Construction CodeCommunicatorState of New JerseyJon S. Corzine, GovernorDepartment of Community AffairsCharles A. Richman, Acting CommissionerVolume 21, Number 1Spring/Summer 20092009 Building SafetyConferenceCPVC Fire Sprinkler SystemDrop Installations“Building a Safer Tomorrow”It has come to the attention of the Department thatsome fire sprinkler systems utilizing ChlorinatedPolyvinyl Chloride (CPVC) pipe are being installedincorrectly. In one city, where 13 high rise buildingswere being constructed, an observant Fire SubcodeInspector noticed the sprinkler contactor installing thesprinkler head drops incorrectly. The inspector askedthat a random sample of heads be removed to checkfor obstructions. The problem is that the sprinklerheads are being installed in the drops before the dropsare installed onto the branch lines. When the drop isinstalled the adhesive drips down through the drop andseals the sprinkler head cap in place causing ablockage.thThe 28 annual New Jersey Building SafetyConference was held this year from May 6 through May8 at the Trump Taj Mahal in Atlantic City. As our themeabove aptly suggests, the focus of this year’sconference was on meeting the current challengesfaced throughout our industry while assuring that weare ready for the many innovations and new techniquesthat the future will bring, making sure that our tomorrowis, indeed, safer.The “Crackerbarrel” on the first evening had arecord setting 46 tables covering varying topics ofinterest ranging from floodplain management to anopportunity to speak with our Director, Cynthia Wilk,about the many hot topics the Division is working on tomeet the needs of our local inspectors and officials.There were 13 seminars held each training day runningacross the spectrum from electrical code updates toswimming pool and spa safety.The manufacturer’s installation specification hasrequirements on how to install these drops. Therequirements clearly state that the heads are not to beinstalled until the adhesive has had time to cure. Thecure time could be as long as 48 hours or as short as15 minutes before a test could be conducted on thepipe.The NFPA referenced standard has noinstallation information about these types of drops. Themanufacturer’s specifications strongly recommend thatthe contractors attend an installation class before theystart installing the product and attend an update classevery two years thereafter.One of the major events at the Conference, asalways, is the opportunity to honor those whosecommitment and dedication over the past year isrecognized by their associations- the Inspectors andTechnical Assistant of the Year.

Therefore, to clarify:5. No permit surcharge fee shall be collected forwork consequential to a natural disaster whenthe local code enforcement agency is waivingits fee.1. No permit surcharge fee shall be collected forpre-engineered systems of commercial farmbuildings.2. No permit surcharge fee shall be collected forpermits to perform asbestos abatement or leadabatement.3. No permit surcharge fee shall be collected forpermits for the construction or rehabilitation ofresidential units that are to be legally restrictedto occupancy by households of low- ormoderate-income.4. No permit surcharge fee shall be collected fordemolition of buildings or structures.Further, where the Uniform Construction Code Actitself specifies that no training fee or permit surchargefee shall be charged, no permit surcharge fee shall becharged. Those instances are:6. The issuance of a Construction Permit for theinstallation or alteration of solar energy heatingor cooling systems.7. The issuance of a Construction Permit for theconstruction, reconstruction, alteration orimprovement designed and undertaken solelyto promote accessibility by disabled persons.continued on page 5

The IFC is not adopted as part of theUCC. Therefore, when the International Building Code(IBC) requires installation in accordance with the IFC,the un-amended edition of the IFC must be used. TheIFC/2006, New Jersey edition is used only formaintenance inspections by the Fire Official or FireInspector.If you have any questions, please feel free to callme at (609) 984-7609.Source:Michael E.

The complete list of itemscan be found at Section 402.4.1 of the IECC/2006.Furthermore, the IECC/2006 specifically calls outrecessed lighting at Section 402.4.3 to limit air leakagebetween conditioned and unconditioned spaces withthree methods; they are as follows:If you have any questions on this matter, pleasecontact me at (609) 984-7609.Source:Rob AustinCode Assistance Unit

Page 6Construction Code Communicatorcontinued from page 1The Foundation of GoodPartnershipsAll partnerships that work well have one thing incommon. Whether it’s a two man beach volleyballteam, a doubles tennis team, or a couple on Dancingwith the Stars, partnerships are most successful whenthe partners coordinate what they are doing. In orderfor them to do this they need to either have workedtogether in the past or communicate well with eachother. The same need to coordinate applies on manyconstruction projects, especially modular projectswhere the installation instructions for the modularbuilding are prepared by the manufacturer while thefoundation is designed by someone else. If thepartners are not in sync, the dancing can get prettyugly.There are a couple of areas in modular homeswhere the dancers often step on each other's toes.The first is the center support where two modules areplaced on the foundation. This can be treated in one oftwo ways. One way is to provide continuous supportunder the edge of each module that runs down thecenter of the foundation. The other is to design theband boards (essentially rim joists) to act as a girderwith intermediate supports. The first option is relativelystraight forward; the second requires somecoordination. For the second option to be used, thefoundation designer needs to determine how the twoband boards need to be fastened and where thesupports need to be located. The location of thesupports is dictated by a number of factors, includingthe band board material, the load, and the location ofthe band board splices (if any). That’s where thecoordination comes in. The foundation engineer mustcoordinate the submitted foundation plan with the waythat the modules were constructed.A second place where the dancing can go awry isthe lateral support provided for the first floor joists thatrun parallel to the foundation wall. Foundation walls,for the most part, rely on the first floor joists for supportof the top of the foundation wall against lateral pressurefrom the soil on the outside (unbalanced fill). For joiststhat run perpendicular to the foundation wall, thebracing is provided by the joist itself. For joists that runparallel to the foundation, the support must be providedby blocking between joists so that the force on thefoundation wall is transferred to the floor assemblyrather than just to the rim joist. This is discussed inSection R404, Foundations and Retaining Walls, of thecontinued on page 8The local officials need to keep a close watch onthese installations to make sure that the contractors arefollowing the manufacturer’s specifications. If thesedrops are being installed incorrectly, a random sampleof the heads should be pulled in each area affected tocheck for any blockage. If blockage is found, all theheads should be replaced.If you have any questions, please feel free to callme at (609) 984-7609.Source:Michael E. WhalenCode Assistance UnitALERT! Changes areComing to the CCCNearly two years ago, the Construction CodeCommunicator was moved from a printed newsletter toone that is posted on the Division's web site. Inaddition, it was reduced from four issues each year tothree. This year, it is changing again.The Construction Code Communicator will continueto be posted on the Division's web site. It will beposted three times this year in spring/summer, fall, andwinter/2009 issues. Next year (2010), it will be postedtwice a year, in spring/summer and fall/winter issues.It will be posted in the Department's document library,so that, when it is posted, each registered user willautomatically receive an e-mail notification.In addition to posting the Communicator, theDepartment will use its document library to post otherdocuments that are important to code enforcement.We will also publish short alerts and updates in an“Alerts” or "Hot Topics" section of the web site.It has become faster and more efficient tocommunicate through the web site and documentlibrary, so: If we do not have your municipal e-mail address,please contact Sue Lydon atORA@dca.state.nj.us.

Volume 21 Number 1 Spring/Summer 2009Garden-Type Utility Shedsand Similar Structures –ClarificationOn April 20, 2009, the Department repealedN.J.A.C. 5:23-9.9, Foundation systems for garden typeutility sheds and similar structures. The provisions ofthis section were moved within the applicable chaptersof the building and one-and two-family dwellingsubcodes.Therefore, the exceptions in Section1805.2 of the International Building Code/2006(IBC/2006) and Section R403.1.4 of the InternationalResidential Code/2006 (IRC/2006) have been modifiedto reflect old N.J.A.C. 5:23-9.9. Both the IBC/2006 andIRC/2006 allow free standing storage-type buildings tobe built without a foundation to frost-depth as long asthe building meets the following three conditions:1) The building presents a low hazard to human life inthe event of failure; these include, but are notlimited to, agricultural buildings, temporarybuildings, and minor storage facilities;2) The building an area of 600 square feet or less forlight framed construction (LFC), or 400 square feetor less for other than light-framed construction(OTLFC); and3) The building has an eave height of 10 feet or less.However, unlike old N.J.A.C. 5:23-9.9, footingswere required in all cases to be at least 12 inchesin depth. A brief summary follows (all 10 feet orless in height): 100 ft2 or less – footings of 12 inches deep notrequired provided the structures do not containutility connections and are of sufficient weight toremain in place or be anchored to the ground(like old N.J.A.C. 5:23-9.9(a)) More than 100 ft2 up to 200 ft2 – footings of 12inches deep not required provided the structuresare dimensionally stable without the foundationsystem and do not contain utility connections. Astructure shall be considered dimensionallystable if it is provided with a floor system that istied to the walls of the structure such that it reactsto loads as a unit. These structures shall be ofsufficient weight to remain in place or shall beanchored to the ground (like old N.J.A.C. 5:239.9(b)) Buildings of more than 200 ft2 up to 600 ft2 LFCor 400 ft2 OTLFC – Footings of 12 inches deeprequired Buildings of more than 600 ft2 LFC or 400 ft2OTLFC – Footings to frost requiredGarden-type utility sheds require a constructionpermit for building work unless the structure is 100square feet or less in area, and 10 feet or less in height,Page 7and accessory to buildings of Group R-2, R-3, R-4, orR-5, and does not contain a water, gas, oil or sewer
