Counts are permits issued per calendar month as Mesa publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.
How long do permits take in Mesa?
Based on 14,566 Mesa permits applied for between Nov 2023 and Aug 2026, the typical (median) permit was issued 26 days after application, and the middle half of permits took 15–80 days. One in ten took longer than 239 days.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice. How we calculate approval times.
Housing law — Arizona
Arizona's HB 2720 (2024) requires municipalities with more than 75,000 residents to permit at least one accessory dwelling unit on lots where single-family homes are allowed; cities that did not adopt conforming rules by January 1, 2025 must allow ADUs on all residential lots.
Arizona's HB 2721 (2024) requires cities over 75,000 to allow 'middle housing' — duplexes through fourplexes and townhomes — by right near central business districts, with compliance by January 1, 2026. A separate 'Starter Homes Act' did not become law (vetoed in 2024, stalled in 2025).
Mesa ADU rules
Mesa permits internal, attached, and detached accessory dwelling units by right in all of its single-residence zoning districts, under Mesa Zoning Ordinance Section 11-31-3 as updated by Ordinance No. 5883 (2024) and Ordinance No. 5950 (July 2025) to comply with Arizona's House Bill 2720. There is no minimum lot size to add an ADU, and each unit must have its own independent entrance and separate water, sewer, and electric service.
A detached ADU's interior habitable area is capped at 75 percent of the primary residence's habitable area or 1,000 square feet, whichever is less. Consistent with HB 2720, Mesa does not require additional off-street parking for an ADU and may not impose an owner-occupancy mandate, and setbacks are limited by state law. A notable 2025 amendment removed the requirement to replace covered parking when a garage is converted into an ADU — a rule that had previously stalled many garage-conversion projects on tighter lots, since converting existing space such as a basement, attic, or attached garage is often the lowest-cost path to an accessory unit.
Because a code-compliant ADU is a by-right use, a conforming Mesa casita is reviewed administratively through the building permit rather than a discretionary hearing.
