What is the difference between 41100 and the construction codes 41201 and 41202?
Code 41100 is for developing building projects. That means pulling together land, funding and consents, then subcontracting the build. Codes 41201 and 41202 are for physically constructing commercial and domestic buildings. A developer who also builds can list both. Small builders sometimes pick 41100 when 41202 fits better. The public record accepts either, but the right code helps insurers and lenders read the business correctly.
