Principal-structure setbacks in unincorporated Collier County depend on your zoning district. In the common RSF-3 district the front yard is 30 feet, side yards 7.5 feet (10 feet waterfront), and rear yard 25 feet. Estates lots require far larger 75-foot front and rear setbacks.
Collier County LDC 4.02.01, Table 2.1

In unincorporated Collier County, single-family homes in the RSF districts may be up to 35 feet tall. Estates (E) lots are limited to 30 feet, and Rural Agricultural (A) allows 35 feet. Spires, chimneys, flagpoles, and antennas are exempt from the height cap.
Collier County LDC 4.02.01, Table 2
Table 2. Building Dimension Standards for Principal Uses in Base Zoning Districts. Maximum Building Height (feet): A: 35. E: 30. RSF-1: 35. RSF-2 through RSF-6: 35.

Most residential base districts in Collier County set no maximum building-coverage percentage for the principal home, relying on setbacks instead. Accessory buildings, however, may not cover more than 5 percent of total lot area in any residential district.
Collier County LDC 4.02.03 B
Accessory buildings shall not occupy an area greater than five (5) percent of the total lot area in all residential zoning districts, or occupy an area greater than forty (40) percent of any building envelope (i.e., area of lot remaining for building purposes after accounting for required setbacks), whichever is the lesser.
