Commercial Lease Review Agent
The Commercial Lease Review Agent reviews office, retail and industrial leases for either landlord or tenant, covering rental and escalations, operating costs, municipal rates and utility recoveries, repairs, assignment and subletting, renewal, deposit and guarantees. It compares the lease to the agreed heads of agreement and flags every gap, so the signed lease reflects the commercial deal.

Indicative figures. We measure your own baseline in the first fortnight so the numbers you see are yours.
The deal you agreed is the deal you sign
Differences between the heads of agreement and the lease draft are a common source of disputes. The agent lines the two up clause by clause and flags every mismatch.
Recoveries you can understand
Operating cost, rates, utility and backup power recoveries drive the real cost of occupation in South Africa. The agent sets out exactly what is recoverable, how and on what basis.
Faster leasing cycles
Leasing teams and attorneys get a structured review quickly, so lease execution keeps pace with occupation dates and brokers' timelines.
Capabilities
Know exactly what a commercial lease costs and commits you to before signing.
Built for property attorneys, commercial landlords, REITs, asset and property managers, corporate real estate teams and tenants' legal advisers in South Africa.
Heads of agreement comparison
Compares the lease to the signed heads of agreement on rental, escalation, term, tenant installation allowance, beneficial occupation and renewal, and lists every difference.
Rental and escalation analysis
Extracts base rental, annual escalation rates and any turnover rental, and builds a rental schedule across the lease term in Excel.
Operating cost and utility recoveries
Reviews recovery of operating costs, municipal rates, electricity and water via sub-metering, and generator, backup power or solar costs, and flags open-ended recovery clauses.
Repairs, alterations and reinstatement
Sets out the split of maintenance responsibilities, structural versus internal repairs, alteration consents and reinstatement obligations at the end of the lease.
Assignment, renewal and security
Checks assignment and subletting consents, renewal options and notice periods, deposit amounts, bank guarantees and suretyships.
Lease abstract
Produces a one-page lease abstract with key dates, amounts and obligations, ready for loading into your property management system.
How it works
From your systems to a result you sign off
The property attorney or leasing manager reviews the findings and approves the final lease before it is signed.

Deployment
Runs inside the tools your team already uses
The same agent and the same cited output, delivered three ways: through the AI assistant you have rolled out, on a model you host yourself, or inside your own software.
In the frontier assistant you already pay for
We publish the agent as an MCP server. Add it as a connector and your team calls it from the chat they use every day, with no new tool to learn.

How we deliver it
One agent, three ways to hold it
Start where your team already works, then take it as far into your systems as the value justifies.
DATA SECURITY & PRIVACY
Your lease agreements stay yours.
The agent runs inside your tenancy, reads only what each task needs, and never trains on your lease agreements. Every step is logged so your auditors can see exactly what it touched.
Built for regulated work.
