Construction is not only about gathering bricks with a paste of cement and sand, it’s about building spaces where humans are born, grow, work, succeed, and form a community. In Los Angeles, where architectural variety and safety measures are critical, understanding the different types of construction is crucial. In 2023, Los Angeles’ construction industry was valued at approximately $11.5 billion, making it one of the largest markets in the United States.
Whether designing high-rise commercial buildings or crafting cozy residential homes, choosing the right construction type ensures durability, safety, and cost-efficiency. This blog will explore the most common types of construction, with insights to help you make well-informed decisions for your next project.
What Are the Most Common Types of Construction?
Every building is unique, but construction types can be broadly categorized based on materials, fire resistance, and structural design. Knowing these categories not only ensures compliance with building codes but also influences project costs, timelines, and safety features.

Type I: Fire-Resistive Construction – A Common Choice for High-Rise Buildings
Type I buildings are known for their high fire resistance. They typically use non-combustible materials like concrete and steel. These structures can withstand extreme temperatures for extended periods, making them ideal for high-rise buildings, hospitals, and large commercial spaces.
- Exceptional fire resistance and structural durability are considered its strengths. It has high construction costs and extended building timelines due to heavy materials. It’s more suitable for high-rise residential buildings, commercial skyscrapers, and hospitals.
- Guiding the complex building codes for high-rise structures in Los Angeles requires meticulous planning. From obtaining permits to coordinating with engineers, every detail matters, especially when safety is a top priority.
Type II: Non-Combustible Construction – A Practical Solution for Commercial Projects
Type II construction uses similar materials to Type I but with less stringent fire resistance requirements. It combines non-combustible materials like steel and concrete with cost-effective designs, making it a practical choice for many commercial buildings.
- It is good fire-resistant, and more cost-effective than Type I, while its materials can weaken under extreme temperatures.
- It’s the best choice for commercial buildings, newer schools, and industrial structures.
In Los Angeles, this construction type is commonly seen in modern educational facilities and shopping centers. The ability to balance safety and cost makes it a popular choice for mid-sized commercial projects.
Type III: Ordinary Construction – Balancing Flexibility and Cost-Efficiency
This type features non-combustible exterior walls paired with combustible interior components, like wood framing. It strikes a balance between fire resistance and cost-efficiency, offering design flexibility.
- Cost-effectiveness with design flexibility is its positive point, while its interior wooden framing is more susceptible to fire.
- Type 3 is the best choice for older schools, mixed-use buildings, and residential complexes.
From remodeling older brick buildings to constructing new mixed-use spaces, Type III construction is a common sight in the bustling neighborhoods of Los Angeles, blending tradition with modern needs.
Type IV: Heavy Timber Construction – Combining Aesthetic Appeal with Structural Strength
Also known as “mill construction,” this type uses large wooden components that provide structural strength and natural fire resistance. The massive timber members char on the outside, creating a protective layer that maintains their structural integrity.
- High structural strength and natural fire resistance are its strengths, on the other hand, it requires skilled labor and has higher material costs which is mentioned as its weakness.
- For historic warehouses, modern eco-friendly designs, and churches this type of construction is best.
Combining heavy timber in contemporary designs provides a unique aesthetic appeal, which resonates well with Los Angeles’s blend of tradition and modernity. It’s particularly popular in eco-conscious neighborhoods.
Type V: Wood-Framed Construction – The Most Common Residential Construction Type
The most common type of residential construction, Type V uses wood framing for walls, floors, and roofs. Its cost-effectiveness and ease of construction make it the go-to choice for single-family homes and small apartment buildings.
- Its design options are cost-effective, flexible, and easy to construct. It has low fire resistance and vulnerability to termites.
- For single-family homes, townhouses, and small apartment complexes wood-framed construction is a matchless option.
Particularly in Los Angeles, this type of construction dominates the residential landscape, providing affordable housing solutions that maintain aesthetic appeal and functional design. From hillside homes to urban townhouses, this type caters to various lifestyle needs.
Why Understanding the Most Common Types of Construction Matters
- Compliance with Building Codes: Each construction type must stick to specific building codes and regulations, ensuring legal compliance.
- Safety and Functionality: The construction type impacts the building’s resistance to fire, earthquakes, and other hazards. Proper selection enhances occupant safety by minimizing risks associated with structural failures or fire spread.
- Seismic and Fire Safety in Los Angeles: Los Angeles has a high tendency of earthquakes and wildfires, making construction type a critical factor in building resilience. Using fire-resistant materials and earthquake-resistant designs reduces damage and enhances occupant safety.
- Impact on Project Success: The right construction type optimizes functionality, cost-efficiency, and long-term maintenance. It influences design choices, project timelines, and overall project feasibility.
