Build Idaho's 2026 guide placed the 2025 new-home median near $574,000.
What's different about decks in Star?
- Star sets its deck threshold at 30 inches above grade, and its building FAQ lists patio covers, pergolas and awnings as permit work when attached at any size or detached and larger than 200 square feet. A ground-level deck can therefore be exempt in Star while the pergola on it is not.
- Wind is designed for, not assumed. Star's adopted design criteria list a 115 mph design wind (risk category II), so covers, pergolas and privacy walls need uplift-rated post bases and roof ties. Open lots with no mature trees put that wind straight onto the structure.
- Most Star decks go onto new-construction lots, where the soil beside the foundation is loose backfill and the pressurized irrigation was installed weeks earlier. Footings need to reach undisturbed soil at the 24-inch frost depth, and sprinkler lines get traced before digging.
- Bare yards make the deck the first shade on the property. A cover or pergola on the west side and lighter capped composite keep a new Star deck usable through July and August until trees fill in.
Star's own criteria repeat the valley's 20 psf ground snow load and 24-inch frost depth. The nearest long climate record is the Boise Air Terminal, which logs 108 freezing nights and 17.6 inches of snow a year; Star's open farm-ground setting adds more wind exposure than most Boise neighborhoods see.
Does a deck in Star need a permit?
Deck permits in Star go through City of Star Building Department. Rules differ by jurisdiction — we confirm the threshold and submittal list for your lot during the estimate.
Most newer Star subdivisions have CC&Rs with architectural review covering deck size, color and covers. Submit the HOA packet with the same drawings used for the city permit.

Star deck questions
- Do you build decks in Star?
- Yes. Most of our Star work is on newer homes along the Highway 44 corridor and in the subdivisions north and south of downtown, typically composite decks with a pergola or cover to shade an open yard. Each estimate checks Star's 30-inch permit line, the pergola permit rules and the HOA's architectural guidelines.
- When does a deck need a permit in Star?
- When it is 30 or more inches above grade. Star's building FAQ also requires permits for patio covers, pergolas and awnings that are attached to the house at any size or detached and over 200 square feet. A concrete slab of any size needs no building permit. Setbacks and HOA approval still apply to exempt work.
- Why does wind matter for a covered deck in Star?
- Star's design criteria specify a 115 mph design wind, and most Star lots are open former farm ground with little to break it. A roof or pergola acts like a sail, so posts need uplift-rated bases, beams need positive ties and the house connection must be flashed and fastened for those loads.
