I was recently inspecting a new construction home and found many code violations. I spoke to the builder and he assured me the city had approved all the conditions in the home. One problem I found was an incomplete seperation wall on the ceiling of the garage (there were bedrooms above) The drywall on the ceiling left about 1" to 2" gaps at perimeter, gaps around fixtures, plumbing and ducts. The builder said the city inspector said the seperation wall wasn't even necessary on the ceiling. I also found electrical splices not in junction boxes, junction boxes with no covers, uninsulated flexible air supply ducts in the attic space, approximately half the insulation needed in the attic space, plumbing leaks and on and on. These weren't concealed issues either. Another one that perplexed me was the foundation wall had a beam pocket built in however the main support beam was bearing on the sill plate and not in the beam pocket. Where the main beam was bearing on the sill plate, there was no concrete foundation support beneath the sill plate due to the mistakenly installed beam pocket. How could these things get over looked? Is this common? What kind of assurances could I provide to my clients when I come in after the home is "complete" about the rest of the construction? Should I inquire with the city about code enforcement?
