what is the exact requirement for deck railings to pass FHA appraisal?

Not sure what part you are asking about. But their are railing requirements if the deck is more than 30 inches off the ground, and the railings must be in good condition. If it is missing items, and looks like it may fall down, they will require it be repaired. For FHA loans in WI, MN, and SD, visit me at www.WI-MortgageBroker.com
