HIA Tasmania Executive Director Benjamin Price said granny flats are one of the quickest and most sensible ways to boost housing supply, particularly in established suburbs close to jobs, schools and services.
“Bigger granny flats mean bigger choice, and lifting the size limit helps get unnecessary regulation out of the way of sensible housing options,” Mr Price said.
“This change gives homeowners and builders the flexibility to build a genuinely usable second home that meets real market demand.”
Mr Price said the national experience showed exactly what happens when planning barriers are removed.
“Nationally, granny flat construction has surged, with HIA analysis showing members expect to build around ten times more granny flats this year than they did in 2022,” he said.
“Too often pointless red tape gets in the way of sensible housing choices, and this change clears a path for more homes to actually get built.
“With land supply constrained and construction capacity under pressure, we need to make better use of the land we already have. Granny flats do exactly that.”
Mr Price said increasing size limits made granny flats far more practical for renters, downsizers and multigenerational families, while also supporting local builders and tradies.
“Larger granny flats mean more choice for families, more rental supply, and more work flowing through the residential building sector,” he said.
“If we’re serious about housing supply, then freeing up infill opportunities is simply common sense.”
Mr Price said Tasmania was now well placed compared to other states.
“At 90 square metres, this puts Tasmania at the very top end nationally for granny flat size, giving families and builders flexibility you simply don’t see in most other states.”
HIA said granny flats should be treated as a core part of the housing solution and called on governments to continue removing barriers that slow small scale, shovel ready projects.
“The fastest way to deliver more homes is to let people build them where infrastructure already exists,” Mr Price said.
“Granny flats are a practical, low impact way to do exactly that.”

Member information: Fuel Surcharges and the Road Transport Order
In April 2026 an order requiring primary and secondary parties in road transport contractual chains to review and adjust transport rates fortnightly to recover increased fuel costs was handed down by the FWC. This requirement switched off automatically in the week ending 5 June 2026, when the weekly average national terminal gate diesel price fell below $2.00 per litre but did not revoke the order. HIA breaks down what this means for your business.
Superannuation Legislation Amendment (Fair Super for Young Workers) Bill 2026
HIA supports fair treatment of young workers and recognises the importance of appropriate superannuation coverage. However, HIA opposes the Bill as drafted due to a number of legal and technical issues, primarily the impact on small business builders.

National Tradies Day - Tradies will build Tasmanias future
Tasmania's home builders have marked National Tradies Day by putting the case for a trade career to young Tasmanians, saying the trades offer one of the strongest pathways in the state to secure work, real money from day one, and a career that technology is far more likely to help than replace.
