START OF CONSTRUCTION
Includes substantial improvement and other proposed new development
and means the date the permit was issued, provided the actual start
of construction, repair, reconstruction, rehabilitation, addition,
placement, or other improvement was within 180 days from the date
of the permit. The actual start means either the first placement of
permanent construction of a structure on a site, such as the pouring
of slab or footings, the installation of piles, the construction of
columns, or any work beyond the stage of excavation; or the placement
of a manufacture home on a foundation. Permanent construction does
not include land preparation, such as clearing, grading, and filling;
nor does it include the installation of streets and/or walkways; nor
does it include excavation for a basement, footings, piers, or foundations
or the erection of temporary forms; nor does it include the installation
on the property of accessory buildings, such as garages or sheds not

a substantial improvement, the actual start of construction means
the first alteration of any wall, ceiling, floor, or other structural

or lot development; provided, however, that the subdivision by lease
of land for agricultural purposes into parcels of more than 10 acres,
not involving any new street or easement of access or any residential
dwelling, shall be exempted.
SUBSTANTIAL DAMAGE
Damage from any cause sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would
equal or exceed 50% or more of the market value of the structure before
the damage occurred.
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceeds 50% of the market
value of the structure before the start of construction of the improvement.
This term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
A.
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions;
or
B.
Any alteration of a historic structure, provided that the alteration
will not preclude the structure's continued designation as a
historic structure.
UNIFORM CONSTRUCTION CODE (UCC)
The statewide building code adopted by The Pennsylvania General
Assembly in 1999 applicable to new construction in all municipalities,
whether administered by the municipality, a third party or the Department
of Labor and Industry. Applicable to residential and commercial buildings,
the code adopted the International Residential Code (IRC) and the
International Building Code (IBC), by reference, as the construction
standard applicable with the state floodplain construction. For coordination
purposes, references to the above are made specifically to various
sections of the IRC and the IBC.
