Integrating dampness control into Ghana’s building regulations: lessons from global codes

Moisture intrusion continues to threaten building durability and occupant health, particularly in tropical regions such as Ghana. This study examines how leading international building codes, that is, the United States’ International Building Code and International Residential Code, the United Kingdom’s Approved Document C, the Canadian National Building Code, the Australian National Construction Code, and Germany’s DIN 4108/EPBD, address moisture management, and compares these provisions with Ghana’s Building Code (GS 1207:2018). A qualitative, descriptive, and comparative research design was adopted, supported by systematic documents analyses. Clauses related to damp-proofing, waterproofing, ventilation, and condensation control were extracted, organised into five thematic areas, and analysed using content and comparative techniques to identify regulatory patterns and enforcement mechanisms. A cross-comparison matrix highlighted areas of convergence and divergence, and manual thematic coding supported the synthesis of findings. Results show that international codes employ integrated, performance-based, and climate-responsive approaches that link moisture control to durability, energy efficiency, and occupant well-being. Conversely, Ghana’s code remains largely prescriptive, fragmented, and limited in technical depth and enforcement detail. Key gaps include inadequate condensation control, absence of material certification requirements, and weak inspection protocols. The study proposes performance-oriented, climate-specific, and verifiable reforms to strengthen Ghana’s regulatory framework.
