About Gueridon Engineering

Gueridon Engineering is a civil engineering practice based in Glendale, California, serving residential, commercial, and public-works clients across greater Los Angeles.

We handle the civil side of getting a project from concept to permit: site design, grading and drainage, utility design, and coordination with the local agencies that review and approve the work — LADBS, LA County, and surrounding city building and planning departments. Our goal is to get your project through plan check with as few rounds of resubmittal as possible.

We work directly with homeowners, architects, developers, and contractors, tailoring the level of service to the project — a straightforward ADU grading plan gets the same attention to detail as a multi-parcel commercial site.

Frequently asked questions

Do you handle permits with LADBS, LA County, and local cities?

Yes. We prepare grading, drainage, and site civil plans for submittal through the LA Department of Building and Safety (LADBS), Los Angeles County Public Works, and the building and planning departments of surrounding cities such as Glendale, Burbank, and Pasadena. We track plan check comments and manage resubmittals through to approval.

What is the typical turnaround for a grading and drainage plan?

Turnaround depends on the site's slope and soils, scope of grading, and the reviewing agency's current plan check cycle — a small residential lot moves faster than a multi-parcel commercial site. We provide a project-specific schedule estimate after an initial review of your site and scope.

Do you work with individual homeowners, or only developers?

We work across the range of project types — from single-family homeowners doing an addition, ADU, or hillside remodel, to developers and general contractors on multi-unit residential and commercial projects.

What areas do you serve?

We're based in Glendale and serve the greater Los Angeles area, including the San Fernando Valley, San Gabriel Valley, and surrounding LA County communities.

How is pricing structured?

Because grading, drainage, and permitting scope varies site to site, we typically provide a fixed quote after an initial review of your project and its entitlement requirements.

Do you provide construction observation and plan stamping?

Plans are prepared and stamped by a licensed civil engineer as required for permit submittal and construction.

Are you insured and licensed in California?
