Marana Land Development Code Section 17-4-5 caps residential lot coverage at 40 to 50 percent depending on zoning district. Section 17-7-8 allows increases up to 55 percent when garages are recessed at least 10 feet from the front facade or use rear-entry design.
Lot coverage in Marana is governed by Table 4 of Section 17-4-5 in the Land Development Code. Smaller-lot residential zones such as R-3 through R-6 typically allow up to 50 percent lot coverage, while larger-lot zones like R-10 and R-16 cap coverage at approximately 40 percent. Lot coverage includes the footprint of all structures, covered patios, and carports but excludes uncovered flatwork such as driveways and walkways. Under Section 17-7-8, lot coverage may be increased to 55 percent when the garage is recessed 10 feet or more from the livable portion of the dwelling or when rear-entry garages are used. This modification encourages varied streetscapes in master-planned communities like Continental Ranch and Dove Mountain. Specific plan (SP) zones under Section 17-4-15 may establish custom lot coverage standards through the specific plan approval process.
Exceeding lot coverage limits without an approved modification: civil code violation under Chapter 5-7. Structures contributing to excess coverage may require modification, removal, or a variance application through the Board of Adjustment.
