Why homeowners choose BluPlan Studio for permit & drafting
Getting an ADU permit in San Diego starts with the right drawings. BluPlan Studio prepares complete ADU permit packages for homeowners throughout San Diego County: floor plans, elevations, site plans, structural details, and the permit application itself, submitted directly to your building department. We handle every plan check comment until your permit is approved, and the same service covers additions, remodels, and garage conversions. A declined submission can push a construction start back by months, so everything we prepare is built to pass plan check the first time. Whether you designed your ADU with us, bought plans elsewhere, or need as-built drawings to document existing construction, we manage the entire permit process from document preparation to final approval. We work with building departments in San Diego, La Jolla, Chula Vista, Escondido, National City, El Cajon, and surrounding cities.

The ADU Permit Process in San Diego County
Each city in San Diego County runs its own ADU permit process, but the structure is similar everywhere: you submit a complete drawing package (site plan, floor plans, elevations, structural details, and energy compliance documents), the building department reviews it in one or more plan check cycles, and you receive your permit once every comment is resolved. Most delays happen when a package is incomplete or a plan check comment sits unanswered.
That is the part we take off your plate. We prepare the full ADU permit package for your specific jurisdiction, submit it, track its status, and respond to every plan check comment until the permit is issued. State ADU law also works in your favor: California requires cities to act on complete ADU applications within 60 days, and we make sure your application qualifies as complete from day one.
As-Built Drawings & Plans in San Diego
As-built drawings document a home's existing conditions: the accurate floor plan, dimensions, and construction of what stands on the property today. San Diego homeowners typically need them when remodeling a house that has no original plans on file, when legalizing unpermitted work like a garage conversion, or when a sale surfaces undocumented changes.
We measure your property in person and produce as-built plans that San Diego County building departments accept as the basis for permit applications. If your project starts with undocumented construction, as-builts are step one, and we handle the permit package that follows.
Frequently Asked Questions
Every ADU requires a building permit from your city's building department, which covers the structure, electrical, plumbing, and mechanical work. Depending on your property you may also need related approvals: a Coastal Development Permit in the Coastal Zone, school and utility fee processing, or fire department review. We identify exactly which approvals your property needs and handle all of them as one package.
We provide construction drawings for ADUs, additions, remodels, garage conversions, and new construction, including floor plans, elevations, sections, site plans, and structural details.
Permit timelines are set by each city's building department and vary by project type and workload. What we control is making sure your application is complete and accurate from the start, which reduces the correction cycles that cause most delays.
Costs depend on project scope, whether structural engineering is involved, and your city's submittal requirements. We provide a fixed, itemized quote during your free consultation so you know your full cost before committing.
Yes. Properties in the California Coastal Zone (including much of La Jolla, Pacific Beach, Ocean Beach, and Imperial Beach) may need a Coastal Development Permit in addition to the standard building permit. We prepare the documentation and coordinate the coastal review alongside your city permit.
Yes. As-built plans document your home's existing conditions and are required when you remodel without original plans, legalize unpermitted work, or sell a property with undocumented changes. We measure the property and produce accurate as-built drawings accepted by San Diego County building departments.
A site plan for permit typically includes property boundaries, existing structures, proposed additions or ADUs, setbacks, utility locations, drainage, and any grading information required by the building department. We prepare site plans to meet the specific requirements of each San Diego County jurisdiction.
