Glenn County, CA Zoning Overlays & Bonuses: Density Bonus Law (2026)

020, adopted to implement California Government Code Section 65915, requires the Board of Supervisors to grant either a density bonus with an additional concession or incentive, or an incentive of equal financial value, once a housing project qualifies. The density increase must be at least twenty-five percent over the maximum density authorized by the County General Plan. 5, at least 10 percent for very low-income households under Health and Safety Code Section 50105, or at least 50 percent for senior citizens. A developer must sign a binding agreement with the county spelling out compliance standards and the county's remedies if the developer fails to keep units available to the intended households.

040 lists the kinds of concessions the county can grant beyond the density increase itself, including modified standards for building height, open space, lot size, street access, off-street parking, landscaping, fencing, or off-site improvements, and even mixed-use zoning within the project where the General Plan allows it. 050 sets the affordability term at thirty years if the project takes an additional incentive, or ten years without one, and requires the developer to file a yearly accounting with the planning authority reporting occupied units, vacant units, and any shortfall against the required set-aside.
