California Senate Bill 1318 (“SB 1318”) is one of the most closely watched short-term rental (STR) bills of the 2026 legislative session – especially for owners and operators of vacation rentals in coastal communities like Del Mar, Encinitas, Oceanside, Solana Beach, and other parts of San Diego County.

The bill has raised concerns throughout California’s coastal STR industry because it could significantly change how local governments and the California Coastal Commission enforce restrictions and bans on non-owner-occupied vacation rentals.

Here’s what San Diego STR owners should know about the bill, where it currently stands, and what may happen next.

Update: May 11 Appropriations Hearing — What “Suspense File” Means

On May 11, SB 1318 was heard by the California Senate Appropriations Committee and was officially placed on the committee’s “Suspense File.”

For those unfamiliar with the legislative process, this does not mean the bill has passed or failed.

In California, the Suspense File is commonly used for bills that may have significant fiscal, economic, or statewide policy impacts. Bills placed on suspense are effectively held for additional review and are reconsidered later by the committee in a batch vote.

What this means in practice:

• SB 1318 is still active.
• The bill can still move forward this session.
• The committee may later advance it, amend it, or hold it indefinitely.
• Placement on suspense often signals that lawmakers believe the bill could have broad impacts worth further evaluation.

For STR owners, this means the bill remains something to monitor closely over the coming months.

SB 1318 And the History Behind It

SB 1318 focuses specifically on non-owner-occupied short-term rentals in California’s coastal zone.

The proposed legislation would require the California Coastal Commission to approve local coastal program amendments or coastal development permits that restrict or prohibit non-owner-occupied STRs — regardless of whether those rentals serve visitor demand or tourism needs.

In simpler terms, the bill would make it easier for coastal cities to implement stronger restrictions or outright bans on certain vacation rentals.

Why This Bill Was Introduced

The bill largely stems from ongoing legal disputes between coastal cities, STR operators, and the California Coastal Commission.

Historically, the Coastal Commission has often resisted full bans on STRs in coastal zones because the Coastal Act prioritizes coastal access and visitor-serving accommodations. Courts have repeatedly sided with the idea that STRs can qualify as visitor-serving uses.

Several California coastal cities — including Hermosa Beach, Manhattan Beach, and Santa Barbara — have faced legal and regulatory challenges when attempting to prohibit vacation rentals entirely.

SB 1318 appears intended to give local governments clearer authority to restrict or prohibit non-owner-occupied STRs without needing to prove that sufficient alternative visitor accommodations exist.

Timeline So Far

• Introduced in early 2026 by Senator Benjamin Allen.
• Advanced out of committee in April after amendments.
• Set for Senate Appropriations review in May.
• Placed on the Suspense File on May 11.

The bill remains active and could continue progressing during the 2026 legislative session.

What SB 1318 Could Mean for STR Owners in San Diego

For vacation rental owners in coastal San Diego communities, SB 1318 could have major long-term implications.

Increased Local Authority to Restrict STRs

If passed, the bill could make it significantly easier for coastal cities to:

• Limit the number of STR permits issued
• Restrict non-owner-occupied vacation rentals
• Establish stricter zoning rules
• Phase out certain STR operations over time

Cities that previously faced resistance from the Coastal Commission may gain broader authority to enforce tighter regulations.

Potential Impact on Existing Operators

At this stage, the bill does not automatically eliminate existing STR permits or licenses. However, it could create a more favorable legal pathway for local governments seeking stricter regulations in the future.

That is especially important in highly regulated coastal markets like:

• Del Mar
• Encinitas
• Oceanside
• Solana Beach

Many San Diego coastal cities have already adopted permit caps, operational restrictions, occupancy limits, or minimum stay requirements in recent years.

Why This Matters to Coastal Property Owners

For owners and investors, regulatory uncertainty affects:

• Property values
• Revenue projections
• Financing considerations
• Long-term investment strategy
• Exit planning

While SB 1318 is not law today, it highlights a broader statewide trend toward increased regulation of coastal STRs.

Owners should continue monitoring both state legislation and local city ordinance activity closely.

Other California STR Bills and Regulations to Watch in 2026

SB 1318 is not the only STR-related legislation impacting California operators this year.

SB 346 – STR Platform Data Sharing Requirements

A separate law, SB 346, took effect in 2026 and gives California cities greater authority to require STR platforms like Airbnb and VRBO to share operational data for enforcement purposes.

This could lead to:

• Increased enforcement of local permit requirements
• More aggressive tax collection
• Improved identification of unlicensed STRs

Local Coastal Ordinance Changes

Even outside of statewide legislation, many California coastal cities are continuing to revisit STR regulations.

Recent examples include updated Coastal Commission-approved STR rules in:

• Del Mar
• Encinitas

These updates included permit caps, operational rules, and minimum stay requirements.

Ongoing Enforcement Trends

Across California, cities are increasingly focusing on:

• Illegal STR enforcement
• TOT compliance
• Permit verification
• Neighborhood complaint response
• Platform accountability

Even where no new laws are passed, enforcement activity continues to increase statewide.

Conclusion

SB 1318 represents one of the most significant proposed changes to California coastal STR policy in recent years.

Although the bill has not yet become law, its movement through the legislature signals continued pressure for tighter regulation of non-owner-occupied vacation rentals in coastal communities.

For San Diego STR owners, this is a reminder that the regulatory landscape continues to evolve quickly – especially in coastal zones governed by both local ordinances and the California Coastal Commission.
