When a building administrator brings a smart-intercom quote to the owners' assembly, the question that decides the vote is never "how much is the hardware?" but "how much does each apartment pay, and what do we stop paying in exchange?". This is that math, with dated figures: the one-time outlay, the monthly per unit, what the building already spends on the old intercom, and how it all fits into the expensas.

## How much does it cost to put a smart intercom in a building?

For a retrofit like DoorLink, the math has exactly two numbers: a one-time installation of USD 500 to 900 for the building — hardware and labor included, USD 900 is the ceiling — and a service of about USD 8 per apartment per month, with a USD 3 floor in lower-income areas, billed to the building. At the official exchange rate of July 20, 2026 that was ARS 788,000–1,418,000 for the install and about ARS 13,000 per apartment per month; the site shows the day's conversion, because with Argentine inflation any fixed peso figure ages fast.

Where your building lands inside the installation range depends on complexity and unit count: a big building points to the top of the range, but it also divides the cost across more apartments. You can work out the exact total for your case in the [calculator](https://doorlink.com.ar/en/calculator).

Watch out when comparing against other quotes: many market prices are "hardware only", without installation. The full market snapshot — QR, retrofit and complete systems, with dated prices — is in [smart intercoms in Argentina](https://doorlink.com.ar/en/blog/porteros-inteligentes-argentina); here we focus on the building's own math.

## How much does each apartment pay?

Splitting evenly, just to get a sense of scale (the real split goes by each unit's percentage, as we'll see below):

| Building | One-time install per apartment | Monthly service per apartment |
|---|---|---|
| 10 apartments | USD 50–90 | USD 8 (~ARS 13,000 as of 7/20/2026) |
| 20 apartments | USD 25–45 | USD 8 |
| 30 apartments | USD 17–30 | USD 8 |

The important reading: the installation — the scary line in the quote — split across the units comes down to a one-time payment of tens of dollars per apartment. The number the assembly should actually debate is the monthly one, because that's what stays in the expensas forever. Which is why it's worth comparing it against what the intercom already costs today.

## What is the building paying today for the old intercom?

An aging intercom isn't free: it's paid for in repairs, and sometimes in a maintenance subscription that's already in the expensas. Dated references:

![The cost of a DoorLink retrofit split per apartment: in a 10-unit building the one-off install works out at USD 50 to 90 per apartment, in a 20-unit building USD 25 to 45, and in a 30-unit building USD 17 to 30. On top of that comes the monthly service of USD 8 per apartment, with a USD 3 floor, billed to the building.](https://doorlink.com.ar/blog/costo-por-departamento-en.svg)

- **Each technician visit** runs around ARS 36,800 to 56,800 in labor alone (Genz Clima 2026 guide); Home Solution's indicative list, checked July 20, 2026, goes from ARS 38,328 to 165,932 depending on the job, materials not included. Emergency or after-hours calls add a 20% to 50% surcharge.
- **A monthly intercom-maintenance subscription** is a standard expensas line item: CAEPE (the Argentine chamber of intercom companies) publishes reference values from surveys of professionals, with surcharges of 10% to 25% for each additional street panel or unit. If your building pays one, that number is already on every month's statement.
- **Chronic failures repeat.** In old installations, the in-apartment handsets and the degraded apartment wiring are the parts that fail most, producing those intermittent faults that come back every few months. The breakdown by failure type is in [my intercom isn't working](https://doorlink.com.ar/en/blog/portero-electrico-no-funciona).

To compare properly, the administrator has to build the current intercom's annual number: last year's repairs + subscription (if any) + emergency surcharges. That's the new quote's real rival — not zero.

## Does the investment pay itself back? The honest math

It depends on the building, and saying so up front is what makes the rest of the math credible.

**If the intercom fails often**, the comparison favors the retrofit: the one-time install equals between 14 and 38 technician visits in labor alone (ARS 788,000–1,418,000 versus ARS 36,800–56,800 per visit, July 2026 figures), and a building with chronic failures burns through several visits a year, with surcharges when it's urgent. On top of that, the retrofit takes exactly the most failure-prone parts out of the critical path: the call moves to residents' phones, so a broken in-apartment handset stops being an urgent complaint. Unpredictable repair spending turns into a fixed, budgetable monthly.

**If the intercom works fine and barely generates costs**, the math is different and it's worth saying plainly: the monthly fee is a new cost, and what the building buys isn't savings but a service the old intercom doesn't provide — answering from your phone wherever you are, opening the door remotely, and no longer depending on being next to the handset. There are buildings where that justifies the spend and buildings where it doesn't; that's an assembly decision, not a brochure's.

Between those two extremes there's a practical tipping point: if the building already calls the technician several times a year and pays a subscription on top, it's paying in unpredictable installments for something that never gets better. The full discussion between repairing, retrofitting or replacing the whole system is in [replace or modernize the intercom](https://doorlink.com.ar/en/blog/reemplazar-o-modernizar-portero).

## Installation as a special assessment, service as a running cost?

That's the natural way to frame it. The installation is an improvement to common property decided by the assembly — the textbook case of an expensa extraordinaria (special assessment); the monthly service, on the other hand, is just another running cost on the statement, like the elevator contract. Argentina's Civil and Commercial Code obliges every owner to pay both the ordinary expensas for administration and repair of common property and the extraordinary ones passed by assembly resolution (art. 2048), and both are prorated by the percentage the bylaws assign to each unit — not split evenly, unless the bylaws say otherwise.

The context doesn't help anyone hide numbers: expensas in Buenos Aires City rose 75% during 2025 against 31.5% inflation (Octavo Piso's survey of consorcios, January 2026), driven precisely by contracted maintenance services. In that climate, an assembly warms much more to a fixed, transparent monthly than to a story of unpredictable repairs. What majority you need to approve it and how to bring the proposal to the assembly has its own guide: [a smart intercom for the building](https://doorlink.com.ar/en/blog/portero-inteligente-para-consorcio).

## What should you do with this math?

Bring it to the assembly complete. On one sheet: (1) the one-time installation cost and what it comes to per apartment; (2) the monthly per unit, in dollars and at the day's exchange rate; (3) what the building spent on the intercom over the last twelve months, with the repair invoices and the subscription if there is one. With those three numbers on the table, the vote becomes a concrete comparison instead of a debate of impressions.

The honest fit, once more: the retrofit's math works better the more the building spends today keeping a failing intercom alive, and worse if the current system runs perfectly and nobody misses answering from their phone. Work out your building's real annual number before the assembly — and if you want the exact total for your unit count, it's in the [calculator](https://doorlink.com.ar/en/calculator).
