From Plot to Keys: 18-Month Bulgarian House Building Timeline (2026 Mega-Guide)
Eighteen months is the honest answer for plot-to-keys in Bulgaria. Less is possible only with a ready-made design and a calm municipality.
This guide walks through every month, what we work on, what we wait for, and where the time really goes. Read it before you sign a plot.
Months 1–3: Plot, Survey, PUP Visa
The first three months are mostly paperwork and surveys, not drawing. We start with a notarial deed check, then geodetic survey and soil report.
The PUP visa (виза за проектиране) is the legal trigger to design. Legally it issues in 30–90 days; in practice we plan for 60–120.
In parallel, we run a feasibility study and confirm utility positions. Our building permits guide and documents needed post list what you need ready.
If the plot needs a PUP amendment, add three to six months. We always check this before quoting a project.
Months 4–6: Project Development and Permit Submission
Months four to six are the heart of architectural work. We develop concept, schematic and technical drawings, with three rounds of client review.
By month five, all engineering parts (structure, electrical, plumbing, HVAC, energy, fire) are coordinated under our lead. Each engineer is a KAB (Камара на архитектите в България, Chamber of Architects) or CIAB-registered specialist.
Month six closes with the permit submission to the municipality. The required set is defined under ЗУТ and reviewed by the chief architect.
For ready-made designs like House X-009 or House X-011, this phase compresses to 6–8 weeks total.
Months 7–9: Permit Approval and Construction Start
The Разрешение за строеж (construction permit) has a 30-day legal review window. In practice, we plan for 60–90 days depending on the municipality.
Use this gap productively. We sign the constructor contract, finalise material specs, and order long-lead items (windows, heat pump).
Construction starts when the permit is in hand and the constructor’s site notification is filed. The first month is excavation, foundation and waterproofing.
Our hiring contractors guide explains how to choose a constructor without losing the savings you made on design.
Months 10–15: Shell, Roof and MEP First-Fix
Shell construction for a 100 m² brick house runs 3–4 months. Roof and facade add another 2–3 months, often partly overlapping.
MEP first-fix (electrical, plumbing, HVAC rough-in) takes 1–2 months and runs in parallel with internal walls. This is where our weekly site visits matter most.
By month 14 or 15, the building is weather-tight, the roof finished, and inside fit-out begins. We sign Act 14, confirmation that the structure is complete and matches the permit.
Our Casa Shanti and residential building projects both followed this rhythm closely.
| Phase | Duration | Runs in parallel with |
|---|---|---|
| Shell (100 m² brick) | 3–4 months | Roof start, window order |
| Roof + facade | 2–3 months | MEP first-fix |
| MEP first-fix | 1–2 months | Internal walls |
| Finishing | 3–4 months | Site landscaping |
Months 16–18: Finishing, Act 14/15/16 and Move-In
Finishing trades take 3–4 months: screed, plaster, tiles, flooring, painting, kitchens. This is the noisiest phase and the most decision-heavy for the client.
Then come the three acts. Act 14 (already signed at month 15) confirms structure; Act 15 is the building’s acceptance by DNSK (National Construction Control) and the design team.
Act 16, Удостоверение за въвеждане в експлоатация, is the usage permit. It is what your bank and registry actually want.
Utility connections often add 2–4 months if not started early. Winter (December–February) adds 1–2 months on most sites. See our realistic building timeline post for variations.
FAQ
Is 18 months realistic for building a 100 m² house in Bulgaria?
Yes, if the plot is regulated, the design is straightforward, and you start the permit dialogue early. With a ready-made design we have closed at 14–15 months; with a custom design and a PUP change, 22–26 is realistic. Eighteen is the median, not the floor.
What can run in parallel to save months?
Quite a lot. Material orders, constructor selection and utility applications all overlap the permit-review wait. Roof and MEP first-fix overlap the shell finish. Treat the Gantt as layered, not sequential.
Why do permits take longer than the legal 30 days?
Because the 30 days only count once the file is complete. Any missing document resets the clock, often quietly. Municipalities also pause for legal holidays, sick leave and inter-departmental review.
What is Act 14 and when does it happen?
Act 14 confirms that the load-bearing structure is built according to the permitted design. It is signed by the constructor, structural engineer, author supervisor (architect) and DNSK. It usually happens around month 15, once roof and slabs are done.
Can I move in before Act 16?
Legally no, the house is not in usage until Act 16 is issued. Practically, many owners do, but it voids insurance and complicates utility contracts. We always advise waiting the extra few weeks.
