Renovating a flat: which works need consent, what to do with a tenant in place, how to contract a builder.

01

Inside your own flat: what is free, what is not

A unit owner may use and arrange the inside of their unit as they wish; works touching the building’s load-bearing system, common areas and external appearance need the other owners’ consent. The law puts it in two sentences: owners must preserve the building’s maintenance, architecture and appearance; construction, repair, installation and paint changes in common areas, on the facade and in load-bearing elements may be made only with the written consent of four fifths of the unit owners (Condominium Law No. 634, Art. 19).

In practice, painting, cabinetry, kitchen and bathroom renewal, flooring and internal doors inside the flat need no consent. Enclosing a balcony, facade colour, external joinery, the position of an air-conditioning unit, intervention in shared installations (risers, main pipes, flues) and removing a load-bearing wall depend on the owners’ decision; the management plan may set stricter rules.

02

Municipal permit: simple repair versus substantial alteration

Works that need no building permit are listed in the law: pointing, internal and external plaster, paint, gutters, joinery, floor and ceiling finishes, electrical and plumbing repairs, roof repair and re-tiling, and other alterations and repairs that do not affect load-bearing elements (Zoning Law No. 3194, Art. 21/3). These can be done without applying to the municipality.

Works affecting the structure (removing walls, touching columns and beams), changes of use, additions to the facade or roof, and merging or splitting units are substantial alterations; they need an alteration permit from the municipality and, where required, a structural project. Substantial alteration without a permit can end in an administrative fine and a demolition order (Arts. 32, 42).

03

Listed and historic buildings

Many apartment buildings in Beyoğlu, Nişantaşı and along the Bosphorus are listed as cultural assets or lie within conservation areas. In these buildings, changes to the facade, windows, internal partitions and sometimes interior decoration are subject to the Regional Conservation Board’s consent (Law No. 2863 on the Protection of Cultural and Natural Assets). Simple repairs need the board directorate’s permission; substantial intervention needs a board decision and an approved project. Unauthorized work carries a penalty and an obligation to restore; at the survey, the title and listing status are the first items checked.

04

Renovation while a tenant is in place

The landlord may carry out improvements and alterations that do not require termination of the lease and that the tenant can be expected to tolerate; during the works the landlord must consider the tenant’s interests, and the tenant’s rights to a rent reduction and compensation are reserved (Turkish Code of Obligations No. 6098, Art. 320). The tenant must tolerate necessary repairs; works that remove comfort for a long period call for prior notice, a reasonable period and, where applicable, a temporary reduction.

The tenant, in turn, may make alterations only with the landlord’s written consent; at the end of the lease the landlord cannot demand restoration of consented alterations, and the tenant cannot claim the value added unless agreed in writing (Art. 321). Any renovation permitted to a tenant should therefore be in writing, stating what will be done and what happens at the end of the lease.

05

Contractor agreement and warranty

Renovation work is legally a contract for work: the contractor must perform the work as agreed and the client must pay the price (TBK Art. 470 ff.). If a lump-sum price is agreed, the contractor cannot raise it even if the work requires more effort and cost than expected, except in unforeseeable extraordinary circumstances (Art. 480). This is the legal basis of the rule “nothing outside scope without written approval”.

For defective work the client must inspect within a reasonable time after handover and notify the defect; hidden defects may be notified when they appear (Arts. 474–477). The agreement should contain the itemized job list, material brands, schedule, payment plan, warranty period and handover record; payments should be tied to work stages. An invoice is essential both for warranty and for tax.

• —Contractor’s name, tax number and signing authority
• —Job list and material choices (brand, model, quantity)
• —Price: lump sum or unit rates; how extra work is priced and the written-approval condition
• —Schedule and payment plan; what happens on delay
• —Handover record, snag list and completion period
• —Warranty period and scope; delivery of manufacturer warranty documents
• —Site rules: working hours, debris and lift use, notice to neighbours

06

Renovation costs and rental income tax

Maintenance and repair costs for a let home are deducted from revenue, if documented, when the actual expense method is chosen in the rental income return; expenditure that enlarges or extends the property and adds to its value is not a direct expense but is taken into account through depreciation (Income Tax Law No. 193, Art. 74). Under the lump-sum method these costs are not deducted separately. Invoices should therefore be issued in the owner’s name and kept; see the rental income tax guide.
