Accessory Structures in Sahuarita, AZ

If you live in Sahuarita or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Sahuarita has 3 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

Shed & Carport Rules

Sahuarita sets separate dimensional standards for detached accessory buildings, such as sheds and workshops, in STC § 18.12.040's Table 18.12-4. Front setbacks run from 30 feet in GR-1 up to 100 feet in the SR zone, and a detached accessory building can sit right up against the main house with a 0-foot separation.

Key details: Front setback range: 30-100 ft by zone. Setback to main building: 0 ft (may touch). Nonanimal side/rear setback (R-2 to MH): 4 ft. Animal-use setback (SR zone): 100 ft. Lot coverage cap: 10% of lot area.

Accessory building setback or coverage violations are civil infractions under STC § 18.95.030: the zoning administrator inspects, issues written notice to correct or remove the structure, and can cite the property owner. STC § 18.95.040 caps the penalty at $750 per offense for an individual or $10,000 for a corporation, with each day the oversized or misplaced building remains treated as a separate offense.

Tiny Homes

Sahuarita permits stick-built tiny homes in any residential zone under Town Code Section 18.12.030(W), while a tiny home on wheels may serve as the main house only in the RH, GR-1, SR, and MH zones once it is anchored to a foundation and skirted or ground set. Wheeled tiny homes are otherwise permitted by right only in the MH zone.

Key details: Stick-built tiny homes: Permitted in any residential zone. Wheeled tiny home as main house: RH, GR-1, SR, MH zones only. Wheeled tiny home by right: MH zone only. Required for wheeled units: Foundation, skirted or ground set.

Placing a wheeled tiny home as a main house outside the permitted zones, or without the foundation and skirting requirement, is a civil infraction under Town Code Section 18.95.030, enforced through zoning administrator inspection, written notice, and citation. Section 18.95.040 sets the penalty at up to $750 per day for an individual or $10,000 for a corporation, with each day a separate offense before the town magistrate.

ADU Rules

Sahuarita limits homeowners to one accessory dwelling unit per lot under Town Code Section 18.12.030(C), capping the ADU at 1,000 square feet on lots of at least 11,000 square feet. Height and parking follow the main house, and manufactured or wheeled tiny-home ADUs need a Type I conditional use permit outside the RH and GR-1 zones.

Key details: Max ADUs per lot: 1. Minimum lot size: 11,000 sq. ft.. Max ADU size: 1,000 sq. ft.. Extra parking required: 1 space. Max civil penalty: $750 individual / $10,000 corporation, per day.

An unpermitted or oversized ADU is a civil infraction under Town Code Section 18.95.030: the zoning administrator inspects, serves written notice to correct or cease the violation, and issues a citation if it continues. Section 18.95.040 sets the maximum penalty at $750 per offense for an individual or $10,000 for a corporation, with each day of continued violation a separate offense decided by the town magistrate.

The Bottom Line

Sahuarita's accessory structures 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.
