Most remodeling projects that involve structural changes, electrical, or plumbing work require permits from the City of La Mesa. We handle the permitting process for you and make sure all work passes inspection. Skipping permits can cause serious problems when you try to sell your home.
A standard room addition usually takes 8 to 16 weeks depending on the scope and permit timelines. Larger or more complex projects can take longer. We'll give you a realistic timeline during the planning phase and keep you updated throughout construction.
In most cases, yes. California state law and La Mesa's local regulations allow ADUs on single-family residential lots. We'll evaluate your property, review setback and size requirements, and walk you through the approval process from start to finish.
We work with experienced designers and can manage the design phase for most remodeling projects. For larger additions or ADUs that require engineered plans, we coordinate with licensed architects and engineers so you don't have to juggle multiple contractors.
We serve La Mesa and the surrounding East County San Diego communities including El Cajon, Lemon Grove, Spring Valley, Santee, and more. If you're within about 20 miles of our University Ave location, we can likely take on your project.
