How much deposit can a basement finishing contractor ask for in Idaho?

Idaho has no statutory cap on contractor deposits. No specific statutory cap on residential renovation deposits. For basement finishing, industry standard is 10% — meaning on a $39,494 project, expect $3,949 max. Any request above $5,924 is a red flag.

Industry standard for basement finishing: 10%. Long job (8–16 weeks). Industry standard: 10% deposit + progress draws — basement projects are the most common venue for contractor abandonment. Most legitimate Idaho contractors will follow this norm regardless of whether the state has a statutory cap.

Idaho doesn't have a statutory cap, but industry-standard deposits sit between 10–25% for most basement finishing projects. A request above 15% is a strong signal of cash-flow problems (the contractor is funding earlier jobs with your money) or outright fraud risk. Get 2 more written quotes before signing anything.

Best practice in Idaho: 10% deposit at contract signing → milestone-based progress payments tied to inspectable phases (rough-in, mid-build, substantial completion) → 5–10% retention held until punchlist + final inspection sign-off. Never pay materials in full upfront; if your contractor goes under, the materials supplier owns those goods, not you. Pay via check or credit card — never wire transfer to a personal account.
