General Contractor in Laguna Beach, CA
Siemonsma Construction is a licensed, bonded general contractor serving Laguna Beach, CA: custom homes, remodels and hillside construction.
Laguna Beach is one of the more demanding places in Orange County to build: steep lots, narrow streets, coastal rules and the city's own design review process. Siemonsma Construction is a general contractor based in nearby Newport Beach with more than 40 years of experience in new construction and custom remodels.
Our portfolio includes a hillside Spanish-style residence in Laguna Beach, which you can see on the projects page.
Design review comes first
Laguna Beach requires design review for most new homes and for many additions and exterior changes. The review considers issues such as neighborhood compatibility and the effect on neighbors' views, and it includes public notice so that neighbors can comment. Projects are commonly required to put up story poles that outline the proposed building on the site.
Design review happens before the building permit, so it shapes both the design and the schedule. It is led by the architect, and it helps to have a builder involved at that stage, because changes requested during review can affect structure and cost.
Hillside construction
Much of Laguna Beach is built on steep terrain. Hillside lots usually call for a geotechnical report, engineered foundations, retaining walls and careful drainage design. Streets in the hills are often narrow and winding, which limits the size of trucks and affects how concrete, lumber and equipment reach the site. These conditions are manageable, but they need to be planned for and priced from the beginning.
Coastal and fire requirements
Most of the city lies within California's Coastal Zone, so a coastal development permit can apply in addition to design review and the building permit. Large parts of Laguna Beach are also mapped as very high fire hazard severity zones, where the California Building Code requires ignition-resistant materials and construction methods for new buildings.

FAQ
Frequently Asked Questions
It is a city review of a project's design that takes place before a building permit is issued. It applies to most new homes and to many additions and exterior changes, considers issues such as neighborhood compatibility and neighbors' views, and gives neighbors the chance to comment. Your architect prepares and presents the application.
Yes. It is a separate step ahead of plan check and the building permit, and the outcome can require revisions to the design. It should be built into the project schedule from the start and not treated as a formality.
The ground conditions drive the design. A geotechnical engineer investigates the soils, a structural engineer designs the foundation and retaining walls to suit, and drainage has to be handled carefully. Access for equipment and deliveries is usually tighter than on a flat lot, which affects how the work is sequenced.
