How El Cajon handles building permits

Building Safety, part of the Community Development Department at 200 Civic Center Way, provides plan check and inspection of new buildings and structures, permitting and inspection of mobile home installations, inspection of substandard properties, graffiti eradication and citizen complaints.

The general information line is 619-441-1726 and the building email is Building@elcajon.gov. The city says state law requires it to apply the code in effect when plans are submitted and that it cannot approve projects that do not comply, and it notes that the 2025 California Building Standards Code changes took effect January 1, 2026.

How the PACO application process works

1. Register for PACO. The Project Assistance Center Online is the portal for plan check submittals, permit payment, inspection requests and status updates. The city adopted a new log-in procedure on April 15, 2024.
2. Apply. Choose the permit or plan type, select the property, enter the required information, identify required forms, upload forms and plans, and submit. Submittals are electronic.
3. Pay the initial invoice. Within one to two business days you receive an email directing you to pay the initial plan check or review fee. Review begins after payment.
4. Respond to corrections. After review, which varies in length, the city emails you to view corrections, redline plans or additional invoices. Revise and resubmit through PACO.
5. Receive approval and pay final fees. Approvals are uploaded to PACO, and you may receive a final invoice.

Typical forms mentioned by the city include a certification of easements, energy efficiency documentation and a hazardous materials questionnaire. If you cannot find the property address in PACO, it is probably outside city limits, since many unincorporated San Diego County addresses list El Cajon as their city.

Owner-builder and contractor permits

An owner can obtain a permit to do work on their own property by providing a completed owner-builder declaration, a permit application with a job description and proof of ownership.

A contractor permit requires an application with a project description, a workers’ compensation certificate, Contractors State License information and a current City of El Cajon business license. Reroofs need a reroof application, and new or upgraded electrical meters need documentation of the approved location from SDG&E.

This matters to sellers because work done by an owner-builder still needs the permit and inspection record, and a buyer’s lender or title company may ask for it.

Inspections and what to do once you have a permit

After the permit is issued, you can begin work, and the required inspections are listed on the permit’s inspection sheet. The city warns not to cover any part of construction, such as underground work or wall framing, until it has passed inspection. Daily inspection times, results and corrections are posted online through PACO. Construction and demolition projects must divert 65 percent of waste from the landfill.

How to check the permit history of an El Cajon house

• The city posts monthly lists of issued and finaled permits, going back to 2020, on the Building Safety page.
• Copies of permits and related records finalized before 2020 can be requested through a public records request.
• The city’s GIS Hub has a Parcel Information map and an as-built index.
• Building staff can estimate fees and answer questions at 619-441-1726.

Comparing the issued list with the finaled list helps you spot a permit that was issued but never finaled, which can hold up a sale.

Mobile home installations

Building Safety also inspects new mobile home installations, mobile home accessory structures and state-mandated mobile home park inspections.

For an accessory structure, the city asks for a permit application, a mobile home accessory structures form and two copies of plans or a standard plan approval, with the park manager’s signature required. Interior changes to the mobile home go through the State Department of Housing and Community Development.

A mobile home installation permit can typically be approved within about three weeks, according to the city.

Permit problems that come up when selling

• A permit was issued but never finaled.
• A garage conversion, patio enclosure or added bathroom has no permit at all.
• The finished work differs from approved plans.
• A solar or reroof permit was never closed out.

Options if your house has permit problems

You can apply to legalize the work, remove it or sell as-is. State disclosure rules apply either way; our guide to selling as-is with unpermitted work explains them, and the closing costs guide shows what you net under each choice. A cash buyer can close without waiting for plan check and without you paying for permit cleanup first.

Checklist before you list

• Search the city’s monthly issued and finaled permit lists for your address.
• Confirm each remodel, solar system and reroof has a final inspection.
• Request pre-2020 permit records through a public records request if needed.
• Gather plans and inspection sign-offs before you accept offers.
• Ask Building Safety at 619-441-1726 whether any permit is still open.

Common mistakes

• Assuming an owner-builder project did not need a permit.
• Covering framing or underground work before inspection.
• Letting a permit stay open after the work is done.
• Quoting square footage that includes unpermitted space.
