Summary

Ada County cannot require short-term-rental operators to carry additional insurance. Idaho Code 67-6539 bars STR-specific insurance mandates, though hosts should still carry adequate coverage voluntarily.

These county ordinances apply to unincorporated areas of Ada County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Requiring additional insurance.

Full Breakdown

Idaho Code 67-6539(2)(a)(iii) prohibits 'requiring additional insurance' as an STR-specific obligation. Neither Ada County nor any Idaho city may condition short-term rental on a minimum liability policy or STR endorsement beyond what applies to any homeowner. That said, standard homeowner's policies often exclude commercial short-term rental activity, so operators are strongly advised to obtain STR or landlord coverage or rely on platform host-protection programs for their own protection, not because an ordinance requires it. Generally applicable safety and tax rules still apply.

Violations & Fines

No insurance requirement may be enforced by the county; a lack of coverage is a private financial risk to the host, not a code violation.

Frequently Asked Questions

Must I buy special STR insurance in Ada County?
No. Idaho Code 67-6539 bars requiring additional insurance. Coverage is still strongly recommended because standard homeowner policies often exclude short-term rental activity.
Does Airbnb's coverage replace my own policy?
Platform host-protection programs help but have limits and exclusions; most experts advise a dedicated short-term-rental or landlord policy for full protection.
