CAM Dispute Timeline: How Long Does a CAM Dispute Take?
The honest answer is anywhere from six weeks to two years, depending on how cooperative your landlord is and whether the dispute ends up in mediation or litigation. Most CAM disputes resolve faster than people expect — the ones that drag on typically do so because of poor process on one or both sides, not because the legal system is slow.
Here is a phase-by-phase breakdown with realistic timelines.

1. Phase 1: Audit and Calculation (2–6 Weeks)
Before you can send a demand letter, you need to know exactly what you are claiming. This phase involves:
- Gathering your lease, amendments, and reconciliation statements
- Identifying the specific overcharge categories (management fee, CapEx, pro-rata share, etc.)
- Calculating the dollar amount for each item
- Verifying that your dispute window is still open
A tenant doing this manually with a spreadsheet can typically complete this phase in two to four weeks. A professional audit firm can be faster but costs more. Automated tools like CamAudit can flag the overcharge categories in minutes and produce a calculation you can attach to your demand letter.
The math in this phase is the most important work in the entire dispute. Everything downstream — the letter, the negotiation, any mediation or arbitration — proceeds from the quality of your calculation.
2. Phase 2: Demand Letter and Initial Response (30–60 Days)
Once you have your calculation, you write and send the demand letter. The clock starts when the letter is delivered.
Typical landlord response timeline:
- Responsive landlords with cooperative property managers: 2–3 weeks
- Average property management offices: 30 days
- Landlords with legal involvement from the start: 30–45 days
- Non-responsive landlords: No response by stated deadline (30–60 days)
If the landlord responds with a substantive engagement — agreeing to some items, disputing others, or requesting a meeting — you are moving into Phase 3 (negotiation) within 60 days of the original letter.
If there is no response, follow up in writing and set a new deadline triggering your next step (formal audit request or dispute resolution filing).
3. Phase 3: Negotiation (30–90 Days)
Direct negotiation between tenant and landlord — usually by correspondence or meeting — resolves the largest share of CAM disputes that reach this phase. The dynamics are straightforward: the landlord prefers a quick credit over a formal audit process; the tenant prefers money now over years of dispute process.
Typical outcomes at this stage:
- Landlord agrees to a credit equal to part or all of the claimed overcharge
- Parties agree on a different calculation methodology going forward
- Landlord agrees to allow audit access in exchange for settlement
If negotiation produces an agreement, document it in a written settlement agreement that specifies the amount, the period covered, and any agreed methodology changes. Verbal agreements made here must be confirmed in writing before you close the dispute.
The most productive negotiations happen when both sides have clear documentation. Tenants who enter negotiation with a well-calculated demand letter and a willingness to explain their math tend to settle faster and for more.
4. Phase 4: Formal Audit (60–120 Days)
If negotiation stalls or the landlord disputes your calculation without providing a substantive basis, a formal audit under the lease's audit rights clause is the next step.
Once you formally invoke audit rights (written notice citing the lease provision), the landlord is typically required to make records available within a specified window — often 30 to 60 days from the request. The audit itself — whether conducted by your CPA or a specialized lease auditor — typically takes 30 to 60 days to complete depending on record quality and complexity.
What the audit produces:
- A formal audit report documenting overcharges with specific accounting references
- A professional calculation that carries more weight in subsequent negotiation or proceedings
- A paper trail showing the landlord's accounting methodology
Audit findings rarely match the tenant's original estimate exactly — they are typically higher (auditors find items tenants missed) or lower (some disputed items turn out to be defensible under the lease language). The audit report becomes the new basis for negotiation or dispute resolution.
5. Phase 5: Mediation (60–150 Days)
If your lease requires mediation before other escalation, or if negotiation has stalled and you want a structured process, mediation is the next step.
AAA data from 2024 shows that commercial mediations resolve within a median of 114 days from filing. About half to two-thirds of commercial disputes that reach mediation settle before or at the hearing.
What mediation looks like:
- Both parties submit position statements to a neutral mediator
- The mediator facilitates joint sessions and private caucuses
- Most resolutions come through mediator-facilitated offers and counteroffers, not joint agreement in the room
- The mediator has no authority to impose a result — either party can walk away
If mediation succeeds, the settlement is documented in a written agreement that becomes binding. If it fails, the next step is arbitration or litigation depending on your lease.
6. Phase 6: Arbitration (2–19 Months)
Binding arbitration is increasingly standard in commercial leases. AAA's 2024 statistics show median time to award in B2B arbitrations ranging from roughly 2 to 19 months depending on claim size. Smaller claims (under $100,000) tend to resolve faster; larger multi-party disputes with discovery can approach 18+ months.
Arbitration is typically less expensive than litigation but has its own costs: arbitrator fees, filing fees, and potentially discovery. Most arbitration clauses specify which rules govern (AAA Commercial, JAMS, etc.) and how arbitrators are selected.
The arbitration award is final and binding — there are very limited grounds to appeal, unlike court judgments. This cuts both ways: a tenant with a well-documented claim has strong odds; a tenant who enters arbitration unprepared has little recourse.
7. Phase 7: Litigation (1–3+ Years)
Full litigation is the final option when arbitration is not required by the lease, when the claim involves issues a court must decide (like statutory remedies), or when the parties have exhausted all other options.
Median time to jury trial in U.S. District Court is approximately 32 months. State court timelines vary but are generally slower than arbitration for commercial disputes.
Litigation costs are substantial: attorney fees alone in a commercial breach-of-contract case typically run $50,000–$200,000+ depending on complexity and whether the case settles before trial. Most CAM disputes settle during litigation discovery when both sides have seen each other's documents.
8. How Most Disputes Actually End
Here is the practical pattern across a broad sample of commercial disputes (not CAM-specific, but the mechanisms are the same): most settle. AAA research indicates that about 46% of B2B arbitrations settle before an award, and one study of 3,750 international arbitrations found only 35% reached a final award. The implication is that roughly two-thirds of disputes that file for arbitration settle before a decision.
For CAM disputes specifically, most resolution happens well before arbitration: in direct negotiation or through the formal audit process. The disputes that go to arbitration or litigation tend to involve large amounts (typically six figures), significant landlord intransigence, or complex lease interpretation issues.
Practical timeline for a typical CAM dispute:
- Well-documented demand letter + cooperative landlord: 6–12 weeks
- Negotiation after initial dispute: 3–6 months
- Formal audit followed by negotiation: 4–8 months
- Mediation: 6–12 months
- Arbitration or litigation: 1–3+ years
The faster path is always available for tenants who have done the math correctly at the start.
Frequently Asked Questions
Q: What's the single biggest factor in how long a dispute takes? A: Whether your demand letter has specific, documented calculations. A vague letter produces a vague response, which produces a long negotiation. A letter with line-item calculations that trace to specific lease provisions tends to either produce a quick settlement or a quick, specific denial that tells you exactly what to prepare for in mediation.
Q: Do I need to wait until the reconciliation period is fully closed to start? A: No. If you receive a reconciliation statement and see what appears to be an error, you can begin calculating and documenting immediately. Most dispute windows start from the date you receive the statement, not from some later date.
Q: What if I have multiple years to dispute? A: Dispute each year separately in the same letter (or in a clear table that breaks out the amounts by year). The dispute window for each year typically runs from when you received that year's reconciliation statement, so different years may have different deadlines.
Q: Can I pursue a CAM dispute while my lease is up for renewal? A: Yes. Many tenants are reluctant to dispute during renewal negotiations, worried the landlord will punish them. This concern is real but often overstated. A well-documented demand letter is a business communication, not an adversarial act. Landlords who lose tenants over legitimate CAM disputes do so because of the dispute's merit, not the timing.
Q: Is the timeline different for a retail tenant versus an office tenant? A: The legal mechanics are the same — the lease governs the process. Retail leases and office leases structure their CAM provisions somewhat differently (retail often uses "gross sales" or "anchor exclusion" provisions), but the dispute timeline follows the same phases.
