Landlord-Tenant Rights and Responsibilities (Rio del Mar, Unincorporated Aptos)

Rights and responsibilities for renting a single-family home to Jai’s 4-person cohort at 613, Rio del Mar (unincorporated Aptos, Santa Cruz County). Three layers: California statewide law (the floor), the unincorporated-county local rules, and the lease mechanics (disclosures, co-tenancy, insurance). Not legal advice — have a California landlord-tenant attorney review the final lease packet.

Bottom line for the cohort

Local rules — unincorporated Santa Cruz County / Rio del Mar

QuestionAnswer
County rent control / stabilization?No
County just-cause beyond state law?No (state AB 1482 only)
County rental inspection / registration / license (long-term)?No (STRs excepted; the Ch. 21.06 inspection program is the City, not the county)
County anti-retaliation / anti-harassment?Yes — County Code Ch. 8.43 (Ord. 5410, 2022)
STR-conversion tenant safeguard?Yes — displacing a long-term tenant to create a short-term rental requires paying the tenant 6 months’ rent (2025)
Free dispute mediation?Yes — Conflict Resolution Center, Housing Mediation (voluntary)

A long-term cohort tenancy is categorically outside the county’s vacation-rental (STR) regime (County Code §13.10.694) — ongoing tenancy to the same renter is explicitly not a “vacation rental.” AB 1482 cap % for Santa Cruz County (grounded): Santa Cruz is not a separately-published BLS metro, so it uses the California statewide (“all other areas”) CPI (calculated by the CA Dept of Industrial Relations) — not the SF-metro 6.3%. For Aug 2025–Jul 2026 that statewide cap is 7.7% (5% + 2.7% CPI), corroborated by the neighboring statewide-CPI counties (Monterey, Santa Clara, Sonoma, Napa, Solano all 7.7%). The Aug 2026–Jul 2027 figure tracks the April 2026 CPI (published mid/late June 2026); confirm the live number via CAA’s “Find Your CPI” tool (caanet.org/ab1482) at lease signing.

AB 1482 single-family exemption — the key operational item

A single-family home escapes the rent cap and just-cause only if both: (1) the owner is not a REIT, corporation, or corporate-member LLC; and (2) the lease carries the verbatim statutory exemption notice (Civ §1947.12(d)(5) / §1946.2(e)(8)). Without the exact notice, the property is fully rent-capped and just-cause-covered regardless of ownership. Number of unrelated roommates does not change this.

Note: the AB 646 flood disclosure itself tells tenants to obtain renter’s + flood insurance — reinforcing the insurance requirement below.

Co-tenancy — the 4-person cohort

One lease, all four named, with an explicit joint-and-several liability clause. Each tenant is individually liable for 100% of rent and damages — not a 1/4 share — so a departure or non-payment doesn’t leave the landlord short. The cohort’s internal split doesn’t bind the landlord; an overpaying roommate seeks contribution from the others. One security deposit for the whole tenancy. Roommate changes go through a landlord-approved lease amendment (departing tenant stays liable until a written release). Occupancy: California’s “2 per bedroom + 1” easily accommodates 4 in any 2-bedroom-plus home.

Insurance

PolicyWhoCoversExcludes
Renter’s (require it)each tenantbelongings, personal liability, loss-of-usethe building, earthquake, flood
DP-3 landlord (Ian must switch to this)landlordstructure + lost renttenant property/liability
HO-3 homeowner’sowner-occupied onlyclaims can be denied once rented out

A California landlord may lawfully require renter’s insurance (in the lease, uniform, non-discriminatory). Best practice: each tenant carries their own policy, $100k–$300k liability, names the landlord as additional interested party (not additional insured), verified before keys. Ian should move from HO-3 to a DP-3 landlord/dwelling policy (covers structure + lost rent), add liability, and — given the Santa Cruz seismic zone and the Rio del Mar flood zone — consider earthquake (CEA) and flood (NFIP) coverage, both excluded from standard policies.

The table above is Scenario A (Ian rents out the whole house). If Ian instead resides there and rents rooms (Scenario B), he keeps HO-3 + a home-sharing endorsement rather than switching to DP-3 — see Tenancy Scenarios - 613 (Whole-House vs Reside-and-Rent-Rooms). Both are shown below.

Insurance — Scenario A (rented out): renter's + DP-3 landlord

Insurance — Scenario B (owner-occupied): HO-3 + home-sharing endorsement

Action checklist for the lease

  1. Decide & insert the AB 1482 exemption notice (if Ian is an individual owner) — verbatim.
  2. One joint-and-several lease, all four named, with a roommate-change clause.
  3. Disclosure packet: Megan’s Law, bed bugs, flood (AB 646), death-3-yr, smoke/CO, lead (if pre-1978), shared-meter utilities.
  4. Require renter’s insurance (each tenant, $100k–$300k, landlord as additional interested party).
  5. Ian: switch HO-3 → DP-3, add liability; price earthquake + flood.
  6. Security deposit ≤ 1 month’s rent.
