highway may project not more than 300 millimeters beyond the property line.

(c) Foundations may be permitted to encroach into public sidewalk areas to a width not

exceeding 500 millimeters; provided, that the top of the said foundations is not less than

Section 1005. Canopies (Marquees).

(a) Definition. A canopy or marquee is a permanent roofed structure above a door

attached to and supported by the building and projecting over a wall or sidewalk. This

includes any object or decoration attached thereto.

the marquee and the carb line shall be not less than 300 millimeters. The vertical

clearance between the pavement or ground line and the under surface of any part of the

marquee shall not be less than 3.00 meters.

(c) Construction. A marquee shall be constructed of incombustible material or materials

of not less than two-hours fire-resistive construction. It shall be provided with necessary

drainage facility.
(d) Location. Every marquee shall be so located as not to interfere with the operation of

from the building or the installation or maintenance of electroliers.

Section 1006. Movable Awnings or Hoods.

(a) Definition. An awning is a movable shelter supported entirely from the exterior wall

of a building and of a type which can be retracted, folded, or collapsed against the face

of a supporting building.

(b) Clearance. The horizontal clearance between the awning and the curb line shall not

be less than 300 millimeters. The vertical clearance between the undermost surface of

the awning and the pavement or ground line shall be not less than 2.40 meters.

Collapsible awnings shall be so designated that they shall not block a required exit

when collapsed or folded.

Section 1007. Doors, Windows, and the like.

Doors, windows and the like less than 2.40 meters above the pavement or ground line

shall not, when fully opened or upon opening, project beyond the property line except

fire exit doors.

Section 1008. Corner Buildings with Chaflans.

(a) Every corner building or solid fence on a public street or alley less than 3.60 meter in

width shall be truncated at the corner. The face of the triangle so formed shall be at

right angles to the bisector of the angle of the intersection of the street lines; provided,

that in no case, the Secretary shall determine the size and form of the chaflan.
(b) If the building is arcaded, no chaflan is required notwithstanding the width of the

public street or alley, less than 12.00 meters.

Chapter 10 of the National Building Code of the Philippines covers "Light and Ventilation." This
chapter is essential for ensuring that buildings provide adequate lighting and ventilation for the
occupants' comfort, health, and safety. Here's a general overview of the key points covered in
this chapter:
​ Purpose and Scope:
● The purpose of Chapter 10 is to establish standards for the minimum amount of
natural light and ventilation that buildings should provide.
● The chapter covers various types of buildings, including residential, commercial,
industrial, and institutional structures.
​ Natural Light Requirements:
● The chapter specifies the minimum amount of natural light that different types of
spaces within a building must receive.
● It outlines factors such as the size of windows, clear opening areas, and the
distance between the windows and the interior spaces.
​ Natural Ventilation Requirements:
● The chapter sets standards for the minimum amount of fresh air circulation that
different types of spaces should have.
● It addresses factors like the size and location of openings, cross-ventilation, and
the provision of air vents.
​ Light and Ventilation for Specific Spaces:
● The chapter provides detailed requirements for various types of rooms, including
bedrooms, living rooms, kitchens, bathrooms, and more.
● It outlines the specific dimensions of openings, such as windows and vents, that
are necessary to ensure proper lighting and ventilation for these spaces.
​ Exemptions and Special Situations:
● The chapter may outline exemptions for certain spaces or situations where
natural lighting and ventilation standards might not be met due to specific design
constraints.
● It might also provide guidelines for alternative methods of achieving adequate
lighting and ventilation.
​ Design Considerations:
● The chapter emphasizes the importance of designing buildings that optimize
natural light and ventilation while taking into account factors like building
orientation, shading devices, and energy efficiency.
​ Enforcement and Compliance:
● The chapter may include provisions for inspection, compliance checks, and
penalties for buildings that do not meet the prescribed standards for light and
ventilation.
​ Integration with Other Chapters:
● Light and ventilation requirements are interconnected with other chapters of the
National Building Code, such as those related to fire safety, structural design, and
occupancy classifications.
