Summary
In the unincorporated H Overlay District, Orange County lets developers who consolidate small parcels into a site of one acre or more raise base density from 70 to 84 units per acre: a 20% jump, stacked with the state density bonus up to a 45% cap.
A graduated density incentive shall be granted when parcels smaller than one-half (0.5) acre are consolidated as part of a project. The increased density shall be in addition to any other density bonus available under this Zoning Code, to a maximum of forty-five percent (45%) total, and shall be calculated as follows: Less than 0.50 acre – 70 units/acre; 0.50 to 0.99 acre – 77 units/acre (10% increase); 1.00 acre or more – 84 units/acre (20% increase).

Full Breakdown
Orange County's H "Housing Opportunities" Overlay District, applied to 100% affordable rental and owner-occupied projects in unincorporated commercial, industrial, and multifamily zones, sets a base density of 70 dwelling units per acre. Section 7-9-44.7(c) adds a graduated incentive for lot consolidation: parcels combined into a site of 0.5 to 0.99 acre reach 77 units/acre (a 10% bump), and 1.0 acre or larger reaches 84 units/acre (20%). That increase stacks on top of any density bonus the project separately earns under Section 7-9-87 and State Density Bonus Law, capped at a 45% total increase above the base. The bonus applies only where an affordable Site Development Permit is approved.
Violations & Fines
Density above the table requires an approved Site Development Permit and a recorded compliance restriction; building beyond it without that permit is a zoning violation subject to County code enforcement.
