Mount Pleasant's crackdown on new multifamily projects has created a snag for a senior living development that's looking to expand.

Liberty Senior Living wants to add 109 residential units to its 279-unit continuing care operation at its South Bay community between Hungryneck Boulevard and Rifle Range Road.

The town had previously approved up to 398 continuing care units on part of what's called the Central Mount Pleasant tract.

Liberty now needs another approval because of the local moratorium on new apartment and condominium developments that took effect in early 2017. The development hiatus remains in effect until at least March 2024, barring a reversal.

The town also has a building permit allocation system that allowed 500 multifamily units between 2019 and 2024, and all of them have been allocated to date, according to a planning official.

The Planning Commission will consider the South Bay request Aug. 23.
