CALIFORNIA58 | PROPERTY & BUILDING GUIDE | OCTOBER 18, 2026. An electric line, water main, gas pipeline or sewer easement can limit where a homeowner places a house, garage, retaining wall, tree or fence. The restrictions depend on the recorded grant and the utility’s applicable requirements.

Start with the recorded easement

Ask the title company or county recorder for the recorded instrument, legal description and exhibit. A utility corridor shown on a map may not tell the full story. Some rights are exclusive; others allow limited compatible surface uses.

Structures and access

Utility holders may require access for maintenance, repair and replacement. Never assume a patio, shed, wall, driveway or tree planting is allowed just because a neighbor has done something similar. Request written guidance from the utility and local permitting authority.

Underground safety

Before digging, California property owners and contractors should contact the regional 811 notification service. Utility markings identify approximate facilities for safe excavation, not legal property boundaries or easement limits. See California’s underground service alert information.

What to check before closing

Compare the easement documents with a survey and the proposed site plan. Confirm setback, building, fire-access and engineering constraints with the appropriate local agencies. A utility’s consent may not replace a building permit.

Practical checklist

  1. Verify the parcel’s legal description and jurisdiction.
  2. Request recorded documents and relevant public records.
  3. Describe the exact project to the local planning and building departments.
  4. Ask for written permit and technical-study requirements.
  5. Budget for qualified professional review before making irreversible commitments.
