Residents of a village with a population of about 1,000 are to vote in a community poll on proposals for up to 2,000 extra homes.
People in Bodwelwyddan will make their views heard on whether Denbighshire council should proceed with its local development plan to treble its size.
Opponents say that is unsustainable, and want a smaller development.
The poll will be on 7 January but the council has said the result will not be "binding".
The proposals could also see a new primary school, care home and new access from the A55.
However, there has been local opposition, and the Bodelwyddan Development Action Group has held a series of public meetings.
Its founder, Alice Jones, has said the proposals include building 1,715 new houses, and that the current population could rise to 6,000 over 12 years.
The council has confirmed that, following requests from residents, a community poll will be held.
Residents registered as voters in Bodelwyddan will be allowed to vote on one question: "Should Denbighshire County Council continue with the proposed development plan for Bodelwyddan?"
In a fact sheet available to voters, the council said: "The outcome of the poll is no more and no less than an expression of the views of the electorate of the community who have voted in the poll and is not binding on any body."
The poll will be held between 1600 GMT and 2100 GMT on 7 January at the community centre on Ty Fry Lane.
