How Broken Arrow Handles Accessory Structures: A Practical Guide

Broken Arrow maintains 41 local ordinances across all categories, and 4 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Broken Arrow falls on the strict-to-permissive spectrum compared to other cities.

Carport Rules

Broken Arrow regulates carports as accessory structures under Chapter 3 of the Zoning Ordinance (Appendix A) with dimensional limits set in Chapter 4. In the R-2, R-2S, R-3, RS-3, RS-4, and RD residential districts the maximum size of any accessory building is 1,000 square feet absent a Specific Use Permit. The Residential District Design Guidelines additionally restrict garage and carport placement: no projection forward of the principal structure's front-most wall, with minimum front setbacks ranging from 20 to 35 feet depending on the design Area.

Key details: Accessory Cap (R-2, R-3, RS-3 etc.): 1,000 sq ft. Code Reference: Zoning Ord. Ch. 3 Sec. 3.3.C. Front Setback: 20-35 ft (by Area). Forward Projection: Prohibited (past front wall). Driveway Max Width: 25 ft.

Building a carport without zoning clearance or a building permit, exceeding the 1,000 sq ft accessory-building cap in R-2, R-2S, R-3, RS-3, RS-4, or RD districts without a Specific Use Permit, projecting a carport forward of the principal structure's front wall, or violating the design-Area front-setback minimum is enforceable by Broken Arrow Code Enforcement and Development Services. Remedies include stop-work orders, after-the-fact permitting, civil fines through Broken Arrow Municipal Court, and an order to remove the noncompliant structure.

ADU Rules

Broken Arrow zoning ordinance allows ADUs in certain residential districts. ADU front must be placed behind the rear wall of the primary structure. Side setbacks are 5 feet minimum in most areas with transitional setback requirements. Rear setback is 10 feet minimum in most areas. Tiny homes are not permitted as ADUs under Broken Arrow's adopted 2015 IRC. RVs cannot be used as permanent residences (14-day max occupancy).

Key details: Placement: Behind rear wall of primary structure. Side Setback: 5 ft minimum. Rear Setback: 10 ft minimum. Tiny Homes: Not permitted as ADUs.

Unpermitted ADU: standard building code enforcement. May require demolition or legalization. Occupying unpermitted dwelling: code violation.

Shed Rules

Broken Arrow requires permits for accessory structures including sheds. The city has adopted the 2015 International Residential Code.

Garage Conversions

Garage conversions in Broken Arrow require a building permit from Community Development. The conversion must meet the adopted 2015 IRC standards for habitable space including egress, ventilation, insulation, and electrical. A change of occupancy review is needed. ADU conversions must comply with zoning ordinance placement and setback rules. The structure must remain behind the rear wall of the primary residence if used as an ADU.

The Bottom Line

Broken Arrow'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 Broken Arrow is broadly strict or permissive.
