Battery storage on land in unincorporated San Diego County

Confirm who reviews this particular property

The county’s BESS planning page describes privately developed facilities in the unincorporated area and distinguishes projects using the state opt-in process. An incorporated city’s requirements may differ. Ask for the proposed reviewing authority before comparing an offer with a county proposal or another project’s permit.

Give the road or address and parcel number if you know it. Ask the project team to identify the boundary, zoning, existing uses and any applicable plan. Keep an owner-readable map with those answers. If the company changes its proposed route, ask how that affects its schedule, costs and requested land rights.

The authority reviewing land use does not necessarily settle the electrical connection. Ask which utility or CAISO application supports the actual battery design, and what that application has established so far. A permit application and an approved connection are separate records.

Separate proposed zoning from current requirements

At the October 7, 2026 check, the county still presented its August BESS zoning amendment as a draft. Its listed public-comment period had ended. That is not evidence that the proposed classifications had become adopted rules.

If a developer says the property qualifies under the new ordinance, ask for the adopted text, effective date and explanation applying it to the parcel. The draft contains differences between its tier table and written descriptions. Have the responsible authority confirm the classification rather than calculating one from a promotional summary.

An uncertain review process deserves clear private deadlines. Ask how long the company would hold the land while rules or applications remain unresolved, what it pays during that period and when you can regain unrestricted use. A possible future rule does not supply those terms.

Ask who handles the fire study and its consequences

The posted county fire code contains a technical-study provision for BESS of at least 600 kilowatt-hours, covering all battery types, with an April 2, 2026 effective-date notation. Confirm the applicable fire authority and current requirements for the actual property. Do not assume the draft zoning threshold answers the fire-review question.

Ask who commissions the study, who pays and which design it evaluates. What happens if the reviewing authority requires more space, different equipment or another access route? Request a revised layout before agreeing to a larger reserved area. Technical work can affect the rest of the property as well as the equipment footprint.

The owner need not design the safety system. The developer should explain the required review, identify its qualified specialists and show which issues remain open. Ask for the actual determination if the company says it received a modification or exception; that claim should be tied to the specific project.

Use parcel records to understand what is already approved

The county’s July 2026 PDS-318 handout points to zoning and general-plan information, initial-study research, permit forms, plot plans and decisions. It also cautions that its document library does not contain every record and that keyword searches do not find everything.

Ask the developer for the actual application number, applicant name and decision documents. Compare the approved footprint and conditions with the proposal you have received. If a search produces no result, request the relevant record rather than assuming there is no application or no restriction.

Keep preliminary research separate from approval. A map or initial consultation may help identify questions, but your adviser still needs the documents that govern the proposed use. Discuss who would pay any consultation, study or application expenses before authorizing them.

Review what an owner signature would authorize

Ask whether the requested signature permits research, filing, entry onto the land or exclusive occupation. Those are different rights. Read an owner-consent letter alongside the option and its map, including any terms for tests, roads, cables and temporary construction work.

Identify the entity making the application and the entity promising to pay you. Ask whether either may transfer its role and what notice or consent you retain. If the project needs neighboring land, find out what happens to your agreement while those rights are still being negotiated.

A signature does not by itself settle rent, construction permission or the right to alter the property. Have the documents explain when each right begins, what conditions apply and how it ends. Retain copies of what you signed and of any later amendment.

Keep restoration and payment duties clear as the design changes

The county’s draft addresses removal funding and updates when a project changes. Those proposed provisions do not replace the restoration obligations in your private agreement.

Ask which equipment, roads and cables must be removed, who restores drainage and surfaces, and what financial backing supports that work. If the battery design or project area changes, discuss whether the agreement, restoration estimate and supporting security need to change too. Have your adviser compare public conditions with the protection available to you privately.

Keep your payment dates clear while the company works through reviews. What is due during the option? What starts rent? What happens if the project stops or an extension expires? Those answers should come from the agreement you are reviewing.

To ask Sunland about your land, begin with your contact details and property location. Acreage and parcel number are optional. You do not need to send private agreements or commission a study to make an initial inquiry.
