You need 4+ free equipment slots (<= limit - 4) for drops/construction/development/remodeling, so you can have more than limit - 4 without going over limit on those actions (and also on ranking rewards, if you don't have enough slots you can receive them in parts, every time you free enough slots).

For events it's just 20+ free equipment slots (<= limit - 20).
