1 Building Permit Inspectins Inspectin Stages District f Lake Cuntry Bttm Wd Lake Rad Lake Cuntry, BC V4V 2M1 t: f: Inspectin Request Line lakecuntry.bc.ca Purpse T infrm, staff, building cntractrs and the general public f the guidelines t aid Builders in the prper preparatin fr calling in fr inspectins. The bjective is t prmte wrker s safety in accrdance with WrkSafe BC, Occupatinal Health and Safety and the District f Lake Cuntry requirements, avid delays and additinal fees by prviding upfrnt infrmatin that prepares the Builder in advance. Building bulletins are part f the District s custmer service prgram. They are designed t prvide an imprved understanding f the Building Cde and Building Science and t reduce the csts assciated with crrecting infractins. Backgrund Inspectins help ensure that renvatin r cnstructin wrk cmplies with the apprpriate by-laws, and matches wrk authrized by the permit. Inspectins als help the District advance its gals cncerning life safety, accessibility, and mre. The cmplexity f mdern buildings and technlgies ften means several inspectins f a building are required, including inspectins f the plumbing, structural, health, safety and envirnmental systems. The District f Lake Cuntry has been experiencing an increase f requested inspectins with a very small windw f time t perfrm the inspectin requested by the builder. Als, there have been numerus times when the inspectr has attended the site t find the prject nt ready fr inspectin. Recently District f Lake Cuntry Building Inspectin staff are finding wrksites that d nt meet the minimum requirements fr safety as detailed by Wrksafe BC and Occupatinal Health and Safety Regulatins. The District f Lake Cuntry requires their wrkplace t be a healthy and safe envirnment. T achieve this, the District has established and will maintain an Occupatinal Health and Safety prgram designed t prevent injuries and diseases. The District is respnsible fr ensuring wrkers are prvided with adequate instructin in health and safety and fr addressing unsafe situatins in a timely, effective manner. All wrkers and service cntractrs are required t wrk safely and t knw and fllw District f Lake Cuntry guidelines fr safe wrk prcedures. The right t refuse unsafe wrk is central t Occupatinal Health and Safety legislatin. The District f Lake Cuntry expects that all emplyees and their supervisrs will understand their bligatins in this regard and building inspectrs will refuse t perfrm inspectins if they feel the site is unsafe.

2 Building Permit Inspectins Inspectin Stages Page 2 Implementatin While staff strive t accmmdate cntractr needs wherever pssible, the District f Lake Cuntry is unable t accmmdate times fr inspectins due t the high vlume f permits currently being experienced. If yur permitted cnstructin r imprvements are ready fr a required building r trades inspectin, yu must arrange t have a District inspectr t inspect the wrk by calling r by bking nline at Inspectins must be bked 24 hurs in advance, as utlined in the Building Bylaw. When yu phne t arrange fr an inspectin, be ready t prvide: Permit Number Address f the site Type f inspectin required Date f requested inspectin If yu need t cancel a scheduled inspectin, please call Inspectins shuld nt be cancelled after 8:00 am f the scheduled inspectin date. Inspectins cancelled after this deadline may be subject t a $50 re-inspectin fee. Re-inspectin Fee Plicy The intent f the Cmmunity Services Department is t wrk tgether with ur custmers and supprt them thrugh the building prcess. T that end the District has develped this prcedure t enable custmers t educate themselves and be prepared fr required inspectins. This prcedure is meant t remind cntractrs that they have a respnsibility t ensure cnstructin is carried ut accrding t the prcedure utlined and t reslve deficiencies nted by the inspectr. A re-inspectin fee ($50), as utlined in the Fees Bylaw, may be applied fr the fllwing reasns: Failure t fully crrect any previus nted deficiencies recrded n the inspectin reprt; A cntractr f persn requesting an inspectin and wrk is nt ready fr the requested inspectin; If the wrk has prgressed further than it allws an Inspectr t d the required inspectin, wrk will need t be uncvered in rder t verify the cmpliance f the wrk; If the cntractr r persn fails t request a required inspectin; If the inspectin is cancelled after the scheduling deadline; Failure f the cntractr/wner t ensure a safe and accessible site; If the plans r required dcuments (i.e. truss, beam, flr layuts and specificatins) are nt nsite; and, Any ther reasn similar t thse nted abve.
