Summary
Chicago requires a building permit before installing a hot tub or spa deep enough to count as a swimming pool, plus a self-latching 5-foot fence, and requires it be kept clean, sanitary, and in good repair.
It shall be unlawful to proceed with the construction, installation, enlargement or alteration of any private residential swimming pool or appurtenance without a building permit... Pools shall be completely enclosed by a fence or walls erected along the perimeter of the pool deck... Fences and gates shall be at least 5 feet (1525 mm) in height above the grade level outside the enclosure... All gates shall be equipped with self-closing and self-latching devices placed at least 54 inches (1372 mm) above adjacent walking surfaces.

Full Breakdown
Chicago's property maintenance code names spas and hot tubs directly: they "must be maintained in a clean and sanitary condition, and in good repair," and private residential units "must comply with the Chicago Plumbing Code" (14X-9-908). That Plumbing Code defines a regulated "swimming pool" as any structure or basin holding water 2 feet deep or more for bathing or recreation, a threshold most in-ground and many above-ground spas and hot tubs meet. Once that threshold is met, a City building permit is required before installation, and the unit must be fully enclosed by a fence or wall at least 5 feet tall with a self-closing, self-latching gate.
Violations & Fines
Installing, enlarging, or altering a pool, spa, or hot tub without the required Chapter 14A-4 building permit is unlawful under §18-29-1204.3; missing or non-compliant enclosures and unmaintained equipment are cited by the Department of Buildings under the plumbing and property maintenance codes.
