Presidential Decree 1096 — the National Building Code of the Philippines — was signed by Ferdinand Marcos Sr. in 1977. It has governed every building permit, every structural design, and every construction project in the country for 49 years. The Angeles City collapse finally broke the political inertia that kept it untouched.
On May 24, 2026, a nine-storey building under construction in Barangay Balibago collapsed at 3:00 AM, killing at least five people and burying construction workers while they slept. The investigation revealed what engineers had warned about for years: a regulatory system with a nearly 50-year-old foundation law, fragmented enforcement, and no binding requirement for structural peer review on mid-rise buildings.
Two bills responded within days. House Bill 6615 was filed by Rep. Romeo Momo Sr. — whose district is in Pampanga, where the collapse happened. Senate Bill 2158, branded the "New Philippine Building Act," was filed by Sen. Raffy Tulfo. A Senate probe has been requested. DOLE suspended its own regional director over inspection failures.
The Philippine construction industry is now in a period of heightened regulatory scrutiny and legislative change. If you are a developer, contractor, property owner, or anyone planning to build in the Philippines — this is what you need to understand, and what you need to do right now.
Why Is the 49-Year-Old National Building Code Being Replaced?
Presidential Decree 1096, signed on February 19, 1977, is the foundational law for all building construction in the Philippines. It establishes the requirements for building permits, the role of the Office of the Building Official (OBO), the minimum design standards, and the penalties for violations. It has been the legal backbone of Philippine construction for longer than most of the country's engineers have been alive.
PD 1096 requires building permits, mandates structural plans sealed by a licensed engineer, and gives the OBO enforcement authority. But it was written before modern high-rise construction became widespread in provincial cities, before digital documentation existed, before NSCP seismic provisions were developed, and before inter-agency coordination between DOLE, DPWH, and local government units became critical. The law has provisions — but it lacks the enforcement teeth and modern standards that 2026-era construction demands.
Critics and structural engineers have identified five systemic gaps that the Angeles City collapse exposed with fatal clarity:
PD 1096 requires structural drawings sealed by a licensed engineer. It does not require an independent peer review of those drawings for buildings in the 4–15 storey range where the collapsed Angeles City building operated. In countries with modern building codes, independent peer review by a second licensed structural engineer is mandatory for buildings above a certain height. In the Philippines, a single engineer can design, seal, and submit plans for a 9-storey building with no independent verification.
DOLE issued a work stoppage order on the Angeles City site in September 2025 — and lifted it one month later after surface-level corrections. DOLE then conducted zero follow-up inspections as the building grew from roughly 4 storeys to a reported 10-floor structure with a rooftop swimming pool. Meanwhile, the local OBO, DPWH, and DILG operated with no shared inspection records and no unified enforcement protocol. Each agency inspected independently — or not at all — with no system to flag compounding violations.
The approved permit for the Angeles City building reportedly covered nine storeys. A 10th floor with a swimming pool was reportedly under construction — an unauthorized addition that would have added enormous unaccounted structural load. Under PD 1096, unauthorized work is a violation subject to stop-work orders and fines. But the penalties in a nearly 50-year-old law — and the enforcement capacity to apply them consistently — have not kept pace with the scale of unauthorized additions now common in Philippine mid-rise construction.
PD 1096 was written before the Philippines had comprehensive seismic design provisions (NSCP 2015), before typhoon loading standards were formally codified, and before modern reinforced concrete ductility requirements were developed. The structural design code (NSCP 2015) exists separately and has been updated — but PD 1096, the enforcement vehicle, still operates on 1977-era frameworks for inspection, verification, and penalty structures that do not reflect modern structural engineering practice.
PD 1096 requires permit documents before construction. It does not require documented materials testing during construction, continuous engineering supervision records, digital as-built plans after construction, or any mechanism to verify that what was built matches what was permitted. A building can be permitted, built, and occupied with no continuous documentation trail — making post-failure investigation, as well as proactive enforcement, extremely difficult.
HB 6615 — Rep. Momo's House Bill Explained
House Bill 6615 was filed on May 26, 2026 by Representative Romeo Momo Sr. of the 1st District of Pampanga — the province where the Angeles City collapse occurred. Rep. Momo cited the collapse as direct evidence that "the Philippines urgently needs a modern building law that goes beyond the 1977 code in design standards, inspection enforcement, and disaster resilience."
As of June 5, 2026, HB 6615 is a filed House Bill under Congressional deliberation. It has not been passed by the House, transmitted to the Senate, or signed into law. All construction compliance requirements remain governed by the existing National Building Code (PD 1096) and NSCP 2015. This article analyzes what the bill proposes — not what the current law requires.
Based on filed text and official statements, HB 6615 proposes to:
| Proposed Reform Area | What HB 6615 Would Require |
|---|---|
| Structural Peer Review | Mandatory independent peer review by a second licensed structural engineer for all buildings 5 storeys or higher — drawings must be reviewed and co-sealed before permit issuance |
| Construction Phase Inspections | Scheduled inspection requirements at defined construction milestones — foundation completion, structural frame completion, and before occupancy — with licensed engineer certification required |
| Permit Change Enforcement | Stricter enforcement mechanism for unauthorized vertical additions — any increase in floor count or major structural load after permit issuance triggers automatic re-analysis and OBO re-approval requirement |
| Disaster Resilience Standards | Explicit incorporation of updated seismic and typhoon design standards by reference to NSCP 2015, with a mechanism for automatic future code updates |
| Materials Certification | Documentation requirement for concrete cylinder testing and rebar mill certificates at defined construction stages for buildings above a defined height threshold |
| Penalties Update | Substantially increased criminal and civil penalties for building code violations — amounts to be updated from 1977 levels to reflect current construction economics |
SB 2158 — Sen. Tulfo's New Philippine Building Act
Senate Bill 2158, branded the New Philippine Building Act, was filed by Senator Raffy Tulfo on May 25, 2026. Sen. Tulfo framed the bill as a necessary modernization of construction law that the Philippines has delayed for too long, stating that the Angeles City collapse "is the consequence of allowing a 1977 law to govern 2026-era construction."
SB 2158 focuses more explicitly on:
- Modern engineering technologies — explicit authorization and integration of 3D structural modeling, BIM (Building Information Modeling), and digital permit documentation as accepted compliance tools
- Inter-agency coordination — creation of a unified building compliance database accessible to DOLE, DPWH, DILG, and local OBOs — ending the siloed inspection system that failed in Angeles City
- Disaster resiliency as a national priority — framing earthquake and typhoon resilience not as technical standards but as national public safety obligations with specific performance requirements
- Accountability chain — clearer criminal liability assignment across the design engineer, contractor, developer, and building official for each category of code violation
- Post-occupancy monitoring — provision for periodic structural inspection of high-rise buildings after completion, not just during permitting and construction

Get a Free Compliance ReviewThe 5 Changes That Would Matter Most — An Engineering Perspective
From a structural engineering standpoint, the two bills overlap on five changes that would have the greatest impact on construction safety in the Philippines. These are not legal opinions — they are the engineering observations of what gaps in the current system cause the most catastrophic outcomes.
This is the single most impactful change either bill proposes. An independent second engineer reviewing structural calculations and drawings before permit issuance would catch column undersizing, inadequate seismic detailing, and soft-storey configurations that a single overworked engineer may miss or a developer may pressure to ignore. Every high-income country with modern building codes has this requirement. The Philippines does not — and the results are visible in every major structural failure over the past 30 years.
A single centralized database where DOLE, DPWH, DILG, and local OBOs record and share inspection findings would have caught the Angeles City situation. DOLE's work stoppage record would have been visible to the OBO that continued processing the project. A unified system cannot eliminate bad actors — but it eliminates the ability to exploit fragmented record-keeping. Construction projects in the Philippines should not be able to fall through the cracks between agencies.
Concrete cylinder test records and rebar mill certificates must be documented at defined construction milestones and tied to the permit record. Currently, a developer can submit a compliant structural plan for permitting and then build with whatever materials are available and affordable — with no documentation trail. Materials testing requirements would not prevent all substitutions, but they create a legal paper trail that makes prosecuting violations far more effective and deters systematic quality reduction.
Any addition of floors beyond the approved permit — or any significant added structural load like a rooftop pool or mechanical plant — must trigger an automatic structural re-analysis requirement with no exceptions. The current system requires this in theory; the new law would need to create an enforcement mechanism — such as utility connection denial or occupancy permit withholding — to ensure compliance without requiring pro-active OBO inspection of every ongoing project.
Criminal penalties under PD 1096 were calibrated to 1977 construction economics. The maximum fines represent a negligible deterrent for a developer with a multi-storey project. Modern building acts globally set penalty levels as a percentage of project cost — which scales with the scale of the violation. Without this update, the new act risks the same enforcement gap as the old one: nominal fines that are priced in as a cost of doing business rather than a genuine deterrent.
What the EXISTING Law Already Requires — and Is Being Ignored
Before discussing what the proposed new law would change, it is essential to be clear: the existing National Building Code (PD 1096) already requires most of what failed in Angeles City. The problem is not solely that the law is outdated. The problem is also that the existing law is systematically under-enforced.
Building permit before construction · Structural drawings sealed by a licensed engineer · Column design for full building height · Structural re-analysis for any change in floor count or major loads · Stop-work authority for OBO over unsafe construction · Criminal penalties for violations. The Angeles City building reportedly violated several of these existing requirements — while continuing to operate with no effective enforcement.
This distinction matters for developers and contractors: the new law is coming. But the existing law is already being enforced more aggressively in the post-collapse environment. Enforcement actions, stop-work orders, and OBO inspections have increased nationwide. Do not wait for the new act to ensure your project complies — comply with what exists now.
Current Law Requirements — What PD 1096 + NSCP 2015 Already Demand
- Building permit from the local Office of the Building Official before any construction commences
- Structural drawings (plans) produced and sealed by a licensed civil or structural engineer
- Structural design must cover the full planned building height — columns sized for cumulative floor loads from the topmost approved floor to the foundation
- Any addition of floors beyond the approved permit requires a revised structural design, re-analysis, and new permit from the OBO — no exceptions
- Any addition of significant structural loads (rooftop pool, heavy mechanical equipment, water tanks) must be incorporated into the structural analysis and OBO-approved
- NSCP 2015 Section 208 seismic load compliance for all buildings in the Philippines — base shear analysis, seismic zone, soil profile, ductile detailing
- NSCP 2015 Section 207 wind load compliance — especially critical with typhoon season active June through November
- All work must follow approved structural drawings — material substitutions require engineering review and OBO notification

What Developers and Contractors Must Do NOW — Before the New Law Passes
The new building act may take one to two years to pass. But enforcement of the existing law is happening today, intensified by the post-collapse political pressure on every government agency involved in building oversight. Here is what every developer, contractor, and property owner must do before any new legislation takes effect.
| Action | Why It Matters Now | Who Must Act |
|---|---|---|
| Audit your existing permits | Confirm every floor and structural load on your current project is within your approved permit scope. Any discrepancy is a stop-work order risk under the current inspection surge. | All developers with active projects |
| Verify structural drawings cover your actual building height | If you added floors or rooftop loads after original design, have a licensed structural engineer verify the drawings still cover the actual build. If not, re-analysis is required under PD 1096. | Any developer who modified scope post-permit |
| Document materials testing | Even where not yet legally required, concrete cylinder records and rebar mill certificates create a defensible record if your project is inspected or investigated. Start documenting now — it will be required under the new act anyway. | All active construction projects |
| Engage a licensed engineer for on-site supervision | Formal, documented engineering supervision is your most effective protection against both structural failure and regulatory action. DOLE inspects for safety; OBO inspects for code compliance — having a licensed engineer on record satisfies both. | All mid-rise and commercial projects |
| For completed buildings: structural assessment | If you own a completed building where you have questions about the original structural design's adequacy — especially if built before 2010 or with unauthorized modifications — a rapid structural assessment now is vastly cheaper than the alternative. | Property owners, developers, building managers |
HB 6615 vs. SB 2158 — Key Differences at a Glance
Both bills address the same core failures, but with different emphasis areas.
| Feature | HB 6615 (House) | SB 2158 (Senate) |
|---|---|---|
| Primary Focus | Structural safety enforcement, peer review, inspections | Disaster resilience, modern tech integration, accountability |
| Peer Review | ✅ Mandatory for 5+ storeys | ✅ Proposed — threshold under deliberation |
| Digital Documentation | Not yet explicitly detailed | ✅ BIM and digital permits explicitly authorized |
| Inter-Agency Database | Partially addressed | ✅ Unified compliance database specified |
| Post-Occupancy Inspection | Not specified | ✅ Proposed for high-rise buildings |
| Penalty Level | ✅ Substantially increased | ✅ Increased, percentage-of-cost framework |
Note: Final bill text may change through committee deliberation and bicameral conference.
June 2026: Typhoon Season Has Started — What This Means for Your Structure
June 1 marks the official start of the Philippine Atlantic typhoon season. The heightened scrutiny of building safety following the Angeles City collapse intersects with a period of maximum structural weather loading. For any building currently under construction or recently completed, this is the time to verify two specific code requirements:
The National Structural Code of the Philippines requires all buildings to be designed for wind loads based on their location, height, exposure category, and occupancy. For the Philippines — a country that receives more typhoons per year than any other nation on Earth — this is not an optional provision. A building whose structural design does not include explicit NSCP 2015 §207 wind load analysis is operating in violation of the existing building code — and is at structural risk during every storm from June through November.
If you are currently in construction and your project does not have wind load calculations in the structural design documents — this must be corrected before the next significant weather event. A structure designed only for gravity loads can fail under typhoon conditions, even at design wind speeds well below a direct hit from a major cyclone.

How AEDO Ensures Compliance — Today and Under the Proposed New Act
Every project AEDO designs and builds already meets — and in several areas exceeds — the requirements proposed in HB 6615 and SB 2158. Not because of the legislation, but because structural integrity is the only defensible standard for licensed engineers.
- Structural design sealed by a licensed engineer covering full building height — We design for what you plan to build, not a reduced scope. Every floor, every rooftop load, every service installation is in the structural model before a column is cast.
- Explicit NSCP 2015 §207 and §208 compliance — Every project has documented wind and seismic load analysis with all parameters justified. Not referenced from a template — calculated from your specific site, zone, and soil conditions.
- Construction phase engineering supervision — Licensed engineers conduct and document on-site inspections at structural milestones. Rebar placement, column tie spacing, and concrete pour documentation are part of every AEDO project record.
- Materials documentation — Concrete cylinder test records and rebar mill certificates are standard on every AEDO project. This documentation is already in place for the requirements both bills propose.
- 3D structural modeling — Every AEDO project is modeled in 3D before construction begins. Load paths are visualized, seismic performance is analyzed, and structural drawings reflect the model — not the other way around.
- Permit compliance at every stage — Any scope change goes through formal re-analysis and OBO notification. No unauthorized additions, no permit violations, no regulatory exposure.
Get a Free Compliance Review — Know Your Risk Before the Inspector Does
If you have a project currently in construction or planning, now is the time for an independent compliance check. AEDO's licensed engineers will review your project against PD 1096 and NSCP 2015 requirements — at no cost for the initial consultation. We respond within 24 hours.

The Law Is Changing. The Standard Never Should Have Been Lower.
HB 6615 and SB 2158 are legislative responses to failures that existing law already prohibited — but failed to prevent. When the new building act passes, it will require what responsible engineering practice already demands: peer review, documented supervision, materials testing, and honest permit compliance. If your project already meets that standard, the new law changes nothing for you. If it doesn't — the time to fix it is before the next inspection, not after.
Frequently Asked Questions
The "New Philippine Building Act" refers to two related legislative proposals filed in Congress in May 2026: HB 6615 (House) and SB 2158 (Senate). Both seek to replace Presidential Decree 1096, the National Building Code of the Philippines signed in 1977. The bills were filed in direct response to the May 24, 2026 Angeles City building collapse and propose strengthened structural peer review requirements, modernized disaster resilience standards, and improved inter-agency enforcement coordination.
Yes. Presidential Decree 1096 signed in 1977 remains the primary building law as of June 2026. HB 6615 and SB 2158 are proposed replacements under Congressional deliberation — they have not been passed or signed into law. All current construction compliance obligations remain governed by PD 1096 and NSCP 2015. The post-collapse enforcement environment means these existing requirements are being applied more rigorously than before.
HB 6615's key additions over PD 1096 include: mandatory independent structural peer review by a second licensed engineer for buildings 5 storeys and above; scheduled construction-phase inspections at defined milestones; updated and substantially increased penalties for violations; mandatory materials certification requirements (concrete testing, rebar mill certificates); and stricter enforcement mechanisms for unauthorized floor additions — such as utility connection or occupancy permit denial until structural re-analysis is submitted and approved.
Under the existing National Building Code (PD 1096), any addition of floors or major structural loads beyond the approved permit requires a revised structural design and re-approval from the Office of the Building Official. The first step is to have a licensed structural engineer assess whether the original structural design can safely accommodate the actual built configuration — including any additions. If it cannot, retrofitting or structural remediation is required. Proactively addressing this now — before an agency inspection — is both the safer and the legally defensible path. Contact a licensed structural engineer for a confidential initial assessment.
The proposed bills' treatment of existing completed buildings has not been fully defined. Generally, Philippine building laws grandfather existing permitted structures but apply to renovations, changes of use, and vertical expansions. More immediately, the intensified enforcement environment following the collapse means OBO, DOLE, and DPWH inspectors are actively reviewing completed buildings — especially those with reported unauthorized modifications. Building owners who have concerns about their structure's compliance should conduct a proactive structural assessment rather than waiting for regulatory action.
Under NSCP 2015 Section 207, all Philippine buildings must be designed for wind loads based on their location, height, exposure category, and occupancy. Typhoon season runs June through November — and peak activity months of August through October bring design-level wind events annually. Any building whose structural design does not include explicit wind load analysis per §207 is both non-compliant with existing law and at structural risk during the current season. If your project lacks documented wind load calculations, a licensed structural engineer should review the design before the next significant weather event.
