The public health, safety and welfare is in part dependent on the conservation, rehabilitation and reuse of the existing building stock; that the application of new construction requirements and standards to the rehabilitation of existing buildings may unnecessarily increase the cost thereof; that adequate enforcement of minimum housing and other standards for safe and decent human habitation requires expeditious and cost effective procedures for encouraging the rehabilitation of existing buildings; that rehabilitation is a major mechanism for increasing the health and safety in existing buildings; and that adequate resources in the form of public and private initiatives exist to increase and expand the incidence of rehabilitation when such rehabilitation is regulated by reasonable requirements.
(Prior code § 78.1-1)
It is therefore the purpose of this code, to the maximum extent consistent with basic standards of human health and safety to:
(a) Promote the rehabilitation of existing sound buildings by allowing for differences between rehabilitation and new construction requirements in the application of the provisions of this code.
(b) Encourage the rehabilitation, the utilization of innovative and economic materials and methods of construction.
(c) Encourage the agencies charged with the enforcement of this code and the officers thereof to:
(1) Apply the provisions of this code to buildings to be rehabilitated in a manner consistent with the purposes stated herein;
(2) Exercise discretion and employ resourcefulness in the evaluation of code compliance of rehabilitated structures in a manner consistent with the purposes stated herein.
(Prior code § 78.1-2)
Where there are not specific provisions in this chapter applying to the repair, alteration of, additions to, and changes of use of any existing building or structure or part thereof, then such building or part thereof shall be made to comply with the pertinent provisions of this Code for new buildings or structures.
(Prior code § 78.1-3)
All repairs, alterations, additions and changes of use in existing buildings must comply with all applicable sections of the Chicago Zoning Ordinance and with the special provisions of Section 13-200-050 through and including 13-200-090. Existing private detached garages and other buildings accessory to an established residential use may be altered, repaired, replaced or enlarged with new construction matching the existing construction up to the limits of the existing zoning and/or building construction requirements on that zoning lot.
(Prior code § 78.1-4)
No existing building located within the fire limits shall be increased in height or area unless it is of a type of construction permitted for new buildings within the fire limits.
The fire limits are defined in Chapter 13-116.
(Prior code § 78.1-5; Amend Coun. J. 9-6-17, p. 55278, Art. II, § 46)
