Ontario's Short-Term Rentals: The Rules That Matter
Every city handles short-term rentals a little differently. In Ontario, California, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Occupancy Limits
Total occupancy at an Ontario STR, including the host and all guests, may not exceed two times the number of bedrooms. A single dwelling is limited to two concurrent groups or booking transactions, and un-hosted stays are capped at 90 days per year.
Key details: Max Occupancy: 2 x number of bedrooms (incl. host). Concurrent Groups: 2 groups / 2 booking transactions. Un-Hosted Stay Cap: 90 days per calendar year. Hosted Stays: Not limited. Events: Prohibited (weddings, conferences, etc.).
Exceeding the occupancy or two-group limits is a violation of the chapter, drawing administrative civil penalties of $1,000/$2,000/$3,000 per Section 5.03.363.K, with two violations in one year triggering immediate permit suspension under subsection (F).
Insurance Requirements
Ontario STR operators should carry a dedicated short-term rental liability policy. Standard homeowner policies typically exclude STR activity and platform coverage should be treated as a supplement only.
Key details: Homeowner policy: Usually excludes STR. Recommended liability: 500K to 1M dollars. Platform coverage: Supplement only. Disclosure to insurer: Required. Proof of coverage: Keep on file.
Contact your local code enforcement office for specific penalty information.
Ontario is more permissive than most cities when it comes to insurance requirements. That said, there are still limits.
Night Caps
Ontario distinguishes between hosted and non-hosted STRs and may cap annual rental nights for non-hosted whole-home rentals. Operators must track bookings and retain records for city review.
Key details: Common cap range: 90 to 180 nights/year. Hosted stays: Often uncapped. Non-hosted whole-home: Typically capped. Recordkeeping: Required. Enforcement: Permit suspension.
Contact your local code enforcement office for specific penalty information.
Registration Rules
Ontario STR registration requires a Planning-issued permit, Finance TOT certificate, and business license. Annual renewal, a 24-hour contact, and safety inspection items are standard conditions.
Key details: Required registrations: Permit, TOT, business license. Portal: City Citizen Portal. Renewal: Annual. Local contact: 24-hour availability. Safety items: Smoke/CO/extinguisher.
Contact your local code enforcement office for specific penalty information.
This is not one of those rules that cities tend to ignore. Ontario actively enforces its registration rules requirements.
Noise Rules
STR guests must comply with Ontario Municipal Code Chapter 29 noise rules including 10 PM to 7 AM quiet hours. Operators are responsible for guest conduct and repeat noise violations can cost them the permit.
Key details: Quiet hours: 10 PM to 7 AM. Code basis: OMC Ch. 29 Sec. 5-29.07. Operator liability: Yes, for guest conduct. Local contact: 24-hour number required. Repeat violations: Permit suspension risk.

Permit Requirements
Ontario requires a Short-Term Rental Permit and a business license before any dwelling under 30 days is rented. Only the host's primary residence qualifies, and non-owner-occupied vacation rentals are prohibited.
Key details: Code Section: Development Code 5.03.363(B). Permit Term: 12 months, annual inspection to renew. Primary Residence: Required; vacation rentals prohibited. Business License: Required (Title 3, Chapter 1, OMC). Allowed Zones: AR-2, RE-2/4, LDR-5, MDR, HDR-45, MU zones.
Operating without a valid permit and business license is prohibited; advertising is prima facie evidence of operation. A violation is a public nuisance and a misdemeanor, with administrative civil penalties of $1,000 (first), $2,000 (second), and $3,000 (third and subsequent) per Section 5.03.363.K.
This is one of the stricter rules in Ontario's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Taxes & Fees
Ontario charges a Transient Occupancy Tax on short-term stays under 30 days. Operators must register for a TOT certificate, collect the tax, file returns, and pay an annual STR permit fee.
Key details: Tax type: Transient Occupancy Tax. Applies to: Stays under 30 days. TOT certificate: Required before listing. Filing cadence: Monthly or quarterly. Permit fee: Annual, plus business license.
Contact your local code enforcement office for specific penalty information.

Key details: Primary requirement: On-site parking first. Street sweeping: Must be followed. RVs and trailers: Overnight restricted. Blocking driveways: Prohibited, towable. House rules: Must specify parking.
