Frisco FAQ
Does Frisco have a hard floor-area-ratio cap on new homes?
Most legacy zoning districts use lot coverage and setbacks rather than floor-area-ratio. Some planned developments add explicit floor-area-ratio caps, so check the underlying zoning district carefully.
Can my HOA block a tall replacement house even if zoning allows it?
Yes. HOA architectural-review rules and deed restrictions can be more restrictive than Frisco zoning, blocking massing or styles even when the city would otherwise approve the design.
