new fees.The building official may approve further modification to the three-year
expiration date due to hardship,such as,death,serious health problems,foreclosure,
bankruptcy,or involuntary property transfer imposed by law.The permittee shall submit

no change in the existing occupancy classification of a building or structure or portion
thereof shall be made until the building official has issued a certificate of occupancy
therefore as provided herein.Issuance of a certificate of occupancy shall not be
construed as an approval of a violation of the provisions of this code or of other
ordinances of the jurisdiction.Certificates presuming to give authority to violate or
cancel the provisions of this code or other ordinances of the jurisdiction shall not be
valid.
Exception:Certificates of occupancy are not required for work exempt from permits

follows:
Combustible —a material that fails to meet the acceptance criteria of the Standard
Method of test for determination of non-combustibility in building materials.
Combustible construction —a type of construction that does not meet the requirement
for noncombustible construction.
Defensible space —a natural or man-made area,where woody vegetation capable of
allowing a fire to spread unchecked has been treated or modified to slow the spread
and reduce the intensity of an advancing wildfire,and to create an area for fire
suppression operations to occur.
Fire-resistive construction —construction designed to resist the spread of fire.
Fire-resistive rating —is the time that the material or construction will withstand the
standard fire exposure as determined by a fire test made in conformity with the
standard methods of fire tests of buildings construction and materials.
Fire-retardant-treated wood —any wood product impregnated with chemicals by a
pressure process or other means during manufacture,and which shall have a flame-
spread index of not over 25.
Fire separation —a construction assembly that acts as a barrier against the spread of
fire.
Firewall assembly —a type of fire separation of noncombustible construction which
subdivides a building or separates adjoining buildings to resist the spread of fire and
which has a fire-resistance rating and structural ability to remain intact under conditions
for the required fire-rated time.
Flame-resistant material —material that has been modified in its chemical composition
by impregnation,coating or has inherent composition that makes the material resistant
to ignition and combustion when exposed to a small ignition source.
17
0 0
Flame retardant —is an approved chemical compound or mixture which,when applied
in an approved manner to any fabric or other material will render such fabric or material
incapable of supporting combustion.
Flame-spread index (FSI)—a relative index describing the surface-burning
characteristics of building materials.The test used to establish FSI evaluates the flame
spread over the building material surface when exposed to a test fire.The rate at which
flame spreads across the specimen is compared on a scale of 0 for inorganic reinforced

is attained by the use of noncombustible materials for structural members and other
building assemblies.
One-hour Fire-resistive Construction —will withstand the standard fire exposure”for
one-hour “as determined by a fire test made in conformity with the standard methods of
fire tests of building construction and materials.”
Slash —unusual concentrations of downed fuel resulting from such natural events as
wind,fire,or snow breakage or such human activities as timber harvesting,road
construction,or building construction.
Wildfire Hazard —the relative likelihood that a fire,once started,will become
disastrous.Disastrous means the destruction of life and improved property.

101.1 Title.These regulations shall be known as the Plumbing Code of the Town of
Estes Park hereinafter referred to as “this code.”
101.3 Intent.The purpose of this code is to provide minimum standards to safeguard
life or limb,health,property and public welfare by regulating and controlling the design,
construction,installation,quality of materials,location,operation and maintenance or
use of plumbing equipment and systems.The intent of this code is to meet or exceed
the requirements of the State of Colorado Plumbing Code.When technical
requirements,specifications or standards in the State Plumbing Code conflict,the more
restrictive shall apply.Specifically,the State Plumbing Code shall apply in those
instances where this does not provide technical requirements,specifications or
standards.This shall apply in those instances where the State Plumbing Code does not
provide technical requirements,specifications or standards.Should the State Plumbing
Code and this code each provide technical requirements,specifications or standards on
any single matter in terms so distinct that determining which is more restrictive is not
readily apparent,the State Plumbing Code shall apply.
103.1 General.The department of building safety is hereby created and the executive
official in charge thereof shall be known as the building official hereinafter referred to as
the code official.
103.2 Appointment.The Director of Community Development shall appoint the code
