What to know before you ever talk to a builder. The decisions you make before the first meeting will determine how smoothly your entire project goes.
- Pull your property survey before anything else — it is one of the most important documents you own
- Setbacks and easements are measured from property lines — not your fence
- Most Texas cities require a pool to sit at least 3 feet from any property line
- Utility easements cannot be built upon — not the pool, not the deck, not the equipment pad
- Drainage easements — same rule. No permanent structures allowed within them
- If you cannot find your survey, contact your county clerk or title company
Utility easements are legally reserved for underground infrastructure — gas, electrical, cable, water, drainage. If a utility company needs to access an easement, they are not obligated to repair or replace anything they damage — including a pool built inside one. Typical rear utility easements in Texas run 7 to 14 feet along the back property line. Your fence may not be placed exactly on the property line, so never use the fence as your measurement reference.
- Lay out a garden hose in your desired pool size and shape — live with it for a few days
- Look at it from inside the house, from the patio, and from the back of the yard
- Decide which side of the yard you want the pool equipment on — pump, filter, heater, chiller
- Note where your gas meter or propane tank is located
- Note where your electrical panel is located
- Measure your side yard access — 6 feet or more is needed to get construction equipment to the backyard
- Know where your irrigation system runs — those lines will need to be rerouted
If your gas service is on the opposite side of the house from your intended equipment pad, running a new gas line around the structure can add thousands of dollars to your project. The same applies to electrical. A thorough builder will ask about both of these upfront. If they don’t, that is a red flag.
A knowledgeable builder will raise every one of these. If they don’t, consider it a warning sign.
- Overhead power lines near the build zone
- Septic tanks, drain fields, and aerobic systems — extremely common in Hill Country and rural Austin builds
- Soil conditions — Central Texas clay soils shift with moisture and affect pool engineering
- Large trees and root systems near the pool location (see CRZ below)
- Existing irrigation lines running through the build zone
- Drainage — where does water go when the pool overflows or when it rains heavily?
A pool must maintain a minimum 5-foot setback from a septic tank and drain field. Aerobic systems are more complex — in many Texas areas the drain field cannot be within 25 feet of the pool, and aerobic sprinkler heads must be at least 50 feet from the pool. Texas regulates on-site sewage facilities under 30 TAC Chapter 285 through the TCEQ. Always confirm with your local permitting authority as local rules may be more restrictive.
Central Texas is well known for expansive clay soils that shift and move with moisture changes. This directly affects how your pool shell is engineered and may require additional structural steel. A builder who never mentions soil conditions in Central Texas hasn’t built enough pools in the region.
Large live oaks and cedar trees near your pool location are a hidden cost that surprises many homeowners. The CRZ contains most of the roots vital to a tree’s health and survival. If construction invades too far into the CRZ, the tree may not recover. If 30 percent of a tree’s CRZ is impacted, it could be deemed beyond probable recovery.
Measure the trunk circumference at 4 feet above the ground. Divide by 3.14 to get the diameter in inches. Multiply the diameter by 1.5 — this gives you the CRZ radius in feet. A trunk with a 45-inch circumference has a CRZ radius of approximately 22 feet in every direction.
Most of a tree’s roots are within the top 18 inches of soil, and 85% of the root mass sits within the CRZ. Pool shell excavation, equipment pad grading, and plumbing trenches can all cause irreversible damage if they cross into this zone. Removal of significant trees may also require a permit in Austin and many Hill Country municipalities.
- Your builder should handle all permitting — you should not be doing this yourself
- After the permit is filed, verify it directly with your city’s building department — don’t take anyone’s word for it
- Confirm the permit number is active before any ground is broken
- Unpermitted pools create serious problems at resale and can require costly retrofits or demolition
- Texas requires a barrier around all pools deeper than 24 inches — this is not optional
- Fences must be at least 48 inches tall, measured from the outside of the pool area
- Chain-link fencing is prohibited for pools built after 1994
- No gaps may exceed 4 inches — gates must be self-closing, self-latching, and swing inward away from the pool
- Budget for fencing early — it is part of the total project cost and a condition of final inspection
- Many HOAs require architectural committee approval before construction begins
- HOAs can have additional setback requirements, aesthetic standards, and fencing rules beyond city code
- This approval process can take weeks — start it early
- Get all HOA approval in writing before signing a pool contract
- There is no dedicated state license required to start a pool construction company in Texas
- The barrier to entry is very low — quality varies widely across the market
- The cheapest bid is rarely the best value
- Incomplete projects, abandoned contracts, and poor workmanship are real and recurring problems in Texas
What IS regulated: Standard pool plumbing does not require a plumber’s license in Texas, though some cities require a licensed plumber on the permit — verify locally. Gas line work must be performed by a licensed plumber. RPZ (backflow prevention) valves must be installed by someone with a valid backflow prevention certification. Electrical work on pool equipment requires a Residential Appliance Installer License (RAIL) from TDLR. Irrigation contractors must hold a TDLR license. You can verify any TDLR license at tdlr.texas.gov.
- The small chip samples your builder hands you do not show you what your pool will look like
- Your tanning ledge, top step, and bench will always appear significantly lighter than the deep end — same plaster, different depth — this is normal
- Pool color is affected by your house color, surrounding trees, sky conditions, and water chemistry
- For water that looks primarily blue, select a finish with white, blue, or gray pigment
- For water that appears green or aqua, look for green, tan, brown, or black pigment
- The darker your finish, the darker your pool water will be
Living Water & Plaster Colors: One of the most underappreciated elements in pool design is what happens to plaster color when the water moves. Still water shows your plaster one way. Active water — from sheers, bubblers, deck jets, or waterfalls — creates constant refraction that makes the color shift, shimmer, and dance in ways a static pool never can. The same plaster you chose from a chip sample will look entirely different, and far more beautiful, when the water is in motion. When selecting plaster colors, ask your builder to show you video or photos of that finish in pools with active water features — because that is what your pool will actually look like. See the Water Features section for more on living water design.
