Hiring Building Contractors in Bulgaria 2026 | Complete Guide
Whether you’re building over 100m² (requiring professional construction) or simply want expert help with your self-build project, finding reliable contractors in Bulgaria requires careful vetting. The right contractor can make your project successful; the wrong one can become a nightmare.
This guide helps you find, evaluate, and work effectively with Bulgarian construction professionals.
When You Need a Contractor
Required by Law (Over 100m²)
Bulgarian building law requires licensed construction for homes over 100m²:
- Licensed construction company registration

Optional but Helpful (Under 100m²)
For self-build eligible projects, you might hire contractors for:

- Roof construction (safety and waterproofing critical)
- Electrical installation (licensed electrician required by law)
- Plumbing (complex systems benefit from experience)
- Specialized finishes (tiling, plastering)

Vetting Process
Step 1: Initial Contact (Screen Multiple)
Contact at least 3-5 contractors:

- Request preliminary meeting
- Note responsiveness and professionalism
Step 2: Site Meeting
Meet contractors at your building site:
- See how they assess the project
- Discuss your plans and timeline
- Ask about their approach
- Gauge communication style
Questions to ask:
- How many similar projects have you completed?
- What’s your current workload?
- Who would be the site supervisor?
- How do you handle changes/problems?
- What’s your payment structure?
Step 3: Written Quotation
Request detailed written quotes including:
- Itemized breakdown by construction phase
- Materials included vs. owner-supplied
- Labor costs clearly stated
- Timeline with milestones
- Payment schedule
- What’s excluded
Compare quotes carefully:

- Clear payment terms?
Step 4: Reference Check
For your top 2-3 candidates:
- Request 3+ recent client references
- Actually call/visit references
- Ask specific questions about experience
- Look at completed work if possible
Questions for references:
- Was the project completed on time?
- Were there cost overruns?
- How were problems handled?
- Would you hire them again?
- Any issues after completion?
Step 5: Contract Negotiation
Never start work without a written contract covering:
- Detailed scope of work
- Specifications and materials
- Total price and payment schedule
- Start and completion dates
- Penalty clauses for delays
- Warranty terms
- Dispute resolution process
- Insurance requirements
Contract Essentials
Payment Structure
Standard Bulgarian practice:

Protect yourself:

- Keep retention until all defects resolved
- Get receipts for all payments
Change Management
Projects change. Your contract should specify:
- How changes are requested
- How changes are priced
- Who approves changes
- Documentation requirements
- Impact on timeline
Quality Standards
Specify in contract:

- Note deviations from plans
- Require corrections before proceeding
Problem Resolution

This saves money while ensuring critical elements are professionally executed.
Frequently Asked Questions
How do I verify a contractor is properly licensed?
Check the Bulgarian Chamber of Builders (Камара на строителите) online registry. Verify company registration with the Commercial Register (Търговски регистър). Ask to see licenses and insurance certificates.
Should I pay in cash?
Always request and pay by bank transfer with clear description. Cash payments leave no record for disputes or tax purposes. Legitimate contractors accept bank transfers.
What if my contractor abandons the project?
Document everything, retain any payments owed, consult with lawyer about contract enforcement, and be prepared to find replacement contractor. Prevention (proper vetting, milestone payments) is better than cure.
Can I hire foreign contractors?
EU contractors can legally work in Bulgaria. They should still be registered for Bulgarian tax purposes. Communication and warranty enforcement may be more complex with foreign contractors.
