My son wants to build a treehouse. What are the safety requirements for a treehouse?

Treehouses should be built in accordance with local building codes and regulations. Additionally, you must ensure that the structure is secure enough to withstand the weight of people climbing on it. You should also check for any potential hazards such as rotting or weak branches, which could cause the treehouse to collapse. Finally, make sure to inspect the tree regularly and take steps to prevent insect infestations.
