Understanding the Two Permit Paths
When you need a building permit in Los Angeles, your project will follow one of two paths: express permit processing (approximately 5 business days) or regular plan check review (approximately 3 months). Understanding the difference is critical to planning your project timeline and budget.
Express Permits: The Fast Track (5 Days)
Express permits are designed for routine, non-structural work that doesn't require a formal plan review. Key characteristics include:
- No plan check required � applications are reviewed at the counter
- Approved within approximately 5 business days
- Lower fees compared to plan check permits
- Suitable for replacements, repairs, and minor modifications
- Must meet the same size/type rule and the 10% rule
Regular Plan Check Permits: The Standard Route (~3 Months)
Regular plan check permits are required for more complex projects. They involve:
- Formal plan submission with architectural drawings
- Review by LADBS plan check engineers (typically 2-3 months)
- Multiple review cycles if corrections are needed
- Higher fees including plan check fees
- Required for structural work, additions, and new construction
The Timeline Difference
The most significant difference is time. An express permit takes about 5 business days. A regular permit takes approximately 3 months. That's a difference of nearly 12 weeks � which can translate to thousands of dollars in project delays.
How to Determine Which You Need
The key factors that determine your permit type are:
- Structural impact: Any work affecting load-bearing elements requires plan check (~3 months)
- Scope of work: Replacements and repairs often qualify for express (5 days); new installations may not
- The 10% rule: Modifications exceeding 10% of existing systems require plan check
- Same size/type: Replacements must match the original to qualify for express
