What Is SLF (Sertifikat Laik Fungsi)? Bali Building Compliance Guide

An SLF (Sertifikat Laik Fungsi, “Certificate of Functional Worthiness”) is the Indonesian building occupancy certificate that legally confirms a structure is safe and suitable for its declared use. Since the 2021 Omnibus Law reforms, no building in Indonesia can be legally occupied, rented out, or operated commercially without a valid SLF issued after inspection. For Bali villa owners, SLF is the licence that turns a built villa into a legally rentable business asset. This guide explains what SLF covers, how to obtain one, what it costs, and what happens if you operate without it.

SLF and its predecessor, IPB

SLF replaced the older IPB (Izin Penggunaan Bangunan) as part of the regulatory streamlining under UU 11/2020 (Omnibus Law) and PP 16/2021. The core idea is the same: before a building is used, a qualified inspector must certify that it was constructed according to the building permit (PBG) and meets current safety and functional standards.

What SLF actually certifies

• Structural integrity (foundations, columns, load-bearing walls, roof).
• Fire safety (escape routes, extinguishers, smoke detection, where required).
• Electrical systems (load calculation, circuit protection).
• Water and sanitation (water quality, septic, drainage).
• Accessibility and safety (stairs, railings, glazing).
• Compliance with the approved PBG design.

SLF is issued by the regency building authority (Dinas PUPR / DPMPTSP) after submission of an inspection report prepared by an independent certified assessor (Pengkaji Teknis).

Who needs an SLF?

Every building. In practice this means:

• New villas before first occupancy.
• Existing villas seeking to be marketed as short-term rentals.
• Any building applying for a tourism business licence (TDUP), restaurant licence, or similar.
• Hotels, apartments, commercial buildings, offices, warehouses.
• Renovations that change use, floor area, or structural load.

Very small residential buildings below threshold areas (typically under 100 sqm single-dwelling) may be exempt, depending on the regency.

SLF validity periods

• Residential (private home): 20 years.
• Non-residential (villa rental, hotel, commercial): 5 years, renewable.

Expired SLFs invalidate the occupancy permit – the building is technically no longer legally in use and commercial operations can be ordered halted.

SLF and PBG – two permits, one process

PBG (Persetujuan Bangunan Gedung) is the building permit – obtained before construction, based on architectural drawings. SLF is the occupancy certificate – obtained after construction, based on the as-built condition. You cannot get SLF without PBG. If your villa was built without PBG, SLF is impossible until the PBG is retrospectively issued (sometimes feasible, sometimes blocked by zoning or setbacks).

The SLF application process

Step 1 – Engage a certified Pengkaji Teknis

An independent certified assessor (individual or firm) inspects the building against the PBG drawings and current codes. They produce a technical report.

Step 2 – File at DPMPTSP / online OSS-building module

The inspection report, as-built drawings, PBG, land certificate, and identity of the owner are submitted. The authority may schedule a site verification.

Step 3 – Issuance

If no deficiencies, SLF is issued within 3–8 weeks. If deficiencies exist, the owner is given a remediation period before re-inspection.

Consequences of operating without SLF

• Inability to get TDUP – no legal short-term rental operation.
• Booking platform removal – Airbnb, Booking.com, and Agoda increasingly require TDUP/SLF documentation.
• Administrative sanctions – warnings, temporary closure orders, fines.
• Tax exposure – unlicensed rental income raises flags with DJP (tax office).
• Demolition risk – in extreme cases of zoning or setback violations, demolition orders have been issued.
• Diminished resale value – buyers’ due diligence will discover missing SLF and reduce offers.

SLF and the Bali crackdown on illegal villas

Since 2023, Bali regency authorities – especially Badung and Gianyar – have intensified enforcement against unlicensed short-term rentals. Villas marketed as rentals without TDUP/SLF have been publicly listed, fined, and in some cases shut down. Owners expecting to quietly operate without the paperwork are playing against rising enforcement momentum.

SLF for existing villas built before 2021

Villas built under the old IMB/IPB regime generally need to transition to PBG/SLF when they next apply for a licence, when the building is modified, or when ownership transfers. Many older villas operate on expired IPBs – legally precarious under the new regime.
