Building Setbacks & Zoning in Sahuarita, AZ

Sahuarita maintains 89 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Sahuarita falls on the strict-to-permissive spectrum compared to other cities.

Setback Rules

Sahuarita's zoning code sets minimum yard setbacks for single-family homes by district in Table 18.12-2. The RH zone needs 50-foot front, street-side and rear yards with a 20-foot interior side; the compact R-5 zone drops to a 20-foot front yard, as little as 0 feet on an attached interior side, and only a 10-foot rear yard. Substandard lots of record get separate reductions.

Key details: RH front/street-side setback: 50 ft. R-5 front setback: 20 ft. R-4/R-5 interior side (detached/attached): 5 ft / 0 ft. Town-wide street side setback: 20 ft. Narrow-lot side yard floor: 5 ft under §18.07.020(B)(3).

Setback violations are civil infractions under STC § 18.95.030, enforced by the zoning administrator through site inspection, written notice to correct, and citation. STC § 18.95.040 caps penalties at $750 per offense for an individual and $10,000 for a corporation, association or labor union, with each day a setback violation continues counted as a separate offense. The town attorney can also seek an injunction or abatement order to force removal of a structure built in violation of the required yard.

Lot Coverage Limits

Sahuarita caps maximum lot coverage at 60 percent in the R-3 zone, 70 percent in R-4, and 75 percent in R-5 under Table 18.12-2 of Town Code Section 18.12.040, while the RH, GR-1, SR, R-1, and R-2 zones carry no coverage figure in that table. The 60 percent R-3 figure applies only to lots platted after July 1, 2023.

Key details: R-3 max lot coverage (post-2023 plats): 60%. R-3 max lot coverage (pre-2023 plats): 50%. R-4 max lot coverage: 70%. R-5 max lot coverage: 75%. RH, GR-1, SR, R-1, R-2: No figure listed in table.

A main building that exceeds the applicable lot coverage percentage is a zoning violation under Town Code Section 18.95.030, enforced through zoning administrator inspection, written notice, and citation, with building safety authorized to suspend construction that does not conform to approved plans. Section 18.95.040 sets the maximum penalty at $750 per offense for an individual or $10,000 for a corporation, each day a separate offense before the town magistrate.

Structure Height Limits

Single-family homes in every Sahuarita residential zone, from the five-acre RH zone down to the compact MH zone, are capped at 34 feet under Table 18.12-2 of Town Code Section 18.12.040. Multifamily buildings in the R-4 zone share the same 34-foot cap, while R-5 multifamily buildings may reach 40 feet.

Key details: Single-family max height (all zones): 34 ft.. Multifamily R-4 max height: 34 ft.. Multifamily R-5 max height: 40 ft.. Zoning permit required: Concurrent with building permit.

A structure built above the applicable height limit is a zoning violation subject to Section 18.95.030, which lets building safety suspend construction that does not conform to the approved plans and lets the zoning administrator issue a citation. Section 18.95.040 caps the penalty at $750 per offense for an individual or $10,000 for a corporation, with each day of a continuing height violation counted as a separate offense before the town magistrate.

The Bottom Line

Sahuarita's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Sahuarita is broadly strict or permissive.
