This page is general information, not legal advice. Shared driveway questions turn on your deed, any recorded easement or agreement and the facts on the ground. For a real dispute, speak to a California real estate attorney.
Who pays for a shared driveway?
Start with the paperwork. If a recorded agreement or easement sets out how costs are split, that controls. Where there is an easement and no agreement, California Civil Code section 845 says the cost of keeping a private right of way in repair is shared by the owners in proportion to the use each one makes of it. Equal use points to an equal split. If one owner runs heavy trucks over it every day, that owner's share is larger.
How do I find out if there is an easement or agreement?
Look at your deed and your title report from when you bought the house. Easements and maintenance agreements are recorded with the county, which here is the Solano County Assessor/Recorder. A title company can pull the recorded documents for a fee. Do not rely on what a previous owner said.
My neighbor will not pay. Can I replace only my half?
Physically, yes, if the lot line runs down the middle and you stay on your side. A joint is cut along the line and only your half is replaced. The result is two surfaces of different age and color, and the old half may keep moving beside the new one. Before you do that, put your request to share the cost in writing. Civil Code section 845 describes a written demand and a court process for recovering a share of repair costs on an easement. An attorney can tell you whether that fits your situation.
Can a contractor's trucks use a shared driveway?
Only within the rights you have. If the easement gives you access, that normally covers trucks working on your property, but it does not let you block the neighbor or damage the surface. Tell the neighbor the dates in advance. A loaded ready-mix truck is very heavy and can crack an old thin driveway, so we look at whether to pump from the street or use smaller buggies instead.
What if the shared driveway is damaged during my project?
Whoever causes damage is generally expected to repair it. Photograph the driveway with the neighbor before work starts so there is no argument about what was already cracked. Ask your contractor in writing how the surface will be protected and confirm that the contractor carries liability insurance.
Can we replace a shared concrete driveway together?
Yes, and it gives the best result: one pour, one color, one set of joints. Agree the split in writing first, name one contact for decisions and ask for the contract to show each owner's share. If no maintenance agreement exists, this is a good time to have an attorney draft one and record it, so the next owners are not left guessing.
