Tom,

Actually, the perc test (for percolation) is to determine how fast the ground will absorb water and how quickly it disperses it. This is vital to finding out if a septic system will work on the lot for the purpose of building your home. If the test results show the soil is ok to allow a septic system and therefore a home, based on the results, it will determine how many bedrooms the home can have, not the number of bathrooms. If, for example, it "percs" for a 3 bedroom home, it doesn't matter if you have 2 bathrooms or 5, it only says the maximum number of bedrooms in the home can be 3.

If the lot is a lakefront lot, there are some other factors to consider, however I don't know if you're talking about a lakefront lot or not.

Hope this helps. If I can be of any further assistance, please contact me anytime. Thank you.
