Most new homes are well built. The quality of construction and errors will typically vary from builder to builder. A common response to the question of obtaining a new construction home inspection is “everything is already inspected by the building department”. The building department will only inspect for plan an code compliance and will not care about functional or cosmetic defects. The building department inspectors also do not have 2-3 hours to inspect every home.

Below are a sampling of construction defects identified during the past few years during several new construction inspections. Cosmetic defects or functional defects were not included in this list. The homes were built by small builders, national builders and ranged from starter homes to homes priced over 1.5 million dollars. Most of these home had received the certificate of occupancy (“building final”).
