What is a retroactive building permit in Israel and how do you apply?

A retroactive permit (bakhsharat biniyah bediavad) is an application to the local planning and building committee (Vaad Mekomit leTikhun uViniyah) to formally approve construction that was built without prior permission. The structure must comply with the current local outline plan (tochni mekomit) — the addition must fall within the permitted floor area ratio, respect setback and height limits, and be structurally safe. If it violates current zoning, the application will be refused and a demolition order typically follows.

The application process: engage a licensed architect to prepare as-built drawings and a planning compliance report, submit to the local committee with a fee of approximately NIS 2,000–8,000, await assessment of a development levy (hetel hashbacha) of NIS 5,000–50,000+ on the additional floor area, and wait for the committee's decision. Total legalization cost for a single enclosed balcony in Tel Aviv typically runs NIS 20,000–45,000. The process takes 6–18 months. Once approved, the Land Registry (Tabu) can be updated to reflect the increased floor area.
