Summary

Redding bans short-term rentals of accessory dwelling units outright. Municipal Code Section 18.43.140(I)(1) sets a thirty-day minimum lease for any unit on a property developed with an ADU or junior ADU and separately prohibits using either unit as a short-term rental as defined in the city's Section 18.43.180.

Rental Limitations. No unit on properties developed with accessory dwelling units and/or junior accessory dwelling units may be leased/rented for periods of less than thirty days, and no such unit shall be used as a Short-Term Rental as defined by Section 18.43.180.

Full Breakdown

180. That cross-reference matters because Redding's short-term rental chapter separately regulates transient stays citywide; by writing its own thirty-day floor and STR ban directly into the ADU standards, the city forecloses the argument that an accessory unit could qualify for STR treatment under a different provision. The rental floor sits alongside the separate-sale limitation in subsection (I)(2), which bars selling a unit apart from the primary parcel except as the Government Code allows, the owner-occupancy rule in subsection (I)(3), and the certificate-of-occupancy limitation in subsection (I)(4), which ties an ADU's occupancy sign-off to the main dwelling already holding one.

Because ADUs are approved administratively under subsection (B) without a discretionary permit or hearing, the thirty-day rental floor functions as the primary ongoing check on converting new accessory housing stock into nightly or weekly vacation rentals rather than long-term housing, and it applies from the moment the accessory unit is built regardless of whether the owner lives on-site.

Violations & Fines

Renting an ADU or JADU for less than thirty days or operating it as a short-term rental violates Section 18.43.140(I)(1) and is enforceable as a code violation under Title 1. Section 1.12.020 makes an uncorrected violation a misdemeanor punishable by up to a $1,000 fine, six months in county jail, or both, with each rental day counted as a separate offense.

Frequently Asked Questions

Can I rent my Redding ADU on Airbnb?
No. Section 18.43.140(I)(1) bans using an accessory dwelling unit or junior ADU as a short-term rental and requires a minimum thirty-day lease term for any unit on the property.
What is the shortest lease term allowed for an ADU in Redding?
Thirty days. Section 18.43.140(I)(1) prohibits leasing or renting a unit on a property with an ADU or JADU for any period shorter than thirty days.
Does the short-term rental ban apply if I live on the property?
Yes. The thirty-day floor and STR ban in Section 18.43.140(I)(1) apply regardless of whether the owner occupies the primary residence, since owner occupancy is a separate requirement under subsection (I)(3).
