What is the cost difference between building a 24x24 detached garage versus an attached garage in Rocky View County?

Building a detached 24x24 garage typically costs $3,000-$8,000 more than an attached garage of the same size in Rocky View County, primarily due to additional foundation work, separate electrical service, and increased material requirements.

For a 24x24 detached garage (576 sq ft), expect to pay $35,000-$65,000 depending on finish level and site conditions. This includes a full concrete foundation, separate electrical panel and service, independent heating system if desired, and complete exterior finishing on all four sides. The detached option requires its own building permit from Rocky View County and separate electrical permit through the Safety Codes Council of Alberta system.

An attached garage of the same size runs $28,000-$55,000 because it shares the home's foundation system, electrical service, and one exterior wall. You'll save on foundation excavation, concrete work, and electrical service installation. However, attached garages require careful attention to fire separation between the garage and living space - this means fire-rated drywall, proper door installation, and sealed penetrations per the Alberta Building Code.

Rocky View County considerations add complexity to both options. The county's expansive clay soils require proper foundation design extending below the 4+ foot frost line. Site access for concrete trucks and material delivery can increase costs if your property has challenging terrain or long driveways. Rocky View's rural setting often means longer travel times for trades, potentially adding 10-15% to labor costs compared to urban Calgary projects.

Additional factors affecting the cost difference include utility connections - a detached garage may need trenching for electrical service from your main panel, which can add $2,000-$5,000 depending on distance and ground conditions. If you want water or gas service to a detached garage, expect another $3,000-$8,000 for proper trenching and connections, all requiring separate permits and inspections.

Permit considerations in Rocky View County require building permits for both options, but detached garages need separate electrical permits and potentially development permits depending on setbacks from property lines. Processing time is typically 4-8 weeks for straightforward garage applications.

The best choice depends on your specific needs - detached garages offer more flexibility for noisy activities, better separation from living spaces, and easier future expansion. Attached garages provide convenience, lower costs, and easier access during Calgary's harsh winters. Consider your lot layout, intended use, and long-term plans when making this decision.
