Generally, a patio is more accessible than a standard deck because patios are constructed at ground level. However, decks can be made accessible by adding a wheelchair-accessible ramp, a vertical lift, or a stair lift along the entry. An ADA-compliant deck ramp costs about $3,000 on average. The additional investment will provide a much friendlier experience for your guests with movement impairments.

Yes, you can attach a deck to a mobile home, but it’s important that the work be done correctly to avoid the potential for major damage to your home. Many building codes require that any additions to mobile homes—including decks—be either freestanding or have their own support structures. Getting permits may require submitting the home's original floor plan, the proposed floor plan, framing details, and more. 

The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.
