If you are a small business owner in San Diego, the roof over your business is just as important as the one over your home. Receiving a legal eviction notice, such as a 3-day or 10-day notice, is a high-stakes moment that can feel overwhelming. The notice can be a precursor to an unlawful detainer lawsuit. An unlawful detainer is the court case a landlord may file only after the notice period expires and the tenant has not complied or moved out. You may be worried about your inventory, your employees, and the years of hard work you’ve poured into your company.

The landscape of commercial evictions in California has shifted significantly with the arrival of new laws like SB 1103 and AB 2347. These updates were designed to give smaller tenants a fighting chance, but they come with technical requirements that you must navigate perfectly to protect your rights.

At the Law Office of Andrew H. Griffin, III, APC, we have spent over 40 years helping the San Diego community navigate these complex legal waters. Because Andrew Griffin is both a California-licensed real estate broker and an experienced attorney, our firm offers a unique dual perspective that most traditional law firms cannot match. Whether you are a landlord trying to follow the new rules or a tenant fighting to stay in your space, you deserve a guide who understands both the law and the market.

What is the New 10-Court-Day Response Rule?

For years, commercial tenants in San Diego only had five days to respond to an unlawful detainer summons and complaint. In the world of business, five days is barely enough time to find a file, let alone hire a commercial eviction lawyer and prepare a defense.

Under the new rule (Assembly Bill 2347), you now generally have 10 court days to file a written response with the court after you are served with the actual unlawful detainer lawsuit papers. This is a critical distinction. A landlord’s legal eviction notice, such as a 3-day notice or 10-day notice, is a pre-lawsuit demand. The 10-court-day response deadline does not start when that notice is served. It starts only after the landlord files the unlawful detainer case and you are served with the court summons and complaint. While this is an improvement, it is still a remarkably tight window.

It is important to remember:

  • Court days are not calendar days. Weekends and court holidays do not count toward your 10-day limit.
  • The 10-day rule applies to the lawsuit, not the notice. A legal notice gives you a deadline to pay, perform lease obligations, or vacate. The unlawful detainer is the separate court action that may come later if the issue is not resolved.
  • Missing the deadline is critical. If you fail to file a response within those 10 court days after service of the summons and complaint, the landlord can request a "default judgment." This allows them to move quickly to obtain a writ of possession and have the Sheriff remove you from the property.
  • The response must be formal. You cannot simply call the landlord or send an email. You must file a valid responsive pleading, such as an Answer or a Demurrer, with the San Diego County Superior Court.

If you have been served with unlawful detainer court papers, the clock is already ticking. You should contact a San Diego eviction attorney immediately to ensure your response is filed correctly and on time.

Are You a "Qualified Commercial Tenant" Under SB 1103?

Starting in 2025, the Commercial Tenant Protection Act (SB 1103) introduced sweeping protections for a specific group known as "Qualified Commercial Tenants" (QCTs). This law is a game-changer for the "mom-and-pop" shops that make San Diego County so vibrant.

You are likely a Qualified Commercial Tenant if your business falls into one of these categories:

  1. Microenterprises: Businesses with five or fewer employees.
  2. Small Nonprofits: Nonprofits with fewer than 20 employees.
  3. Small Restaurants: Certain dining establishments with fewer than 10 employees.

The Catch: These protections are not automatic. To benefit from SB 1103, you must self-identify as a QCT in writing to your landlord. You must do this before signing a lease (for leases over 30 days) and then re-certify this status annually. If you haven't provided this notice yet, it's a step you should take immediately with the help of an eviction attorney in San Diego.

How Do Rent Spike Protections Work?

Many San Diego business owners have faced the "rent spike": a sudden, massive increase in monthly rent that makes staying in business impossible. SB 1103 addresses this by requiring longer notice periods for significant increases.

  • Increases of 10% or less: The landlord must provide at least 30 days’ written notice.
  • Increases of more than 10%: The landlord must provide at least 90 days’ written notice.

This 10% threshold includes all cumulative increases made within the prior 12-month period. If your landlord tries to raise your rent by 15% but only gives you 30 days’ notice, they may be in violation of the law. This can be used as a powerful tool in negotiations or as a defense if the landlord attempts to evict you for not paying the increased amount.

Hidden CAM Fees: What Landlords Must Now Disclose

Detailed CAM fee and building operating cost documentation

One of the most frustrating parts of a commercial lease is the "Common Area Maintenance" (CAM) fee or building operating costs. Often, these fees are opaque, leaving tenants wondering exactly what they are paying for.

For Qualified Commercial Tenants, SB 1103 brings much-needed transparency:

  • Supporting Documentation: Landlords can no longer just send a bill for CAM fees. They must provide an itemized quote, contract, or receipt from the service provider.
  • Allocation Formulas: The landlord must show exactly how your share of the costs was calculated.
  • Signed Attestation: The landlord must sign and date a statement swearing that the costs are true and correct.

If a landlord attempts to evict you for non-payment of these operating costs but has failed to provide this required documentation, you may have a strong affirmative defense in court. Our firm has seen many cases where landlords skip these steps, and we use that lack of compliance to protect our clients' businesses.

Translation Rights: Why Your Spanish-Negotiated Lease Matters

San Diego is a diverse community, and many business deals are conducted in languages other than English. If your lease was primarily negotiated in Spanish, Chinese, Tagalog, Vietnamese, or Korean, SB 1103 grants you significant new rights.

If you are a Qualified Commercial Tenant and your lease was negotiated in one of these languages, the landlord must provide a full, translated copy of the lease before you sign it.

If they failed to do this:

  • Right to Rescind: You may have the right to rescind (cancel) the lease entirely.
  • Bilingual Notices: Any legal eviction notice or rent increase notice must also be provided in the language used for negotiation.

At the Law Office of Andrew H. Griffin, III, APC, we offer bilingual services in English and Spanish. We understand that legal jargon is hard enough to navigate in your first language: it shouldn't be a barrier to your business's success. If you feel you were treated unfairly because of a language barrier during your lease signing, we are here to help.
