Pool Construction in Collegedale, TN
An incorporated city of about 11,109 across 9.9 square miles, with its own codes office and its own code edition. Here the ground comes first, because on this side of the county rock is the base case.
The ground: shale at 20 to 40 inches
This is Apison and Armuchee soil country on the eastern side of the county. Apison soils reach weathered shale at 20 to 40 inches. Armuchee reaches it at 20 to 36. That is shallow — shallower than the floor of any inground pool.
On these map units, rock is the base case rather than the exception. A quote for a Collegedale pool that does not mention rock excavation has not accounted for it, and the number will move once the machine is in the ground. That conversation belongs before the contract, not during the dig.
For the format-by-format numbers, including what rock excavation and hoe-ram days add, see the Chattanooga pool cost guide. There is no separate Collegedale price list — the ground is what differs, not the rate.
The permit wrinkle worth knowing about
Collegedale was incorporated in 1968 and is home to Southern Adventist University. It runs its own Building & Codes Department at 4910 Swinyar Drive, main line 423-396-3135. A permit is required for any work valued at $1,500 or more, so no pool project here avoids one.
The wrinkle: Collegedale enforces the 2012 International Residential Code, while Hamilton County moved to the 2018 codes — including the 2018 International Swimming Pool and Spa Code — effective January 1, 2022. Two adjacent jurisdictions, two different code editions, and the differences land on barrier, gate and entrapment details. Confirm which one applies to your address before anyone prices a fence.
Second quirk: the Ooltewah CDP is an enclave inside Collegedale, so an "Ooltewah" mailing address does not reliably tell you which office issues your permit. The Ooltewah page covers how to sort that out.

Collegedale questions
- Which code edition applies in Collegedale?
- Collegedale enforces the 2012 International Residential Code. Hamilton County moved to the 2018 codes, including the 2018 International Swimming Pool and Spa Code, effective January 1, 2022. Two adjacent jurisdictions, two different editions. Confirm which one covers your address before anyone prices a barrier or a gate detail — call the Collegedale codes office at 423-396-3135.
- Is my Ooltewah address actually in Collegedale?
- It might be. The Ooltewah CDP is an enclave inside Collegedale, so an Ooltewah mailing address does not reliably tell you which office issues your permit. The parcel decides it, not the ZIP code. Call Collegedale at 423-396-3135 or Hamilton County Building Inspection at 423-209-7860 and confirm before you design.
