What is a PUP and When Do You Need One?

You hear “PUP” in property and construction conversations, but what does it mean and when do you need one? Here — a complete but accessible explanation.

What PUP is

PUP — Detailed Development Plan — is an urban planning document that determines:

• The purpose of a territory (residential, industrial, public, agricultural, transport);
• Regulation boundaries of properties;
• Construction parameters — footprint, height, density, intensity coefficient;
• Access to infrastructure — streets, water, electric, gas.

PUP is the technical basis for any construction. Without active PUP no design permit can be issued, no project, no construction permit.

Types of PUP

PUP-PRZ — Plan for Regulation and Construction

The most complete. Determines simultaneously regulation and construction. Used for new property regulation or substantial amendment.

PUP-PZ — only Construction

When property is already regulated but construction parameters need change.

PUP-PR — only Regulation

For regulation changes — UPI merging, dividing, street regulation amendment.

PUP-PP — Parcel Plan

For linear objects outside regulation — water mains, electric cables, roads, gas pipelines.

When you need a PUP

Case 1: Agricultural land for construction

Cannot be built on directly. First — PUP-PZ (or PRZ) for purpose change to UPI.

Case 2: UPI but more than allowed by current PUP

e.g. current PUP allows 10m high house, you want a 5-floor residential. PUP-PZ for amendment needed.

Case 3: Merging two adjacent properties

PUP-PR for merging UPIs.

Case 4: Splitting a large UPI

PUP-PR for division.

Case 5: Building infrastructure across multiple properties

PUP-PP — parcel plan.

Procedure step by step

1. Brief — owner defines goal;
2. Design permit application for PUP — to municipality;
3. Source data — sketch, active PUP, OUP, infrastructure;
4. Geodetic survey — accurate boundaries, terrain, infrastructure;
5. Project preparation — graphic and text by registered designer;
6. Coordination — utility operators, environmental agencies, etc.;
7. Public hearing — for projects affecting third parties;
8. ESUT — technical approval;
9. Order from Chief Architect — final approval (after 14-day non-appeal period).

Time and cost

Timelines

• Design permit for PUP: 1 month;
• Project preparation: 1–2 months;
• Coordinations: 2–4 months (most uncertain stage);
• Public hearing + ESUT + Order: 1–2 months.

Total: 4–9 months for standard PUP.

Costs

• Small PUP-PZ for UPI in Sofia: from 1500 BGN;
• Average PUP-PRZ: 2500–5000 BGN;
• Large PUP for industrial or solar park: 5000–15,000 BGN;
• State fees, coordination fees, announcements: separate, 300 to 2000 BGN.

Common mistakes

• Starting PUP without design permit — invalid from start;
• Ignoring OUP — General Development Plan sets the framework;
• Underestimating coordination timelines;
• Public hearing without preparation — neighbors can appeal and delay months.

Difference between PUP and design permit

• PUP is an urban planning plan that creates or changes regulation. Valid for decades.
• Design permit is an extract from the active PUP, needed to prepare investment project for a specific building. Valid 6 months.

Without active PUP no design permit can be issued; without design permit no construction project.

Conclusion

PUP is a complex document, but with proper approach and good coordination — feasible in reasonable time.
