Permit types & fees

Building Permit

Verified

Carlsbad runs three application routes - online, by email and in person - and the choice is close to irreversible: once a submittal is determined hard copy it stays hard copy for the life of the permit. Construction waste reporting runs through a third-party platform that gates both the permit and the final inspection.

Requirements

TWO APPLICATION FORMS SPLIT BY OCCUPANCY: "Residential projects require a residential B-1 application form along with other supporting forms/documents. All non-residential/commercial projects require a commercial B-2 application form".
THE HARD-COPY DECISION IS EFFECTIVELY PERMANENT: "When minor permits are unavailable online, hard copy submittals are required. Once an application is determined hard copy, it will remain that way the life of the permit."
NO WALK-INS FOR A NEW SUBMITTAL: "Walk ins are not allowed for new/initial submittals. Appointments are required." And "Incomplete submittals are not accepted" - stated twice on the page.
REVIEW DOES NOT START UNTIL THE MONEY DOES: "For those that require plan check, reviews will not begin until fees are paid." On the in-person route the fees are due at the appointment itself: "Bring a form of payment and be ready to pay initial plan check fees."
THE PORTAL ACCOUNT IS NOT INSTANT: "You can expect an email confirmation within one to two business days confirming your online portal access." The city phrases it elsewhere as the city reviewing the request "and respond in a day or so."
PLAN CHECK HAS A ONE-YEAR LIFE: "The plan check process extends for one year from the date of submittal. All reviews not completed within one year will expire. In order to renew an application after expiration a new set of plans must be submitted with payment for the subsequent plan review. (CMC 18.04.035)"
A CONSTRUCTION WASTE MANAGEMENT PLAN COMES BEFORE THE PERMIT: "Applicants for qualifying projects must submit a Construction Waste Management Plan through Green Halo before a permit is issued."

Fee schedule

Fee type	Amount	Notes
Review (plan check) and permit fees	Typically based on square footage or construction valuation.	"Building collects Review (Plan Check) and Permit fees, which are typically based on square footage or construction valuation and are assessed per the city's Master Fee Schedule." The Master Fee Schedule was not opened for this record, so no amount is transcribed.
When fees fall due	Before review begins.	On the online and email routes, "city will email you when fees are due" after submission, and "For those that require plan check, reviews will not begin until fees are paid." On the in-person route they are due at the submittal appointment.
Development impact fees	Additional and separate.	"additional fees may apply depending on scope of work, including but not limited to development impact fees (water meter, sewer, drainage, traffic, etc.) and if other permits are required."
What the permit-ready ADU programme saves	Three to six months, and approximately $8,000-$16,000.

That is the city's own estimate of an avoided PRIVATE cost, not a city fee.
