Illinois experiences a continental climate with cold, snowy winters and warm, humid summers, necessitating materials that can withstand significant temperature and humidity variations. For bathroom additions, this means prioritizing robust waterproofing membranes, moisture-resistant drywall, and durable tile with high-performance grout. Proper insulation and ventilation are critical to prevent condensation and potential mold growth, particularly in newly constructed spaces. The permitting process in Illinois, while generally standardized, can vary by municipality, with Chicago having particularly detailed requirements for plumbing and electrical work. Homeowners should consult local building departments to ensure all necessary permits are obtained before commencing work. The housing stock in Illinois is varied, ranging from vintage Chicago bungalows and historic homes to modern suburban residences, each presenting unique challenges regarding existing plumbing and electrical infrastructure that must be addressed during an addition.
