Bloomington Garage Permit & Zoning Requirements

Verify My Address (Fast Answer)
Bloomington garage rules vary by zoning district (R-1, RS-1, R-1A), lot orientation, and whether the garage is adjacent to a public street. If you share your address and your target garage size, we can usually confirm key zoning items (setbacks, height limits, driveway notes) before design and permitting.
Response time: Usually within 1 business day.
Garage Size & Permit Thresholds
- Building permits are not required for accessory buildings 200 sq ft or less.
- Larger garages require a building permit and a survey or scaled site plan.
- Permit applications typically list garage size, sidewall height, roof height, and setbacks.
Practical note: Most permit delays happen when setbacks, street-side yard rules, driveway changes, or height measurements are unclear. We confirm these early so your permit set matches what the City expects.
Bloomington Setback Requirements (Detached Garages)
Typical minimum setbacks vary by zoning district:
- Front Yard: R-1 / RS-1: 30 ft · R-1A: 75 ft
- Side Yard: 5 ft
- Rear Yard: R-1 / R-1A: 5 ft · RS-1: 10 ft
- Side Yard Adjacent to Public Street: R-1 / RS-1: 30 ft · R-1A: 75 ft
Prevailing setbacks may apply in some cases and should be verified for your specific lot.
Height Rules
- Detached garages may not exceed the height of the dwelling.
- Garage door openings may not exceed 8 ft.
- Accessory buildings (non-garage) are limited to 15 ft max height.
- Height is measured from the lowest exterior grade to roof peak.
Driveway Requirements
- Most garages must be served by a driveway.
- A separate driveway permit may be required when adding or modifying a driveway.
- Standard minimum side setback for driveways is typically 5 ft.
Fire-Resistance & Separation Rules
- Garages located less than 3 ft from a dwelling on the same lot may require 1/2" gypsum board on interior walls within that zone.
- Openings and projections near property lines may require 1-hour fire-rated construction depending on distance.
- Attached garages require additional fire separation between house and garage.
Permits, Variances & Inspections
Detached garages in Bloomington typically require a building permit (unless exempt by size). Variances may be required if a garage does not meet zoning or setback rules and must be approved before a permit can be issued.
Common inspections include:
- Footing / slab
- Rough-in (plumbing, electrical, mechanical)
- Framing
- Insulation
- Final inspection
