Building codes are standards and regulations that define the design, construction, and use of buildings in a specific jurisdiction. In the Philippines, building codes are under the jurisdiction of the Department of Public Works and Highways (DPWH) and the Housing and Land Use Regulatory Board (HLURB).
The Building Code of the Philippines, also known as the National Building Code of the Philippines (NBCP), outlines the minimum standards for the design and construction of buildings, including requirements for site development, building design, fire and life safety, elevators and escalators, plumbing and drainage systems, among others.
In addition to the NBCP, several other codes apply to specific aspects of building construction, including the Earthquake-Resistant Design and Construction of Buildings Code, Fire Code of the Philippines, Plumbing Code of the Philippines, and Electrical Code of the Philippines.
These codes ensure that buildings are safe, durable, and compliant with national standards and regulations and serve as a guide for building designers, contractors, and local government authorities. Adherence to building codes is mandatory for all construction projects in the Philippines, and failure to comply can result in penalties, fines, or demolition.

Significance of implementing the Building Code of the Philippines
The primary goal of the Building Code is to ensure the safety of buildings and their occupants. Following the code’s guidelines, buildings are designed and constructed to withstand natural disasters such as earthquakes, typhoons, and floods, which are not uncommon occurrences in the Philippines. It also ensures that buildings are structurally sound and safe for human occupancy.
The Building Code also sets standards for ventilation, lighting, and sanitation, which promote good health and hygiene in buildings. It ensures that structures are equipped with adequate drainage and sewage systems to prevent the spread of diseases.
The Building Code promotes sustainable development by requiring the use of eco-friendly building materials and technologies. It also mandates incorporating energy-efficient features, such as insulation and renewable energy sources, which reduce the environmental impact of buildings.
The Building Code is a legal requirement for anyone involved in the design, construction, or occupancy of buildings in the Philippines. Compliance with the code is necessary to obtain building permits and occupancy permits. Non-compliance may result in penalties, fines, and legal liabilities.
Implementing the Building Code promotes economic growth by ensuring the safety and reliability of buildings. Safe and durable buildings attract more investors, which leads to the creation of jobs and economic opportunities.
The history and development of the Building Code of the Philippines date back to the Spanish colonial period when the country adopted the Spanish Code of 1884. In 1936, the Commonwealth of the Philippines enacted its building code based on the 1935 National Building Code of the United States.
In 1972, President Ferdinand Marcos issued Presidential Decree No. 1096, the National Building Code of the Philippines (NBCP). The NBCP was a comprehensive law that aimed to regulate the design, construction, and occupancy of buildings in the country. The NBCP also created the National Building Code Development Office (NBCDO), which was responsible for the administration and enforcement of the code.
The NBCP was amended several times, including in 2004, when the Philippine Green Building Code was adopted. The Green Building Code aimed to promote environmentally sustainable buildings and encourage using energy-efficient materials and technologies.
In 2010, the NBCDO was dissolved, and its functions were transferred to the Department of Public Works and Highways (DPWH). The DPWH was tasked with the enforcement of the NBCP and the issuance of building permits and occupancy permits.
In 2016, the DPWH revised the NBCP to update its provisions and align them with international standards. The revised NBCP included new provisions for disaster-resilient buildings, accessibility standards for persons with disabilities, and the use of green technologies.
In 2018, the DPWH issued a memorandum circular requiring all new buildings in the country to comply with the 2017 National Structural Code of the Philippines. The new code aimed to improve the safety and resilience of buildings in the country by introducing new design and engineering standards.
Today, the Building Code of the Philippines continues to evolve to keep up with the changing needs of the construction industry and promote safety, sustainability, and economic growth.

What is a building permit
A building permit is a formal authorization issued by a government agency, usually a local building department, allowing a person or company to start construction or make alterations to a building. The purpose of a building permit is to ensure that the construction or alteration work meets minimum safety, health, and environmental standards set by the building code, and to ensure that the construction or alteration work is consistent with the approved plans and specifications.
Building permits are typically required for new construction projects, additions, renovations, and other types of alterations to existing buildings and usually involve a review of plans, specifications, and other relevant documents, as well as inspections of the work during and after construction to ensure compliance with the building code.
In addition to ensuring compliance with building codes, building permits are often required for insurance purposes and to avoid potential legal issues related to construction and property ownership.
Requirements for building permit application
To receive a building permit, the applicant must submit to the building official’s office a written application along with the following requirement:
- A detailed work description to be covered by the requested permission;
- A copy of the transfer certificate of title (TCT) of the parcel of land where the building work will be carried out;
- A copy of the lease contract (suppose the applicant is not the registered owner)
- The planned use or occupancy for the proposed work;
- The proposed work’s estimated cost
Process of building permit application
The process for applying for a building permit can vary slightly depending on the jurisdiction but typically involves the following steps:
Obtain plans and specifications
Before applying for a building permit, you must have detailed plans and specifications for the construction or alteration work. These plans should be prepared by an architect or engineer and should include all relevant details about the project, such as the size and location of the building, the type of construction, and the materials to be used.
Complete permit application
Once you have your plans and specifications, you must complete a permit application form, usually available from the local building department. The application form typically asks for information about the proposed project, including the location, size, and type of construction, as well as the owner and contractor information.
Submit plans and application
Along with the completed application form, you must submit the plans, specifications, and other relevant documents, such as site plans, structural calculations, and energy efficiency reports.
Pay permit fees
Most building departments charge fees for building permits, which may be based on the size and complexity of the project. You will need to pay these fees when you submit your application.
Review and approval
After you submit your permit application, the building department will review it to ensure that it meets all applicable building codes and standards. Depending on the project’s complexity, this review process can take several weeks or even months.
Inspection and approval
Once the building permit is approved, you can start construction. Still, the work must be inspected regularly to ensure that it complies with the building code and the approved plans and specifications.
Final inspection and approval
Once the construction work is complete, a final inspection is typically conducted to ensure that the work meets all building code requirements. If the work is approved, the building permit is closed, and the building can be occupied.
Rejection of application or revocation of building permit
A building permit can be denied if the building department determines that the proposed construction or alteration work does not meet the minimum safety, health, and environmental standards set by the building code. For example, if the plans and specifications submitted with the permit application do not meet the required building code standards, the building department may deny the permit.
A building permit can also be revoked if the construction work is not carried out under the approved plans and specifications or does not comply with the building code. For example, if the work is not completed within the specified time frame or is not inspected and approved by the building department, the building permit may be revoked.
In addition, a building permit can be revoked if the construction work is not done following the approved plans and specifications or if the work does not comply with the building code. For example, the building department may revoke the permit if the work is not done in a safe and timely manner or if the work is not done following the approved plans and specifications.
In some cases, a building permit can be revoked for other reasons, such as failure to pay fees or for violation of zoning regulations. It is important to follow all building code and zoning regulations to avoid having a building permit denied or revoked.
