"101.2 Scope. Except as otherwise specified, the provisions of this code shall apply to all existing residential and nonresidential structures and all existing premises and constitute minimum requirements and standards for premises, structures, equipment and facilities for light, ventilation, space, heating, sanitation, protection from the elements, life safety, safety from fire and other hazards, and for safe and sanitary maintenance; the responsibility of owners, operators and occupants; the occupancy of existing structures and premises, and for administration, enforcement and penalties."

(2) Sections 102.2, 102.3 and 102.5 are hereby amended to read as follows:

"102.2 Maintenance. Equipment, systems, devices and safeguards required by this code or a previous regulation or code under which the structure or premises was constructed, altered or repaired shall be maintained in sound working condition. No owner, operator or occupant shall cause any service, facility, equipment or utility which is required under this section to be removed from or shut off from or discontinued for any occupied dwelling, except for such temporary interruption as necessary while repairs or alterations are in progress.

In the performance of said duties, such official may delegate authority to the appropriate technical, administrative, and compliance staff under the supervision of said official as he or she deems necessary. The code official is hereby authorized to, and shall, enforce the provisions of this code.

"104.2 Rule-making authority. The code official shall have authority as necessary in the interest of public health, safety and general welfare, to adopt and promulgate rules and procedures; to interpret and implement the provisions of this code; to secure the intent thereof; to enforce all provisions of this Code pursuant to the authority granted by the Chief of Police and specified in City Code Section 2-503(b)(2); and to designate requirements applicable because of local climatic or other conditions. Such rules shall not have the effect of waiving structural or fire performance requirements specifically provided for in this code, or of violating accepted engineering methods involving public safety.

"104.3 Inspections. The code official shall make all of the required inspections, or shall accept reports of inspection by approved agencies or individuals. All reports of such inspections shall be in writing and be certified by a responsible officer of such approved agency or by the responsible individual. The code official is authorized to engage such expert opinion as deemed necessary to report upon unusual technical issues that arise, subject to the approval of the appointing authority. Whenever necessary to make an inspection to enforce any of the provisions of this code or any other section of the City Code or Land Use Code or whenever the code official has probable cause to believe that there exists in any building or upon any premises any condition or violation which makes such building or premises substandard, dangerous, unfit for occupancy or unlawful, the code official may enter such building or premises at all reasonable times to inspect it or to perform any duty imposed upon the code official by this code. If such building or premises is occupied, the code official shall present proper credentials and request entry. If such building or premises is unoccupied, the code official shall first make a reasonable effort to locate the owner or other persons having charge or control of the building or premises and request entry. If such entry is refused, or, if after reasonable efforts to contact the owner or occupant, the owner or occupant cannot be found or fails to respond or consent to the request, the code official may seek an inspection warrant from the Municipal Judge to secure entry for inspection or abatement.

"104.4 Right of entry. When the code official has obtained a warrant or other remedy provided by law to secure entry, no owner or occupant or any other persons having charge, care or control of any building or premises shall fail or neglect, after proper request is made as herein provided, to promptly permit entry therein by the code official for the purpose of inspection, examination or abatement pursuant to this code. Any such failure to permit entry upon request pursuant to a valid inspection warrant shall be a misdemeanor punishable by the provisions set forth in City Code Section 1-15."

(5) Section 105.4 is hereby amended to read as follows:

"105.4 Material and equipment reuse. Materials, equipment and devices shall not be reused unless such elements are in sound condition or have been reconditioned and tested when necessary, placed in sound working condition and approved."

(6) Sections 106.3 and 106.4 are amended to read as follows:

"106.3 Prosecution of violation. Any person failing to comply with a notice of violation or order served in accordance with Section 107 shall be deemed guilty of a misdemeanor or civil infraction as determined in Section 106.4, and the violation shall be deemed a strict liability offense. If the notice of violation is not complied with, the code official shall institute the appropriate proceeding at law or in equity to restrain, correct or abate such violation, or to require the removal or termination of the unlawful occupancy of the structure in violation of the provisions of this code or of the order or direction made pursuant thereto. Any action taken by the authority having jurisdiction on such premises shall be charged against the real estate upon which the structure is located and shall be a lien upon such real estate.

"106.4 Violation penalties. Any person who violates Section 108.1.5, or any notices or orders issued for a violation of Section 108.1.5, 108.4.1, 108.5 or any provision of Section 109 commits a misdemeanor and is subject to a fine, imprisonment, costs and fees and any other orders imposed in accordance with City Code Section 1-15. Any person who violates any other provision of this Code commits a civil infraction and is subject to the penalty provisions of City Code Section 1-15(f). In addition, the code official may revoke or suspend any permit or certificate issued by the City with respect to the building, structure, premises or equipment."

(7) Section 107 is hereby amended by the addition of a new Section 107.1.1 to read as follows:

"107.1.1 Responsibilities and obligations. Every owner and occupant shall be subject to the responsibilities and obligations set forth in this code as follows:

"1. Every owner remains liable for violations of duties imposed by this code even though an obligation is imposed on the occupants of the building and even though the owner has by agreement imposed on the occupant or property manager the duty of furnishing required equipment or of complying with this code. Nothing herein shall be construed as limiting or interfering with in any way the right of any persons to establish by written contract specific responsibilities of owners, property managers and occupants for the purpose of leasing or renting a building or premises. Every owner or agent, in addition to being responsible for maintaining the building in a sound structural condition, shall be responsible for keeping that part of the building or premises which the owner occupies or controls in a safe condition, including the shared or public areas in a building containing two (2) or more dwelling units.

"2. An owner shall not permit another person to occupy premises which are not in a sanitary and safe condition and which do not comply with the requirements of this code.

"3. Occupants of a dwelling unit, rooming unit or housekeeping unit are responsible for keeping in a clean, sanitary and safe condition that part of the dwelling unit, rooming unit, housekeeping unit or premises which they occupy and control.

"4. Every occupant shall, when required by this code, the City Code or the Health Officer, furnish and maintain approved devices, equipment or facilities necessary to keep the premises safe and sanitary.

"An owner of a building or premises remains liable for violations of this code even though an occupant or manager of those premises is responsible for the premises and regardless of any agreement between the owner and another that imposes or attempts to delegate responsibility for the premises to the other."

(8) Section 107.2 is hereby amended to read as follows:

"107.2 Form. Such notice prescribed in Section 107.1 shall be in accordance with all of the following:

"(a) General. The code official and any officer, as the term officer is defined in City Code Section 19-66, are authorized to give written notice to any owner or occupant whose building or property is in violation of the provisions of this code. Such notice may be personally served upon such person or, if not personally served, shall be deposited in the United States mail, addressed to the owner of record at the address on the assessment roll of the Larimer County Assessor or at such other, more recent address as may be available to the City.

"(b) Notice. The notice shall include a description of the real estate sufficient for identification, include a statement of the violation or violations and why the notice is being issued, and state that, if the violation is not corrected on or before the date and time stipulated in the notice, a citation may issue and the correction or demolition may be done by the City and any costs of abatement, repair or demolition, including the cost of inspection, the cost of any grading or sloping necessary to protect the public safety and other incidental costs in connection therewith and an amount not to exceed one hundred (100) percent of the costs for carrying charges and costs of administration will be charged against the property, in addition to any other penalty and costs or orders that may be imposed. The notice shall also state that, if the owner desires a hearing before the Building Review Board to contest the declaration and order of vacation, condemnation, repair, removal or demolition such owner shall request a hearing, in writing, to the code official within ten (10) days of mailing of the notice. The notice shall further state that failure to timely file a request for such hearing shall be a waiver of the right to contest the declaration, assessment or order at any later date.

"(c) Abatement. If the building or property has not been brought into compliance with this code within the time period set forth in the notice and, if the owner has not requested a hearing before the Building Review Board to contest said declaration or any other code official's orders as provided in Subparagraph (1) above, the demolition or abatement may be performed by City personnel or by private contractors, as the code official shall determine. In the event of such demolition and abatement by the City, the cost, including inspection, demolition and any other incidental costs in connection therewith, and an amount not to exceed one hundred (100) percent of the costs for carrying charges and administration, shall be assessed against the offending property.

"(d) Assessment. Any cost assessment shall be a lien in the several amounts assessed against each property until paid and shall have priority over all other liens, except general taxes and prior special assessment liens. If any such assessment is not paid within thirty (30) days after it has been certified by the code official and billed by the Financial Officer or his designee to the owner by deposit in the United States mail addressed to the owner of record at the address as shown on the tax rolls or such other, more recent address as may be available to the City, and any agents, representatives or occupants as may be known, the Financial Officer or his designee is hereby authorized to certify to the County Treasurer the list of delinquent assessments, giving the name of the owner as it appears of record, the number of the lot and block and the amount of the assessment plus a ten-percent penalty. The certification is to be the same in substance and in form as required for the certification of other taxes. The County Treasurer, upon receipt of such certified list, is hereby authorized to place it upon the tax list for the current year and to collect the assessment in the same manner as general property taxes are collected, together with any charges as may by law be made by the County Treasurer and all laws of the state for the assessment and collection of general taxes, including the laws for the sale of property for taxes, and the redemption thereof shall apply to and have full force and effect for the collection of all such assessments. Notwithstanding the foregoing, if the offending building or property is not subject to taxation, the City may elect alternative means to collect the amounts due pursuant to this code, including the commencement of an action at law or in equity and, after judgment, pursue such remedies as are provided by law."

(9) The title of Section 108, along with Sections 108.1, 1081.1, 108.1.2, 108.1.3 and 108.1.4 are hereby amended to read as follows:

"108.1.1 Substandard structures. A substandard structure is one that may pose a risk to the life, health, property or safety of the occupants thereof or the public, even though it does not constitute a dangerous structure as defined in Section 108.1.5, either because the structure lacks the equipment necessary to protect or warn occupants in the event of fire, or because it contains substandard or missing equipment, systems or fixtures, or is damaged, decayed, dilapidated or structurally unsound.

"108.1.2 Substandard equipment and fixtures. Substandard equipment or fixtures may include any boiler, heating equipment, elevator, moving stairway, electrical wiring or device, flammable liquid containers, potable water, plumbing, sanitation systems or fixtures or other equipment on the premises or within the structure which is in such disrepair or unsound condition that the equipment or fixtures pose a potential risk to life, health, property or safety of the public or occupants of the premises or structure.

"108.1.3 Structure unfit for human occupancy. A structure is unfit for human occupancy whenever the code official finds that such structure is unlawful or, because of the degree to which the structure is in disrepair or lacks maintenance, is unsanitary, vermin or rat infested, contains filth and contamination, or lacks ventilation, illumination, sanitary or heating facilities or other essential equipment required by this code, or because the location of the structure constitutes a hazard to the occupants of the structure or the public.

(10) Section 108 is hereby amended by a new Section 108.1.5 which reads in its entirety as follows:

"108.1.5 Dangerous structure or premises. A structure or premises is dangerous if any part, element or component thereof is no longer within its serviceability limit or strength limit state as defined in this code or, when considered in totality, the structure or premises pose an imminent threat to the health and safety of the public or the occupants of the structure or premises as referenced in Appendix A of this code."

(11) Section 108.2 is hereby amended as follows:

"108.2 Vacant Buildings and structures.

"(a) General. When a building or structure is vacant and unsecured or unfit for human habitation and occupancy the code official is authorized to post a 'Vacant Building Notice' on the premises and order the structure closed up so as not to be an attractive nuisance. Upon failure of the owner to close up the premises within the time specified in the order, the code official shall cause the premises to be closed and secured through any available public agency or by contract or arrangement by private persons, and the cost thereof shall be charged against the real estate upon which the structure is located and shall be a lien upon such real estate and may be collected by any other legal resource."

"108.2.1 Vacant and dangerous buildings registry.

(12) Sections 109.1, 109.2, 109.3 and 109.5 are hereby amended to read as follows:

"109.1 Imminent danger. When, in the opinion of the code official, there is imminent danger of failure or collapse of a building or structure which endangers life, or when any structure or part of a structure has fallen and life is endangered by the occupation of the structure, or when there is actual or potential danger to the building occupants or those in the proximity of any structure because of explosives, explosive fumes or vapors or the presence of toxic fumes, gases or materials, or operation of defective or dangerous equipment, the code official is hereby authorized and empowered to order and require the occupants to vacate the premises forthwith. The code official shall cause to be posted at each entrance to such structure a notice reading as follows: "This Structure Is Dangerous and Its Occupancy Has Been Prohibited by the Code Official." It shall be unlawful for any person to enter such structure except for the purpose of securing the structure, making the required repairs, removing the hazardous condition or demolishing the same.

"109.2 Temporary safeguards. Notwithstanding other provisions of this code, whenever, in the opinion of the code official, there is imminent danger due to a dangerous condition, the code official shall order the necessary work to be done, including the boarding up of openings, to render such structure temporarily safe whether or not the legal procedure herein described has been instituted; and shall cause such other action to be taken as the code official deems necessary to meet such emergency.

"109.3 Closing streets. When necessary for public safety, the code official shall temporarily close structures and close, or order the authority having jurisdiction to close, sidewalks, streets, public ways and places adjacent to dangerous structures, and prohibit the same from being utilized.

If not notified prior to disconnecting, the owner or occupant of the building, structure or service system shall be notified in writing as soon as feasible thereafter."

(14) Section 110.1 is hereby amended to read as follows:

"110.1 General. The code official shall order the owner of any premises upon which is located any structure, which in the code official's judgment is so old, dilapidated or has become so out of repair as to be dangerous, unsanitary or otherwise unfit for human habitation or occupancy, and such that it is unreasonable to repair the structure, to demolish and remove such structure; or if such structure is capable of being made safe by repairs, to repair and make safe and sanitary or to demolish and remove at the owner's option; or where there has been a cessation of normal construction of any structure for a period of more than two (2) years, to demolish and remove such structure."

(15) Section 111 is hereby amended by revising the Section in its entirety to read as follows:

The failure of the code official to serve any person required herein to be served shall not invalidate any proceedings.

"111.5 Hearing period.
