Upon the recommendation of the agency, a redevelopment plan may be modified at any time by the legislative body or by the legislative body at its own discretion. The legislative body may, at its discretion, hold a public hearing on the proposed modification provided, that, if the plan is modified after lease or sale by the agency of real property in the project area, the modification shall be subject to rights at law and in equity as the lessee or purchaser, or his or her successor or successors or assigns in interest, may be entitled to assert.
