This step must be done carefully to avoid further damage.Structural Repairs: Address any structural damage first, including the roof, walls, and foundation.Systems Repair: Repair or replace electrical, plumbing, and HVAC systems as needed.Interior Restoration: Once the structural and system repairs are complete, focus on restoring the interior, including insulation, drywall, flooring, and fixtures.Safety and Health Concerns:Air Quality: Ensure proper ventilation and air quality during and after the restoration process to remove smoke odors and contaminants.Mold Remediation: Check for and address any mold growth, which can be a common issue in fire-damaged properties due to water used in firefighting.Final Inspections:City Inspections: Coordinate with the city for final inspections to ensure that the property is safe and habitable.Fire Department Clearance: Obtain clearance from the Fire Department confirming that the property is safe to occupy.I hope this helps, best of luck!
