The Dunedin City Council has sent about 6000 letters to people across the city whose homes fall within areas identified in the city's draft spatial plan, or growth strategy, released last month.
The spatial plan could bring about major changes to the face of the city, as planners look at ways to deal with an expected extra 7600 residential units needed by 2031.
The plan has identified possible changes to neighbourhoods, including areas where an increased density of housing could be planned for, inner city living encouraged, or special character areas, which restricts the work that can be done on a building without consent from the council, extended.
Depending on decisions made, it could mean changes are included in the city's next district plan review.
The letters tell householders their property falls within one of the areas identified for potential change, and invites them to attend information sessions. One example was in the City Rise area, where it is proposed special character areas be expanded.
Council heritage policy planner Glen Hazelton said more than 30 people had contacted the council for information so far.
The spatial plan signalled the direction of ideas that would feed into the district plan which would begin next year, he said.
