Deck Replacement in Star, ID

Which Star decks are due for replacement?

Three groups make up most of the calls. The biggest is the builder deck on a home from Star's first modern subdivisions. By local history as Build Idaho and Wikipedia tell it, Star lost its city charter in 1929 and incorporated again in December 1997, and the subdivisions that followed are now old enough that their original pressure-treated decks are wearing out: soft joist tops under the boards, guard posts lagged to a rim that has loosened, and stairs landing on bare dirt.

The second group is around the original townsite along State Street and on older farm parcels, where decks were added in stages over decades, often off a porch or a back door that was never meant to carry one. The third is the tall view deck on foothill acreage north of town, where height, wind and long posts make a tired deck a safety question rather than a cosmetic one.

Does a deck replacement need a permit in Star?

Yes, if the new deck is 30 or more inches above grade, which is Star's published line. A deck torn down to the footings and rebuilt is new construction under the 2018 IRC, regardless of whether the old one had a permit. A low deck under 30 inches can usually be replaced without one, but setbacks and HOA approval still apply, and changing the footprint is where setback trouble starts.

Star also has a specific owner-builder rule. A homeowner can pull a permit for a primary or secondary residence, but the owner who pulls it has to do all the work on it and must plan to live in the home within 12 months of completion. If a contractor is doing the work, the contractor pulls the permit, and Star's FAQ says contractors need a current, valid license through the State of Idaho to apply. A split job, where the owner tears off the old deck and hires out the rebuild, should be sorted out before the application goes in. The Star deck permit guide covers the submittal itself.

Is your deck in Star, Ada County or Canyon County?

Check before the drawings, because a Star mailing address does not settle it. Star's building FAQ notes that ZIP codes do not follow city limits and points owners to the Certificate of Occupancy and county parcel records; the Ada County Assessor's property lookup is the quick check. The city itself sits mostly in Ada County with a portion in Canyon County, and acreage parcels near the edges are often unincorporated. Each office publishes its own numbers, and they are not identical:

For an open deck, the snow figure matters less than it does for a roof, but a replacement that adds a cover is drawn to whichever numbers the permitting office uses. The Ada County and Canyon County overviews list the county offices if the lookup shows the parcel is outside Star.

What can be reused from an old Star deck?

Usually less than the owner hopes, and we decide member by member:

• Footings: kept only if they reach 24 inches, are sized for the new layout and bear on undisturbed soil. Builder-era decks sometimes sit on precast blocks or shallow piers in backfill.
• Posts and beams: rarely kept. Post bottoms in irrigation spray decay first, and beams sized for a wood-board deck may not suit a new composite layout.
• Joists: possible on a resurface, unusual on a full replacement, because composite needs tighter spacing than many old wood decks were framed at.
• Ledger: always opened up. We pull the boards along the house, check the rim, and rebuild with bolts and flashing or switch to a freestanding beam.
• Guards and stairs: rebuilt to current dimensions, 36-inch guards that stop a 4-inch sphere and stairs with consistent risers.

If the frame turns out to be sound and only the surface is tired, the project is a repair or resurface instead; see deck repair in Star and the repair-or-replace guide.

Replacing a tall view deck on foothill acreage

North of town toward the foothills, the larger-lot communities put decks on the main floor of homes facing long views, often over ground that drops away. A deck 10 feet in the air on a slope, in Exposure C wind, is a different job from a low deck in a subdivision. Tall posts need lateral bracing or engineered bases, guard posts need hold-down connections like the 1,800-pound details in the American Wood Council's DCA 6 guide, and the beam layout often changes so posts land on firmer ground.

Acreage also gives room to take the deck off the house. When the old ledger is suspect, a freestanding deck on its own beam line a few inches from the wall avoids loading a tired rim and keeps water away from the house. These lots are also the ones most likely to be outside city limits, so confirm the jurisdiction first.

River lots: flood zones and damp footings

Along the Boise River on the south edge of town, a replacement may need a planning step before the building permit. Star's planning FAQ says development in certain flood zones requires a Flood Plain Development Permit and asks owners to book an appointment with planning to have the property evaluated. Star's design criteria note that the 2003 flood insurance rate maps are in effect. A same-size rebuild on the same footings is the least likely to draw extra review; a bigger footprint, fill or new footings in the mapped zone is where to ask early.

River soil also stays damp. Cottonwood shade keeps old frames wet, and footing holes can hit groundwater or soft soil in a way that open-field lots do not. We dig a test hole at the site visit on river lots before pricing the footings.

How long does a Star deck replacement take to permit?

Plan for the calendar, not just the build. Star's FAQ puts typical review at two to four weeks for small residential projects and four to six weeks for larger ones, adds three to four weeks for each revision or correction, and says the city does not expedite plans for a fee. All permitting is online, inspections are requested through the portal rather than by phone or email, and a rough and a final inspection are not scheduled for the same day. Concrete still needs unfrozen ground, and NOAA's normals for the Boise airport put the median last spring freeze on April 24.

Working back from a late-spring deck, that usually means HOA approval in winter and a permit submitted by early spring. Published ranges for tear-off and rebuild are in the deck replacement cost guide. For the same work under Eagle's rules next door, see deck replacement in Eagle.
