In-Ground Pool Cost Factors

Building an in-ground pool is an investment, but one that can increase your satisfaction with your home as well as your home’s value. Before you start the project, it’s important to look at the different cost factors that will ultimately make up the total cost of an in-ground pool in Washington, D.C.

Pool Type and Materials

There are three main types of pools to choose from when you’re planning an in-ground pool project. Each material comes with its own pros and cons. Washington, D.C. is a good candidate for all of these materials.

• Vinyl: Vinyl pools are often more budget-friendly than fiberglass or concrete. The vinyl liner will need to be replaced about every 10 years, which can add to long-term maintenance costs but will extend the pool’s life if done properly.  

• Fiberglass: Fiberglass pools aren’t as customizable as concrete because they are prefabricated. But this also means they aren’t as expensive and they’re easier to install.

• Concrete: Concrete is highly customizable as it can be poured to create any shape. It can be further customized with tile, polished aggregate, or plaster. It is, however, the most expensive pool type.  

Size

Size is one of the major factors in determining the final cost of the project. Pool costs range from $90 to $150 per square foot to install, and you can use this range to get an estimated cost range for your in-ground pool. Check out the table below to see cost ranges for various popular pool sizes. If you want to build a custom pool, you can ask your contractor how different in-ground pool shapes will affect the cost. 

Additional Costs

Adding an in-ground pool comes with additional costs to cover site prep, lighting, fencing, and other necessities, but you may also want to include features like a slide or hot tub to make pool days even more fun. 

• Pool lighting: $200 per light

• Solar pool cover: $75–$300

• Hot tub: $5,000–$20,000

• Slide: $1,500–$20,000

• Landscaping: $700–$3,300

• Pool fence: $1,500–$10,000

• Site prep: $500–$3,020

• Yearly pool maintenance cost: $120–$5,000

Climate

Though the average low for January is 30 degrees Fahrenheit, it can often get much colder throughout the winter months, dipping down into the 20s or slightly lower. Temperatures in the summer reach an average of 88 degrees Fahrenheit, with highs into the mid- to upper-90s. The hot season lasts from May to September, giving you lots of time to enjoy a pool, but you’ll have to close it in the winter to prevent any cold-weather damage. 

In-Ground Pool Pro Costs

In-ground pool costs go beyond purchasing the materials. You’ll also need to factor in labor costs, building requirements, and permit costs as well as how the in-ground pool installation will affect your home value and, ultimately, your property taxes. 

Building Code Requirements

Your local in-ground pool company will be familiar with building code and safety requirements, which may include fencing requirements, pool alarms, gates and latches guidelines, and more. 

Permits and Inspections

The District of Columbia requires a swimming pool permit for the construction of a swimming pool, and you may need separate permits for water system installation. Your local contractor will know exactly how to obtain the correct permits as well as how to order any required inspections.

Labor

Installing a pool requires a significant amount of labor, and labor costs make up between 25% and 50% of the total cost to install an in-ground pool. If the contractor calculates the labor hourly, you can expect to pay between $55 and $150 per hour. When you get your estimate, make sure labor costs are included and that you know how they’re calculated.

Property Taxes

The real property tax rates in Washington, D.C. are calculated based on the property’s classification. Residential properties are taxed at a rate of $0.85 per $100 of the property’s assessed value up to $2.5 million. The rate increases to $1 per $100 for residential properties with no more than two dwelling units that have an assessed value higher than $2.5 million. Because a pool will increase home value, you can expect your property taxes to go up once the pool is installed and the property is assessed. 

Does an In-Ground Pool Increase Home Value?

Nationwide, pools typically increase home value and offer a return on investment between 5% and 56%. In Washington, D.C., an in-ground pool can add between 10% and 15% to your home’s value. Because the winters are cold, you may not get as great of a value increase as you would in climates that are warmer year-round.
