How far do I put the septic tank from my house? Generally speaking, septic tanks are usually 10 feet to 50 feet from the foundation of the home. This is a question that is usually decided by the engineer and the septic inspector after the perk test has been completed. A septic perk test should always be performed before you purchase the property.
A perk test approval contingency clause should be made part of the purchase agreement to ensure a return of you down payment money in the event the soil dose not perk. In most cases, if the soil does not perk, it will be difficult to obtain a building approval and the necessary permits required before construction can be started.
