NCC 2025 + RBA 5 May: What Victorian Builders Fund Differently
Three cost-of-finance events land within seven days for Victorian builders: NCC 2025 goes mandatory on 1 May, the RBA announces its next rate decision on 5 May, and the March quarter CPI drops on 29 April. Each one shifts what you need to fund and how lenders read your feasibility.
Quick Answer
Victorian builders should lock development finance terms before the first week of May, when NCC 2025 compliance costs become mandatory and the RBA is widely expected to raise the cash rate again.
Three Events, Seven Days, One Cost Stack
Victoria's construction cost environment is about to shift in a single week. The RBA's 17 March 2026 decision (effective 18 March) lifted the cash rate to 4.10% — the second consecutive hike — and all four major banks are tipping another 25 basis point increase at the 5 May meeting, which would push the rate to 4.35%, matching the November 2023 peak that was held from November 2023 to February 2025 before the 2025 cutting cycle began.
Sandwiched between the rate decision and NCC 2025's Victorian start date is the March quarter CPI release on Tuesday 29 April at 11.30 am AEST. This is the quarterly figure — distinct from the monthly indicator already out at 3.7% to February — and it is the number the RBA actually weights for policy. If the quarterly print comes in hot, the 5 May hike becomes almost certain. If it softens, there is still an outside chance the Board holds.
Then on 1 May, Victoria becomes the first state to make NCC 2025 mandatory. New building approvals from that date must comply with updated waterproofing, ventilation, lead-free plumbing, energy efficiency (Section J), and on-site solar PV requirements for commercial Class 3 and 5–9 buildings. Master Builders Victoria described the timing as "extremely disappointed" — builders absorb higher compliance costs at the same time as higher borrowing costs.
Tuesday 29 April — March quarter CPI release
ABS publishes the quarterly CPI at 11.30 am AEST. This is the swing factor for the RBA's 5 May decision. Builders with pending feasibility sign-offs should have their QS numbers locked before this date — a hot print could shift lender appetite within hours.
Thursday 1 May — NCC 2025 mandatory in Victoria
All new building approvals in Victoria must comply with NCC 2025 from this date. Lead-free plumbing, balcony waterproofing, ventilation upgrades and commercial solar PV requirements add to the cost stack on every new project. NSW and QLD have deferred to 1 May 2027 with voluntary early adoption from 1 May 2026. The ACT has a 6-month voluntary transition window from 1 May to 1 November 2026.
Monday 5 May — RBA rate decision (2.30 pm AEST)
The Board meets 4–5 May. Markets and all four major banks are pricing a hike to 4.35%. Every 25 basis points adds to capitalised interest on staged drawdowns — on a $2 million development facility drawn over 12 months, that is roughly $5,000 in additional interest cost (illustrative, varies by lender and draw schedule).
What NCC 2025 Adds to a Victorian Builder's Cost Stack
NCC 2025 is not a single cost line — it is a set of compliance upgrades that land across different trades and different project types. The impact on your gross realisation value depends on what you are building and where.
For residential builders doing townhouse or duplex projects, the main cost additions are lead-free plumbing fittings (copper alloys capped at 0.25% weighted average lead for drinking water contact), stronger ventilation to prevent condensation and mould, and mandatory waterproofing on balconies, podiums, and carparks in apartment buildings. These are not optional upgrades — they are conditions of building approval from 1 May in Victoria.
For commercial builders (Class 3, 5–9), the bigger ticket is Section J energy efficiency — up to a 50% cap reduction on energy allowances — plus mandatory on-site solar PV under the new J9D5 requirement and open-deck carpark sprinkler requirements. These push the total development cost higher, which means your quantity surveyor needs to remodel feasibility inputs before you submit for development approval.
Victoria also reduced its state-specific variations from 115 to 60 under NCC 2025 — a simplification, but one that still requires builders and certifiers to reconcile the new national standard against remaining Victorian amendments. If your last feasibility was run against NCC 2022 assumptions, the cost-to-complete line has moved.
How the RBA 5 May Decision Changes Your Feasibility Numbers
A rate hike does not just increase your repayments — it changes how lenders model capitalised interest inside a development facility. Development finance is not like a standard business loan where you make regular repayments from day one. Interest accrues on each drawdown stage and capitalises until the project completes and sells or refinances.
That means every basis point increase feeds directly into the total development cost. On a $3 million facility drawn progressively over 14 months at an indicative rate of 9.5% p.a., a 25 basis point increase adds roughly $7,000–$10,000 to the total capitalised interest bill (illustrative — actual figures vary by lender, draw schedule, and project timeline). On a tight feasibility, that is the difference between a marginal approval and a decline.
If the March quarter CPI prints high on 29 April, lenders will start pricing the hike into new applications before the RBA even announces. Builders who have their feasibility, QS report, and pre-approval documentation ready before 29 April are in the best position to lock terms ahead of any repricing. Check your eligibility now to get the process moving before the CPI release lands.
The Timing Sweet Spot for Victorian Builders
The window between now and 29 April is the sweet spot for locking development finance terms. After that date, three variables move simultaneously — and all three push costs higher for builders.
Sweet Spot — Lock Before 29 April
- Submit your feasibility with updated NCC 2025 cost inputs before the March quarter CPI release on 29 April
- Get conditional approval at today's rate settings — lenders typically hold terms for 30–60 days on conditional approvals
- QS report should reflect NCC 2025 compliance costs for any project seeking building approval after 1 May in Victoria
- If your project is in NSW or QLD, you have until 1 May 2027 — but the rate environment still shifts on 5 May regardless of state
- Builders in the ACT have a 6-month voluntary transition (1 May to 1 November 2026) — plan around the November hard deadline
This is not about rushing into a facility — it is about having your documentation ready so the lender's credit team can assess your deal at current pricing. Once the CPI prints and the RBA moves, the pricing floor resets. Every development finance application submitted after 5 May will be assessed against the new rate, the new NCC cost inputs, and any updated lender risk appetite that follows.
For builders running multiple projects, the construction loan pack sequences development finance alongside commercial property loans and cashflow facilities so one approval does not cannibalise servicing on the next. The loan pack sequencing guide covers the order of operations.
What to Update in Your QS Feasibility Before 1 May
Your quantity surveyor's feasibility report is the document the lender's credit team uses to approve or decline the facility. If it was modelled before NCC 2025 inputs were available, it is already out of date for any Victorian project seeking building approval after 1 May.
Remodel cost-to-complete with NCC 2025 line items. Lead-free plumbing, waterproofing upgrades, ventilation, and (for commercial) solar PV and sprinkler requirements. Your QS should provide a line-by-line delta against the NCC 2022 baseline.
Stress-test capitalised interest at 4.35%. Model the facility at a rate 25 basis points above your current indicative quote. If the feasibility still holds at the higher rate, the approval is resilient to a May hike. Lenders will run this stress test themselves — beat them to it.
Confirm your LVR still works. Higher total development cost means your loan-to-value ratio shifts. If the cost stack has moved but the end value estimate has not, the LVR tightens. Your QS and valuer need to be in alignment before the file goes to credit.
Check whether your project can launch under NCC 2022. Projects with building approval lodged before 1 May in Victoria can still proceed under NCC 2022. If your DA is close to lodgement, the compliance cost delta may tip the decision on timing. See the development finance checklist for the full approval documentation list.
The builders who get caught are the ones who submit a feasibility built on last year's cost assumptions and last month's rate. The lender will reject it — not because the project is bad, but because the numbers do not reflect today's inputs. Update the model first. For projects without presales, see no-presales development finance for how lenders assess feasibility when there is no pre-commitment revenue. The construction hub has the full guide library for builders at every stage.
Three cost-of-finance events converge in one week for Victorian builders. NCC 2025 compliance costs go mandatory on 1 May, the March quarter CPI drops on 29 April, and the RBA is widely expected to hike to 4.35% on 5 May — matching the November 2023 peak. Each one pushes your total development cost higher. The timing sweet spot is now: get your QS feasibility updated with NCC 2025 inputs, stress-test at a higher rate, and submit for conditional approval before the CPI release resets lender pricing.
Key takeaway: The builders who lock terms before 29 April absorb one cost event at a time. After 5 May, you absorb all three at once.Frequently Asked Questions
NCC 2025 increases the cost-to-complete on Victorian projects by adding mandatory compliance items — lead-free plumbing, waterproofing upgrades, ventilation improvements, and (for commercial builds) on-site solar PV and sprinkler requirements. Lenders assess development finance applications against feasibility models, so a higher cost stack means the project margin narrows. Your quantity surveyor needs to remodel the feasibility with NCC 2025 line items before the file goes to credit. Projects with building approval lodged before 1 May 2026 can still proceed under NCC 2022.
All four major banks are forecasting a 25 basis point hike at the 5 May 2026 meeting, which would lift the cash rate from 4.10% to 4.35% — matching the November 2023 peak. The swing factor is the March quarter CPI release on 29 April. A hot quarterly print makes the hike near-certain; a softer number opens an outside chance the Board holds. For builders, the practical move is to stress-test your capitalised interest line at 4.35% regardless — if the feasibility holds, you are protected either way.
The best time is before the March quarter CPI release on 29 April 2026. Lenders typically hold conditional approval terms for 30–60 days, so an application submitted now can lock current pricing before any post-CPI repricing. After 5 May, every new application is assessed against the higher rate (if the RBA hikes), plus NCC 2025 compliance costs for Victorian projects. The window narrows further as lender risk appetite adjusts to the new cost environment. See how development finance works for the full approval timeline and staged drawdowns for how drawdown schedules interact with rate changes.
No. Both NSW and QLD have deferred mandatory NCC 2025 adoption to 1 May 2027, with voluntary early adoption available from 1 May 2026. Victoria is the only state making NCC 2025 mandatory from 1 May 2026. The ACT has a 6-month voluntary transition period from 1 May to 1 November 2026 — builders can use either NCC 2022 or NCC 2025 during that window. SA, WA, TAS, and NT adoption dates remain to be confirmed. Regardless of your state, the RBA rate decision on 5 May affects all drawdown facilities nationally, so timing your application ahead of that date still matters.
Development finance uses staged drawdowns where interest accrues on each progressive draw and capitalises until the project completes. A 25 basis point increase in the cash rate flows through to facility pricing, which means every dollar drawn accumulates interest faster. On a $2–3 million facility drawn over 12–14 months, a single 25bp hike adds roughly $5,000–$10,000 in additional capitalised interest (illustrative, varies by lender and draw schedule). That narrows your development margin, which is exactly the ratio the lender's credit team uses to approve or decline the deal. Updating your feasibility at the higher rate before submission shows the lender you have already stress-tested the project. The construction loan pack explains how to sequence development finance alongside other facilities so the total cost of capital is managed across the full project lifecycle.
