You’ve got your dream floor plan. You’ve picked the perfect lot. You’re ready to build! Then… the bills start rolling in, and suddenly your “fixed” budget isn’t looking so fixed.

Here’s the truth: Even the best new-construction builds have hidden costs. But with the right prep (and a builder who’s transparent from the start), you can stay in control.

Let’s break down seven expenses Tulsa buyers are often surprised by — and how to plan for them.

‍

Utility Tap Fees and Connection Costs

Before you can enjoy water, sewer, or electricity, you’ve got to connect to the city or rural system — and that’s not free.

• Water/Sewer Tap Fees: In Tulsa city limits, expect around $2,000–$3,500 combined depending on meter size and service line. In Bixby or Broken Arrow, it can range higher, especially for larger lots or new subdivisions.
• Electric Setup: If your property needs new service poles or trenching, PSO (Public Service Company of Oklahoma) may charge for installation.
• Gas Hookup: ONG (Oklahoma Natural Gas) will often install lines for free within standard limits — but long runs or rural builds can cost thousands.

Budget tip: Ask your builder early who pays for each utility tap and whether it’s included in your contract price.

‍

Soil Testing and Foundation Adjustments

Tulsa County soil is famous for its expansive clay, which swells when wet and shrinks when dry. It’s one of the biggest culprits behind cracked driveways or shifting slabs.

• A geotechnical soil report runs about $1,000–$3,500 but can save you tens of thousands in future repairs.

Budget tip: Never skip the soil report. It’s cheaper than repairing a cracked foundation.

‍

Temporary Power and Construction Utilities

Most people forget they’ll pay for power and water during the build.

• Temporary electrical service: $1,000–$2,000 for setup and teardown, depending on location and panel distance.
• Water usage: Builders often cover some, but on rural land you may need a water tank or temporary meter.

Budget tip: Confirm whether your contract includes temporary utilities or if you’ll be billed directly.

‍

Site Prep, Dirt Work, and Drainage

Even a “flat” lot isn’t truly flat. You may need grading, fill dirt, or drainage adjustments before the foundation goes in.

• Typical grading cost: $2,000–$10,000 depending on slope.
• Extra fill dirt: $200–$300 per load (and you’ll need more than you think).
• French drains or swales: $1,500–$4,000 on average for problem areas.

Budget tip: Get a drainage plan before you pour concrete. Once water starts pooling, fixes cost three times more.

‍

Permits, Inspections, and Impact Fees

Tulsa’s permit process is digital and efficient — but not free.

• Building Permit: Around $1,200–$2,500 for a standard single-family home depending on square footage.
• Mechanical/Plumbing/Electrical Permits: $50–$200 each.
• Impact Fees: Some suburbs (like Jenks or Bixby) charge extra for infrastructure improvements.

Budget tip: Have your builder itemize all permits up front — especially if you’re building outside Tulsa city limits.

‍

Change Orders and Design Upgrades

It starts small: “Let’s upgrade that tile,” or “Add a pot filler.” Before you know it, you’ve added $20K to your build.

• Cabinetry & counters: Custom designs often run $8,000–$15,000 more than base options.
• Electrical upgrades: Adding recessed lights, plugs, or switches? Each outlet averages $75–$150.
• Windows & doors: Expanding openings or changing styles can cost thousands.

Budget tip: Decide your “must-haves” early, and get every selection in writing before construction starts.

‍

Landscaping and Exterior Finish Costs

Your builder’s contract usually includes basic grading and seed — not full landscaping.

• Sprinklers & sod: $4,000–$8,000 depending on lot size.
• Fencing: $25–$35 per linear foot for wood; more for metal or composite.
• Driveways & sidewalks: Long or curved drives can add thousands in concrete cost.

Budget tip: Treat landscaping as a Phase Two project — but set money aside now so your home doesn’t sit unfinished outside.
