CertOne Building Certifiers

Residential building projects require careful attention to approvals, construction standards and regulatory compliance. At CertOne Building Certifiers, we help clients throughout Greater Sydney and NSW manage these responsibilities through independent private certification services. Our qualified team works alongside property owners, construction professionals and project consultants, providing guidance at each stage of the certification process. We assess applications for Complying Development Certificates and Construction Certificates, undertake required construction inspections and issue Occupation Certificates once the relevant conditions have been satisfied. Swimming pool safety assessments and Pool Compliance Certificates also form part of our service offering. For existing residential work completed without approval, we prepare BCA Reports that examine applicable National Construction Code requirements and highlight matters requiring attention.

Our approach places particular importance on efficiency, technical accuracy and consistent communication. Advanced inspection equipment, including drones and thermal imaging cameras, helps us document building conditions and identify concerns that may not be immediately visible. Homeowners dealing with council compliance correspondence can receive practical assessments of unauthorised renovations, additions and other relevant residential structures. We also provide independent compliance consultations when our appointment as certifier is not required. Supported by experienced professionals, industry memberships and modern reporting technology, we offer clear advice, responsive assistance and free fee proposals to help clients understand their certification requirements.
