Iranian Urban Planning History
This domain rewards knowing the sequence of Iranian planning instruments and institutions, and the difference between the master plan and the detailed plan in law and in practice.
The sequence
- Pre-modern fabric - organic growth around bazaar, jaame' mosque and arg; the mahalle, koocheh, hoze and caravanserai as the spatial grammar.
- 1907 - first Baladiyeh (municipality) law after the Constitutional Revolution; an early modern municipal mandate.
- Reza Shah era - grid street cutting through the organic fabric (Tehran's Pahlavi/Valiasr axis), municipal ordinance power, first zoning intentions.
- 1960s–70s - comprehensive planning imported: Tehran's master plan prepared by a foreign consultant team and approved around 1969; the Supreme Council of Urban Planning and Architecture (Shora-ye 'Ali-e Shahrsazi va Me'mari) established in 1972 as the approving authority for plans.
- Post-1979 - the 1982 urban land law nationalised urban land and made municipalities major land suppliers; the tarh-e tafzili became the operative instrument, block by block.
- 1990s–2000s - variants: tarh-e rahnamayi for small towns, tarh-e jame' revisions, and newer development-strategy framing.
Worked example
A city of 180,000 has a master plan at 1:25,000 showing broad land uses, and a detailed plan at 1:2,000 showing plot boundaries, setbacks and densities. A question asks which document controls a specific building permit: the detailed plan, because the master plan sets policy while the tafzili fixes legally binding plot-level rules enforced through the Article 100 commission.
Traps
- Reversing the master/detailed hierarchy and their scales.
- Assuming a plan becomes binding when the municipality adopts it - approval authority sits above the municipality.
- Ignoring that the 1982 land law changed the supply logic, not just the plan drawings.
