Arizona commercial landlord tenant law is not a single statute. The Arizona Residential Landlord and Tenant Act (ARLTA) covers dwellings only, and there is no commercial equivalent, so leases for office, retail, and industrial space are governed by general contract law and a handful of provisions scattered through Titles 12, 33, and 44 of the Arizona Revised Statutes. In practical terms, the lease itself is the law between the parties, and the terms you sign are the terms you live with.
Why the Residential Protections Do Not Apply
Almost every baseline right a residential tenant takes for granted is missing on the commercial side. The ARLTA requires landlords to maintain habitable conditions, return security deposits with an itemized statement within 14 business days, allow at least five days’ grace before charging late fees, and follow specific eviction procedures. None of that reaches commercial tenants. The statute was written for dwelling units, and its exclusion list in A.R.S. ยง 33-1308 does not mention commercial properties because the act was never drafted to cover them.1Arizona Department of Housing. Arizona Residential Landlord and Tenant Act
The consequence is that a commercial lease can lawfully include terms that would be void in a residential context. No statutory cap on security deposits. No mandatory grace period for late rent. No timeline for returning deposits. No automatic duty to keep the building in good repair. Courts presume that two businesses have roughly equal sophistication and enforce what the contract says unless it crosses into unconscionability or violates public policy. That presumption puts the burden on tenants to negotiate protections into the lease rather than expect a statute to supply them later.
Putting the Lease in Writing
Arizona’s statute of frauds requires any lease longer than one year to be in writing.2Arizona Legislature. Arizona Code 44-101 – Statute of Frauds An oral six-month agreement can be enforceable, but proving its terms without a written record is difficult. Any serious commercial deal should be documented.
A workable commercial lease covers at minimum: rent and payment schedule, permitted uses of the space, maintenance and repair responsibilities, insurance requirements, renewal and termination options, and what happens on default. Arizona courts enforce these terms as written, so vague or missing provisions hurt whichever party needed the protection.
If the lease includes a personal guarantee, the individual signing it is personally liable for unpaid rent and other obligations even if the business entity folds. Landlords often require guarantees when they are not confident in a tenant’s business credit, and Arizona courts consistently enforce them. Signing without understanding the exposure is one of the most costly mistakes a small business owner can make.
Security Deposits
Residential landlords cannot demand more than one and one-half months’ rent as a security deposit and must return it with an itemized statement within 14 business days of move-out.3Arizona Legislature. Arizona Code 33-1321 – Security Deposits Neither restriction applies commercially. A commercial landlord can demand three months, six months, or more, and no statute sets a deadline for returning it.
Because the lease controls, tenants should negotiate deposit terms with the same care as rent. Watch the conditions that let the landlord keep the deposit, particularly early-termination clauses declaring it “forfeited.” Courts enforce a forfeiture clause if it reasonably estimates the landlord’s anticipated damages, and strike it down if it functions as a penalty unrelated to actual harm. That line is blurry enough to warrant clear drafting. The lease should also require an itemized breakdown of any deductions; without it, a tenant disputing charges has to rely on ordinary breach-of-contract litigation.
Rent, CAM Charges, and Transaction Privilege Tax
Arizona has no rent control for commercial properties. Landlords can structure rent as flat monthly amounts, percentage rent tied to gross revenue, stepped increases, or adjustments pegged to an index like CPI. Courts enforce escalation clauses as written, so a tenant who signs a lease with aggressive annual bumps has little recourse absent unconscionability, which is a high bar.
Many commercial leases require tenants to pay a share of common area maintenance (CAM) covering landscaping, parking lot upkeep, security, and shared utilities. CAM is a frequent source of disputes because tenants often have limited visibility into what the landlord actually spends. If your lease has CAM obligations, negotiate an audit right that lets you or an accountant you hire review the landlord’s books and invoices within a defined window after the annual reconciliation. Without that right written in, you pay whatever the landlord bills.
Arizona also imposes a transaction privilege tax (TPT) on the business of leasing commercial real property. The state-level rate for commercial leases is currently zero, but five counties charge their own county-level TPT on commercial rent: Coconino (0.3%), Gila (0.5%), Maricopa (0.5%), Pima (0.5%), and Pinal (0.5%).4Arizona Department of Revenue. Transaction Privilege and Other Tax Rate Tables Cities may add their own rates on top. The tax is technically imposed on the landlord, but most leases pass it through to the tenant as an additional charge, and the items subject to TPT include base rent, property tax reimbursements, insurance reimbursements, CAM payments, and payments for leasehold improvements.5Arizona Department of Revenue. Commercial Lease Budget for TPT as a line item alongside rent and CAM.
Maintenance, Repairs, and NNN Leases
Residential landlords must keep the property habitable regardless of the lease. Commercial landlords owe only what the lease says they owe. If the lease is silent on a repair category, courts look at industry norms and the nature of the lease to fill the gap, but that is an expensive way to resolve a question a single paragraph could settle.
Triple net (NNN) leases are common in Arizona and shift the biggest costs onto the tenant. Under a typical NNN structure, the tenant pays rent plus property taxes, building insurance, and repair expenses, which can include roof replacements, parking lot resurfacing, and HVAC overhauls. Get an independent building inspection before signing so you know what deferred maintenance you are inheriting.
ADA compliance is another allocation question. Owners are generally responsible for common areas and the building structure, while tenants often bear responsibility for ADA modifications tied to their specific use. A restaurant that reconfigures the interior in a way that affects wheelchair access typically pays to bring the space up to code. Spell this out in the lease rather than leaving it to default assumptions.
Subleasing and Assignment
Arizona courts follow the Restatement (Second) of Property rule: when a lease requires the landlord’s consent to sublease or assign, the landlord cannot withhold that consent unreasonably unless the lease explicitly gives the landlord sole and absolute discretion to refuse.6CaseMine. Tucson Medical Center v. Zoslow A generic consent clause without that reservation subjects the landlord to a reasonableness standard.
Legitimate reasons to refuse include the proposed subtenant’s financial weakness, an incompatible business use, or a likely drop in percentage rent. Illegitimate reasons include wanting to extract higher rent from a new tenant or simple dissatisfaction with the original deal. A tenant seeking consent should document the proposed subtenant’s qualifications thoroughly. A landlord who wants the right to refuse for any reason must say so in clear terms.
Landlord Remedies When a Tenant Defaults
When a commercial tenant stops paying or violates another term, the landlord can pursue money damages, terminate the lease, and reclaim the property. Arizona law allows a landlord to reenter and take possession once rent is in arrears for five days or when the tenant violates any lease provision, and it lets the landlord skip formal demand and file directly for possession.7Arizona Legislature. Arizona Code 33-361 – Violation of Lease by Tenant; Right of Landlord to Reenter; Summary Action for Recovery of Premises
If a tenant abandons the space, the landlord cannot let rent accrue and then sue for the full remaining balance. Arizona courts have held since 1975 that commercial landlords must make reasonable efforts to re-lease the property at a fair rental rate.8CaseMine. Dushoff v. Phoenix Company That means advertising, listing with brokers, and holding showings. The landlord does not have to accept the first applicant at any price, but leaving the space empty for months without trying to fill it undercuts a damages claim. Once a replacement moves in, the original tenant’s rent obligation stops accruing for that period. The breaching tenant bears the burden of proving the landlord failed to mitigate.
The Forcible Detainer Process
Commercial eviction in Arizona runs through the forcible detainer statute. A forcible detainer exists when a tenant whose tenancy has ended refuses to leave after receiving a written demand for possession, or when a tenant at will or by sufferance holds over after termination.9Arizona Legislature. Arizona Code 12-1173 – Definition of Forcible Detainer; Substitution of Parties The landlord must give proper written notice and wait until the day after the notice period expires before filing.10Arizona Judicial Branch. Eviction Actions
If the court rules for the landlord, it enters a judgment for possession along with any unpaid rent, damages, and attorney fees. The writ of restitution, which authorizes law enforcement to remove the tenant, cannot issue until five calendar days after judgment.11Arizona Legislature. Arizona Code 12-1178 – Judgment; Writ of Restitution Once issued, it must be enforced promptly and cannot be delayed by a motion to set aside the judgment unless a judge finds good cause.
No statute gives commercial tenants a mandatory cure period. Whether a tenant gets time to fix a default before the landlord can act depends entirely on the lease. Some provide 10 or 30 days to cure; others provide none. A tenant negotiating a lease should push for a reasonable cure period on non-monetary defaults, because without one, a single violation can trigger an eviction the next day.
Tenant Early Termination and Landlord Breach
Walking away early is almost always expensive. Most leases require the tenant to keep paying rent through the end of the term or until the landlord finds a replacement, whichever comes first. Some include an early termination option with a buyout fee ranging from a few months’ rent to the full remaining balance. Without that option, the tenant’s only exit is negotiating a surrender or subleasing the space.
A tenant may have grounds to terminate without penalty if the landlord materially breaches the lease. Wrongfully denying access to the premises is a common example. Refusing to make repairs the lease requires the landlord to handle can also qualify. Some leases give the tenant a repair-and-deduct right, but courts typically require the tenant to follow the notice-and-cure procedure the lease specifies before acting unilaterally. Skipping those steps can turn a valid grievance into a lease violation, and tenants who self-help their way out without solid documentation often end up liable for the damages they were trying to avoid.
