Whether a primary entrance or back patio, well designed steps built to code should be an integral part of the design rather than an after thought. Providing safe, convenient transitions for daily use is priority as well as just making life less stressful when carrying a stack of burgers in from the grill. Even when not required by building codes, a sturdy handrail is always a good investment. Local rules vary but typical requirements are a three foot deep top landing and a handrail when there are three or more successive risers.
