What Are Building Rights and Why Do They Matter in Every Real Estate Transaction
Building rights are the planning framework that defines what can be built on a given plot. They are established by the local zoning plan (Taba) and specify the total buildable area (as a percentage of the plot), number of floors, maximum height, and building lines.
Israeli courts have ruled that building rights are not property rights themselves. They are derived from planning law — meaning they represent the right to apply for a building permit under the conditions set by applicable plans. Building rights can change when a new zoning plan is approved.
There are two main types: rights under the Taba (baseline rights in a valid plan) and relief permits (Hakalot) — additional rights granted at the local planning committee's discretion.
| Term | Meaning | Example |
|---|---|---|
| Building percentage | Ratio of allowed construction to plot area | 500sqm plot x 60% = 300sqm |
| Primary area | Space for main purpose (residential, commercial) | Living room, bedrooms, kitchen |
| Service area | Space serving the primary area | Safe room, storage, parking |
| Building lines | Minimum distance from plot boundaries | 3 meters from side boundary |
| Relief permit | Approval to build beyond Taba | Additional 6% area |
- Building rights are a core component of your property's value — not a marginal addition
- The distinction between primary and service area directly affects how much you can build
- In older zoning plans (pre-2000), building percentages are lower — in older neighborhoods the gap between built and allowed can be significant
How to Check Building Rights — Step by Step
Checking building rights is one of the most important steps before any real estate transaction, especially for private homes.
Step one: find the plot's Gush and Helka numbers (block and parcel) — from the Tabu extract, purchase contract, or Israel Land Authority website.
Step two: visit the Planning Administration website — Mavat LaTochnit (mavat.iplan.gov.il). Search by Gush and Helka to see all applicable plans and their status.
Step three: contact the local planning committee. In Kiryat Ono, the local committee operates independently and issues a detailed planning information sheet covering all valid building rights.
Beyond self-research, consulting an architect or real estate appraiser for an in-depth assessment is highly recommended.
- The planning information sheet from the local committee is the most accurate document
- Mavat is a free tool for initial screening but doesn't replace thorough review
- In Kiryat Ono, contact the municipality's Planning and Engineering Department directly
Building Rights for Private Homes — Why It Matters Before Every Transaction
For private homes, building rights are often a significant component of property value that homeowners aren't always aware of. In Bikat Ono this is especially relevant.
Example: a 100sqm home on a 300sqm plot in old Kiryat Ono. If the Taba allows 120% building, you could build up to 360sqm — 260sqm of unused rights. Of course, realizing these rights involves costs (planning, permits, construction, betterment levy), so actual value is lower than the theoretical figure.
In Ganei Tikva, many homes sit on 300–520sqm plots with only 200–260sqm built. In some cases 40–60% of building rights remain unused.
| Rights type | What it includes | Value impact |
|---|---|---|
| Primary building rights | Rooms, kitchen, living room | High |
| Service area rights | Storage, basement, parking | Medium |
| Safe room (up to 12sqm) | Protected space | High — often exempt from percentage |
| Attic space | Area above 1.80m height | Medium-high |
- In older neighborhoods the gap between built and allowed may reach hundreds of square meters
- A safe room up to 12sqm may be exempt from building percentages
- Unused rights value depends on the difference between current and potential value, minus realization costs
Building Rights in Apartment Buildings — What Most Buyers Don't Know
Building rights also affect apartment values — just in a more complex way.
In shared buildings, unused building rights belong to all apartment owners as common property.
In Kiryat Ono's Kiraon neighborhood, a significant portion of buildings have undergone urban renewal processes. The city's master plan aims to grow to approximately 80,000 residents by 2040, with about 5,500 new apartments.
Under Tama 38/1, residents get up to 25sqm gross expansion per unit including safe room. Under Tama 38/2, residents receive a larger new apartment.
Kiryat Ono is one of nine municipalities that promoted a Tama 38 replacement plan. Tama 38 has expired, and in these municipalities a replacement urban renewal plan is now in effect.
- Unused building rights belong to all residents, not just the top-floor tenant
- Kiryat Ono has a local replacement plan for Tama 38
- In older buildings (pre-1980), unused building rights are worth checking
Risks and Building Violations — What Happens When Things Aren't Up to Code
Building violations are one of the most common problems in Israeli real estate. A violation is any change, addition, or use made without proper authorization.
Legally, a building violation is a criminal offense. Property owners face fines, demolition orders, and criminal charges. Bank appraisers will reduce property value and may refuse mortgage approval.
If buying a home and discovering unpermitted additions — expect mortgage difficulties, legalization costs, or demolition costs.
Sellers face fraud claims for undisclosed violations. Disclosure obligation falls on the seller. Consulting a real estate attorney before purchasing a property with violations is recommended.
| Violation type | Example | Main risk |
|---|---|---|
| Unpermitted addition | Enclosed balcony | Demolition order, mortgage issue |
| Unauthorized use | Storage to dwelling | Cease-use order |
| Building line violation | Too close to boundary | Neighbor disputes |
| Excess percentage | Over-utilizing rights | Retroactive levy |
- Always review the building file at the local committee before purchasing
- Violations hurt value and may prevent mortgage approval
- Enclosing a balcony without a permit is a legal violation
Betterment Levy — The Hidden Cost of Building Rights
When a new plan increases building rights, the municipality may charge a betterment levy — 50% of the value increase.
Payment is triggered upon realization — sale, permit application, or utilization. Calculated from the plan approval date.
Urban renewal projects (Tama 38 and replacements) generally enjoy exemption. Over 2.5 added floors — only 25% levy.
If unused rights are worth NIS 500,000, the levy could reach NIS 250,000. Factor this into your calculation. Consulting a real estate appraiser to estimate the expected levy is recommended.
- Betterment levy is 50% of value increase, not total property value
- Payment triggered only upon realization, not immediately
- Urban renewal projects enjoy exemption or reduced levy
