom acceptable for plan review.
These computer designs do not al
low homeowners to duplicate actual
conditions at their home. Some of these plans may be modified to
include all necessary information prior to submittal. Applications
submitted with these types of plans without additional modifications will
be returned to the applicant.
THINK YOU MIGHT ENCLOSE YOUR DECK IN THE FUTURE?
Deck plans are approved on the assumption that the deck will be used
only as a deck for the life of the structure. Because footing sizes,
setbacks, structural supports and a host of other deck components are
different for enclosed porches than for decks. It is important that you
indicate on you plans the desire to convert the deck at a future date.
You should then design your deck to carry future loads and meet
setbacks and other rules

Post footings supporting columns larger than 4x6 must be not less than 8-

desired minimum bearing area. The base of the footing must be at least 42
inches below finished grade. Care should be exercised to center the
column on the footing. Posts imbedded in the ground must be labeled
ground contact or equal. The use of a fiberboard tube will allow you to
elevate the top of the footing above finished grade to provide protection of
the wood post from lawn mowers and trimmers.

RAILINGS
Guardrails are required for portions of decks 30” or more above grade. The height of the rail must be a
minimum of 36”. Open guardrails must have intermediate rails or an ornamental pattern that a 4” sphere
cannot pass through. Guardrails must continue down stairs where the stair is more than 30 inches above
grade.
STAIRS
Stairs must have a maximum rise of 8 1/4 inches and a minimum run of 9 inches. The run is measured
from the nosing of one tread to the nosing of the next. The greatest riser height within any flight of stairs shall
not exceed the smallest by more than ⅜ inch. The greatest tread depth within any flight of stairs shall not
exceed the smallest by more than ⅜ inch.
Maximum step down is 8 ¼” from interior finish
ed floor to top of the deck platform at the patio door.
Open risers are permitted provided that a 4” diameter sphere will not pass thru the opening between the
treads.
SAFTEY GLAZING
All glass (windows) shall be reviewed for tempered glazing requirements. Be sure to show location of
all windows in relation to deck stairs, landings, top and bottom treads, and walking surfaces.
Wood Treatment
Wood used above ground, in contact with the ground, or below ground requires different degrees of treatment.
Check the labels of the material you are buying to determine where it can be used. Because the new
preservative treatments are very corrosive, make sure that any metal connectors used in the
construction of your deck are approved by the manufacturer for use with treated wood.
Decking
Materials commonly used for decking include standard dimension lumber (either 2X4 or 2X6), radius-edged
decking, or a manufactured decking product. 2X6 dimension lumber is the only lumber product that can
be used on joist spacing of 24 inches.
Radius-edged Patio Decking has been specifically developed for outdoor decks. Patio decking is intended to
be used flat-wise in load-bearing applications where joist spacing does not exceed 16" o.c. (12” o.c.
when installed diagonally to joists).
Manufactured decking products may be used only when approved by the Building Department. This
approval is based on the material carrying an NER research report. Decking without a research report will not
be approved. Ask the decking supplier to provide you with a copy of the research report. The Building
Department maintains a list of decking materials that have been approved for use in Minnesota that is available
upon request. Caution – some manufactured deck products are approved for decking but not for stair
treads. In some cases where manufactured decking is approved for stairs, the spacing of supports
Electrical service lines over
or within 3' horizontally of
the deck or stairs must have
a minimum 10' vertical
clearance.

may be significantly reduced compared to use on the deck itself. Read the research report for further
information.

INSPECTIONS
The Building Department will typically make at least two inspections of your deck. It is your responsibility
to call for an inspection 1-2 days in advance of the time you need an inspection. When you call for an
inspection, you will be asked for your address, the type of inspection you desire (footing, framing, final),
the permit number (which is found on your building permit), and the time you want the inspection. We will
make every effort to accommodate requests for inspections at specific times.
Permit holder is responsible for scheduling all inspections.
The first inspection will be of the post footings. At the time of the inspection, property pins shall be
exposed, the holes should be dug and all loose material should be removed but no concrete should be
poured. The inspector will check the depth of the footing and it’s width at the base. They shall also check
the location of the footings for compliance with the zoning ordinance. If you are having problems with
water seeping into the hole, you may wish to insert a large plastic garbage bag into the hole and pour the
concrete into the bag to displace water without compromising the concrete.
The next inspection is the framing and final inspection. The inspector will check the size and spacing of
joists, beams and columns, the attachment to the dwelling including flashing, the type of fasteners and
lumber being used, type of decking used, railings, stairs, and landings. If your deck will be built such that
the underside of the deck will not be visible or accessible at the final inspection, or you wish to have a
framing inspection done prior to installation of decking and rails, please call for that inspection.
If a violation is detected a notice will be prominently placed on the digital record with the correction that
must be made and time limit allowed for corrections. The notice will also indicate if a re-inspection will be
necessary. If a re-inspection is necessary you must call for the inspection and have the correction
approved before proceeding unless directed otherwise by the inspector.
If at any time during the construction of your deck you have a question, please do not hesitate to call the
Building Department at (859) 258-3770.
