Overview: Are Short-Term Rentals Allowed in San Marcos, California?

Explicit answer: In San Marcos, California, short-term rentals are not permitted in residential zones unless explicitly allowed by a city-approved Specific Plan. If the property is located within a Specific Plan area that permits short-term rentals, transient occupancy tax (TOT) is payable when the property is used as a short-term rental. San Marcos allows one narrow path to lodging in residential areas: a Bed & Breakfast use may qualify for a Conditional Use Permit (CUP) in a limited number of zoning districts if it meets the city’s land use definition (single living unit serving as the owner/manager’s residence plus no more than five guest rooms offering temporary lodging with or without meals).

Tax note: San Marcos assesses a 10% Transient Occupancy Tax (TOT) on lodging rentals of 30 days or less. Operators must register, collect, and remit TOT on a quarterly basis. TOT applies whether the unit is operated as an STR or a permitted Bed & Breakfast.

This guide is written for STR investors and professional operators. It focuses on city-level rules, uses only San Marcos, California sources, and provides state-level context only where relevant to local operations.

How to Start a Short-Term Rental Business in San Marcos (CA)

1. Determine zoning eligibility and pathways

   • Confirm the subject property is not in a standard residential zone; most residential zones prohibit STRs unless the property lies within a Specific Plan area that expressly allows short-term rentals.
   • If the property could qualify as a Bed & Breakfast:
     • Verify the proposed use aligns with the city’s definition: a single-family dwelling with one living unit serving as the owner/manager’s residence, providing no more than five guest rooms for temporary lodging (with or without meals).
     • Confirm the subject property is in a zoning district where a CUP for lodging is accepted under city policy.
     • Proceed with a CUP application if eligible.
   • Action: Contact the Planning Division for zoning confirmation and CUP eligibility, and determine whether any applicable Specific Plan governs STRs for your parcel.

2. Register for Transient Occupancy Tax (TOT)

   • If the use is a permitted short-term rental (Specific Plan area) or an approved Bed & Breakfast, enroll with the City to collect and remit TOT.
   • TOT rate: 10% of gross room rental charges.
   • Remittance cadence: Quarterly.
   • Enroll via the city’s online TOT portal and review the TOT return form (both linked below).

3. Operate with compliance in mind

   • For Bed & Breakfast operations approved via CUP, continue to maintain compliance with all use conditions, safety standards, and ongoing TOT obligations.
   • Monitor municipal code updates and city guidance for any changes to STR policies, CUP standards, or TOT procedures.

Tip: Because San Marcos severely restricts STRs in residential zones, many investors consider alternative strategies such as conventional long-term rentals, acquiring properties in Specific Plan areas that permit STRs, or repurposing assets for uses aligned with permitted zoning.

Notes and Practical Investor Considerations

• Market feasibility: Because STRs are prohibited in most residential zones, inventory within Specific Plan areas is the primary city-aligned opportunity. Parcels outside those areas should be evaluated for long-term rental, owner-user B&B potential via CUP, or alternative development strategies.
• Compliance costs and timeline: TOT registration is straightforward; obtaining a CUP for a Bed & Breakfast requires planning review, public noticing, and potential conditions. Plan for application lead times and ongoing operational compliance.
• Risk management: Do not advertise or operate STRs in residential zones absent Specific Plan approval. City enforcement can include code enforcement actions and tax liabilities for unregistered or prohibited operations.
• Ongoing monitoring: San Marcos’ STR policy landscape may evolve; watch city announcements and refer to the Transient Occupancy Tax page for rule changes.
