Density bonus
A density bonus lets a developer build more than zoning allows, in exchange for a public benefit like affordable housing.
Also called bonus density or incentive zoning.
What it tells you
A density bonus request means a project is pushing for more homes than the zoning allows, often with an affordable share. It points to multifamily or mixed-use building on that site.
How it moves through a city or county
- The developer requests the bonus with a rezoning, site plan, or building application.
- Staff check that the benefit qualifies, such as the share of affordable units.
- The benefit is secured by an agreement or a recorded restriction.
- Staff, the planning commission, or the council approves it, depending on the program.
Some bonuses are granted by right once the benefit is offered; others are negotiated. The affordable share and the size of the bonus differ by program.
Common questions
- Do density bonuses only apply to affordable housing?
- No, many density bonus programs reward other benefits too, like open space or green building. Affordable housing is the most common, and in California it is set by state law.
- Does a density bonus need a public hearing?
- Whether a density bonus needs a public hearing depends on the program. Some are granted by staff once a project meets the rules; others ride on a rezoning or planned unit development that goes to hearings.
Rules vary by state, county, and city. These pages describe common practice, not legal advice.
