Construction Additions: A Complete Guide

Expanding a home or business through a construction addition is an excellent way to enhance quality of life, adapt the property to evolving needs, and even increase its market value. However, behind every addition, whether it’s enclosing a balcony, adding a new room, extending a kitchen, building a Residential Protected Space (RPS), designing a pergola, installing a pool or jacuzzi, or any other type of structural extension—lies a complex professional process. This process requires obtaining a building permit and meeting strict engineering and safety standards. Involving a structural engineer (constructor) from the very beginning ensures practical, professional, and safe engineering planning, while fully complying with all the necessary regulations for successful project execution. Here is everything you need to know:

What Is a Construction Addition?

A construction addition refers to any expansion or modification of an existing building area, whether external or internal, that requires a change to the original building plan. This may include, among others:

  • Adding a room or an additional floor.
  • Expanding an existing space (such as a living room or kitchen).
  • Enclosing a balcony.
  • Building a pergola or utility room.
  • Adding a Residential Protected Space (RPS).
  • Constructing on the roof or adapting it for other uses.
  • Building an in-ground swimming pool, jacuzzi, or any outdoor element requiring structural planning.

In every case where the structure undergoes a physical change, it is essential to ensure compliance with the Planning and Building Law, valid zoning plans, and all relevant engineering standards.

When Is a Property Owner Required to Obtain a Permit for a Construction Addition?

According to Israeli law, a permit for a construction addition is required in any case involving a significant structural change. A permit application will typically be reviewed in the following situations:

  • Unused building rights: If not all allowable building rights were utilized in the original construction, it is possible to apply for their use at a later stage.
  • Zoning plan updates: When a city plan (TABA) has been amended, granting additional building rights.
  • Addition of service areas: Such as a storage room, basement, parking space, pergola, in-ground swimming pool, jacuzzi, laundry room, or technical room.
  • Residential Protected Space (RPS) addition: In accordance with regulations allowing the addition of a protected space, even if it was not included in the original building rights.

The Permit Process for a Construction Addition

Obtaining a permit for a construction addition involves several key stages:

  • Assessment of the existing condition: Reviewing current plans, previous permits, and the legal options available for construction.
  • Architectural and structural planning: Preparing a detailed plan by an architect and a structural engineer.
  • Compliance checks: Evaluating the building’s stability, required reinforcements, and adjustments to meet updated standards.
  • Submitting the application to the local authority: Typically through the “Reshut Online” (online licensing) system.
  • Obtaining supplementary approvals: From the Fire Department, the Home Front Command (in the case of a RPS), and other relevant authorities.
  • Receiving the permit and starting construction: Work may begin only after obtaining an official permit from the municipality or local authority.

The Role of the Structural Engineer in Construction Additions

A structural engineer is the professional responsible for the static design of the building and ensuring its safety. In construction additions, their role includes, among others:

  • Assessing the stability of the existing structure and determining the need for reinforcements
  • Designing the structural framework of the addition to integrate safely with the existing building
  • Providing professional guidance throughout all stages of execution
  • Ensuring compliance with regulatory standards, including earthquake resistance and fire safety requirements
  • Structural engineering services are particularly crucial in cases of heavy construction additions that may affect the building’s stability and strength, such as:
    • Adding a floor or room on an existing roof
    • Building a RPS that must withstand high-pressure loads
    • Constructing an in-ground swimming pool, jacuzzi, or other heavy outdoor elements
    • Expanding older buildings that require reinforcement of the structural framework

Construction Addition: Residential Protected Space

The security situation in Israel has led many citizens to add Residential Protected Spaces (Mamad) to buildings lacking proper protection. Constructing a standard-compliant Residential Protected Spaces requires careful load planning and the preparation of detailed engineering plans in accordance with Israeli standards and the guidelines of the Home Front Command.

RPSs can be added to private home yards, apartment buildings, and/or by reinforcing an existing room within the house.

Exemption from Building Permits for RPSs - Following the “Iron Swords” War

Please note: Following the “Iron Swords” war, the Home Front Command introduced temporary relief measures allowing a fast-track process for building RPSs.

The key update is an exemption from obtaining a local authority building permit when adding a Mamad to structures of no more than two floors, or to housing units without another unit directly above or below them.

RPSs can also be added to buildings with more than two floors; however, in such cases, a full permit is still required.
