Allows developers to build in specified areas densities that are higher than normally allowed.

An increase in the density otherwise allowed in a given zoning district which may be granted under specific provisions of the Zoning Ordinance when a developer provides excess open space, recreation facilities, or affordable dwelling units (ADUs), etc.

In 2001, the County added a 25% density bonus provision to its Zoning Ordinance. The bonus permits both market-rate and affordable units, with the income from the market-rate units designed to offset the cost of the subsidized units.

Density bonuses are increases in commercial floor to area ratio (FAR), typically provided to developers as a reward or incentive when they provide a public amenity including parks, plazas, and affordable housing. .A density bonus allows a developer to construct a building beyond the intensity allowed by zoning.

An increase in the allowable number of residences granted by the city or county in return for the project's providing low- or moderate-income housing (see Government Code Section 65915).
