Overview
Retrospective building approval is the process of certifying structures that were built without prior approval. This ensures that your existing building work meets all current building codes and regulations.
- Legal Compliance: Ensures your structures comply with national construction codes.
- Insurance Coverage: Many insurance policies require all structures to be approved to maintain coverage.
- Property Value: Approved structures are recorded with the council, avoiding issues during property sales or council inspections.
- Peace of Mind: Knowing your structures are safe and compliant offers significant peace of mind.
