Understanding LA Permit Timelines
The number one question I get after 'how much does it cost?' is 'how long does it take?' And in Los Angeles, the honest answer is: it depends on where you live and what you're building. Let me break down realistic timelines so you can plan accordingly.
Standard Permit Timelines (Flat Lots)
For properties on flat lots in standard residential zones:
- Pool permit: 4-8 weeks plan check, then permit issuance
- Hardscape/patio permit: Often not required, or 2-4 weeks
- Covered patio under 200 sq ft: 2-4 weeks (exempt in some cases)
- Outdoor kitchen with utilities: 4-8 weeks (multiple departments)
- Retaining wall under 4 feet: Often exempt from permit
These timelines assume clean submittals that don't require corrections. First-time corrections add 2-4 weeks each round.
Hillside Permit Timelines
Properties in designated hillside areas face significantly longer timelines:
- Pool permit: 6-12+ months (multiple department reviews)
- Significant grading: 6-12 months
- Retaining walls: 4-8 months
- Any structural work: 6-12+ months
Hillside projects require reviews by Building & Safety, Grading, Bureau of Engineering, and sometimes Planning. Each department has its own queue and requirements.
💡 Pro Tip
If you're on a hillside property, start the permit process immediately. Some clients wait until spring to start planning a summer pool—that's too late. You need to start 12-18 months before you want to swim.
What Affects Permit Speed
Factors That Slow Things Down
- Hillside zone (additional departments review)
- Historic district (HPOZ review required)
- Zoning variances needed
- Incomplete or incorrect submittals
- Complex engineering requirements
- Properties near fault lines or fire zones
Factors That Speed Things Up
- Flat lot in standard zone
- Complete submittals with all requirements
- Experienced permit expediter
- Express plan check (additional fees)
- No corrections required
LADBS Express Service
LADBS offers express plan check for additional fees. This can reduce standard timelines by 50-75%. For pools, express service typically costs $1,500-$3,000 extra but can save months of waiting.
Express isn't available for all project types, and hillside projects often can't use it because multiple departments are involved.
