Interior (Enclosed) Additions: An enclosed porch is classified an interior addition (such as sunrooms, 3-season room, cold porch etc.) and requires a footing/foundation to be continuous for perimeter walls. Smaller single story additions allow the use of a trenched or formed foundation when additions are considered an enclosed structure (see Trench Foundation below). Note: glass installation is governed as part of exterior walls.
Open decks: are level floor surface structures built-up above the ground levels having no roof or walls for enclosures. Decks typically include guardrails around open perimeter of the deck surface and steps leading to grade. Decks with more than 30 inches in height above grade require guardrails, which shall be at least 36 inches in height measured vertically above the walking surface. Guardrail opening must have spacing such that a 4 inch sphere cannot pass (B 1021.2 & 1021.3). Open porch/decks are an exterior structure allowing the use of concrete piers and posts sized to support deck, roof loads and uplift only.
Patios: are classified as exterior finished ground walking surfaces without walls or a roofed over structure and do not require foundation walls. Patios typically are paved with brick, tiles or even stone and open to the sky. Patios are ground coverings for the purposes of lot coverage. A roof covered patio would be classified as a Porch when attached to a residence or Gazebo when detached. Gazebos are limited to 200 square feet.
