Shared Rooftop Gardens in Condo Buildings: What to Check

A rooftop garden has become one of the most attractive amenities when buying a condo in a new building, but because it is a shared common area, it comes with rules, costs and responsibilities that go well beyond the pretty photo in the sales listing. Before you let the view or the garden on the roof win you over, review the usage rules, how maintenance expenses are split among the unit owners (condóminos), and what happens if the area gets overcrowded at peak times or on weekends, when every neighbor wants to use it at once.

Usage rules you need to know

Each condominium sets its own rules for the rooftop garden: access hours, whether guests are allowed, whether you need to reserve the space for private events, and what restrictions apply to music, grills or pets. Always ask for the internal rules (reglamento interno) before buying, not just the developer's marketing promises. It is common for these rules to change once the administration passes from the developer to the owners' assembly (asamblea de condóminos), so ask whether a final set of rules already exists or is still pending approval, since the initial rules can be modified once the building is occupied.

Costs and shared responsibility

Upkeep of a rooftop garden (irrigation, pruning, cleaning, furniture repairs) is paid for through the building's general maintenance fee, which can make that fee higher than in buildings without this amenity. Key points to verify before signing any purchase contract:

• Whether there is a specific reserve fund for repairs to the green area
• Who is liable for accidents or damage that occur in the common space
• Whether access is limited by capacity or requires advance reservation
• Whether there are extra charges for private events in the area, such as post-event cleaning fees

Key questions for the developer or seller

Before signing, it is worth asking in writing who will manage the rooftop garden during the first years after the building is delivered, since many developers keep control of the administration for an initial period before handing it over to the owners' assembly. You should also ask whether the irrigation system is automated or depends on maintenance staff, how the structural safety of the roof is handled (waterproofing, rainwater drainage), and whether there is specific insurance for the furniture and plants in the common area, beyond the building's general insurance against fire or structural damage.

Frequently asked questions

Does a rooftop garden increase the building's maintenance fee?

Yes, it usually does, because it involves irrigation, gardening and upkeep of additional furniture. It is a good idea to compare the maintenance fee against similar buildings without this amenity before deciding.

Can I reserve the rooftop garden for a private event?

It depends on each condominium's rules. Some allow advance reservations with an additional fee, while others strictly limit it to individual use with no group events.

What happens if the rooftop garden has leaking problems?

Repairs are normally paid from the condominium's maintenance or reserve fund, unless the damage is proven to result from a resident's misuse, in which case individual liability may be enforced under the internal rules.
