from exterior sources of ignition, openings into direct-vent (sealed combustion system) appliances or mechanical ventilation air intakes.

I am asking about the distance the generator needs to be from the house.
 
generally manufacture's installation and/or guides in this case...... suggestion, ensure it is at least five feet away and have the exhaust pointing away from your house and the neighbor's house. The five feet will ensure adequate access to service the generator and allow a push mower to cut behind it......

What county are you needing to reference? Zoning, plumbing, and electrical permits are required.

Zoning and the manufactures instruction based on NFPA 37 Stationary combustion Engines and Gas Turbines and NFPA 110 Emergency and Standby Power Codes.
