What happens if I don't get a permit?

The property owner may be subject to legal action for failure to obtain a building permit. If you carry out a renovation project that requires a building permit without having one, Village Building Department representatives may issue a "Stop Work" and or a "Cease and Desist" order, which remains in effect until you obtain a  permit. If the work doesn't meet the requirements of the Building Code, you may well have to redo the work at your own cost.
Work performed with out a required building permit may hold up the sale of your property in the future and may also affect an insurance claim. Before any work begins on your home, check with your insurance representative, who can explain exactly what is needed to ensure continuous and adequate coverage, both during and after the renovation.
