🛑 Mistakes to Avoid in Sarasota Garage Conversions
❌ Skipping Permits
Florida building code requires permits, inspections, and compliance
Unpermitted work may hurt resale value and insurance coverage
❌ Using Poor Insulation or Windows
Garages weren’t built for comfort—Florida heat demands proper insulation
Impact-rated windows required in most of Sarasota County
❌ Not Extending HVAC Correctly
Portable ACs won’t pass code—install split systems or duct extensions
❌ Leaving the Garage Door
Fails inspections and kills resale value
Must be replaced with a framed exterior wall and window or door
📜 Sarasota Garage Conversion Permits (What You Need to Know)

💡 Design Ideas That Make Garage Conversions Feel Natural
Vault the ceiling (if no attic above) to add space

Use luxury vinyl plank flooring (durable and waterproof)
Install custom built-ins for storage
Open up to adjacent rooms with a wide cased opening
Use barn doors or sliding partitions to save space
