Maintenance of Exterior Walls and Enclosures (sections through of the Chicago Building Code) was first adopted by the City of Chicago in Its current Rules and Regulations became effective on October 1, Previous iterations of the Chicago Facade Ordinance dating back to 1970s were rescinded, reconsidered and tabled by former City Councils. Program Description. Applies to all buildings that are 80-ft. or more in height. o Critical Examination Program. Category mandated frequencies, close-up inspections performed on a minimum of one representative drop on each public way (not less than 24-ft wide). Category I, 12 year intervals, Category II and IV, 8 year intervals, Category III, 4 year intervals. One inspection opening per facade is required for Category II and Category III buildings that are more than 50 years old. o Ongoing Inspection and Repair Program. When participating in the Critical Examination Program, midpoint inspection and report required for each category; Category I, 6th year, Category II and IV, 4th year, Category III, 2nd year. Method by which the inspection is performed is left to the discretion of the design professional (may be performed from afar, up close, or combination thereof). o Short Form Program. Under the October 22, 2009 Rules and Regulations, owners of occupied buildings, regardless of building category, may choose to file Ongoing Inspection and Repair Program ( Short Form ) reports every second year and not file Critical Examination Program reports at category mandated frequencies, provided that all of the following conditions are met: There is a Critical Examination Program report on file that has been accepted by the Department of Buildings. The most recently filed report, either Critical Examination Program report or Ongoing Inspection and Repair Program report, classified the building as safe or safe with a repair and maintenance program. Owners notify the Department of Buildings in writing of their intent to file only Short Form reports. Building Categories. Category and Program dictates the frequency with which reports are filed with the Department of Buildings. o Category I - buildings constructed with exterior walls and enclosures that are primarily reinforced with, or are in direct contact with, non-corrodible metal. o Category II - buildings constructed with exterior walls and enclosures that are primarily reinforced with, or are in direct contact with, (i) corrosion-resistant metal, or (ii) corrodible metal that is protected by flashing and corrosion-resistant metal anchors. o Category III - buildings constructed with exterior walls and enclosures that are primarily reinforced with, or are in direct contact with, corrodible metal.

Link to information on City of Chicago website Exposed Metal Structures Chicago Building Code reference. Architectural and Structural Iron Inspection report is defined in Chapter to of the Chicago Building Code. The program applies to exposed metal stacks, tanks, signage, fire escapes, canopies, revolving doors, antennas, cooling towers, flagpoles, and metal cornices. Section of the Chicago Building Code requires that all metal structural members be adequately protected against corrosion and be scraped and painted at least once every three years. FAQ. Can the existing fire escapes be removed from the building to avoid costly routine maintenance? If an analysis of the existing means of egress indicates that existing fire escapes are not necessary, then the existing fire escapes may be removed. However, in most residential buildings where fire escapes exist, significant improvements and/or repairs are necessary to the existing means of egress to accommodate removing existing fire escapes. Link to information on City of Chicago website Energy Code Chicago Building Code reference. International Energy Conservation Code, Chapter to of the Chicago Building Code. Intent. Regulates the design and construction of buildings for the effective use of energy and intended to provide flexibility to permit the use of innovative approaches and techniques to achieve the effective use of energy. Modeled on the 2006 International Energy Conservation Code (IECC) Applies to: o All new buildings. o Additions, alterations, renovations or repairs to existing buildings. o Buildings changing occupancy and increasing demand for fossil fuel or electrical energy. o Replacement of entire building systems: exterior wall finishes, roofing, windows, mechanical, service water heating, electrical or lighting Does Not Apply to: o Unaltered portions of existing buildings o Historic buildings that are part of a historic district, designated Chicago Landmark or listed on State or National Register of Historic Places Minimum Roof Insulation Requirements o Residential: Ceiling with attic: R-38 (12 inch batts, batts= R-3.6 per inch) Ceiling without attic: If space limited, can be reduced to R-30 (up to 500 sq.ft. max) o Commercial: Insulation continuous entirely above deck: R-20 (3.3 inch isocyanurate, iso = R-6.0 per inch) Metal joists: R-19 with R-5 thermal blocks between joists and deck Wood framed: R-30 between joists (9.5 inch batts)

The 2002 CECC Limited Roofing Selections. It required a minimum solar reflectance of 0.65 or 0.50 after 3 years and an emissivity of 0.90 for roof coverings. o Compliant Roofing: white single-ply membranes (PVC and TPO), built-up roofing coated white, modified bitumen roofing coated white o Non-Compliant Roofing: gravel/smooth surfaced built-up roofing, granular/smooth surfaced modified bitumen roofing, black EPDM roofing, ballasted roofing, metal roofing The 2009 CECC Expanded Roofing Selections o Minimum solar reflectance varies by roof slope: Low slope roofs (0 to 2:12 pitch): 0.72 initially or 0.5 after 3 years. Minimum reflectance reduced to 0.3 for roofs covered by more than 50% vegetative roofing, ballasted roofs with 15 lbs./sq.ft. (river rock or pavers), replacing existing built-ups with new built-ups. Medium slope (2:12 to 5:12 pitch): 0.15 initially Steep slope (greater than 5:12): no minimum o Exemptions: vegetative roofs (extensive or intensive), photovoltaic and solar thermal equipment, rooftop deck covering maximum 1/3 of roof o For low slope roofs repairs shall meet reflectance when roofing was originally installed. For medium slope roofs repairs and partial replacement are limited to less than 50% over a 36 month period. o Compliant Roofing: built-up roofing with flood coat and gravel or coated white, modified bitumen roofing with granular surfaced cap sheets or coated white, ballasted roofing, white single-ply membranes (PVC, TPO and EPDM), some metal roofing. o Non-Compliant Roofing: uncoated smooth surfaced built-up roofing, uncoated smooth surfaced modified bitumen roofing and black EPDM roofing Changes in the 2012 International Energy Conservation Code. Published in Spring To be adopted by Illinois in January o Increases minimum roof insulation requirement from R-20 to R-25. o Includes exception language for tapered insulation o Requires a continuous air retarder in the roofing system Link to information on City of Chicago website view.html Life Safety Ordinance Chicago Building Code reference. Chapters through of the Municipal Code of Chicago requires buildings that exceed 80-feet in height and that are not protected by a previously approved automatic sprinkler system to have an initial Life Safety Evaluation (LSE) performed. No action required if, based on the use of a scoring system described by rule to conduct the LSE, the licensed professional engineer or licensed architect determines that the building achieves the minimum score required. If, based on the use of a scoring system described by rule to conduct the life safety evaluation, the licensed professional engineer or licensed architect determines that the building does not achieve the minimum score required on the Life Safety Evaluation, the building owner shall submit the Life Safety Evaluation to the Department of Buildings and the Bureau of Fire Prevention along with either: (1) a proposal to protect the building throughout with an automatic sprinkler system meeting the

Link to information on City of Chicago website Permits Building Permits. As of July 1, 2012, applications and supporting documents (drawings and/or specifications) for building permits are required to be submitted to the City of Chicago electronically. Repair Permits. Requirements are generally less stringent; application can be submitted by owner, contractor, or permit expeditor with the contractor s license number, copy of the signed contract, and the permit fee. Links to information on City of Chicago website ew.html Reserve Studies Scope. A general assessment of the building envelope, including the facade, windows, and roof; and accessible portions of common interior spaces. Also includes evaluations of the elevators and mechanical, electrical, plumbing and fire protection (MEP/FP) systems. In some instances, the common elements of the commercial and/or retail portions of buildings (for mixed used properties) are included in the reserve study. Opinions of Probable Cost. The report generally includes an opinion of probable cost to correct deficiencies observed during the assessment. Costs are generally categorized to align with maintenance or repairs that are expected to be required in the first year, maintenance or repairs that are expected to be repaired in the next five years, or maintenance or repairs that are expected to be repaired in the next ten (to twenty) years. Cost presented in most reserve studies are opinions only, and therefore, should not be relied on solely to establish firm capital budgets. Competitive bids using a set of scope or repair drawings and specifications should be obtained if accurate costs are required. New Technologies Coordinate Exterior Envelope Repair and Maintenance Projects Building Enclosure Commissioning (BECx) Thermography Lessons Learned Avoid deferred maintenance. Deferred maintenance often leads to major future replacement costs. Consult the experts. Most licensed design professionals (architects and engineers) have a broad range of expertise and some consultants have very specialized expertise. Be sure to seek advice from a consultant with expertise to appropriately identify solutions to building problems.
