How to Manage a 2,000-Unit Complex in Turkey: A Guide to Large Complexes and Mass Housing

Short answer: in a large complex, first establish the legal status (a multi-block development or a single property) and the management plan, and set up the boards and decision routes accordingly. Then build internal control with separated duties, a change history and period-end reconciliation. For repetitive work such as charges, collections and late payment penalties, test the software you use with your own data volumes.

What does scale change?

If each unit is charged a maintenance fee once a month, 2,000 units produce 2,000 × 12 = 24,000 charge records a year. Bank transactions, overdue balances and staffing needs depend on the complex's payment habits and services. To work out your own figures:

• How many bank transactions were there last year, and how many were transfers whose description did not show which unit they belonged to?
• How many units had an overdue balance each month?
• How many hours a month went into charges, recording payments and reconciliation?

Legal framework: status first

• Multi-block development (toplu yapı): several buildings on one or more zoning parcels, built to an approved site plan and linked by infrastructure, shared facilities and management (KMK Art. 66). In projects set up as a multi-block development, KMK Art. 66–74 apply. Not every complex with several blocks is automatically one; the land registry record and the management plan decide.
• Boards (in a multi-block development): each block is managed by its block owners' assembly for its own matters and its own common areas; the development's shared buildings, areas and facilities are managed by the development owners' assembly (Art. 69). The management plan can give this power to a board of representatives, whose members vote with as many votes as the units they represent. A board of representatives is not the only model in the law; which structure applies depends on the management plan.
• Meeting frequency: unless the plan sets another time, the boards of a multi-block development meet at least every two years (Art. 29).
• Management plan: a multi-block development has one management plan; since 22/05/2026 amending it needs the votes of two-thirds of the units represented (Art. 70, Law No. 7579). See the management plan guide.
• Manager: a person or a board from among the owners or from outside can be appointed (Art. 34). In a multi-block development, block managers and the development manager are appointed separately (Art. 71).
• Books: each board's resolutions are written in a notarised resolution book (Art. 32); if an auditor is elected, audit reports go in a separate certified book (Art. 41).

Organisation and internal control

Staffing follows the services the complex provides. The roles below are an example; in a small team one person may cover several.

Three pillars of internal control:

1. Separation of duties: the person posting charges is not the person recording payments; everyone has access only to their own work.
2. Change history: who created or changed each record, and when, can be traced.
3. Period-end reconciliation and an open items list: every month the bank balance is compared with the ledger. Items left open (transfers with no identified unit, overpayments awaiting refund, undistributed advances, expenses missing documents) are listed with their reasons at period end, given an owner and tracked until closed in the following period. No open items is the goal; not hiding them when they exist is the rule.

Financial set-up

Operating budget and budget tracking

Since 22/05/2026 the operating budget is approved by the owners' assembly; if there is no approved budget, the manager prepares a provisional one (Art. 37, see the operating budget guide). In a multi-block development, costs of common areas allocated to particular buildings are paid by the owners in those buildings, and costs of those allocated to all units by all owners (Art. 72). So plan the budget with a split between block and shared costs, and compare actuals with it every month.

Fee charges

At this volume, posting charges by hand every period increases the risk of missed periods, duplicate debts and wrong amounts. A good set-up:

• The charging rule is defined once (including different amounts per block) and applied the same way every period.
• Posting the same period twice is blocked.
• Exceptions are defined only on a basis such as the management plan or an assembly resolution. Being empty or not using common areas does not remove an owner's share (Art. 20, 72); empty units are not an exception.

Collections

• Bank transactions: transactions arrive in the system regularly and the bank balance can be compared with the ledger.
• Recording transfers to units: set a rule and an owner for transfers with unclear descriptions; write down how a single payment covering several units is split.
• Card payments: residents pay from their own panel; the contract and fees with the payment provider need to be assessed separately.

Late payments

An owner who does not pay their share of expenses and advances owes a late payment penalty at the rate of five per cent a month for the days they are late (Art. 20). Write the rate and method into an assembly resolution and apply the same rule to everyone (late payment penalty guide); put the steps for non-payment into a procedure (guide for when an owner does not pay).

Accounting

At this scale, auditors and boards may ask for journal, general ledger and trial balance records. Records tied to documents and dates mean reports are not squeezed into the days before a meeting.

Tracking by block

Boards look at the whole picture; block representatives look at their own block. Track balances and payments by block, budget versus actual with the block/shared split, and overall cash flow together. A block or phase running a budget deficit should not disappear inside the totals.

Resident communication and transparency

• Residents seeing their own balance, payment history and announcements in their panel reduces disputes.
• Announcements and reminders can go by email, SMS and app notification; assembly notices, however, follow the method in the law (signature or registered letter) (see the meeting guide).
• Requests and faults tracked with their status.

Personal data

A large complex processes the data of owners, tenants, staff and visitors together. Assess the data inventory, privacy notices, access permissions, retention periods and transfers abroad together. For Yonevo's hosting and access approach, see the Security and Data Protection pages.

Test the software with your own data

General selection criteria are in the software selection guide. For a large complex, also:

1. Load your own volume: during the trial, post one charging period for your real number of units; time the screens and reports yourself.
2. Concurrent use: try a day when accounting, collections and front desk staff work at the same time.
3. Block versus shared costs: check that you can charge a block-specific cost to that block only.
4. Separation of duties: check that each role sees only its own screens.
5. Data migration: import part of your past charges and payments; see how unmatched records are shown.

In Yonevo: monthly charges can be posted automatically and posting the same period twice is blocked; additional items are added with their own split, and for a block-specific cost other units can be left out of the charge. Card payments by residents are recorded as collections automatically; bank transfers pulled from the bank are recorded in the bank ledger, and you decide which unit they belong to. One person's single payment can be split across several units. The period balance report groups by block; there is no separate budget per phase. There are role-based permissions, data separation between properties and a change history. Pricing is calculated automatically up to 2,000 units, with an optional volume quote between 401 and 2,000 and a custom quote above 2,000 (pricing). The 2,000 threshold is a pricing threshold, not a performance limit or a performance commitment; measure your own volume during the trial.

Common mistakes

1. Setting up boards without knowing the legal status: the multi-block provisions apply only to projects set up as multi-block developments.
2. Relying on one person: records must belong to the management, not to an individual.
3. Applying the late payment penalty inconsistently: charging some owners and not others is unfair to those who pay on time.
4. Looking only at totals: a budget deficit in a block or phase may not show in the totals.
5. Hiding open items: items left open at period end should be reported with their reasons.

Frequently asked questions

Can a 2,000-unit complex be managed in one piece of software? Yes, with a suitable data model and workflows. Assess charges, collections, block-level tracking, permissions and reporting together, and test data volume and concurrent use with your own scenario.

How are fee charges automated in a mass housing development? The charging rule (including per-block amounts) is defined once and applied the same way every period; posting the same period twice is blocked. Exceptions need a basis.

Is a board of representatives compulsory? No. By law the development owners' assembly manages the development's common areas; the management plan can give that power to a board of representatives (Art. 69). Which model applies depends on your plan.

How is the late payment penalty applied in a large complex? At the legal rate of five per cent a month, for each late debt from its own due date. Write the rate and method into an assembly resolution and apply the same rule to everyone.
