Lincoln, CA
Placer County
Lincoln has not adopted a primary-residence requirement for short-term rentals because it has no STR ordinance at all. Instead, the Zoning Code's residential districts contemplate permanent occupancy: §18.16.200(1)(b) for SRO units expressly bars transient occupancy, and home occupations under Ch. 18.62 must be 'incidental and secondary' to residential use of the dwelling.

Rocklin's adopted RMC Chapter 5.22 does NOT require the operator to live in the home as a primary residence. The Planning Commission's draft included a primary-residence condition, but that requirement was struck before Council adoption. Investor-owned and non-owner-occupied whole-home STRs are legal in Rocklin so long as the 90-day annual cap, 6-person occupancy limit, and 30-minute response rules are satisfied.

Lincoln FAQ
Does Lincoln require STR hosts to live on-site?
Lincoln has not adopted any STR ordinance, so there is no specific primary-residence rule for STRs.
Are there day-count limits on hosted stays?
No. Lincoln has not adopted hosted-only or day-cap limits like other California cities.
Could that change?
Yes - Lincoln's City Council has authority to amend Title 5 and Title 18 to regulate STRs at any time.
Rocklin FAQ
Can I buy a Rocklin home solely to run it as an Airbnb?
Yes. RMC 5.22 does not require the operator to occupy the property as a primary residence. You will still need a Rocklin Business License, an STR Permit, and you remain capped at 90 rental-days per year.
Why does the application ask about primary residence?
The form collects that information for administrative purposes (e.g., HOA documentation, contact verification) but does not deny permits based on the answer. Reporting on adoption confirms the primary-residence requirement was removed.
Can my HOA stop me even if Rocklin allows it?
Yes. HOA CC&Rs that prohibit rentals of less than 30 consecutive days are privately enforceable; the STR application specifically asks operators to disclose any HOA restrictions.
