The project I am working on is over the light allowance, but does not have any money in the budget to add mechanical glare control devices. Is there an alternative compliance path... something cheaper? Would non-mechanical shading devices suffice?

Have you accurately modeled the terrain and surrounding buildings? This will sometimes help. Models in flat planes are not true representations of the majority of all buildings. Plantings, such as coniferous trees can be used to reduce the direct solar aspect.
What you mean by mechanical is automatic?
