It is difficult for people to look around in a business district or in a residential community without seeing the handiwork of general contractors. The construction of great office buildings, shopping centers, malls, strip malls, the streets, and highways that take people to them are made manifest due to the skills of contractors. When people say contractors, that includes general contractors as well as sub contractors. Because most buildings are built specifically to local building codes, the general contractor is the one held responsible for the overall job site being in compliance with proper building codes. Due to that fact, often jobs are awarded to local general contractors because of their familiarity with the workings of local inspection departments. Local general contractors may employ sub contractor from out of town to actually do the bulk of the work, but they are still responsible for the work done in every aspect.
