Rooftop equipment can be an owner asset, tenant fixture, operator-owned system, common-property installation or legacy condition. A sale-ready record connects each zone and system to property control, agreements, federal and local records where relevant, building evidence, access, revenue, expense, transfer and end-of-term responsibility.
This is general information, not legal, tax, environmental, engineering, accounting or investment advice. Obtain advice specific to the property and transaction.
1. Build the rooftop asset and rights register
Index every roof zone, antenna, mount, cabinet, shelter, cable, fibre, generator, HVAC, exhaust, solar, sign and access route. Record operator or user, ownership, agreement, authority records, current status and source documents.
Do not combine visible equipment, licensed premises, lease income and future roof potential into a single claim.
- Zone and equipment
- Owner or user
- Private right
- Authority record
- Income and expense
- Transfer status
2. Prove control and contract status
Reconcile title, condominium and shared-site documents, rooftop leases and licences, access and utility rights, assignments, amendments, notices, defaults and lender consents with counsel. Identify exclusive zones, expansion, relocation, sharing, termination and restoration.
An installed antenna or collected payment does not by itself prove an enforceable, assignable or current agreement.
3. Reconcile federal and local records
For antenna systems, collect the proponent's CPC-2-0-03 classification, ISED correspondence where applicable, land-use-authority submissions, consultation evidence where required, local correspondence and concurrence record. Match the file to the current equipment and modifications.
Missing records are an unresolved diligence item, not proof of approval or non-compliance. Do not represent an exclusion without the current supporting scope.
4. Assemble roof, structure and permit evidence
Collect roof plans, condition reports, warranty, structural reviews, equipment weights and attachments, building and electrical permits, inspections, leak and repair history, access protocols and dated photographs. Record superseded and removed systems.
A visual inspection or operator letter does not certify the building, structure, membrane or electrical work.
5. Rebuild income and expense
Tie rent, escalations, option periods, additional-user payments, revenue share and reimbursements to executed documents, invoices, deposits, collections and arrears. Reconcile electricity, access, management, professional, repair, insurance, tax and restoration costs.
Disclose contractual, billed and collected amounts separately. Do not publish a value or cap-rate effect without an appropriate valuation process.
6. Control marketing statements
Use sourced, dated language for rooftop income, term, renewal options, operator, equipment, access, roof condition, permits and expansion. State whether information is owner-provided, agreement-based, authority-sourced or subject to buyer verification.
Avoid guaranteed income, passive income, transferable antenna approval, unused roof capacity or expansion ready unless the exact evidence and limitations support the statement.
7. Prepare staged buyer and lender access
Provide summaries first, then agreements, technical records, authority files, financial evidence and controlled access after qualification and confidentiality steps. Protect building access controls, network details, credentials and personal information.
A buyer, lender, insurer, operator or authority may require independent review. Controlled disclosure does not replace it.
8. Resolve transfer and closing work
Schedule assignments, consents, estoppels, notices, prepaid or arrears adjustments, deposits, utility accounts, insurance, contacts, keys and document delivery. Address change-of-control clauses and representations with counsel.
Update the offering, data room and agreement if equipment, lease status, rent, roof condition or authority information changes before closing.
9. Quantify unresolved removal and capital exposure
Identify obsolete or abandoned equipment, upcoming roof replacement, conflicts, structural review gaps, leaks, electrical work, removal deadlines and restoration responsibility. Obtain supportable cost evidence where material.
Commercially coordinates licensed commercial real estate search, marketing and transaction evidence. It does not interpret title, condominium documents, leases or licences; determine federal, municipal, building, electrical or aviation requirements; assess radiofrequency exposure; certify structural or roof capacity; value rooftop rights or telecom income; or provide engineering, planning, tax, insurance, telecommunications or legal advice. Commercially can build a source-controlled campaign and inquiry pathway without turning owner information into a legal, technical, safety, compliance, income or value certification.
