Government Code, § 65589.5, subdivisions. (d), (h)(7), and (i)
Like the ability to deny a project, the HAA does not prohibit a local government from exercising its authority to condition the approval of a project, but rather provides limitations and conditions for the application of certain conditions. Specifically, the HAA limits the application of conditions that lower the residential density of the project, and, for housing affordable to lower- and moderate-income households and emergency shelters, conditions that would have a substantial adverse impact on the viability or affordability of providing those units unless specific findings are made and supported by a preponderance of the evidence in the record[6] .
For purposes of the HAA, “lower density” includes any conditions that have the same effect or impact on the ability of the project to provide housing. This could include a condition that directly lowers the overall number of units proposed (e.g., the development proposes 50 units, but the local government approves only 45 units). It could also include indirect conditions that result in a lower density (e.g., a development proposes 50 units at 800 square feet per unit but the local government conditions the approval on the provision of 850 square feet per unit, resulting in the project having to provide fewer units to accommodate the increase in square footage). Another example would be a reduction in building height that would result in the project being able to provide fewer units than originally proposed.
Local governments must also consider if imposed conditions of approval would have an adverse effect on a project’s ability to provide housing for very low-, low-, or moderate-Income households at the affordability levels proposed in the housing development project. This includes provisions that would render the project for very low-, low-, or moderate-income households infeasible or would have a substantial adverse effect on the viability or affordability of the proposed housing. For example, project approval for an affordable housing development might be conditioned on the need to use specific materials that significantly increase the cost of the project. This additional cost could either render the project financially infeasible altogether or require substantial changes to the affordability mix of the units where fewer very low-income units could be provided. In these cases, it is possible that the conditions would violate the HAA.
Conditions that should be analyzed for their effect on density and project feasibility (for affordable projects) include, but are not limited to, the following:
Design changes
Conditions that directly or indirectly lower density
Reduction of the percentage of a lot that may be occupied by a building or structure under the applicable planning and zoning.
