Summary
Rain barrels and cisterns count as "ancillary equipment" under City Code § 16.50.020.4.2: allowed citywide but subject to the same setback, one-foot ground-height cap, and street-facing screening rules that apply to pool pumps and solar panels, not a special rainwater-specific permit.
For the purposes of this section, "ancillary equipment" means: ... Renewable energy devices and other sustainable development technologies including, but not limited to, solar photovoltaic (pv) panels, solar hot water, solar pool heaters, tankless water heaters, geothermal heat pumps, gray-water systems and rainwater harvesting devices, such as rain barrels and cisterns. ... Ancillary equipment in traditional and suburban zoning districts shall comply with the following:1.Setbacks shall comply with those listed in the Setbacks, Allowable Encroachments Section.2.The base of ground-mounted equipment shall not exceed one foot above ground level. ... 4.The sides of any new or replacement equipment facing or visible from a street, excluding alleys, shall be screened with material that is compatible with the architectural style of the principal structure, landscaping, or a six-foot-tall decorative fence or wall.

Full Breakdown
St. Petersburg doesn't ban rain barrels or cisterns, it regulates them as a category of "ancillary equipment" alongside air conditioning compressors, pool pumps and solar panels. " In the city's traditional and suburban zoning districts, subsection (B) requires that this equipment meet the setbacks in the Setbacks, Allowable Encroachments section, and caps the base of ground-mounted units at one foot above grade, taller installations must instead be elevated on a cantilevered platform attached to a structure and kept within one foot of the minimum design flood elevation used for flood protection.
Any new or replacement unit visible from a street (alleys don't count) has to be screened with material matching the principal structure's architecture, landscaping, or a solid decorative fence or wall at least 6 feet tall. Equipment already installed lawfully in a nonconforming spot can be swapped for a unit of similar or lower capacity without losing its status. In all other, non-traditional/suburban zoning districts, the code instead ties the required setback to whether the equipment abuts a residential use, and always requires screening from adjacent properties and streets.
Violations & Fines
Installing a rainwater harvesting device that violates the setback, height, or street-screening standards in § 16.50.020.4.2 is a Land Development Regulations violation; the POD can require relocation or screening, and an unresolved case proceeds to the Code Enforcement Board, which may impose fines up to $250 per day past the compliance deadline under § 9-29.
