Los Angeles Construction Cost per Square Foot
Building in Los Angeles is notoriously expensive due to land scarcity, seismic requirements and high material costs. According to GreatBuildz, the average cost to build a house in Los Angeles ranges from $300 to over $800 per square foot, with most projects falling between $400 and $500 per square foot.
Costs vary widely based on site conditions, architectural complexity and interior finishes. Building on a hillside lot, for example, requires extensive grading and retaining walls and can dramatically increase expenses.
Homeowners planning a custom home should budget for hard costs (materials and labor), architectural fees and soft costs such as permits, inspections and insurance.
Commercial construction costs also fluctuate by project type. LA ranks among the most expensive U.S. cities for office and hospitality projects, and institutional buildings such as hospitals and labs often exceed $1,000 per square foot due to specialized systems.
Contractors like Swinerton, Turner and DPR Construction provide detailed cost estimates during preconstruction to help clients plan budgets.
Choosing the Right Construction Company in Los Angeles
Selecting the best contractor for your project requires careful research. Here are a few tips:
- Define your project type and scope. General contractors such as Tutor Perini and Turner handle major civic and commercial projects, while firms like Alpha Structural focus on specialized services like foundation repair. Match your project requirements with a company’s expertise.
- Review past projects and references. Look for firms with a proven track record in LA, including successful completion of similar projects. Many top contractors list recent projects and client testimonials on their websites or in industry rankings.
- Verify licensing and insurance. California requires contractors to hold appropriate licenses and carry workers’ compensation and liability coverage. Check the California Contractors State License Board (CSLB) database before signing a contract.
- Assess sustainability and innovation. Leading firms are adopting sustainable practices and digital tools to reduce waste and improve efficiency. For example, Swinerton has been recognized for safety excellence and innovation, while DPR Construction specializes in prefabrication and virtual design services.
- Consider company culture and communication. Employee‑owned firms like Swinerton and PCL often prioritize collaborative project delivery and may offer more personal engagement. Meeting with the project team upfront can reveal how well they communicate and whether they prioritize client goals.
