A 2-car garage addition in Rhode Island recoups approximately 80–90% of its cost at resale, making it one of the best home improvement investments. In markets where homes without garages are uncommon, ROI can exceed 100%. For a $33,000 garage, expect to add $26,400–$29,040 in home value. Beyond ROI: vehicle protection reduces car depreciation by $500–$1,500/year, and garages dramatically improve home desirability.

Yes — garage additions require building permits in virtually all Rhode Island jurisdictions. This involves structural, electrical, and drainage permits. Permit costs typically run $500–$1,500 in Rhode Island. In coastal and wildfire-prone areas, additional requirements (fire separation, hurricane straps) add cost and inspection requirements. Never build without permits — unpermitted garages create major complications at home sale.

Attached garages in Rhode Island cost 15–25% less than detached ($NaN vs. $NaN for 1-car). Attached provides direct home access — especially valuable in cold Rhode Island winters. Detached is better for workshops (noise/fumes), has more design flexibility, and slightly higher standalone resale value. For most Rhode Island homeowners, an attached 2-car garage is the best investment.
