Why Do Renovation Costs Always Go Over Budget?
Short answer: Hidden problems and scope creep.
The most common cost overruns:

4. Professional fees people forget ($15,000 to $25,000)

Should I Renovate or Move?
This depends on your situation. Here’s how to decide:
Renovate makes sense when:
- You love your location and neighbours
- Local schools work for your family
- Your section size and orientation are ideal
- Renovation costs 60% to 80% of moving costs
- Your mortgage rate is better than current market rates
Moving makes sense when:
- Renovation costs exceed 80% of buying a new home
- Your section has serious limitations (flooding, access, size)
- You need to change locations for work or family
- The local market has declined
- Renovation would over-capitalize for the area
Quick cost comparison:
Renovation total costs:
- Construction: $300,000 to $500,000
- Professional fees: $24,000 to $50,000
- Temporary accommodation: $10,000 to $20,000
- Landscaping and extras: $15,000 to $35,000
- Total: $349,000 to $605,000
Moving total costs:
- Real estate agent fees (2.5% to 4%): $20,000 to $40,000 on $800k sale
- Legal fees (sale + purchase): $3,000 to $6,000
- Moving costs: $2,000 to $8,000
- New home purchase price difference: $200,000 to $400,000
- Mortgage break fees: $5,000 to $15,000
- Total: $230,000 to $469,000
The financial tipping point: If your renovation will cost more than 70% of the price difference between your current home and your ideal new home, moving often makes better financial sense.
The emotional factors nobody talks about:
- Stress of living through construction (3 to 12 months)
- Disruption to family routines and work
- Decision fatigue from thousands of choices
- Relationship strain (renovation is a top marriage stressor)
Some homeowners thrive on renovation projects. Others find the stress unbearable. Be honest about which type you are before committing to a major renovation.
How Do I Choose a Builder for My Renovation?
Five questions to ask before hiring:
1. “How many similar projects have you completed in the last 2 years?”
Look for builders who specialize in your project type. A builder who does mostly new builds may struggle with renovation surprises.
2. “What’s included in your quote and what’s extra?”
Get specific about:
- Consent and engineering fees
- Waste removal and site cleanup
- Temporary weather protection
- Project management fees
- Allowances for fixtures and fittings
3. “What was your last project’s final cost vs the original quote?”
Honest builders will tell you about overruns and why they happened. If they claim every project comes in exactly on budget, they’re either lying or their quotes have huge padding.
4. “How do you handle variations and changes?”
Understand the process before you need it:
- Written approval for all changes
- Clear pricing for variations
- Timeline impact assessment
- Updated quotes within 48 hours
5. “Who will be on site daily and how do I contact them?”
You need direct access to the project manager, not the company office. Daily communication prevents small problems becoming expensive disasters.
Red flags to watch for:
- Pressure to sign immediately
- Reluctant to provide references
- Lowest quote by more than 20% (they’re missing something)
- Vague scope of work
- No written contract or terms
- Asking for large upfront payments (30%+ before starting)
Green flags that indicate quality:
- Detailed written quotes with inclusions and exclusions
- References you contact
- Licensed building practitioner credentials
- Professional indemnity insurance
- Membership in Master Builders or similar
- Clear contract with payment schedule tied to milestones
Frequently Asked Questions
How much should I budget for unexpected costs in a renovation?
Budget 10% to 15% above your builder’s quote for standard renovations. Add 15% to 25% for homes built before 1980. Older homes hide problems like outdated wiring, asbestos, rotten framing, and foundation issues. You won’t know what’s there until walls come down. A $300,000 renovation needs a $30,000 to $45,000 contingency fund.
Do I need council consent for all renovations in New Zealand?
No. Simple cosmetic work (painting, new carpet, kitchen cabinet replacement) doesn’t need consent. You do need consent for structural changes, plumbing alterations, electrical work, room additions, or changes affecting the building envelope. Check with your local council before starting. Working without required consent costs you $30,000+ in fines and remediation.
How much does it cost to add a second bathroom to my home?
Adding a complete new bathroom costs $25,000 to $45,000 including plumbing connections, waterproofing, tiling, fixtures, and ventilation. This assumes you have space available and reasonable access to existing plumbing. If you need to build an addition to create space, add $50,000 to $80,000 for the room construction plus the bathroom fit-out.
What’s the typical payment schedule for a renovation project?
Standard schedules are: 10% deposit on contract signing, 30% when materials arrive on site, 30% at halfway completion, 20% at practical completion, 10% after final inspection and consent. Never pay more than 50% before work is half done. Never pay the final amount until all defects are fixed and code compliance certificate is issued.
Can I live in my home during a major renovation?
This depends on scope. Kitchen or bathroom renovations let you stay home with some inconvenience. Full house renovations or structural work often require moving out for safety and access. Budget $10,000 to $20,000 for temporary accommodation during major projects. Your builder needs clear access without working around your daily routines.
How do I know if my renovation will add value to my home?
Kitchen and bathroom renovations return 70% to 85% of costs at resale. Adding bedrooms or bathrooms returns 60% to 75%. Converting garages or adding second stories returns 50% to 65%. Compare your post-renovation value to similar homes in your area. If your renovation pushes your home 20% above neighbourhood average, you’ve over-capitalized and won’t recover costs.
