• How long does it take to build a patio cover in San Dimas?

  On-site construction for a patio cover in San Dimas generally takes 2 to 6 weeks. This timeline can extend if your project requires extensive permitting for a large structure or specialized fire-resistant materials due to being in a Very High Fire Hazard Severity Zone.

• Does my 8000 sq ft San Dimas lot affect patio cover rules?

  While an 8000 sq ft lot provides ample space, its specific location within San Dimas is key. If your lot is on a hillside or in the Very High Fire Hazard Severity Zone (ZIP 91773), you will face stricter material and defensible space requirements for any patio cover project.
