Overview: Are Short-Term Rentals Allowed in Princeton, NJ?

YES, short-term rentals are currently allowed in Princeton, NJ, but significant regulatory changes are underway. As of October 2025, Princeton is developing a comprehensive short-term rental ordinance that is expected to be implemented by early 2026. Currently, there are an estimated 125-150 short-term rental properties operating in town without formal registration requirements.

The proposed regulations aim to balance four primary objectives:

• Ensuring public safety through inspections and clear requirements
• Preserving neighborhood character
• Maintaining housing availability for long-term residents
• Balancing the interests of property owners, visitors, and the broader community

How to Start a Short-Term Rental Business in Princeton

Current Market Conditions (October 2025)

Before the new ordinance takes effect in early 2026, you can operate a short-term rental without municipal permits. However, this window is closing rapidly. The municipality is moving quickly to implement regulations after years of discussion.

Post-Ordinance Requirements (Early 2026)

Once the ordinance takes effect, starting a short-term rental business will require:

1. Permit Application Process: Similar to the municipality's existing long-term rental process
2. Registration: Through the municipality's software platform (OpenGov)
3. Safety Inspections: Required before operation
4. Annual Renewals: Mandatory for continued operation
5. Compliance Monitoring: Using Deckard platform for tracking

Principal Residence Requirements

Princeton is considering four options for principal residence requirements:

• Option 1: Require all STRs to be owner's principal residence immediately upon passage
• Option 2: 12-to-24-month phase-out period for existing non-principal residence rentals
• Option 3: Allow existing non-principal residence STRs to continue until property sale/transfer (current draft preference)
• Option 4: No principal residence requirement (generates highest tax revenue but contradicts stated goals)

Important Note for Investors: The regulatory landscape for short-term rentals in Princeton is rapidly evolving. While STRs are currently permitted without formal registration, the comprehensive ordinance expected in early 2026 will significantly change requirements. Investors should monitor municipal communications closely and consider the principal residence requirement options when making investment decisions. The 3% occupancy tax and registration requirements will impact profitability, while the principal residence policy will determine market access for non-owner-occupied properties.
