The 1% Rule: Your Starting Point
A widely accepted guideline is allocating 1% of your building’s replacement value annually for maintenance and capital works.
Example: Building replacement value $30 million = $300,000 annual budget (split: $150,000 operational + $150,000 sinking fund)
However, adjust this baseline for:
- Building age: Under 10 years (0.5-0.75%), 10-20 years (0.75-1.25%), Over 20 years (1-2%)
- Location: Coastal properties add 20-30% for salt exposure
- Known issues: Combustible cladding, concrete cancer, aging systems add 0.2-0.5%
Sample Annual Budget: Medium Strata Building
60-unit, 8-storey building, 18 years old, Melbourne eastern suburbs
Replacement value: $25 million
Recommended allocation: $250,000-$350,000 annually
| Item | Frequency | Annual Cost |
|---|
| Facade cleaning | Annual | $15,000-25,000 |
| Window cleaning | Quarterly | $12,000-18,000 |
| Common area cleaning | Weekly | $25,000-35,000 |
| Building insurance | Annual | $35,000-50,000 |
| Strata management | Monthly | $18,000-25,000 |
| Lift maintenance | Annual | $15,000-22,000 |
| Building manager | Annual | $60,000-80,000 |
| Routine repairs | As needed | $15,000-25,000 |
| Sinking fund | Annual | $50,000-80,000 |
| TOTAL | | $245,000-$360,000 |
Major works to plan (5-10 years):
- Complete facade repaint: $250,000-400,000 (every 10-15 years)
- Concrete cancer remediation: $150,000-350,000 (as required)
- Waterproofing renewal: $120,000-200,000 (every 12-18 years)
Sinking Fund vs. Capital Works Fund — What’s the Difference?
You’ll see both terms used for the same basic idea: money set aside for major, non-routine works rather than day-to-day maintenance. “Sinking fund” is the older, more commonly used term across Victoria and most states; “capital works fund” is the updated terminology used in some jurisdictions’ strata legislation. For budgeting purposes, treat them as the same line item — the important number is how much is going in each year, not which name your building uses.
As a starting point, most Melbourne strata buildings should be allocating an additional 0.5–1% of the building’s replacement value annually into this fund, on top of routine maintenance spending — see the sample budget above for how that splits out in dollar terms.
Common Maintenance Costs 2026
Facade & External Work
Facade Cleaning: $15-30 per linear metre (rope access annual clean)
Window Cleaning: $3-6 per window per visit
Facade Painting: $50-120 per square metre
Sealant Replacement: $60-150 per linear metre
Example: 8-storey building, 120m perimeter facade cleaning = $18,000-36,000 annually
Concrete Repairs
Concrete Cancer Repair: $300-800 per square metre
Balcony Concrete Restoration: $5,000-12,000 per balcony
Structural Repairs: $500-1,500 per square metre
Example: 15 sqm balcony edge repair = $7,500-12,000
Waterproofing
Balcony Waterproofing: $150-250 per square metre
Roof Waterproofing: $100-180 per square metre
Basement/Car Park: $150-300 per square metre
Example: 8 sqm balcony waterproofing = $1,200-2,000
Cladding Work
Cladding Inspection: $5,000-15,000 comprehensive audit
Panel Replacement: $500-2,000 per panel
Combustible Cladding Rectification:
- Small building (20-40 units): $800,000-2,000,000
- Medium building (40-100 units): $2,000,000-5,000,000
- Large building (100+ units): $5,000,000-15,000,000+
CSV funding may cover 50-100% for eligible buildings.
Building Systems
Lift Maintenance: $12,000-18,000 per lift annually
Fire Safety Testing: $3,000-8,000 annually
BMU Service: $15,000-30,000 annually
Melbourne-Specific Considerations
Combustible Cladding Crisis
Buildings constructed 2000-2018 with aluminium composite panel cladding face significant rectification costs in 2026.
Budget Requirements:
- Assessment and testing: $8,000-20,000
- Rectification: $1,500-3,500 per square metre of cladding
- 80-unit building example: $3.2 million total, potentially $1.2 million after CSV funding = $15,000 per unit
Annual planning allowance: $20,000-50,000 for assessment and CSV application preparation
Coastal Corrosion
Bayside Melbourne properties (St Kilda, Brighton, Sandringham) face accelerated deterioration:
Additional costs:
- Facade cleaning every 6 months vs annually (double cost)
- Concrete cancer appears 5-10 years earlier
- Metal component corrosion accelerated
- Total coastal premium: Add $50,000-150,000 annually for medium buildings
Planning for Major Works
When Special Levies Are Necessary
Special levies are required when sinking funds are insufficient for combustible cladding rectification, emergency repairs exceeding reserves, unexpected major defects, or compliance orders.
Example scenario: $2 million concrete remediation, 60 units
- Option A: Immediate special levy = $33,333 per unit
- Option B: 5-year strata loan at 8% = $605 per unit quarterly
- Option C: Hybrid approach balancing immediate impact with manageable payments
Staged Approaches
When budgets are constrained, prioritise strategically:
Critical (0-12 months): Safety hazards, active water damage, fire safety
High Priority (1-3 years): Advancing concrete cancer, coating failures
Medium Priority (3-5 years): Preventative maintenance, system upgrades
Low Priority (5+ years): Aesthetic improvements, optional upgrades
Example staged plan:
- Year 1: Emergency balcony repairs – $180,000
- Year 2: Waterproofing renewal – $220,000
- Year 3: Facade preparation – $150,000
- Year 4: Complete painting – $280,000
- Year 5: Remaining works – $200,000
Total $1,030,000 spread over 5 years vs single special levy
Red Flags Requiring Budget Increases
Immediate action needed if you notice: visible concrete spalling or rust staining; water stains below balconies; paint peeling extensively; sinking fund below 50% of planned works; special levies required more than once per 5 years; or insurance premiums increasing 20%+ annually.
Preventative vs Reactive Costs
Preventative maintenance costs 60-70% less than emergency repairs.
Example: Balcony waterproofing
- Preventative (regular maintenance, renewal at 10 years): $15,300 over 10 years
- Reactive (failure, damage, emergency work): $53,000
- Savings: $37,700 (71%)
Building Your Budget: Quick Steps
- Determine replacement value: Engage quantity surveyor or use insurance valuation
- Apply base percentage: Start with 1%, adjust for age/location/issues
- Split operational vs capital: Typically 40% operational, 60% sinking fund
- Detail operational costs: Cleaning, insurance, management, repairs
- Plan capital works: Identify major works needed next 10 years
- Review quarterly: Track actual vs budget, adjust as needed
Conclusion: Protect Your Investment
Effective strata budgeting balances property protection, owner costs, and resident safety. Buildings maintaining their value best have realistic budgets, healthy sinking funds, preventative maintenance programs, and long-term capital works planning.
Melbourne’s strata buildings in 2026 face significant challenges: aging building stock, combustible cladding rectification, coastal corrosion, and increasing compliance expectations. Realistic budgeting and proactive maintenance have never been more important.
