The Cairngorms National Park could become the first planning authority to introduce residency restrictions on new housing in the area.
There has been a lack of affordable housing in the park area
Under the proposals, the authority would also have planning control over plans to turn existing residences into holiday homes.
There has been a problem in the park over the lack of affordable housing.
While the number of older people is increasing, those below 40 are set to drop by 30% over the next 20 years.
The park authority's plans include a ruling that if people want to buy a new house in the park area they should already have been a resident there for at least three years, or work there.
Officials also said any change in the use of a house to a holiday home or second home would have to have planning permission.
