Short answer: a commercial fit-out is almost always an alteration under Section 301 of PD 1096, the National Building Code — and alterations need a building permit before work starts. The mall's or landlord's fit-out approval is a separate, private process; it is not a government permit and it does not protect you from the penalties. The genuinely exempt works are a short, specific list, and most real fit-outs step outside it on day one, the moment a partition layout changes or a new circuit is pulled.
Trigger: altering, repairing, converting or adding to a building (PD 1096 §301) · Exempt: only the minor works in IRR §301.3 · Change of use: new Certificate of Occupancy, ₱5.00/sqm of area affected · Penalty for skipping: 100% surcharge on building fees, plus a fine up to ₱20,000 and/or up to 2 years' imprisonment
Every tenant fit-out in a mall, office tower, or leased commercial building runs through two entirely separate gates. They have different owners, different documents, and different consequences — and clearing one tells you nothing about the other.
Gate 1 — Landlord / Mall Fit-Out Approval (Private)
Governed by your lease and the building's tenant fit-out manual, not by law. The building administrator reviews your design against house rules: allowed working hours, ceiling and slab load limits, tapping points for power and water, protection of common areas, waste disposal, a construction bond, and the accreditation of your contractor. This is where most tenants spend their attention — because the landlord holds the keys, literally.
Gate 2 — Building Permit from the Office of the Building Official (Government)
Governed by PD 1096 and its 2004 Revised IRR. Section 301 is unambiguous: no person, firm or corporation shall "construct, alter, repair, convert, use, occupy, move, demolish and add any building/structure or any portion thereof" without first obtaining a building permit from the Building Official where the building is located. A leased unit inside somebody else's building is still a portion of a building/structure.
The failure mode is predictable: the tenant gets the mall's stamped fit-out plans, assumes that is the approval, and starts building. It surfaces later — at business permit application, at the fire inspection, at insurance claim time, or when the Building Official's annual inspection reaches the unit and finds work that never appears in any permit file.
Section 301.3 of the 2004 Revised IRR lists the works that do not require a building permit, "provided these shall not violate any provision of the Code and this IRR." For interiors, the relevant items are the repair works:
Read the verbs carefully, because the Code does: the exemption is for repair and replacement. The moment the work becomes an addition or an alteration — a new partition layout rather than a like-for-like replacement, a new opening, an added circuit, a relocated toilet, a mezzanine — the exemption stops applying. A repaint-and-refloor refresh may genuinely be exempt. A restaurant build-out in a bare shell is not, and neither is a "cosmetic" office refresh that quietly adds twelve workstations' worth of power and data.
Tick the work in your scope. The checker maps it against PD 1096 §301 and IRR §301.3, and shows which ancillary permits your drawings will need to carry.
A building permit for a fit-out is not one document. Section 301.2 of the IRR requires supplementary permits to be applied for together with it, and states plainly that "The Building Permit is null and void if not accompanied by the Ancillary Permits." There are seven:
| Ancillary permit | Who signs and seals the documents (IRR §302.3) |
|---|---|
| Architectural | Architect — or either an architect or an interior designer for architectural interior / interior design documents |
| Civil / Structural | Civil engineer |
| Electrical | Professional Electrical Engineer (PEE) |
| Mechanical | Professional Mechanical Engineer (PME) |
| Sanitary | Sanitary engineer |
| Plumbing | Master plumber |
| Electronics | Electronics engineer |
Lot survey plans are signed by a geodetic engineer. Signage, fencing, scaffolding, demolition and similar activities fall under accessory permits (IRR §301.2.b) rather than ancillary ones.
This is the single most common reason a fit-out application is bounced: the interior designer produced a beautiful set, the contractor's in-house electrician drew the panel schedule, and nobody with the right PRC licence sealed the electrical documents. The set gets returned, the fit-out programme slips two weeks, and the lease's rent-free construction period keeps ticking. If your scope touches power, aircon, plumbing or low-voltage systems, line up the MEPFS professionals at design stage, not at filing.
A recurring worry is that only the registered lot owner may pull a permit. Section 302.2 of the IRR says otherwise. The application requires a certified true copy of the OCT/TCT on file with the Registry of Deeds, the tax declaration, and the current real property tax receipt — and then adds, for the case where the applicant is not the registered owner, a duly notarized copy of the Contract of Lease or Deed of Absolute Sale.
Practically, that means two things for a tenant. First, you need the landlord's cooperation to obtain the title and tax documents, which is a negotiation to have before you sign the lease, not after. Second, your lease should say explicitly who files, who pays the permit fees, and who owns the improvements at the end of the term. Fit-out delays caused by a landlord slow to release documents are common enough that a well-drafted lease puts a deadline on it.
Turning a retail unit into a restaurant, an office into a clinic, or a warehouse bay into a showroom is not just an interior project — it is a change in occupancy classification, and the Code treats it as a distinct regulated event.
Section 309 of PD 1096 states that no building or structure shall be used or occupied, and no change in the existing use or occupancy classification of a building or portion of it shall be made, until the Building Official has issued a Certificate of Occupancy. Section 309.4.b of the IRR completes the picture: a building that already holds a Certificate of Occupancy "may further be issued other Certificates of Occupancy due to changes in use, whether partly or wholly, provided, that the new use/s or character/s of occupancy conforms with the requirement of the Code and its IRR." The IRR fee schedule prices it at ₱5.00 per square metre of the area affected.
The fee is trivial. The compliance consequences are not — a change of occupancy classification resets the fire safety requirements for the space: occupant load, exit width, travel distance, and which fire protection systems are mandatory. That is why a restaurant fit-out in a unit that was previously a dress shop so often uncovers an exit or extinguisher problem that the previous tenant never had. See our FSIC guide for how the classifications drive requirements.
Fit-out teams routinely treat the Bureau of Fire Protection as a closing step. It is actually two steps, one at each end of the project:
Before: FSEC — Fire Safety Evaluation Clearance
The BFP reviews your fit-out plans on paper — exits, occupant load, fire separation, detection and suppression — as part of the building permit stage. A layout that blocks or narrows an existing egress path is cheap to fix here and expensive to fix once the ceiling is closed.
After: FSIC — Fire Safety Inspection Certificate
Section 309.2 of the IRR sets out the handover: the Office of the Building Official endorses the notification for final inspection to the City/Municipal Fire Marshal, who shall issue the FSIC within five (5) working days if the fire safety requirements are met. No FSIC, no occupancy — and for the business itself, no business permit.
Section 212 of the 2004 Revised IRR: for constructing, installing, repairing, altering or causing any change in the occupancy/use of any building/structure or part thereof without any permit, a surcharge of 100% of the building fees shall be imposed. If work merely started while the permit was still in process, the surcharge is staged by how far you got — 10% at excavation, 25% at foundation, 50% for superstructure up to 2.00 m above established grade, and 100% above that.
Section 213 adds the penal layer: it is unlawful to erect, construct, enlarge, alter, repair, move, improve, remove, convert, demolish, equip, use, occupy or maintain any building contrary to the Code, punishable on conviction by a fine of not more than ₱20,000 or imprisonment of not more than two years, or both — and in the case of a corporation, partnership or association, the penalty is imposed on the officials responsible for the violation. For a company officer signing off on a fit-out programme, that last clause is the one worth re-reading.
There is a quieter cost too. Unpermitted alterations sit outside the as-built record, which is exactly what an insurer looks for after a fire or a flood, what a buyer's due-diligence team looks for at exit, and what your next annual electrical safety inspection has to certify against. Work that legally does not exist is difficult to certify.
Two timing figures from the Code are worth planning around. Under §304, the Building Official issues the permit within fifteen days from payment of the required fees — the clock starts at payment, not at filing, and the review before that is where real applications sit. And under §305, a permit expires if work is not commenced within one year, or if work is suspended or abandoned for 120 days. Fit-outs stalled by a delayed tenant opening have died on that second clause.
Section references and fee figures are taken from the text of PD 1096 and its 2004 Revised Implementing Rules and Regulations as published by the DPWH. The national fee schedule in the IRR is a floor, not a ceiling — many LGUs have updated their rates by local ordinance since 2005, and the classification of interior works (full building permit vs. a locally-named renovation or minor-works permit) varies between Offices of the Building Official. Confirm both with your local OBO before budgeting.
Does a commercial fit-out need a building permit?
Usually yes. PD 1096 §301 requires a permit to construct, alter, repair, convert, move, demolish or add to any building or portion of it. Only the minor construction and repair works listed in IRR §301.3 are exempt — essentially like-for-like replacement of finishes, ceilings, doors, windows, flooring and non load-bearing partitions.
Is landlord or mall fit-out approval the same as a building permit?
No. One is contractual, governed by your lease and the tenant fit-out manual; the other is statutory, issued by the Office of the Building Official. Clearing the mall's design review does not make unpermitted work lawful.
Can a tenant apply for the permit without owning the lot?
Yes. IRR §302.2 expressly provides for a non-owner applicant, who submits a duly notarized Contract of Lease (or Deed of Absolute Sale) in addition to the owner's title, tax declaration and current real property tax receipt.
What is the penalty for building a fit-out without a permit?
A surcharge of 100% of the building fees under IRR §212 — or a staged 10/25/50/100% if work merely started while the permit was pending — plus the §213 penalty of a fine up to ₱20,000, imprisonment up to two years, or both, imposed on responsible officials in the case of a corporation.
Do I need a new Certificate of Occupancy if I change from retail to a restaurant?
Yes. PD 1096 §309 bars any change in use or occupancy classification until the Building Official issues a Certificate of Occupancy for it, and IRR §309.4.b allows further certificates for changes in use. The IRR prices the change in use/occupancy at ₱5.00 per square metre of area affected — and the change also resets your Fire Code requirements.
Which professionals must sign the drawings?
Per IRR §302.3: architect (architectural; an interior designer may sign architectural interior documents), civil engineer (structural), PEE (electrical), PME (mechanical), sanitary engineer (sanitary), master plumber (plumbing), electronics engineer (electronics), geodetic engineer (lot survey). Wrong-profession signatures are a standard reason applications are returned.
