1. Building Consent Requirements
- Exempt Work: Minor updates (replacing taps, vanities, or tiles without structural changes) typically do not require consent.
- Consent Required: For structural changes (moving walls), plumbing/drainage alterations, or relocating fixtures (shower, toilet). Electrical work must be done by a licensed electrician.
- Auckland-Specific: Check the Auckland Unitary Plan for heritage or zoning restrictions. Apartments may need body corporate approval.
2. Relevant Building Codes (NZBC)
- E3 Internal Moisture: Ensures waterproofing (e.g., waterproof membranes in showers).
- G13 Foul Water: Proper waste drainage and venting.
- B2 Durability: Materials must withstand moisture long-term.
- H1 Energy Efficiency: If adding/altering windows.
3. Cost Estimates
- Basic Refresh: $10,000–$20,000 (fixtures, tiles, no structural work).
- Mid-Range: $20,000–$30,000 (moving plumbing, new layout).
- High-End: $30,000+ (luxury finishes, structural changes).
- Additional Costs: Consent fees (~$2,000), design/engineer fees, and potential unforeseen issues.
4. Timeline
- Consent-Exempt: 1–3 weeks (simple updates).
- Consent Required: 2–3 months (20 working days for council approval, plus construction). Delays may occur due to council queries or material shortages.
5. Key Considerations
- Compliance: Even exempt work must meet NZBC standards (e.g., waterproofing).
- Professionals: Use licensed plumbers, electricians, and builders.
- Consultation: Contact Auckland Council for specific advice or engage a professional (e.g., architect) for complex projects.
Always verify plans with the Auckland Council or a building consultant to ensure compliance with local rules.
