Building code compliance refers to the conformity of a building's design, construction, and ongoing maintenance with applicable national and local building codes. Every country maintains its own building code framework, such as the International Building Code (IBC) and International Residential Code (IRC) widely adopted across the United States, the National Building Code of Canada, or the Building Regulations in the United Kingdom. These codes set the minimum required level of safety, health, amenity, accessibility, and sustainability for new buildings and alterations. Local authorities enforce compliance through the development approval, permitting, and building certification process.
How Building Codes Work
Building codes provide a uniform set of technical provisions for the design and construction of buildings and structures. They are updated regularly to reflect changes in technology, building practices, and community expectations. Most codes separate requirements for residential and commercial buildings, each with specific performance requirements. In the US, codes are adopted at the state or municipal level; in other countries, a single national code may apply with local variations.
Common Compliance Issues
Non-compliance with building codes is a frequent finding in property inspections. Common issues include inadequate smoke alarm installations, non-compliant balustrades and pool fencing, unapproved building work such as enclosed carports or converted garages, and missing or incorrect waterproofing in wet areas. These issues can create safety hazards, affect insurance coverage, and complicate property transactions.
Compliance in Existing Buildings
Building codes primarily apply to new construction and major renovations, so existing buildings may not meet current code requirements. Building inspectors assess the condition of existing buildings against the standards that were applicable at the time of construction, while noting any items that present a current safety risk regardless of when the building was constructed.
Role of Building Inspectors
Building inspectors identify code compliance issues during pre-purchase inspections, progress inspections of new builds, and defect assessments. Their reports help buyers, owners, and builders understand the compliance status of a property and prioritise any rectification work.
