While you may be competent in and enjoy many aspects of building an accessory building, the same thing might not be true for the logistics. Whether it is coordinating with suppliers or navigating the rules and regulations of the City of Kelowna or Regional District, or abiding by the building codes, a professional contractor has the knowledge and experience to ensure these processes go smoothly and all boxes are checked. They also might be able to make suggestions or give you ideas about the best options to ensure the integrity of your structure over time while maintaining cost efficiency.
