Testimonials

Monica Phillips, Home Owner

Working with LPL was the smoothest part of our remodel projects’s preparatory work. They worked efficiently via 100% remote meetings with our contractors and delivered plans on time (even early!), within budget, and which were approved in the first permitting submission. This was no small feat in our city, where multiple plan corrections are the norm. After a year of design, planning, and approvals, we’re about to start demo – only with LPL’s deliverables did my husband and I high-five and fist bump on completion bc they so vastly exceeded our TAT and quality expectations. Highly recommend.

Eugene Keane, Home Owner

I recently engaged LPL Consultants to do the structural design work including seismic for the remodel of my 100 year old home in CA. They were always responsive in providing advice when field adjustments were required allowing us to keep the project moving and meeting all city inspections. They were transparent and fair and simply a pleasure to work with.

Brian Sholder, Home Owner

We contracted LPL to do a roof structural design for the historic Washougal Grange. They were very responsive and easy to work with. We have also oused them for other smaller structural tasks on the project and they have provided timely drawings and claeifications. The ywere also helpful in dealing with the City to get permits issued

FAQs

What does a structural engineer do for a custom home?

A structural engineer designs the load-bearing system of your home — the beams, columns, shear walls, and foundation that keep it standing under gravity, wind, and seismic forces. For a custom home, we analyze your site conditions, architectural plans, and local code requirements to produce stamped structural drawings your contractor can build from and your building department will approve.

How long does structural engineering take for a permit submittal?

For a typical custom home or ADU, expect 3–5 weeks from kickoff to permit-ready drawings. Complex projects — hillside sites, multifamily, or projects requiring peer review — may take 6–10 weeks. We communicate timelines upfront and flag issues before they delay your permit.

Do I need a structural engineer or just a civil engineer?

For most residential construction — foundations, framing, shear walls, retaining walls — you need a licensed structural engineer (SE or PE with structural experience). A civil engineer handles site grading, utilities, and drainage. Many projects need both; we can coordinate with your civil team.

What states is LPL Consultants licensed in?

LPL Consultants holds active engineering licenses in California, Texas, Florida, and Washington. Each project is stamped by the licensed engineer of record for that state.

What types of projects does LPL work on?

We specialize in custom residential homes, ADUs, multifamily buildings (duplex through mid-rise), hillside and challenging terrain projects, and structural permit packages. Our clients include architects, general contractors, developers, and homeowners.
