How big you may build it

A blank cell means this dataset carries no number for that standard — read it as “go and look”, not as zero.

Dimensional standards from MZO 11-6-2 / 11-6-3 (Table 11-6-3.A) / 11-31-31.

Standards notes. Front and street-facing side vary by street classification in the Mesa Transportation Plan: arterial 15 ft, collector 15 ft, local 20 ft, freeway 30 ft for buildings and 15 ft for parking structures/fields. Value in setback_front_ft is the arterial/collector case. Interior side and rear adjacent to an RS district: 25 ft (1 story), 50 ft (2 story), 75 ft (3 story). Adjacent to an RM district: 20 ft first story plus 15 ft per additional story. Adjacent to a non-residential district: 15 ft per story. Minimum lot depth 100 ft. max_du_per_acre_derived is the CODE-STATED maximum residential density (Table 11-6-3.A); Section 11-31-31(A)(2) restates it as 15 du/acre in NC and 25 du/acre in LC and GC. Projects exceeding it require a Council Use Permit. Minimum outdoor living area 100 sf per unit. Setback at street intersections: 25 ft radius arterial/arterial and arterial/collector, 15 ft collector/collector

No district in this dataset publishes a floor area ratio: intensity in this code is governed by lot coverage, height and — for residential — density or minimum lot area per dwelling unit. See the metro page for the provenance note on that.

Before you rely on this

base district only; overlay geometry not checked — an Airfield or Form-Based Code designation can flip answers

This is a base-district reading of the ordinance text, transcribed from the source below. It is not a Zoning Verification Letter, not a determination by the jurisdiction, not legal advice, and not a substitute for asking the planning department about a specific parcel. Overlays, recorded plan conditions, rezoning stipulations and parcel geometry are not checked here, and any one of them can change the answer on this page.

Verify locally before you spend money. Call the planning counter, pull the parcel's zoning-map designation and its case history, and confirm the section cited above still reads the way it reads here.
