How to Inform Tenants About Converting a Multi-Unit Building Without Legal Risk

When to Tell Tenants About Converting the Building

The right time comes after you have completed your legal and economic analysis, not before. If you announce the intention to tenants when you are still unsure whether the building is technically and legally suitable for subdivision into separate units, you will have to revise your communication later and lose their trust.

In practice, it pays to follow the project logic that passes through three stages (legal, planning permission, sales stage) and only proceeds to the next phase with confirmed figures. We recommend informing all tenants only after the legal stage, when it is clear whether and to what extent the project will proceed. How these stages connect is described on our How It Works page.

At the same time, do not delay communication for too long. Tenants will notice changes in the building (viewings, surveys, dealings with authorities) and rumours are usually worse than factual information.

What to Prepare Before Communicating

Before your first conversation, you must have verified documentation in place, otherwise you will not be able to answer basic questions.

1. An overview of all rental agreements: term (fixed-term, indefinite), rent amount, and any special clauses relating to sale or right of first refusal.
2. Payment status and any previous disputes with tenants.
3. A rough timeline: what will happen and when it will affect tenants (viewings, surveys, any construction work).
4. Designation of a single point of contact who will answer questions.
5. A decision on what offer you wish to make to tenants—for example, the option to purchase their unit or to continue the tenancy.

Legal framework and realistic timeline will be established by our Audit and Plan service—a paid feasibility study delivered within 6 weeks.

How and What to Communicate in Order

A three-step approach works best: personal notification, written letter, and open opportunity for questions.

1. Personal meeting or gathering in the building. Explain your intention briefly and factually. No one should learn of the changes from a letter on the door.
2. Written notification with proof of delivery. Deliver it in a manner that can be verified and keep a copy. The letter should summarise what you have said, nothing more.
3. Contact details and timeframe for questions. State who the point of contact is and when they will be available.

What the Notification Should Include

• That the owner is preparing to subdivide the building into residential units with a view to selling them.
• That existing rental agreements remain in force.
• What will and will not change in the near term (viewings, surveys, contact arrangements).
• Who the designated contact is.
• That tenants will be kept informed of further steps in writing.

What to Avoid

• Verbal commitments about price, timescales or conditions that you have not confirmed.
• Suggesting that tenants must leave or must purchase their unit.
• Sharing tenants' personal data between yourselves; for data protection guidance, consult the Czech Office for Personal Data Protection (Úřad pro ochranu osobních údajů).

Tenant Rights and Owner Protection

Subdividing the building into separate units does not terminate rental agreements or deprive tenants of protection. That is why it is important not to proceed in a way that makes communication appear to be pressure to vacate.

Under Section 2221 of the Czech Civil Code No. 89/2012 Coll., the purchaser of a leased unit assumes all rights and obligations under the lease. The buyer of a unit therefore takes over the existing tenancy. The lessor may only terminate a lease for reasons set out in law (Sections 2288 et seq. of the Civil Code), or with court approval; the intention to sell units is not such a reason. Always assess your specific situation according to the lease terms and current law.

Before communicating with tenants, we recommend having a lawyer review your agreements; the legal assessment of your specific property goes beyond the scope of this article.

How to Prevent Disputes and Project Delays

Most conflicts do not stem from the project itself, but from tenant uncertainty and lack of trust. Predictability helps avoid this.

• A single point of contact and consistent communication method. Tenants should not receive conflicting information.
• Written record. Keep a note of what was communicated and when. In the event of a dispute, the proof is the delivery date and the letter's content.
• Keep tenancy matters separate from sales matters. Continue to handle repairs, utility bills and normal operations as usual.
• Respect for privacy. Give notice of viewings in advance and agree a time with the tenant.
• Keep tenants updated. As soon as your plan or timeline changes, inform them in writing before they hear it elsewhere.

Tenants can delay the project chiefly by refusing viewings or by taking legal action or appealing to an authority. Factual and proper communication reduces this risk, but does not eliminate it entirely.

What to Do Now

First, prepare your documentation; only then plan your first conversation with the tenants.

1. Compile an overview of all rental agreements (term, rent, special clauses) and payment status.
2. Have the legal and technical feasibility of subdividing the building verified.
3. Appoint a point of contact and draft a brief notification letter.
4. Plan the sequence: personal notification, written letter, space for questions.
5. Consider whether you want to implement the project yourself or with a partner.

If you want to understand the value created by subdivision, try our Potential Calculator as a rough guide; the typical value difference between selling the whole building and selling units individually is typically 20–40%, though the exact figure will only be determined by a feasibility study.
