Kirkland Deck Builder | Deck Safety Continued Knowing your deck's weight capacity is critical for safety, particularly if you intend to add furniture, hot tubs, or large gatherings. Most residential decks are designed to support 50 pounds per square foot, but framing materials and joist spacing affect this figure. Reinforcing the frame with additional support beams or steel brackets can help to increase its load capacity. If you intend to install a hot tub, proper weight distribution is critical to avoiding structural damage. Regular inspections for sagging, cracks, and weak connections can help prevent accidents. Hiring a professional to assess the strength of your deck before adding heavy items is always a good idea. For more info visit: https://intercrusservice.com/kirkland
