Layton, UT Zoning Overlays & Bonuses: Density Bonus Law (2026)

090 governs how a Planned Residential Unit Development (PRUD) overlay applies to its underlying zoning district, and subsections 15 through 17 set the density bonus mechanics. 7 units per acre. If a PRUD spans more than one residential zoning district, the total allowed units are calculated by adding up each district's allowance, including its applicable bonus, though the actual dwelling units can be placed without regard to the internal district boundaries. The Land Use Authority grants the bonus, capped at 40% total, only in exchange for specific design options: up to 15% for exceeding the minimum base open space requirement, up to 10% for recreation and site amenities such as pools or tennis courts, up to 10% for enclosed two-car garages on all units, up to 10% for raising exterior masonry coverage on street-facing walls from 20% up to 75%, up to 5% for upgraded fencing materials such as brick, stone-columned vinyl, or wrought iron, and up to 10% for streetscape enhancements like supplemental lighting and expanded landscaping along a street frontage.

Base open space requirements themselves range from 12% of gross site area in the R-S, R-1-10, and R-1-6 districts up to 60% in the A district, with an added 8% in Neighborhood Ag Heritage Overlay areas unless waived through a transfer of development rights.
