The average cost to build and install a semi-inground pool in Washington, DC, is $13,068, with most homeowners spending between $7,623 and $21,780 on typical projects. Material choice and pool size largely affect how much you can expect to pay. The District's small lot sizes, historic districts, and humid summers all shape your final project cost, too.
Semi-Inground Pool Cost Factors
Semi-inground pool projects in Washington, DC, must consider the region's small, tightly zoned lots and historic preservation rules. Semi-inground pools may use in-ground or above-ground pools for different components. Fully custom concrete pools generally fall into a higher price category.
Size
Unsurprisingly, different pool sizes relate to different price ranges. The larger your semi-inground pool, the higher the cost. Prices range from $18,000 for a 10-foot-diameter pool to $55,000 or more for a 24-foot-diameter pool. Standard pools in prefabricated shapes will cost less than custom installations with excavation, decking, or difficult access, which cost more. Larger custom pools may exceed the typical cost range.
Here’s how your semi-inground pool cost will vary based on size:
| Size (Feet) | Average Cost |
|---|---|
| 10 | $18,000 |
| 12 | $22,000 |
| 16 | $30,000 |
| 20 | $40,000 |
| 22 | $45,000 |
| 24 | $55,000 |
Angi Tip
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.
Materials
In terms of what to consider when putting in a pool, material choice tops the list, from $18,000 for steel to $60,000 for concrete. Fiberglass is a popular option in the District thanks to its faster install time on small urban lots, while concrete pool types remain the top choice for homeowners who want full customization and don't mind the longer construction timeline.
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 | $18,000 | Aboveground |
| Steel | $18,000 | Aboveground |
Historic District and Zoning Review
Some homes in DC's historic districts may require additional design review if proposed work affects protected exterior features or is visible from a public street. This includes many neighborhoods across the District, such as Georgetown, Capitol Hill, and Dupont Circle. Check with the DC Historic Preservation Office before finalizing your plans if you're unsure whether your property is affected.
Pool Pro Costs
The cost of labor to hire local pool contractors in Washington, DC, is a significant line item when estimating your budget for installing a semi-inground pool here. Permits and additional trades further contribute to project costs.
Labor
Labor makes up 25% to 50% of your total project cost when building a semi-inground pool in Washington, DC. Most pool contractors in the District charge between $55 and $150 per hour, totaling an estimated $10,000 to $25,000 or more in labor for a standard semi-inground build.
Permits and Licensing
Building permit fees are based on construction value, with separate permits often required for electrical and plumbing work. Total permit costs run from several hundred to more than $1,500, depending on project valuation, required reviews, and trade permits. Contractors performing pool work in Washington, DC, must meet applicable District licensing requirements, and electrical and plumbing work must generally be completed by appropriately licensed tradespeople.
Additional Pros to Consider Hiring
Beyond your pool installer, you'll likely need a licensed electrician at $50 to $100 per hour to install and connect the pool pump, lighting, heater, bonding, and other electrical components. A plumber charges $45 to $200 per hour to install circulation piping, water supply connections, and pool equipment plumbing.
Does a Semi-Inground Pool Increase Home Value?
Pools may improve buyer appeal for some single-family homes in Washington, DC, but the financial return on investment (ROI) varies widely depending on neighborhood, lot size, and buyer preferences. The District's hot, humid summers support solid pool use, though cold winters and a relatively short season are worth weighing against the pool ROI you might see in warmer, year-round climates.
How Angi Gets Its Local Cost Data
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.
