Summary
Seminole County's Dimensional Standards Table (Sec. 30.7.3) controls building bulk through minimum lot area, yards, and an open-space requirement rather than a fixed maximum lot-coverage percent. Multiple-family and mobile-home districts must keep 25% (R-4: 35%) of parcel area as open space; single-family R-1 districts rely on setbacks and living-area minimums.
Open Space (11, 12): R-3 25%; R-3A 25%; R-4 35%; RM-1 25%; RM-2 25%; RM-3 25%; RP 25% (% of Parcel Area). (11) Natural lakes and/or conservation areas within a development site shall not be credited to a combined maximum of more than fifty (50) percent of the required open space.

Full Breakdown
Unlike many Florida counties, Seminole County's LDC Table 30.7.3 does not set a single 'maximum lot coverage' percentage for the single-family R-1 districts (the open-space column shows '-'). Instead, building bulk is controlled by minimum lot area (e.g., R-1 requires 8,400 sq ft; R-1AAAA 21,780; RC-1 43,560), minimum lot width, the front/side/rear setbacks, the 35-foot height cap, and minimum living area per unit. An Open Space requirement of 25 percent of parcel area applies to the R-3, R-3A, RM-1, RM-2, RM-3, and RP districts (35 percent in R-4) and to commercial and industrial districts. Natural lakes and conservation areas count toward no more than 50 percent of required open space (footnote 11).
Violations & Fines
Development that fails to provide required open space or violates the dimensional standards is caught at site-plan/plan review and requires a variance from the Board of Adjustment.
