TL;DR. Look up the zoning district on any Tucson address in about 20 seconds. Buildability™ returns your exact zone code (like R-1 or RM-2), what's permitted under that zone, the setback and height limits that apply, and any overlay districts that layer additional rules on top. Free for your first check.
Understanding Tucson zoning districts
Tucson's zoning is built around a handful of base districts. Residential zones (often R-1, R-2, RM-1, etc.) control single-family and multi-family housing with different lot size, setback, and height limits. Commercial zones (C-1, C-2, C-3) permit retail, office, and mixed-use. Industrial zones (I or M) cover manufacturing, warehousing, and heavy uses. Mixed-use and transit-oriented zones layer housing above commercial. Buildability™ returns your exact district and decodes what it means for your specific Tucson parcel.
Overlays and the things that trip people up
Arizona state law often overrides or supplements Tucson zoning — especially on ADUs, density bonuses, and ministerial approvals. A Tucson ordinance might say one thing while state law says another; the state law usually wins. Buildability™ reads both layers and tells you what actually applies.
