Move From Coastal Property Check to Final Carlsbad Inspection Without Choosing the Wrong Permit Route
Carlsbad does not use one submission method for every project. Your permit may be filed through the online portal, emailed as an eligible minor submittal or delivered by appointment as a hard-copy application.
This guide shows how to choose that route, prepare the current B-1 or B-2 application, check coastal and zoning restrictions, pay review fees, answer corrections, request inspections before 2 p.m. and prove that the permit is actually closed.

Understand What the Portal Is Telling You
Protect the One-Year Application Deadline
Before permit issuance
The current B-1 and B-2 applications state that a building permit application expires when the permit has not been issued within one year from the original application date, unless an extension is granted.
Request an extension before expiration
Use Form B-25. If an application expires, a new filing may be required and the project can become subject to current fees and regulations.
Search Online Before Requesting Duplicate Building Plans
Search the city record portal
Use the address, APN or known permit number to locate available permits and public documents.
Check the permit dashboard
Online permits may show plan-check comments, invoices, inspections and status through the associated dashboard.
Visit the Development Services counter when needed
Building plans and permits are available for viewing during regular working hours at the Faraday Center.
Submit a duplicate-plan request
Use the city’s Request Copy Building Plans service and Form B-43/B-41 information when copies are required.
Allow for copyright authorization
California law can require written permission from the design professional and building owner before construction plans are duplicated.
Most retained plans
The city says most retained plans are for new construction permitted after 1980.
Remodel plans
Plans for residential remodels or additions are not typically retained.
Pre-incorporation buildings
Plans for structures built before July 16, 1952 may be held by San Diego County.
