From: Tim Hansley, City Manager M;.;.,,,g Initiated by Peter Lenz, Chief Building Official Subject: Ordinance 22-96 Date: February 29, 1996 Over the next few months, Council will be receiving several pieces of proposed legislation concerning the enforcement of building standards in the City of Dublin. There are two reasons for this; first, the normal three-year cycle for the approval of new Ordinances and second, because the insurance industry, over the last few years has suffered major losses due to windstorms and fire, investigation by their controlling group indicates that enforcement and adoption of building codes had a direct relationship to the losses suffered by their carriers. Starting with the year 1995, a series of pilot programs were started in various states, This program will become nationalized and Ohio will be the recipient of their actions in 1998. The Insurance Standards Organization (ISO), will be adopting a "scorecard" or "gradecard" for building departments. On the basis of this "gradecard", insurance rates for homeowners and businesses will be adjusted, either upward or downward. In other words, a good rating schedule will reduce the cost of hazard insurance for homeowners and businesses, The 1995 CABO, which ..,- you will be debating in public hearings on Monday, March 4, is the first of these pieces of legislation. - It is our goal to adopt these standards with a minimum number of local modifications. There are currently a series of meetings being held by OBOA (Ohio Building Officials Association), and after another series of public hearings that will be held statewide, OBOA will recommend to all jurisdictions adoption of OBOA sponsored amendments, in order to promote, as much as possible, statewide uniformity in the One, Two and Three Family building codes. OBOA is a recommending agency and without statutory force. The ordinance before you this evening has been modified in conjunction with meetings held with the BIA (Building Industry Association) and have been discussed on Wednesday morning, February 28, at the Building Division Annual Residential Contractor's Breakfast. The amended ordinance, which has been presented to you today, includes the input of these meetings, There are a couple of "hot-button" issues that you should be aware of The "rise and run" of residential stairs has been hotly debated in the builder community. The City of Dublin, in the crafting of it's ordinance has modified the 1995 CABO to the extent that the "rise and run" ~",..,"" ~"""'" Dublin City Council Page 2 February 29, 1996 requirements for stairs is tied to the commercial building code (the OBBC), residential R2 and R3 Construction types. These are multiple, single-family (townhouses) or apartment type units, which clearly have similar characteristics to the One, Two and Three Family Dwelling Code, The - purpose of this tie-in, is that, as the 1995 BOCA is debated for adoption in the state of Ohio, probably as the 1997 OBBC, the issue of stair tread rise and run will again come to the forefront - and, if adopted, under BOCA language, the OBBC and the CABO codes will be consistent with the lowered rise and widened tread. Another subject that will be presented to the building community, through this ordinance, is the requirement for passive radon mitigation systems. We have had meetings through OCCINIBS (the Ohio Consultative CouncillNational Institute of Building Sciences) in the City of Dublin, concerning the real hazards and requirements of radon mitigation in our community. We are considered a Class 1 category area, which has a high likelihood of radon incidence, and the cost of passive mitigation will pre-empt the cost of a major mitigation system being required at the time of single-family resale, These systems average between and $1500.00 and $2500.00 as part of the selling negotiations in many houses today. The system, when properly installed, provides the underground piping so that if elevated readings of radon are discovered in the testing of a house, a simple mitigating fan addition can bring the radon level to an acceptable standard as defined by EP A. You will find a book in your packet on radon mitigation that was issued by Underwriters Laboratories. The third major area of change in the 1995 CABO is the adoption of a requirement for Carbon Monoxide detection, The City of Dublin, during the heating season, experiences a number of calIs each month from voluntary Carbon Monoxide detectors, Carbon Monoxide is a silent killer, with - it's symptoms often misdiagnosed, until serious injury or death results. ...... You will also note a number of locally adopted ordinances that have been in our codes are no longer necessary. Many of the issues in this category have been adopted as part of the 1995 CABO standard. This includes such items as foundation waterproofing and bathroom safety glazing. As a part of the rating system for ISO, the insurance industry will be reviewing our adopted codes. Upon the passage of the CABO code, Building Standards will be submitting a Property Maintenance Code to Council for debated action, this should be following in about 30 days, c:\wps 1 \doc\memo\council.304 fll'~';.. ,,'" .,,.;4 n'[ I "a, en" ~' ,>It':_ '-:O;,'!l' Vh,_._.'_____n, . .
