The cost to build a semi-inground pool in Los Angeles, CA, averages $13,632, with most homeowners paying between $7,952 and $22,720 on typical installation projects. Southern California's near-year-round swim season and dense hillside neighborhoods both shape your final price, so understanding your yard's terrain and access before you budget will help you avoid mid-project surprises.
Building a semi-inground pool in Los Angeles, CA, comes with cost considerations you won't find in flatter, cheaper markets, from grading rules on hillside lots to site access and engineering needs. Semi-inground pools may use inground and above-ground pool materials, with the former installed with partial exposure and the latter partially buried into the landscape.
Different pool sizes come at different cost levels. Prices range from $15,000 for a 10-foot-diameter pool up to $65,000 or more for a 24-foot-diameter pool. Standard pools in prefabricated shapes will cost less than those with custom measurements. Most semi-inground pools are between three and eight feet deep, depending on your preference.
Here’s how your semi-inground pool cost will vary based on size:
| Size (Feet) | Average Cost |
|---|---|
| 10 | $15,000 |
| 12 | $20,000 |
| 16 | $30,000 |
| 20 | $45,000 |
| 22 | $55,000 |
| 24 | $65,000 |
No time to maintain your pool? Most pool contractors offer seasonal maintenance. Talk to your pro about scheduling check-ups to keep your pool healthy.
Material choice affects your semi-inground pool cost significantly in Los Angeles, CA, ranging from an average of $15,000 for steel to $60,000 for concrete. Concrete pools remain popular here because they allow custom designs and work well for complex landscapes, while fiberglass pool types can offer faster installation and lower maintenance.
Here’s how your semi-inground pool material might affect the cost:
| Pool Material | Average Cost | Best For |
|---|---|---|
| Concrete | $60,000 | In-ground |
| Fiberglass | $45,000 | In-ground |
| Vinyl (liner) | $35,000 | In-ground |
| Aluminum | $20,000 | Aboveground |
| Resin | $15,000 | Aboveground |
| Steel | $15,000 | Aboveground |
When it comes to what to consider when putting in a pool, the terrain of your property is a significant factor. Many backyards across Greater Los Angeles, CA, sit on sloped lots. A hillside semi-inground pool can add $5,000 to $25,000 or more for grading, retaining walls, drainage improvements, or crane access. Narrow side yards or homes without rear access may also require hand excavation, adding to your labor bill.
Beyond materials, homeowners should budget for labor from Los Angeles, CA, pool installers, permitting, and the region's higher cost of living. These all push semi-inground pool installation here above the national average.
Professional labor can account for 30% to 50% of the project cost. A semi-inground pool installation may include $10,000 to $30,000 or more in labor, depending on excavation, access, and site complexity.
Permitting is more involved in Los Angeles, CA, than in many other cities. Combination building, electrical, and plumbing permits run $500 to $2,500. Hillside properties may also need a basic soils or geotechnical report for $1,500 to $5,000, plus hillside engineering and design for an extra $5,000 to $15,000 or more.
Beyond your local pool installer, you may need a licensed electrician for pump wiring and lighting, as well as a licensed plumber to run water lines. A pool builder in Los Angeles, CA, can usually coordinate these subcontractors for you as part of your overall project.
A pool can improve buyer appeal in Los Angeles, CA's warm climate, but homeowners should not expect to recover the full installation cost. Some estimates place the return on investment (ROI) at around 40% to 65%, but actual results vary widely depending on neighborhood, pool quality, and buyer preferences. Pool ROI should consider not only project cost recovery, but also improved quality of life and buyer appeal.
To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.
Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
