Decks and outdoor living in 4S Ranch

What is different about 4S Ranch

• 4S Ranch is unincorporated, so building permits come from the County of San Diego Planning & Development Services, not the City of San Diego.Source: County of San Diego Planning & Development Services (PDS)
• The County's residential deck handout says decks not more than 30 inches above grade and not over any basement or story below do not require a building permit.Source: County of San Diego Planning & Development Services, handout PDS 044 (residential decks)

4S Ranch is one of the newest communities on our list, with only about a quarter of its homes built before 1990, so decks here are seldom rotted. Requests tend to be about function: a larger entertaining area, shade for a west-facing yard, or a cover that works with the existing roofline. Because the community is unincorporated, the County reviews the plans, and its deck handout draws the permit line at 30 inches above grade for decks with nothing below them. Backyards here are often terraced, and one corner can cross that line.

Composite decking is common on newer homes because it holds its color and needs less upkeep than wood, and we price it by the board layout, the substructure and the railing you choose. If your neighborhood has homeowners association review, approval can come before the County filing. Ask your association for its guidelines and any approved material list, and send them to us before the visit. We bring the County handout along, confirm the measuring points, and write the permit steps into the quote.
