Building Permit Guide — When You Need One and What to Check in a Transaction

What is a Building Permit and Why is it Critical in a Real Estate Transaction

A building permit is an official authorization issued by a local authority (municipal or regional council) that grants the right to construct, expand, change use, or perform substantial construction work on a property. It is a critical legal document in real estate transactions, as it confirms that the construction complies with city planning, building regulations, and all regulatory requirements.

When you purchase a property where construction work or additions have been performed — whether an expansion of a house, addition of a floor, modification of an apartment layout, or reconstruction — the building permit is the document that proves the work was carried out legally and with the consent of the authorities. The absence of a building permit or a defective permit can lead to significant damages: demolition orders, fines, questionable legality, and substantial depreciation of the property's value.

Our firm, Mandelbaum, Gor, Weizman-Gor and Partners, Attorneys at Law, assists buyers and sellers in conducting thorough building permit verification as part of the property purchase process. Based on our experience since 2008, we have seen how careful examination at an early stage prevents civil lawsuits, legal disputes, and unexpected future payments.

When Exactly is a Building Permit Required

Not every property modification requires a building permit. Israeli building regulations distinguish between work that requires a permit and minor work that does not. This distinction is critical, as performing work that requires a permit without obtaining one is illegal, while performing work that does not require a permit without one is not illegal.

• Work Requiring a Building Permit: New construction, expansion of an existing building, addition of a floor, significant change of use (for example, from commercial to residential), structural modifications (load-bearing walls, ceilings), erection of a substantial ancillary structure (storage, garage), excavation or lowering of a floor, installation of an elevator, and the like.
• Work Not Requiring a Building Permit (Minor Work): Painting, vinyl flooring, plumbing repairs, installation of interior doors, repairs to existing roofs, installation of air conditioning within an apartment (under certain conditions), and the like. However, even minor work may require a permit if it affects the building facade, sight lines, or public areas.

The common problem is that property owners, and especially contractors and subcontractors, do not always wait for or even request a permit. They begin work thinking it is "minor work" or hoping they will not be inspected. This is a significant risk.

Essential Building Permit Checks in a Transaction

When you are in the process of purchasing a property or in an agreement for the existence of a property where construction work has been performed, a systematic check of the building permit must be conducted. This is not a check that can be completed in one day — it requires tracking documents, coordination with local authorities, and verification of technical details.

1. Verification of Building Permit Existence in the Local Authority System

The first step is to request confirmation from the local authority (the municipal or regional council) of the existence of a building permit for the property. This is usually done through an official request or through a legal advisor or engineer. The authority will provide information on:

• Building permit number
• Date of permit issuance
• Type of authorized work (construction, expansion, change of use, etc.)
• Permit status (valid, completed, suspended by law, or cancelled)
• Engineer responsible for the project

It is very important to determine whether the permit is still valid or has been completed. A completed permit means that the work has been finished, the authority has issued a completion certificate (or work completion approval), and the property can be used legally.

2. Verification of Completion Certificate and Work Completion Approval

Upon completion of work under a building permit, the contractor or developer must submit a request for a completion certificate. This is an official certificate that confirms that the work has been completed in accordance with the permit and building regulations. If a building permit exists but there is no completion certificate — this is a red flag. It may indicate that the work was not completed properly or was not approved by the authorities.

Also check whether building inspections (phased inspections) were conducted by the authority's engineer. These inspections verify that the work is being performed in accordance with the plan and regulations.

3. Verification of Correspondence Between Actual Work and the Approved Plan

It is very important to check that the work actually performed corresponds to the approved plan in the permit. Sometimes contractors or property owners make changes to the work (for example, a larger expansion than planned, or a change of use that was not approved) without updating the permit. This creates a legal discrepancy.

To do this, obtain the approved plan from the authority and compare it to the actual work on the property. If there are significant differences, immediately determine whether there is an updated permit or authority approval for the changes.

4. Verification of Tax Payment and Building Fees

A building permit often comes with a requirement to pay building fees, betterment tax, or other costs to the local authority. Check whether all payments have been settled. If building fees or taxes have not been paid, the authority may withhold the permit or place a lien on the property.

5. Verification of Building Legality and Compliance with City Plan

Check that the construction complies with Israel's building regulations, the city plan (Taba), and local regulations such as height limitations, building density, building lines, parking requirements, and the like. If the construction does not meet these requirements, the authority may issue a demolition order or require modifications.

6. Verification of Legality Regarding Neighbors and Third-Party Rights

Also check whether the construction infringes on the rights of neighbors or owners of adjacent properties (for example, photographic distortion, shading, breach of a building line affecting a neighbor). If there are unresolved neighbor complaints, they may lead to civil lawsuits or requests to cancel the permit.

Common Risks — What Can Go Wrong in a Real Estate Transaction

Based on our experience as real estate attorneys since 2008, we have repeatedly witnessed cases where property buyers or owners failed to properly verify building permits. Here are the most common risks:

Building Permit That Does Not Exist or Has Expired

This is the most common case. A contractor or property owner constructed or expanded the property without a building permit, or the permit exists but no final completion certificate was requested. As a result, the authority may issue a demolition order, or the property is classified as "illegal construction" and cannot be legally sold or leased.

Building Permit Expired but Work Remains Incomplete

Sometimes a building permit expires before the contractor completes the work or submits a request for a final completion certificate. The property owner is left with partial construction without a valid permit to complete it.

Discrepancy Between Approved Plan and Actual Work

The contractor built more than planned, or changed the use without formal approval. For example, a building permit application for an additional story of 50 square meters, but actually 80 square meters were built. This opens the door to legal claims by the authority or neighbors.

Legality Questioned Due to Unapproved Work

If minor work was performed without a permit (for example, adding a small room or installing air conditioning on the building facade), the authority may require demolition or correction. This affects the property's value and your ability to sell or lease it.

Outstanding Financial Obligations

If building fees or taxes have not been paid, the authority may place a lien on the property or withhold a sale certificate until payment is made.

Unresolved Neighbor Complaints

Neighbors may file a complaint with the authority or a civil lawsuit if the construction infringes on their rights (views, shading, noise). If the complaint is not addressed, it may lead to a legal action or even permit cancellation.

How to Protect Yourself in a Transaction

To protect yourself as a buyer or seller, we recommend the following steps:

1. Commission an Early Legal Review: Even at the offer or conditional agreement stage, ask a legal consultant or engineer to review the building permit. Do not wait until the final signing stage.
2. Obtain Copies of All Documents: Building permit, final completion certificate, inspection approvals, approved plan, and any authority authorization.
3. Verify Independently or Through a Consultant: Do not rely on the owner's or contractor's word. Check directly with the local authority.
4. Adjust the Purchase Price: If there are building permit issues, reduce the purchase price to reflect the risk or cost of correction.
5. Insert Conditions in the Contract: Include language in the purchase agreement obligating the seller to provide a valid building permit, or allowing the buyer to cancel the transaction.
6. Obtain Insurance: For large transactions, consider insurance against construction risks or title insurance (property ownership issues).

Building Permit Application Process — What You Need to Know

If you are a property owner considering construction work, or if you are a contractor planning a project, it is important to understand the building permit application process. This is a formal process that requires time, documentation, and payments.

Steps in the Building Permit Application Process

1. Plan Preparation and Planning: You need to prepare a technical plan of the planned work. The plan must be certified by a licensed engineer or architect. The plan must comply with building regulations, the city plan, and all local requirements.

2. Submission of Application to the Local Authority: You submit the plan and formal application to the local authority. The authority will review the plan and provide comments or request changes.

3. Review and Refinement: If the authority requests changes, you need to update the plan and resubmit it. This process may take several weeks or months.

4. Issuance of Building Permit: After the authority's approval, the building permit is issued. The permit comes with conditions, such as building fees, appreciation tax payment, safety requirements, and the like.

5. Execution of Work: The property owner or contractor begins work in accordance with the permit. The authority typically conducts periodic inspections to ensure the work is being carried out properly.

6. Request for Certificate of Completion: After the work is completed, you submit a request for a certificate of completion. The authority's engineer inspects the work and issues a certificate of completion if everything is in order.

How Long Does a Building Permit Application Take

The processing time for a building permit application varies depending on the complexity of the project and the workload of the authority. Generally:

• Simple application (for example, small addition or minor modification): 4–8 weeks
• Medium application (for example, expansion or medium-sized new construction): 2–4 months
• Complex application (for example, large project, or project in sensitive area): 4–12 months or more

It is important to plan your timeline accordingly. Do not start work before obtaining a permit, even if you think it will take a long time.

Costs Associated with Building Permit

A building permit application involves many costs. These are not actual construction costs, but official and governmental costs:

• Building Fees: Payment to the local authority based on the area of new construction. The rate varies depending on the city and type of construction.
• Appreciation Tax: Tax to the government on the increase in property value due to construction. This is usually a percentage of the added value.
• Planning and Inspection Fees: Fees to the authority for reviewing the plan and inspecting the work.
• Engineering Fees: Payment to the licensed engineer or architect for preparing the plan.
• Construction Insurance: Mandatory insurance on the project.

The total sum of these costs can be significant, especially in large projects. It is important to budget for these costs in advance.
