Lean-tos can stand independently, sit beside another building, or attach to a compatible metal building sold by Norcal Carports or built with a similar reviewed framing system. We do not attach lean-tos to houses or conventional buildings.
A lean-to is a single-slope metal structure that can stand on its own, sit beside another building, or connect to a compatible reviewed metal-building frame. Its sloped roof creates versatile coverage with an efficient, space-conscious profile.
Choose standalone support posts, adjacent placement, or an engineered connection to a compatible metal building.
Create dedicated coverage for vehicles, RVs, equipment, livestock, or outdoor work areas.
Standalone lean-tos use support posts along both the tall and short sides, while attached designs integrate only with a compatible reviewed metal-building frame.

Add efficient single-slope coverage wherever your property needs it, whether the structure stands alone or extends an existing building.
Add tall-clearance coverage beside your garage specifically for RVs, motorhomes, and travel trailers.
Commonly used for tractor parking, utility trailers, lawn equipment, and side-by-side protection.
Perfect for livestock shelter, feed protection, hay storage, and rural property equipment staging.
Create shaded outdoor fabrication areas or loading zones as a standalone structure or beside your workshop.
Precise geometry to ensure water flows correctly off the multi-section roof.
attachment points engineered to handle localized wind and snow pressure.
Use of matching gauge steel and support spacing for a unified structure.
Customized slopes to clear obstacles while maintaining proper drainage.
Standalone lean-tos carry loads through their own support posts and anchors. Attached lean-tos are limited to compatible metal buildings sold by Norcal Carports or similar metal-building systems that pass a framing and engineering review. They cannot attach to houses or conventional buildings.
Lean-to structures are commonly configured with vertical roof systems to improve water runoff and debris shedding, especially on larger spans.
Standalone and attached lean-tos may require new anchors, footings, slab work, or structural calculations depending on site conditions and local building codes.
Configuration depends on placement, available space, clearance, site conditions, and your specific utility needs.
