A builder in NSW is applying for a DA and CC on a $480,000 new house build. Before the development application goes in, they need an estimate of council fees, the Long Service Levy and inspection costs so the client can budget the full upfront outlay.
Construction Permit Cost Estimator
Permits
Estimated total cost of the build or renovation
AU (Development Approval + Construction Certificate): DA fee (based on construction value), Construction Certificate fee, Inspection fees, Long Service Levy (0.35% of contract value in NSW), Section 7.11 contributions (for new builds). Total typically 1.5–3% of construction value.
US (Building Permit): Base permit fee + plan review fee. Ranges from $500 (simple reno) to $5,000+ (new build). California typically 2–5% of project value.
Always verify with your local council / building department — fees vary significantly.

1 What this calculator does
Estimates Australian council permit fees (DA, CC) and the NSW Long Service Levy, or US building permit fees, from the construction value, project type and state/location. Shows each fee component separately. All figures are estimates -- always verify with the local council or building department.
2 Formula & professional reasoning
AU DA fee (approximate):
Under $100K: value x 0.5% + $250
$100K-$1M: $750 + (value - $100K) x 0.25%
Over $1M: $3,000 + (value - $1M) x 0.10%
AU CC fee (construction certificate): ~80% of DA fee
NSW Long Service Levy: value x 0.35%
Inspection fees (approx): $600
US permit fees: value x 1.0-2.5% (state-dependent) + plan review (~65% of permit fee)
Australian council fees are calculated on a sliding scale based on the construction value -- lower percentage rates apply to larger projects, reflecting economies of scale in council administration. The Construction Certificate (issued by a private certifier or council) confirms the design complies with the Building Code before construction begins. The NSW Long Service Levy funds portable long service leave entitlements for construction workers in NSW. All of these fees are payable before construction starts and must be funded from the owner's equity or construction loan.
3 Worked examples
⚠️ Illustrative example only — not clinical or professional instruction.
Basic
New house in NSW -- DA, CC and Long Service Levy
Given: Construction value: $480,000 | Type: new house | State: NSW
Working:
DA fee: $750 + ($480K - $100K) x 0.0025 = $750 + $950 = $1,700 | CC fee: $1,700 x 0.80 = $1,360 | LSL levy: $480,000 x 0.0035 = $1,680 | Inspection fees: $600 | Total: $1,700 + $1,360 + $1,680 + $600 = $5,340Answer: Estimated total permit and levy costs: $5,340 (~1.1% of construction value)
💡 Permit costs for a standard new residential home in NSW typically run 1.0-1.5% of the construction value. This does not include Section 7.11 development contributions (infrastructure levies) which can add $5,000-$30,000+ for new residential subdivisions.
Standard
Commercial extension in Victoria
Given: Construction value: $1,200,000 | Type: extension/renovation | State: VIC
Working:
DA fee (VIC planning permit approx): $3,000 + ($1.2M - $1M) x 0.001 = $3,000 + $200 = $3,200 | CC fee (building permit VIC): $3,200 x 0.80 = $2,560 | No LSL levy for VIC | Inspection fees: $1,200 | Total: $6,960Answer: Estimated permit costs: ~$6,960 (~0.6% of construction value)
💡 Large commercial projects have lower permit fee rates as a percentage of value. VIC does not have the NSW Long Service Levy structure -- but VIC Building Permit Levy applies at 0.128% of permit value for building work over $10,000. Always verify with the relevant council.
Advanced
US new build permit in California
Given: Construction value: $800,000 | State: California (2.5% rate)
Working:
Permit fee: min($500, max($800K x 0.025, $50K)) = min($20K, $50K cap) = $20,000 | Plan review: $20,000 x 0.65 = $13,000 | Inspections: $800 | Total: $33,800Answer: Estimated US permit costs (California): ~$33,800 (~4.2% of construction value)
💡 California has some of the highest building permit costs in the US. California cities (LA, SF, San Jose) add additional fees. The 2.5% rate is an average -- actual rates vary significantly by municipality.
4 Sanity check
AU permit costs as % of construction value (approximate)
New house $500K: 1.0-1.5% | Commercial $1M: 0.5-1.0% | Renovation $200K: 1.5-2.5%
Smaller projects pay a higher % of value in permit fees because fixed minimums are a larger share.
NSW Long Service Levy (2024)
0.35% of the contract price for building work over $25,000 | Payable before the CC or CDC is issued
The LSL levy is remitted to the NSW Long Service Corporation -- verify the current rate at longservice.nsw.gov.au.
What is NOT included
Section 7.11 development contributions (infrastructure levies) -- can be $5K-$50K+ for new residential | Basix certificate fee | Heritage impact assessment | Acoustic or flood reports
US permit costs as % of construction value
National average: 1.0-1.5% | California: 2.0-2.5% | Texas: 0.5-1.0% | New York: 1.5-2.0%
5 Common errors
| Error | Cause | Consequence | Fix |
|---|---|---|---|
| Not budgeting for Section 7.11 (NSW) or equivalent developer contributions | Treating permit fees as the only council cost for new residential construction | Significant unexpected cost at the DA approval stage -- Section 7.11 contributions can exceed $30,000 in some councils | Ask the council's planning team or a town planner about applicable Section 7.11 (NSW) or Section 94 contributions before lodging the DA. These infrastructure levies vary enormously between councils and are payable before construction commences. |
| Not including council permit costs in the construction loan budget | Treating permit fees as separate to the project budget | Insufficient funds to pay permit fees before construction can start -- delaying the project | Permit fees are payable before construction begins and must be funded from available cash or the construction loan draw. Include all permit and levy costs in the total project budget presented to the lender. |
| Using a previous project's permit fees without adjusting for the new project value | Assuming permit fees are fixed | Permit cost estimate wrong -- fees are indexed to the construction value | Permit fees scale with the construction value. Always recalculate from the current project's contract value using the sliding scale formula or the council's fee schedule. |
| Not verifying that the quoted permit fee is current | Using fee tables from a prior year | Permit fees change with council budgets and state legislation -- actual cost may be 10-20% higher | Always verify the current fee schedule with the local council or state government fee calculator before lodging a DA or building permit application. In NSW, use the IPART housing fees calculator. |
