Plumbing rough-in for a bathroom or utility sink, floor drains, thickened slab sections for a vehicle lift, and conduit runs for future power. Every one of these costs a fraction during construction and requires cutting concrete afterward. If there is a ten percent chance you will want it someday, rough it in.

You can sometimes extend a building's footprint later. You essentially cannot raise its walls. If a boat, an RV, a lift, or overhead storage is anywhere in your future, buy the height now. Twelve feet of clear height is the minimum for a two-post lift and fourteen is better.

Setbacks, lot coverage, impervious surface limits, accessory structure height caps, and septic capacity. Most stalled outbuilding projects in this region die at one of those, not at price. Check them before you pay anyone to draw anything.

If you are on septic, adding bedrooms requires system capacity. An expansion needs a soil evaluation and county environmental health approval, and on some soils it simply is not possible. This is the first thing to check on any ADU outside a sewered area — it can end a project before design starts.

Metal buildings sweat. Uninsulated slabs sweat. Small tightly-closed rental units grow mold if the bathroom fan vents into the attic instead of outside. Moisture management in southeastern NC is a specification issue you address during design, not something you fix with a dehumidifier afterward.

An unpermitted living space does not count toward appraised square footage, can derail a sale during due diligence, and can create insurance problems after a claim. Whatever you saved on permitting comes back with interest. Build it through the permit office.

If you are comparing three contractors and two gave you a number over the phone, you have one estimate and two guesses. Insist on an itemized written scope with explicit allowances for finishes, so you know exactly what triggers an overage before anyone starts.

The home office becomes a guest suite, becomes a rental, becomes your mother's apartment. A step-free entry, a 36-inch bathroom door, and blocking for grab bars cost almost nothing at framing. Buildings that hold value are the ones that can serve three purposes over twenty years.
