Secondly, the bill enables more medium-density housing across our main city. Tier 1 councils will need to change their planning rules so most of their current and future residential areas are zoned for medium-density housing. This allows more town houses and units to be built, but, importantly, it does not require it. This is enabling legislation that will give people in our cities more choice. The bill does this by introducing medium-density residential standards that provide a minimum level of development in these areas. What this means is people can, as of right, build up to three homes of up to three stories on up to 50 percent of most sites, without the need for a resource consent. Currently, most council planning rules may only allow for one home of up to two stories.
