Summary
Single-family homes in Maricopa's RS-1, RS-3, RS-4 and RS-5 zoning districts are capped at 30 feet under Table 18.35.030. Height is measured from natural or finished grade to the highest point of the structure, and a defined list of rooftop features (solar panels, chimneys, elevator towers) may project above that limit.
Table 18.35.030 prescribes development regulations for the RS Districts. The first six columns establish minimum requirements for permitted and conditional uses... Maximum Building Height (ft.): RS-1 30, RS-3 30, RS-4 30, RS-5 30. ... Measuring Building Height. Building height is the vertical distance measured from the natural grade to the highest point of the structure directly above the natural grade when such structure is not located on a platted subdivision. If the structure is located in a platted subdivision, height shall be the vertical distance measured from the finished grade as shown on the subdivision grading plans or finished grade as shown on the individual lot's grading plan (whichever is lower) to the highest point of the structure directly above the finished grade.

Full Breakdown
Maricopa City Code § 18.35.030, Table 18.35.030 sets Maximum Building Height at 30 feet across all four single-family residential districts: RS-1, RS-3, RS-4 and RS-5. A footnote to the table adds that in RS-5 Districts, street-facing garage entrances must sit at least 18 feet from the property line, separate from the height cap itself.
MCC § 18.15.030(E)(1) defines how that 30 feet is measured: from natural grade to the highest point of the structure directly above natural grade if the lot is not in a platted subdivision, or from the lower of the subdivision grading plan or individual lot grading plan finished grade if it is platted.
The table cross-references MCC § 18.80.080, Exceptions to height limits, which lists specific structures allowed to project above the 30-foot cap: skylights (1 foot), solar panels (3 feet), rooftop wind turbines and other energy facilities (5 feet), chimneys and decorative features such as domes and cupolas (20% of roof area, up to 20% of the base height limit or 10 feet), elevator and stair towers on multi-unit or nonresidential buildings (12 feet), mechanical penthouses (60% of roof area, 10 feet), flagpoles (10 feet, one per residential lot, set back at least the pole's height from lot lines), and parapets on non-detached-residential structures (4 feet). No portion exceeding the height limit may be used for sleeping quarters or advertising.
A homeowner who wants to exceed the district height limit outside these exceptions must apply for a variance under MCC Chapter 18.160; the hearing officer decides variances, with a 10-day window to appeal that decision to the city council.
Building a structure taller than 30 feet without an approved exception or variance is a code violation enforced under MCC § 18.190.060.
Violations & Fines
Height-limit violations are enforced as zoning code violations under MCC § 18.190.060. A first infraction carries a base fine up to $100, a second violation of the same section on the same property within a year up to $200, and further violations up to $500 each; any violation can instead be charged as a misdemeanor, punishable by a $500-$1,000 fine, up to six months in county jail, or both. Civil penalties can also reach $1,000 per day the violation continues.
