In Illinois, constructing an accessory dwelling unit (ADU) requires compliance with both state building codes and local municipal ordinances, which can differ significantly in areas like Rockford. Common regulations involve minimum lot sizes, setback requirements from property lines, and limits on the ADU's square footage relative to the main house. We ensure your project meets all these local mandates. The expense of building an ADU is influenced by its size, architectural complexity, and the selection of materials. Site preparation, including any necessary excavation, utility extensions, and foundation work, also contributes to the overall cost. We perform a comprehensive site evaluation to detail these factors.
