The Lease Amendment You Never Signed: When Tenants Run a Business From Your Rental
Here's a scenario I've heard more than once from owners across Collin and Denton Counties: a landlord gets a call from their HOA about "excessive commercial traffic" at their rental. They pull out their lease. Nothing in it authorizes a business. Then they dig deeper and find an addendum they never saw, never signed, and never approved — one that somehow allowed a home-based activity they would have flatly rejected.
That kind of situation is not a freak accident. It's what happens when lease changes go undocumented and owner approval isn't built into the process.
This post covers the real exposure a tenant's home business creates, what Texas law does and doesn't restrict, and why written owner approval on every lease modification isn't optional at DWC.
The Businesses Tenants Run From Rentals (More Common Than You Think)
Home daycares. Hair and nail salons. Music and tutoring studios. Auto detailing. Dog grooming. Food prep and catering out of the kitchen. In-home personal training. These are not hypotheticals. They're the kinds of operations that show up in residential rentals across Frisco, Prosper, and Plano every year.
Some tenants are fully transparent about it. Others aren't. And a third group operates under the assumption that "working from home" is the same thing as "running a client-facing business from home." It isn't.
The distinction matters because each of these activities changes the risk profile of your property. A tenant who does remote accounting from the spare bedroom is not the same as a tenant who runs a licensed home daycare with eight children arriving at 7 a.m. in a Phillips Creek Ranch home with HOA-governed quiet hours and parking rules.
The number that should get your attention: Texas DFPS allows a licensed home daycare to serve up to 12 children in a residential property. Twelve children, multiple drop-offs and pick-ups daily, in your rental — with your name on the deed.
The Liability Problem Your Insurance Company Won't Overlook
Standard landlord insurance covers the structure and your liability as a property owner. What it typically does not cover is liability arising from a tenant's commercial operation on the premises.
If a child is injured at a tenant-operated daycare, if a salon client slips on the front walkway, if a customer's car is damaged during an at-home detailing job — your carrier will ask whether the property was being used for a commercial purpose. If the answer is yes and your policy is written for residential use, you may be looking at a coverage denial.
I've talked to owners in Prosper and Celina who didn't know their policy had a commercial-use exclusion until they needed to file a claim. By then, it's too late to fix it retroactively.
The tenant's business liability policy (if they even have one) is not your policy. It doesn't protect you. And in most cases, a home daycare or salon operator running out of a rental either has minimal coverage or none at all. The liability exposure lands on whoever owns the property.
This connects directly to how you read your owner financials. If you want a better picture of what's being managed and documented on your behalf, the post on property management owner statements walks through exactly what to look for.
HOA Communities: The Commercial-Use Trigger Most Tenants Don't Expect
If your rental is in a master-planned HOA community, the deed restrictions almost certainly prohibit commercial use of residential lots. This applies whether it's the owner or a tenant operating the business.
The HOA doesn't care whose name is on the lease. They care whose name is on the deed. That's yours.
In communities like Star Trail in Prosper or Windsong Ranch in Aubrey, HOA enforcement can move fast once a neighbor files a complaint. Increased foot traffic, commercial signage (even a small one), delivery vehicles, or parking overflow are all triggers. A single violation notice can escalate to fines of $50 to $200 per day in some Collin County HOAs. Unresolved, that becomes a lien.
The deeper issue is that most tenants operating a home business don't research HOA rules before they set up. They assume that if the lease doesn't specifically prohibit it, it's allowed. Texas lease law doesn't work that way, and neither do deed restrictions.
If you're already managing HOA risk on a rental, the post on HOA violations on rental properties in Texas covers the enforcement process and how landlords keep getting caught off guard.
What Texas Law Allows — and What Your Lease Should Say
Texas doesn't have a blanket prohibition on tenants running businesses from rental properties. Whether it's allowed depends entirely on three layers: local zoning, HOA deed restrictions, and the lease itself.
Zoning in most Frisco residential districts limits commercial activity, especially any use that generates regular customer traffic. But zoning enforcement is complaint-driven and inconsistent. The more reliable protection is contractual — what your lease actually says.
A well-drafted Texas residential lease should include:
- A use clause limiting the property to residential purposes only
- A written approval requirement for any business activity that generates customer traffic
- A prohibition on commercial signage on the property or in windows
- Language tying commercial activity violations to material breach and termination rights
The critical phrase is "written approval." An oral conversation, a text, an email exchange with no documented owner response — none of that protects you the way a signed addendum does. If your lease doesn't require written owner sign-off on business use, it has a gap.
The Red Flags That a Unit Has Gone Commercial
I tell every owner I work with to pay attention to a short list of signals during routine inspections and HOA monitoring:
On the property:
- Signage, even small window signs or door placards
- Parking overflow that doesn't match a residential household
- Equipment deliveries or frequent commercial vehicle visits
- Modifications to the space (salon chairs, childproofing hardware, installed mirrors)
On paper:
- Business registration listed at your property address (this is publicly searchable through the Texas Secretary of State)
- A DBA or LLC using your address
- Utility usage that spikes beyond a residential baseline
Any one of these alone isn't proof. The combination of two or three is worth a conversation with the tenant immediately. I've seen situations where tenants didn't realize they'd created a problem. I've also seen situations where they knew exactly what they were doing and hoped nobody noticed.
Why DWC Requires Written Owner Approval on Every Lease Modification
No lease amendment leaves our office without the owner's documented sign-off. That's not a preference. It's policy.
The reason is simple: the lease is a legal contract between two parties, and you are one of them. Any change to that contract changes your rights and obligations. A property manager who modifies lease terms without owner approval isn't acting as your agent. They're acting unilaterally, and the liability for whatever that change enables stays with you.
At DWC, our process is:
- Tenant requests or raises an issue that might require a lease modification
- We document the request and evaluate it against your property's use restrictions, HOA rules, and insurance requirements
- We present it to you with a clear recommendation
- You approve or decline in writing before anything changes
That's it. No shortcuts. No "I'll loop you in later." The owner account is where every decision of consequence gets recorded — and if you've ever wondered why some property managers end up with difficult client relationships, it usually traces back to decisions made without proper documentation.
If you own a rental in a Phillips Creek Ranch, Star Trail, or any HOA community in Frisco or Collin County and you're not certain your current lease protects you from unauthorized commercial use, I'd suggest a conversation before your next renewal cycle.

Frequently Asked Questions
Can my tenant run a business out of my rental property in Texas?
It depends on three things: local zoning, HOA deed restrictions, and what your lease says. Texas has no blanket prohibition, but most residential zoning districts in Frisco, Prosper, and Plano restrict customer-traffic-generating commercial activity. Your lease should require written owner approval before any business use begins.
Can a tenant operate a daycare in my rental without my permission?
Not legally if your lease includes a residential-use-only clause. Texas DFPS can license a home daycare serving up to 12 children in a residential property. That's 12 children generating daily drop-off and pick-up traffic at your rental. Without explicit written owner approval, that operation is a lease violation and potentially an HOA violation.
Who is liable if a tenant's home business causes damage or injury?
Your exposure as the property owner is real. Standard landlord insurance policies typically exclude liability arising from commercial operations on the premises. If a client is injured during a business activity and your policy has a commercial-use exclusion, you may face a coverage denial. The tenant's business liability coverage, if they have any, does not protect you.
Can my HOA stop a tenant from running a business?
Yes. Most HOA deed restrictions in master-planned communities like Star Trail and Windsong Ranch prohibit commercial use of residential lots. The HOA holds the deed owner accountable, not the tenant. Violations can result in fines from $50 to $200 per day, and unresolved fines can become liens against your property.
How do I make sure no lease changes happen without my approval?
Your management agreement and lease process need to require documented owner sign-off on every amendment before it takes effect. At DWC, nothing changes without written owner approval. That process is documented, timestamped, and retained for the life of the tenancy.
Does a home business void my landlord insurance?
Not automatically, but it can trigger a coverage exclusion when you need it most. Commercial use of a residential property is a material change in risk. If your carrier isn't informed and a claim arises from a business-related incident, you risk a partial or full denial. Review your policy's commercial-use language before your next renewal.
