SLF Building Certification Requirements in Indonesia – Everything You Need to Know in 2025

In Indonesia, having an SLF (Sertifikat Laik Fungsi) is not just a formality—it is a legal necessity for any building to be considered safe, functional, and eligible for official use. Whether you own a commercial property, residential complex, hotel, office building, or villa, obtaining an SLF certificate is required before the building can be used or occupied.

As a trusted legal service based in Bali, The Bali Lawyer offers full legal support to clients throughout Indonesia, including Jakarta, Surabaya, Lombok, Bandung, and Java. This comprehensive guide outlines the latest SLF building certification requirements in 2025 and how to meet them efficiently and legally.

What Is an SLF (Sertifikat Laik Fungsi)?

SLF, or Building Function Worthiness Certificate, is an official document issued by the local government confirming that a building:

  • Has been constructed according to its approved plans and permits (PBG)

  • Is structurally sound and safe for use

  • Meets technical, health, safety, environmental, and accessibility standards

  • Is legally allowed to be used for its intended function

It is the final milestone in the legal construction process and a prerequisite to using the building for occupancy, rental, or commercial operation.

Why SLF Certification Is Mandatory

SLF certification is regulated under Government Regulation No. 16 of 2021 and enforced at the provincial and municipal levels. Without an SLF:

  • You cannot legally operate or occupy the building

  • Business licenses may be denied or revoked

  • Insurance coverage may be invalid

  • Utility services such as water and electricity may be withheld

  • Your building may face penalties, usage suspension, or closure

The Bali Lawyer ensures that your building complies with every requirement so that you can secure your SLF without legal obstacles.

Who Needs an SLF Certificate?

SLF certification is mandatory for all completed buildings in Indonesia that meet the following criteria:

  • Commercial buildings (offices, retail spaces, restaurants, etc.)

  • Public-use buildings (schools, hospitals, auditoriums)

  • Industrial buildings (warehouses, factories)

  • Residential complexes (apartments, condominiums)

  • Hospitality properties (villas, resorts, hotels)

  • Government or institutional buildings

If the building is used or accessed by the public, rented out, or operates commercially, it must be certified.

When to Apply for SLF Certification

The SLF must be obtained after construction is completed but before the building is used or operated. The application can only proceed once the building has:

  • Completed construction in accordance with PBG (Persetujuan Bangunan Gedung)

  • Been inspected by relevant professionals

  • Been declared compliant with its technical and functional requirements

SLF is also required when transferring ownership, selling the property, or applying for major renovations or expansions.

SLF Certification Validity Period

The validity of an SLF depends on the type of building:

  • Residential buildings: Valid for 20 years

  • Non-residential or public/commercial buildings: Valid for 5 years

Upon expiry, the SLF must be renewed by undergoing another round of inspection and documentation.

SLF Building Certification Requirements – What You Must Prepare

To apply for SLF, you must fulfill legal, administrative, and technical requirements. Below is a complete checklist of the documents and conditions needed to apply in 2025:

1. Valid PBG (Persetujuan Bangunan Gedung)

Before applying for SLF, your building must already have a PBG permit. This document confirms that the building was authorized for construction and complies with planning and zoning regulations.

Without a valid PBG, your SLF application cannot proceed.

2. Land Ownership or Usage Proof

You must submit legal proof that you own or have the legal right to use the land where the building is constructed.

Accepted documents include:

  • SHM (Sertifikat Hak Milik)

  • HGB (Hak Guna Bangunan)

  • Lease agreements for long-term property use

  • AJB (Sale and purchase agreement)

3. As-Built Drawings and Final Construction Documents

You are required to submit complete as-built drawings that reflect the actual completed structure. These must be prepared and signed by certified architects and engineers.

Documents include:

  • Floor plans, elevations, and building sections

  • Structural system diagrams

  • Mechanical, electrical, plumbing layouts (MEP)

  • Fire safety system plans

  • Drainage and sanitation system

  • Accessibility features (ramps, lifts, accessible toilets)

  • Photographs of the completed building

4. Supervision and Construction Reports

Construction must be supervised by certified professionals who must submit:

  • Final supervision reports (Laporan Pengawasan)

  • Statement confirming that construction followed PBG-approved plans

  • Confirmation that safety standards were met

  • Reports on fire systems, building materials, and quality control

These reports must be submitted with professional licenses (SIPB) for the supervising architect and engineer.

5. Building Inspection Coordination

After documentation submission, local government agencies such as Dinas Cipta Karya or Dinas PUPR will conduct a site inspection. The inspection team will assess:

  • Whether the actual construction matches the approved design

  • Operational safety of fire exits, lifts, electrical systems

  • Accessibility and environmental features

  • Functional usability based on intended building purpose

The Bali Lawyer will assist in scheduling, coordinating, and preparing your building for inspection to ensure smooth approval.

6. OSS RBA Submission

The entire SLF application process is done via the OSS RBA (Online Single Submission – Risk-Based Approach)platform. The required steps include:

  • Registering or updating your NIB (Nomor Induk Berusaha)

  • Uploading all documentation

  • Declaring building classification and risk level

  • Completing self-assessment and declarations

We handle this process entirely on your behalf, ensuring compliance and timely progress tracking.

7. Taxpayer Information (NPWP) and NIB

You must submit a valid Tax ID (NPWP) and Business Identification Number (NIB) if the building is used for business purposes. These are mandatory for companies, PT PMA, and foreign investors operating in Indonesia.

8. Statement of Responsibility

The building owner must provide a signed declaration stating:

  • All information and documents are accurate

  • The building will be used in accordance with its intended function

  • The owner is responsible for future maintenance and legal compliance

9. Utility System Approval (Optional)

If applicable, approvals or installation certificates from:

  • PLN (electricity provider)

  • PDAM (water supply)

  • Fire and emergency system providers

These may be required based on the building’s size and complexity.

  • Incorrect or missing OSS RBA data entries

SLF Renewal Requirements

  • Resubmitting technical and compliance documents

  • Scheduling a new inspection

  • Updating NIB or ownership data if necessary

  • Re-certifying your building’s usage and safety
