Mailbox Micro-Guide for Ontario

Start your project by measuring from the road grade to the mailbox floor. USPS recommends 41 to 45 inches, which we confirm during every service visit. Ontario routes see frequent curb height changes after resurfacing, so we shim the box and re-pour footings as needed.

Setback is equally important—Ontario carriers prefer a 6 to 8 inch gap from the face of the curb to the mailbox door. Follow USPS curbside mailbox height (41-45 inches) and confirm California DOT setback plus local permitting before installation. may request decorative posts stay outside of sidewalk easements, so we map property lines before digging.

We build posts with pressure-treated pine, cedar, or steel. For frost heave protection we auger at least 18 inches below grade and set concrete footings, adding gravel for drainage.

Before excavation we schedule Miss Utility to mark underground lines. After install we verify flag swing, door closure, and alignments to keep USPS satisfied.

Always reference USPS Publication 5 or your HOA handbook for the latest requirements. This guide is informational only.
