Project Manager for Flat Conversion: Purpose and Role
Published 25 October 2026
A project manager for flat conversion (činžovní dům na jednotky) manages the entire process from audit through permits and construction to unit sales, advancing only when figures are confirmed. This service is most valuable when you lack the capacity or experience to coordinate architects, authorities, contractors and sales simultaneously. An owner with relevant expertise and dedicated time can manage alone.
Summary
- A project manager integrates the legal, construction and sales components into a single schedule and budget.
- The greatest value lies in areas where mistakes are costly: permits, construction and sales setup.
- Owners typically manage decisions about property and tenants well but struggle with coordinating trades and authorities.
- A paid audit and plan help support decision-making, with results delivered in 6 weeks.
What a project manager handles in flat conversion
Converting a rental building (činžovní dům) into marketable units is not a single project but several sequential ones: legal preparation, design and permits, building modifications, registration at the Czech Land Registry (katastr nemovitostí) and sales. Each has different specialists, timelines and risks. A project manager is the person who holds them in one plan and ensures they connect properly.
Practically, it involves three things: schedule (what must be complete before the next step begins), budget (including tracking changes against plan) and decision points (when the owner must decide and with what information). It does not replace the architect, lawyer or site manager. The goal is to ensure their work forms a coherent whole.
Role in each phase: audit, construction, sales
Audit and preparation
In this phase, the project manager gathers information about the building, verifies its legal and technical condition, commissions specialist reports and develops an economic model. The goal is to determine whether dividing into units makes sense. The typical uplift from selling the whole building versus selling units individually is 20–40%, but precise figures depend on feasibility. A paid audit and plan deliver results within 6 weeks; see Audit and Plan.
Permits and construction
This phase is the most demanding. The project manager coordinates the architect, authorities and contractors, verifies work scope against budget and ensures changes are assessed for impact before proceeding. Building modifications follow the Building Act (stavební zákon č. 283/2021 Sb.); whether a permit is required depends on the scope and is determined by the architect and building authority.
Unit sales
In this phase, the project manager manages the preparation of sales documents, purchase agreements and coordination with the lawyer and estate agent. Ownership of the property transfers only upon registration at the Czech Land Registry (katastr nemovitostí). The Land Registry office cannot decide before 20 days from notifying the owner (Czech Land Registry Act — katastrální zákon č. 256/2013 Sb.), and the average registration time is roughly 22 days. The project manager factors these timelines into the payment schedule and unit handover dates.
Three gates as control tools
A key part of professional management is discipline in transitioning between phases. The project passes through three gates: legal, permit and sales gate. Advancement depends on confirmed figures. The purpose is to stop the project in time if legal status, permits or demand prove misaligned with assumptions, rather than after construction costs have been incurred.
This 'uncomfortable' role is difficult for an owner to assume alone. Once time and money are invested, there is a tendency to continue. An independent management perspective helps decisions rest on numbers. See How it Works for details.
When you can manage alone and when professional management pays off
An owner naturally has strengths: knowledge of the building, tenants, repair history and decision-making authority over the property. If you have experience with construction or property sales, sufficient time and a reliable team of specialists, you can manage alone.
| Situation | Rather Alone | Rather with Project Manager |
|---|---|---|
| Experience with preparation and construction | Have it | Don't have it |
| Time capacity | Can dedicate regular time to the project | The building is just one of many activities |
| Scope of work | Minor modifications | Extensive modifications, multiple units |
| Ownership structure | Single owner | Heirs, multiple co-owners |
| Sales preparation | Have own contacts and experience | Need to prepare sales from scratch |
Ownership structure can be complicated. Co-owners' general right of first refusal has been abolished and applies only for 6 months from when co-ownership arises through inheritance (Section 1124 of the Czech Civil Code — občanský zákoník č. 89/2012 Sb.). For heirs, a coordinated approach from the start is worthwhile. Learn more on Who This Service Is For.
Difference in risk and time burden
With self-management, the owner bears the full time burden: meetings with architects, contractor oversight, authority liaison and sales preparation. It is intermittent work that sits poorly with other activities. Delays in one area cascade to others; for example, construction delays push back sales and financing.
Risks distribute similarly. With self-management, you face exposure to coordination errors, inadequately documented scope changes and poor sales timing. Professional management does not eliminate these risks but reduces the probability they will go unnoticed. Responsibility for decisions and financing always remains with the owner and project partners.
Transaction mechanics also matter. Cash payments are limited to 270,000 Kč per day under Czech law (zákon č. 254/2004 Sb.), so serious sales proceed without cash, typically through lawyer escrow. Tax implications of the sale (such as the holding period test or residential use under the Income Tax Act — zákon č. 586/1992 Sb.) should be discussed with a tax adviser or the Czech Tax Authority.
How to choose the level of involvement
The decision need not be 'all or nothing'. Three partnership models exist: Audit and Plan, End-to-End Delivery and Partnership / Joint Venture. A sensible approach is to begin with an audit, which gives you the figures to assess whether and how much management support you need.
With end-to-end delivery, the entire project is managed under one contract. When choosing, compare precisely what is in scope (which phases, which gates, who approves changes) and how responsibilities are allocated. Have a lawyer review the contract.
