Why penthouse running costs are not proportional

The monthly figure surprises more penthouse buyers than the purchase price does, because it is calculated on a basis most buyers have not thought about.

This page explains how the figure is built. What it is for a specific residence is in the building documents, and the desk will get them. Contact the desk at Miami Dossier for the current position on any building we cover.

How The Figure Is Built

By share, not by use.

Condominium assessments are allocated according to each unit’s share as set out in the declaration, typically related to floor area. They are not allocated by how much a resident uses anything.

A penthouse with a large share therefore carries a correspondingly large portion of the cost of the pool deck, the gym, the valet, the lobby staff, the elevators and the landscaping.

You may never use the gym. You will fund a substantial share of it every month for as long as you own.

The Costs That Are Genuinely Yours Alone

Where the disproportion widens.

Outdoor space. Terraces and rooftops need cleaning, sealing, drainage maintenance and periodic remediation. Salt air and sun are hard on everything exposed to them, and a rooftop with several thousand square feet is a real maintenance programme.

A private pool. Water treatment, equipment, servicing, and the structure supporting it. Pools on roofs also carry a waterproofing system that has a service life and a replacement cost.

Glass. More of it, higher up, harder to reach. Exterior cleaning at height is a specialised operation.

Climate load. A residence with double height volume and extensive glazing on the sunniest exposure costs more to cool, and in a west facing residence considerably more.

Assessments Land Differently At The Top

Share cuts both ways.

A special assessment is allocated on the same share basis. A large share means a large portion of any assessment, including for work that principally serves other parts of the building.

Florida structural inspection and reserve funding requirements have made assessments more predictable and, in many buildings, larger. Older buildings in particular are working through this.

In a small building the arithmetic is sharper still, because there are fewer households to spread any cost across. A twenty five residence building and a three hundred residence building absorb the same repair very differently.

What To Ask For

Three documents.

The current operating budget, with the schedule showing this unit’s share and the monthly figure it produces.

The reserve study, and whether reserves are fully funded. An underfunded reserve is a future assessment with the date left blank.

The assessment history for the past several years, in a building old enough to have one. It is the most honest document about a building you will read.

The Shift

Get the operating budget before the floor plan.

The monthly figure is a permanent obligation and it is knowable before you commit, unlike almost everything else about a preconstruction purchase. Contact the desk at Miami Dossier and we will get the budget, the reserve position and the assessment history for any building you are weighing.

Current availability at the top of any building we cover. What is genuinely open, and what is being held back.
The rooftop instrument. Whether private outdoor space is deeded, a limited common element, or licensed.
Floor plan analysis. What the drawing gives you once column placement, ceiling drops and usable outdoor area are read properly.
Where we would not proceed. Sometimes the answer is another building. Sometimes it is not now.

Common Questions

What buyers ask about penthouse running costs

Why are penthouse maintenance fees so high?
Because assessments are allocated by each unit’s share as set out in the declaration, usually related to floor area, rather than by use. A large residence carries a large share of every shared cost regardless of whether the owner uses any of it.
Do I pay more for amenities I never use?
Yes, and proportionally more than a smaller unit does. Share based allocation is standard and it is not negotiable after purchase.
What does a private rooftop cost to maintain?
Cleaning, sealing, drainage maintenance and periodic remediation, plus pool equipment and servicing if there is a pool, plus the waterproofing system beneath it which has a service life and a replacement cost. Ask how the responsibility is allocated in the declaration.
How do special assessments affect a penthouse?
They are allocated on the same share basis, so a large share means a large portion of any assessment, including for work that mainly serves other parts of the building. In a small building the effect is sharper because fewer households share the cost.
What should I ask for before committing?
The current operating budget with this unit’s share, the reserve study and whether reserves are fully funded, and the assessment history. An underfunded reserve is a future assessment with the date left blank.
Before You Act On Any Of This

You will fund the gym whether you use it or not.

Where a question is legal, tax or structuring, we introduce you to advisers who handle that properly rather than answering it ourselves.
