Pool Builders in Spring, TX: Harris County Permits, Floodplain & Free Matching

Harris County side: what the County Engineer requires

For unincorporated Harris County, residential pool permits come from the Office of the County Engineer (OCE), and plan approval is required.^[1]

Outside the floodplain: submit a site plan and application. No inspection is required.^[1]
Inside the floodplain: also submit a pool electric-disconnect drawing. The pool gets a field inspection, and an As-Built Certificate is required after construction.^[1]
Excavated dirt must be removed from the site or permitted under the county’s floodplain regulations.^[1]

Processing takes 10 business days.^[1] Our Cypress page lays out the same county process in a side-by-side table.

Creeks and flood zones

Spring Creek and Cypress Creek both run through the area, so plenty of lots sit in or near a mapped floodplain. Look up your address on FEMA’s Flood Map Service Center before you settle on a design.^[2] It affects paperwork, inspections and where the dirt can go.

Montgomery County side

If your Spring address is north of Spring Creek, you’re likely in Montgomery County. Requirements depend on your exact location, floodplain status and utility district. Ask your builder which permits and approvals they’ll handle.

Renovations, patio covers and outdoor kitchens

Pool renovation. If your pool needs a new finish, tile and coping, or equipment, ask whether the work needs a county permit. See our pool renovation guide.
Patio covers and pergolas. Many Spring subdivisions have HOAs with architectural review. Get approval before you build. Our patio cover guide explains how Texas HOA review works.
Outdoor kitchens. Gas and electrical runs from the house are often the biggest variable. Ask who is licensed to do each.

Budget: start with published Houston-area ranges

Angi’s Houston page (updated August 2026) puts most inground pools at $51,832–$100,605, averaging $75,337.^[3] For resurfacing, Angi’s Houston resurfacing page (updated April 2026) puts the average at $10,846, with most homeowners spending $5,916–$14,790.^[4] These are third-party estimates for the Houston area, not quotes. Size, soil, access, finishes and permits all move the number. For patio covers and outdoor kitchens, see the published ranges in our patio cover cost guide and on our outdoor kitchens page.
