Many conflicts in condominiums arise from questions regarding boundaries, common areas, or rules for using the spaces. Horizontal property law establishes a specific legal framework that is not always fully understood by residents, property managers, or owners. Understanding how this system works and how condominium regulations can be adjusted is essential to avoiding disputes, fostering harmonious coexistence, and making informed decisions regarding building management.
What is condominium ownership and how does it work?
Condominium ownership consists of the legal and functional division of a building into separate units, intended for exclusive use, and common areas belonging to all co-owners. Each unit constitutes an independent entity subject to exclusive ownership, and is assigned a percentage that determines the respective owner’s share in the common areas.
Condominium ownership is governed by the provisions of Articles 1414 and following of the Portuguese Civil Code and must be set forth in a deed of incorporation. This document identifies the individual units, the common areas, their respective shares, and the fundamental rules governing the use and management of the condominium.
What rights and responsibilities are outlined in the condominium regulations?
The condominium bylaws are an essential tool for internal organization. They must clearly define the rights and responsibilities associated with the use of common areas, promoting fairness among residents and harmonious coexistence within the building.
Co-ownership is one of the fundamental principles of a condominium, since all unit owners are co-owners of the common areas in proportion to their ownership share. The balanced use of these spaces depends on clear rules that are tailored to the building’s specific circumstances and understood by all users.
How to distinguish between private areas and common areas
In condominium ownership, the proper identification of private areas and common areas is crucial for defining residents’ rights of use, maintenance responsibilities, and limits on their actions. This distinction is often one of the main reasons for amending the condominium bylaws.
Elevators, garages, storage rooms, patios, gardens, and recreational areas are frequent sources of conflict. Clarifying the rules of use in the building regulations contributes to more effective management and helps prevent disputes. In certain cases, the regulations may also clarify criteria for the allocation of expenses, provided they comply with the condominium bylaws and the applicable legal framework.
The condominium rules may change the limits
An amendment to the condominium regulations cannot, on its own, alter the boundaries of units, the ownership percentages, or the classification of common areas. These matters are always governed by the deed of establishment of the condominium and the corresponding land registry record.
However, the technical demarcation of boundaries may serve as a basis for revising the regulations, although any legal modification of the boundaries requires an amendment to the deed of incorporation. A clear demarcation helps clarify situations involving walls, gardens, access points, balconies, terraces, and other areas that may be used either jointly or exclusively.
Walkways, common access areas, and easements in the condominium
Common walkways and access points play an essential role in mobility, safety, and accessibility within the condominium, especially in buildings with outdoor spaces or green areas. Properly defining their location, width, and intended use is essential to ensuring functional and safe access, as well as to clarifying maintenance responsibilities.
In the context of condominium ownership, certain situations are often referred to as easements, although legally they may correspond to rights of use or restrictions set forth in the articles of incorporation or the bylaws. Easements proper, when legally established, constitute real rights that restrict the use of a unit or common area for the benefit of another.
Step-by-step guide to amending the condominium rules
Amending the condominium regulations requires a structured procedure that complies with current legislation. Any unit owner may propose amendments, provided they do so in writing and with supporting justification. In some cases, the condominium manager may also suggest changes, without prejudice to the exclusive authority of the unit owners’ meeting to approve them.
The proposal must be included on the agenda of the next meeting so that it can be reviewed and discussed. Approval confers internal validity on the amendments, provided they comply with the condominium regulations and do not conflict with the articles of incorporation or the law.
Condominium rules are mandatory in all buildings
Whether condominium bylaws are mandatory depends on the building’s configuration. In buildings with more than four separate units, bylaws are required by law. In other cases, while they are not mandatory, their adoption is strongly recommended, especially when there are complex common areas or recurring conflicts.
Even when not legally required, the bylaws serve as an essential tool for clarifying rules, legitimizing the manager’s actions, and minimizing subjective interpretations in the management of the condominium.
What provisions should be included in the condominium bylaws?
Effective building regulations must be clear, balanced, and tailored to the specific circumstances of the building. As a general rule, they should cover the identification of common areas, rules for the use of spaces and facilities, regulations regarding construction work, criteria for the allocation of expenses, rules for coexistence, and procedures to be followed in the event of noncompliance.
These provisions do not supersede the law or the articles of incorporation, but they contribute to a more uniform application of the rules in the day-to-day management of the condominium.
The condominium rules may provide for penalties
The regulations may provide for consequences for non-compliance with the rules, provided that they comply with the law and are approved by the general meeting. Penalties must be proportionate, clearly defined, and applied in a transparent manner, always prioritizing prevention and the balanced resolution of conflicts.
The regulation also applies to tenants and occupants
The condominium rules apply to all occupants of the units, including tenants and temporary occupants. It is the owner’s responsibility to ensure that occupants are familiar with and comply with the current rules.
Amending the regulation requires unanimity
No. Amending the condominium regulations does not require unanimity, except in exceptional circumstances. As a general rule, amendments are approved by the legally required majorities. Unanimity is required only when the amendment affects property rights, such as unit boundaries, ownership shares, or the classification of common areas.
It is possible to divide fractions or find the common parts
The separation of elements such as an apartment, a basement, and a parking space; the division of an independent unit; or the incorporation of a common area into a private unit are only possible by amending the condominium deed, in compliance with all legal requirements and subject to registration with the land registry.
A simple amendment to the condominium bylaws does not have these legal effects.
What is the difference between condominium bylaws and the articles of incorporation?
The deed of incorporation defines the legal structure of the building, identifying individual units, common areas, ownership shares, and real property rights. It is a document subject to registration with the land registry.
The condominium bylaws are an internal and organizational document intended to govern the use of common areas and the coexistence of unit owners; they may not alter the essential provisions set forth in the articles of incorporation.
When specialized technical analysis is required
Whenever there are questions regarding private areas, common areas, boundaries, access points, or easements, a specialized technical analysis can clarify complex situations and provide the basis for informed decisions. The unit floor plan and the topographic survey are essential tools for accurately representing the physical reality of the building.
The importance of specialized technical support
Amendments to the condominium regulations should be viewed as a tool for management and conflict prevention. Whenever boundaries, common areas, easements, or access points are involved, the coordination between the legal framework and specialized technical support is crucial to ensuring legal certainty and stability within the condominium.
