Modesto’s position in the Central Valley, surrounded by vast agricultural lands and experiencing severe summer heat, drives mice, ants, and Turkestan cockroaches indoors seeking water and shelter. When these pests invade older apartment complexes or rental homes, landlords frequently attempt to shift the financial burden of extermination onto tenants, citing “tenant hygiene” or the agricultural environment as the cause.
However, Modesto renters are powerfully protected. Through the city’s proactive Rental Housing Safety Program (RHSP) and state habitability laws, landlords face strict enforcement for health hazards. If you are dealing with a severe infestation of roaches, rats, or bed bugs, understanding the intersection of the California Civil Code and Modesto municipal ordinances is your best defense against illegal pest control fees.

2. What is the Pest Control Law in California?
If you are wondering, “Are landlords typically responsible for pest control?” the answer is an overwhelming yes. Under the California Warranty of Habitability (Civil Code § 1941.1), landlords are legally obligated to maintain rental properties in a livable, safe, and sanitary condition. This explicitly includes providing “a building, grounds, and appurtenances… kept in every part clean, sanitary, and free from all accumulations of debris, filth, rubbish, garbage, rodents, and vermin.”
What are Uninhabitable Living Conditions?
Under this law, a property is legally classified as uninhabitable if it substantially lacks weatherproofing, has a severe lack of sanitation, or hosts an active infestation of rodents, cockroaches, or bed bugs. Unless the landlord can definitively prove with documentation from a licensed pest control operator that a tenant’s negligent actions caused the infestation, the financial responsibility for extermination falls strictly on the property owner.
Neighboring Jurisdiction Warning: Don’t Assume the Law
While the City of Modesto aggressively enforces its RHSP ordinance, moving just outside the city limits into unincorporated Stanislaus County or neighboring towns changes the enforcement agencies and local protections entirely. If you live in an adjacent city, you must report violations to their specific departments:
- Ceres Tenant Rights: Handled by City of Ceres Code Enforcement.
- Riverbank Tenant Rights: Managed by Riverbank Code Enforcement.
Never withhold rent based on an internet template without first establishing official documentation through your specific local code enforcement agency.
3. Cockroaches in Apartment Law: Who Pays for the Hardest Pests?
If you ask a Central Valley exterminator, “What is the hardest pest to get rid of?” in apartments, it is the German Cockroach. Because they travel effortlessly through shared plumbing voids and electrical conduits between units, California law recognizes that one tenant cannot control them alone. A Modesto landlord cannot charge an individual tenant for cockroach extermination if the insects are migrating from common areas, neighboring units, or unsealed exterior walls.
4. The “Pest Addendum” & “Deep Clean” Extortion
“Any provision of a lease or rental agreement of a dwelling by which the lessee agrees to modify or waive… his rights or remedies under Section 1941.1… shall be void as contrary to public policy.”
5. Modesto’s Rental Housing Safety Program (RHSP)
In Modesto, tenants have powerful local municipal support designed to prevent slumlords from allowing housing to deteriorate into unsafe, pest-infested conditions.
How the RHSP Protects You:
- Proactive Inspections (Ordinance 3703): Modesto requires all residential rental properties older than 10 years to register with the city. Approximately 10% of all registered units are randomly selected each year for a safety audit conducted by City of Modesto Enforcement officers.
- Landlord Accountability: If an inspector discovers a severe pest infestation or structural failing during an RHSP audit or a tenant complaint, the property owner is held financially responsible for repairs and can face significant municipal fines.
- Anti-Retaliation: Complaining to Modesto Code Enforcement about habitability issues is legally protected under state law. Landlords cannot retaliate by serving an eviction notice.
6. Section 8 & SRHA Housing Leverage
If you receive housing assistance through the Stanislaus Regional Housing Authority (SRHA), you have additional leverage. Subsidized housing must pass strict Housing Quality Standards (HQS) inspections.
A severe roach, rat, or bed bug infestation is an automatic violation. If your landlord refuses to exterminate, contact your Housing Specialist or call the SRHA at (209) 557-2000. The Housing Authority has the power to freeze the landlord’s housing assistance payments until the pest issue is certified as completely resolved.
7. How to Report Infestations Properly
To successfully force a landlord to pay for extermination, follow these documentation steps before requesting an inspection:
- Submit Certified Written Notice: You must provide the landlord with a clear, written request for repairs. Use our official generator below. Text messages carry far less legal weight.
- Contact Modesto Code Enforcement: If the landlord ignores you, call the Modesto Code Enforcement Unit at (209) 577-5250. You can also report via the GoModesto! app. If the inspector finds active vermin or building blight, they will issue a formal Notice to the property owner.
- Watch for the ‘Handyman Loophole’: It is illegal for a landlord to send an unlicensed maintenance worker to apply restricted commercial pesticides inside an occupied unit. If a handyman shows up with a chemical pump sprayer, photograph them and report the management to the California Structural Pest Control Board.

Yes. Under Civil Code § 1954.602, a landlord cannot show, rent, or lease a unit that they know has a current bed bug infestation. If bed bugs are found immediately after move-in, the law generally presumes the unit was already infested.
