Posts in the Carolands must be set a minimum of 12 inches into concrete footings that extend below the local frost line. IRC Section R403.1.4 requires this to prevent frost heave, which lifts and cracks posts. In moderate corrosivity soils, footings require a 6-inch gravel base for drainage and hot-dip galvanized post bases to meet IRC durability standards.

California Civil Code 841 mandates written notice to adjoining owners at least 30 days before constructing or replacing a shared partition fence. The 2026 amendment requires this notice to include material specifications and a proposed cost share. In Hillsborough, failure to provide this notice can result in a civil penalty and removal orders from the Town Hall.

A site consultation is scheduled within 48 hours of permit approval. The standard route from the Hillsborough Town Hall uses I-280 for access, with a typical 35-45 minute dispatch window. We confirm the arrival time via a tracking link sent the morning of the consultation, which includes the project lead's credentials and a digital copy of the site plan.

The V-ult wind speed of 110 MPH, per ASCE 7-22, dictates the structural design. This requires 4x4 posts at 6-foot centers maximum, set in 12-inch diameter concrete footings. All rail-to-post connections must use 1/2-inch galvanized through-bolts, not lag screws, to resist the uplift forces from peak storm season gusts common near I-280.

Zoning limits are 3 feet in front yards and 6 feet in rear yards. The 0-foot setback allows installation on the property line, but corner lots must maintain a clear 'sight triangle' at intersections. Fences within 10 feet of a driveway apron near I-280 must not exceed 36 inches in height to preserve driver visibility, as per Hillsborough Municipal Code Chapter 17.

Use stainless steel fasteners and hardware with pressure-treated wood rated for ground contact. For moderate termite risk, composite or aluminum panels are superior to cedar. All metal components in moderate corrosivity soils must be hot-dip galvanized (ASTM A123) to prevent rust streaks that stain foundations and violate Hillsborough's design review standards.

State law requires a utility locate request through Underground Service Alert (811) at least two working days before excavation.

Our crew manages the 811 ticket and concurrently files the Hillsborough Town Hall permit application to align the start date.

Yes. An integrated smart gate with an ASTM F1908-16 certified self-closing, self-latching mechanism meets the state's 60-inch minimum height requirement.
