Full Breakdown
Implementing Government Code §§ 65915-65918, Manteca grants a density bonus, plus incentives or concessions, to housing developments meeting affordability thresholds. A project with 10% lower-income units gets a 20% density increase, rising 1.5% for each added percentage point of low-income units, up to a 35% maximum bonus; very low-income and senior/moderate-income projects follow parallel formulas. Granting the bonus does not itself require a General Plan amendment or rezoning.
Violations & Fines
Density bonus units carry recorded affordability/deed restrictions; converting or failing to maintain them as affordable violates the approval conditions and can trigger enforcement or loss of continued eligibility for the bonus.
