Peel builders and real estate agents say they expect a wave of home building and renovation work to hit the region in the coming months.
The reports come following the state government announcing a $20,000 cash grant to anyone building a new home, including properties in a development under construction.
The grant - which is valid until the end of the year - is in addition to the federal government's $25,000 grant announced a few days earlier and the existing $10,000 WA first home owner grant and stamp duty concession.
That means someone who qualifies for all four grants could access almost $70,000 in government assistance to help build their first home.
Raine and Horne Mandurah principal Peter Vetten said land sales had increased since the federal government's Homebuilder package was introduced last week.
"We have definitely had a lot more activity in our land sales and our enquiries for land have increased a lot," he said.
"Land over 2000sqm seems to be the most popular option at the moment as that is really kicking along very strongly."
With land sales already increasing, the grants are set to create jobs for builders and tradies in the Peel region.
A survey by Master Builders Association of WA found 70 per cent of businesses had at least a 40 per cent decline in their pipeline of work.
Housing Industry Association WA executive director Cath Hart said WA would be hit first by the country's building downturn because it had "the shortest project pipeline of all states".
But with the help of the stimulus packages, Mandurah Homes supervisor Todd Green said he had received six to seven enquiries per day since the $20,000 grants were announced on Monday.
"It is definitely going to create more jobs for the local subcontractors out there and the local builders in town."
Great Living Homes is another Mandurah-based building company seeing "the light at the end of the tunnel".
"The industry feels a lot more positive, that's for sure," estimator Daniel Ayres said.
"There is far more interest in building and when people are enquiring it's not just curiosity but genuine interest with more of a push to get things through quickly."
