Plan Submittal and Plan Review
Most plan checks require three (3) sets of plans and two (2) sets of structural calculations (if applicable). Depending on the type of project, additional documents and information may be required. Note: All plans must large enough to be clearly legible in detail and print.

    • Once a set of plans are approved, a building permit is issued to allow for construction.  Construction activity generally must be completed within 180 days from the issuance of the permit.
    • The City may also engage the services of pre-approved outside inspectors for certain types of construction projects. 
    • At the conclusion of all construction activities, including inspections, a permit will be closed or finaled.
    • After the final inspection, the permit and plans are archived by the City and may be viewed over the counter.


What Agencies or  Departments will need to review my plans?

Depending on the scope of the project any or a combination thereof, of the government agencies listed below may be required to review and approve plans prior to any construction activity. 

    • City of South El Monte: Planning Division, Public Works Department, Industrial Waste Division and NPDES Division.
    • Los Angeles County: Fire Department, Health Department, and Public Works 
    • Other Agencies: Air Quality Management District (“AQMD”)

After submittal, plans will be routed to City’s building plan check consultant, the City’s Public Works Department, Industrial Waste and NPDES. 



How many sets of plans do I need to submit for plan checks?

The total number of copies to be submitted vary depending on the type of project.   

Generally, plans must include Architectural, Structural, Energy, Electrical, Plumbing and Mechanical drawings. These plans are to be stamped and wet signed by the design professional(s) responsible for the project. Some minor types of projects may not require an Architect or Engineer in the design. If not sure contact the Building & Safety Department.

For new commercial, residential also for new additions to commercial and residential three (3) full set of plans are required for building plan check. Once plans are approved, the City will keep first set, 2nd set will go to the owner or contractors, while the 3rd set will be routed to the Tax Assessor Office.

How long is a plan check and permit good for?

A plan check application submitted to the Building and Safety Division is good for 180 days from the date of plan check submittal. An extension maybe granted by submitting a written request with detailed explanation with the reason for the extension prior to the expiration date of the plan check.

Effective January 1, 2019 Assembly Bill (AB) 2913 adds a new Health and Safety Code Section 18938.6 to provide that a Building Permit can remain active so long as the work authorized by the permit was commenced within 12 months, and the work is not abandoned.  In addition, the building official may grant one or more extensions of time for periods of not more than 180 days per extension.  A permittee requesting such extensions must make the request in writing and demonstrate justifiable cause for the extension.
 
For residential building permits, permittees need not comply with building standards issued subsequent to permit issuance so long as the permit is not deemed expired for certain reasons.  Previously, a permit was deemed expired when work was not commenced within 180 days.  AB 2913 extends that period to 12 months.
