Mold in buildings with more than one owner or occupant
Plano is 43 percent renter-occupied, and its apartments, condos and offices sit on the same humid air, shrink-swell clay and rooftop HVAC as its houses. What changes in a shared building is who is responsible, how fast mold spreads between units, and the rules.
Owners of fewer than 10 dwelling units may do their own mold work on their own property. At 10 or more units, which is nearly every apartment community in Plano, mold affecting 25 contiguous square feet or more must be remediated by a TDLR-licensed company, with a separate licensed assessor writing the protocol and clearing the work. Occupants must be told about the project and any biocide used.
Mold in rental housing is a live local issue. In October 2025, as reported by local news, the City of Plano obtained a court order requiring tenants of an apartment complex to vacate over mold, sewage leaks and loss of utilities. Most problems are far smaller, and far easier to fix when a leak is reported early.

If you rent: your rights and the steps that work
Texas has no landlord mold-inspection law. TDLR licenses mold companies but cannot require a landlord to clean or remove mold, and the city does not test private units for mold. What you have is the repair duty in Property Code 92.052: after notice, if your rent is current, the landlord must make a diligent effort to repair or remedy a condition that materially affects the physical health or safety of an ordinary tenant. Mold from a leak can be that condition.
Report it in writing
Email or a letter by certified mail, dated, with photos. If your lease says notices must be written, they must be. Keep copies of everything.
Name the water source
A roof leak, an AC drip, a neighbor's overflow, a slab leak. The landlord fixes the cause; a company that only wipes the wall is not a repair.
Get it documented
If the landlord disputes it, a report from an independent TDLR-licensed assessor is the document that supports your request. You can request assessment quotes through this site.
Use the resources
Plano code compliance, Collin County or Texas health departments, the Texas Attorney General's tenant pages, Texas Tenant Advisor, and the State Bar lawyer referral line. Chapter 92 has specific notice and timing steps before any rent action or lease termination; get advice before taking either.
This section is general information about Texas law, not legal advice. For your situation, talk to a tenant resource or an attorney. See also Texas renters' mold rights.
Property managers, owners and HOA boards
Apartments. On a licensed job the remediation company notifies TDLR five days ahead, or by the next business day in a water-damage emergency, posts project signs, contains the unit with HEPA filtration, and may not remove containment until the assessor's written clearance. Plan for the unit to be out of service through clearance, and for adjoining units to be checked when the source is a shared wall, riser or roof.
Condos and HOAs. Responsibility follows the declaration: common elements and envelope are typically the association's, unit interiors the owner's, and a leak that crosses the line is where disputes start. That is a question for the board's attorney, not a state mold rule. The mold law requires the same licensed process at 25 square feet or more when work is hired out.
Offices, retail and medical. Rooftop units, long duct runs, roof drains and slab leaks under tenant finish-out are the usual causes. The certificate matters at lease turnover and sale, and the same assessor-remediator split applies.
Older stock. About 18 percent of Plano units predate 1980, and Richardson is near 44 percent. Ask whether suspect materials should be sampled for asbestos before tear-out, and about EPA Lead-Safe practices in pre-1978 buildings.
What multifamily and commercial mold work costs
Per-unit pricing follows the same square-foot logic; multi-unit and commercial jobs add containment, after-hours work and tenant coordination.

Typical published ranges, not quotes (Fixr Aug 2025, This Old House Mar 2026, HomeAdvisor 2025). Plano quotes come from the companies, not from this site.
Commercial quotes are built per project and depend on access, occupancy and scope. See the cost guide for the Texas four-part structure.
Documents, insurance and permits
Documents. The Consumer Mold Information Sheet goes to the client and the property owner if they differ. The protocol, work plan, passed clearance report and Certificate of Mold Damage Remediation are the file an owner needs for the insurer, the next buyer and any tenant dispute. Occupations Code 1958.154 requires sellers to give buyers every certificate from the prior five years.
Insurance. Commercial and multifamily policies vary, but the pattern holds: sudden and accidental water events are more often covered, long-term leaks are not, and mold is often limited or excluded unless endorsed. Report promptly and never assume coverage.
Permits. Remediation itself usually needs no Plano permit. Plumbing, roof, HVAC, foundation and wall rebuilds do, by city-registered contractors. Confirm with Plano Building Inspections.
Questions to ask the companies
- Have you worked occupied multifamily buildings, and how do you handle tenant notice?
- Who is the separate licensed assessor, and will adjoining units be checked?
- How will containment keep spores out of shared corridors and the HVAC?
- Will I receive the clearance report and certificate for the owner's file within 10 days?
- License numbers, Consumer Mold Information Sheet and proof of $1 million liability insurance?

Apartment, condo and commercial mold questions
Can my landlord be forced to fix mold in my Plano apartment?
No Texas law requires a landlord to inspect for or clean mold, and TDLR cannot order it. The lever is Property Code 92.052: after notice, if rent is current, a landlord must make a diligent effort to repair a condition that materially affects the physical health or safety of an ordinary tenant. Mold from a leak can be that condition. Send the request in writing and keep copies. Not legal advice.
Who pays for mold remediation, the landlord or the tenant?
Usually the owner, because the owner controls the building and hires the contractors. A tenant can be responsible for conditions the tenant caused, such as a shower left running or a window left open in a storm. Documenting the leak, the date you reported it and the response is what settles the question. For a property with 10 or more units, 25-plus square feet of mold must be handled by a TDLR-licensed remediator.
Does an HOA or condo association handle mold?
It depends on the governing documents and where the mold is. Associations commonly handle common elements and the building envelope, and owners handle the interior of their unit, but the line is drawn by your declaration, not by state mold law. A leak from a shared pipe or the roof usually triggers an association claim. Read the documents and ask the management company in writing; this site does not interpret HOA rules.
What is the 10-unit rule?
Texas Occupations Code 1958.102 lets an owner of residential property with fewer than 10 dwelling units do their own mold work on it without a license, regardless of area. At 10 or more units, mold affecting 25 contiguous square feet or more must be remediated by a licensed company, with a licensed assessor's protocol and clearance. In practice that covers nearly every apartment community in Plano.
Can I break my lease because of mold?
Possibly, under the repair-and-remedy provisions of Property Code chapter 92, which have specific notice steps and timelines. Doing it wrong can leave you owing rent. Get the problem documented, send written notice, and talk to a tenant resource or a lawyer before you stop paying or move out. This is general information, not legal advice.
