Carson FAQ
Is there a public Carson STR registry?
No. The only registration is the TOT certificate issued under CMC §6400, which is held by the operator and posted at the property — not a public list.
Do I need both a TOT certificate and a business license?
Yes. The TOT certificate authorizes you to collect the city's 9% transient occupancy tax. A separate City of Carson business license is also required under the city's general business-license provisions.
Are there annual safety inspections?
No. Carson does not require STR-specific annual safety inspections because no dedicated STR ordinance has been adopted; only general building, fire (LACoFD), and code-enforcement standards apply.
Downey FAQ
Do I need a permit to run an Airbnb in Downey?
Downey does not currently require a specific STR permit, but you must obtain a general business license and collect the Transient Occupancy Tax. Check zoning requirements with the Planning Department.
Will Downey regulate short-term rentals in the future?
The city may eventually adopt specific STR ordinances. Contact the Planning Department at (562) 904-7154 for the latest requirements.
