In unincorporated Nevada County, Sec. 12.04.105 governs building setbacks. Side and rear setbacks are commonly 30 feet, but parcels under 3 acres served by community/public water may reduce them (to 5 ft side / 20 ft rear in R1-R3, or 10 ft side / 20 ft rear in RA, AG, AE, FR) if fire-protection measures are met.
Maximum structure height in unincorporated Nevada County is set by base zoning district in Article 2 of the County Code, so the exact limit depends on your district. The Building Setbacks section (Sec. 12.04.105) does, however, allow architectural features like eaves, chimneys, and bay windows to project up to 5 feet into front and rear setbacks.
Maximum lot coverage in unincorporated Nevada County is established by base zoning district in Article 2 of the County Code, so the allowed coverage depends on your district rather than a single countywide figure.
