Productivity Commission Housing Supply Report 2026: What It Says and What Has Not Changed

Short summary

The Productivity Commission released its housing supply regulation interim report on 27 July 2026. It identifies land-use controls and the coordination of housing-enabling infrastructure as the reform areas most likely to improve housing supply and affordability.

This is an interim report, not a new planning law. It does not change zoning, development approval rules, first home buyer support, lending policy or any RealEstateCalc formula today.

The Commission is seeking feedback by 30 September 2026. Its final report is due to the Australian Government in March 2027.

What the interim report says

The inquiry is examining how regulation across all levels of government can support more well-located housing and faster delivery.

The interim report sets out four principles for a better housing regulatory system:

1. adopt a build mindset;
2. regulate only where necessary;
3. coordinate housing with infrastructure; and
4. keep processes simple.

The Commission says relaxing land-use controls and coordinating enabling infrastructure are likely to have the greatest effect. It also identifies slow and complex approvals as a contributor to delay, while noting that approval reform alone will not solve the supply problem.

The land-use changes being considered

The report asks governments to consider broad changes rather than relying only on selected precincts. Options include:

• allowing three-storey development on most residential land;
• reducing minimum lot sizes;
• permitting more mixed residential and commercial areas;
• allowing more mid-rise and high-rise apartments in high-demand, well-serviced locations; and
• making simple developments easier to assess through suitable fast-track pathways.

These are reform areas for consultation. The report does not itself amend a local environmental plan, planning scheme or building approval process.

The practical effect would depend on what each government later adopts, where it applies, infrastructure capacity, development feasibility and the time required to bring completed homes to market.

Why infrastructure is part of the housing question

Rezoning land does not make it ready for a home by itself. Roads, public transport, water, sewerage, electricity and community infrastructure may need to be funded, sequenced and delivered before construction can proceed.

The Commission says housing and infrastructure plans should be better aligned. It also calls for clearer funding and sequencing and more consistent coordination across governments, councils and utility providers.

That distinction matters when reading a supply announcement. Land identified for housing is not the same as:

• development-approved lots;
• serviced lots;
• dwellings under construction; or
• completed homes available to buy or rent.

The 11-year deposit figure

The Commission says it now takes the average household around 11 years to save a 20% deposit on a typical home, compared with eight years in 2005.

That figure describes a national affordability trend. It is not a forecast for an individual buyer.

A personal deposit timeline changes with:

• the target property price;
• the deposit percentage;
• starting savings;
• regular contributions;
• interest earned;
• purchase costs such as transfer duty, conveyancing and inspections; and
• any movement in the target price while saving.

For example, a 20% deposit on an $850,000 property is $170,000 before buying costs. A buyer with $45,000 saved still has a $125,000 deposit gap. Saving $2,500 a month would close that gap in 50 months if the target, contribution and interest assumptions did not change.

Real life rarely holds every input constant. The target property price may move, savings interest may change and purchase costs need their own allowance. Use the Deposit Savings Calculator for a scenario, then run the Property Purchase Cost Calculator separately.

What this means for buyers and owners now

The report can help users understand the policy discussion, but it should not be used to predict a property price or time a purchase.

Current buyers should still check:

• the planning controls that apply to the specific site now;
• the approved use and development potential rather than an untested assumption;
• current infrastructure and service constraints;
• the contract and title with a conveyancer or solicitor;
• current finance and repayment scenarios; and
• current state taxes, grants and concessions with the relevant authority.

A proposed upzoning should not be treated as a valuation. A future supply response may also differ materially between suburbs and dwelling types.

Calculator and content impact

No calculator formula changed after the interim report.

The report does not provide:

• a new deposit percentage;
• a new lending serviceability rule;
• a transfer duty threshold;
• a first home buyer eligibility rule;
• a reliable property growth assumption; or
• a construction cost input that can be applied nationally.

Use the Mortgage Repayment Calculator to test a loan amount and interest rate entered by the user. Use the Borrowing Power Calculator only as a general scenario tool, not as a prediction of lender approval or future housing policy.

What happens next

Post-interim submissions are due by Wednesday 30 September 2026. The final report is due to the Australian Government in March 2027.

The final report may differ after consultation. Government responses, legislation and state or local implementation would be separate later steps.
