One studio. Design, drawings, and permits, done.
Most homeowners work with a designer, a drafter, and a permit runner separately. We handle all three under one roof.

View allADU Design
BluPlan Studio designs ADUs for homeowners across San Diego County, from detached backyard units on single-family lots to garage conversions and junior ADUs inside existing homes. We draw the floor plans, produce a complete set of permit-ready construction drawings, and manage the entire permitting process with your local building department. Whether you want to add a rental unit for income, house a family member, or make use of underutilized space, we'll tell you exactly what's buildable on your property under current San Diego County building code. Start with a free consultation. We've worked with building departments in San Diego, La Jolla, Chula Vista, Escondido, National City, and El Cajon, and know how each city handles ADU applications.
Garage Conversion
California makes garage conversion one of the most straightforward ways to add living space to your property. Under state ADU law, you can convert an attached or detached garage, one-car or two-car, into a rental unit, guest suite, home office, or multigenerational living space without replacing the parking. BluPlan Studio prepares garage conversion plans and full permit drawings for San Diego County homeowners, handling every step from floor plan design to building department submittal. We've designed garage conversions throughout San Diego, La Jolla, Chula Vista, Escondido, National City, and El Cajon. If you're not sure whether your garage qualifies or what the conversion process involves, start with a free consultation. We'll review your property and give you a straight answer.
Home Remodel
Most remodels that touch plumbing, electrical, or load-bearing walls require permit drawings, and that's where BluPlan Studio comes in. We prepare remodel plans and construction documents for kitchen renovations, bathroom updates, open-concept wall removals, and whole-home renovations throughout San Diego County. Our drawings cover everything the building department needs: floor plans, demolition plans, elevations, and structural details. We handle the permit submittal and manage plan check responses so your contractor can get to work without delays. We've prepared remodel plans for homes in San Diego, La Jolla, Chula Vista, Escondido, National City, and El Cajon, from 1950s ranch houses to newer construction. Start with a free consultation to find out what your project needs.
Home Addition
Running out of room in your home? BluPlan Studio designs room additions, second story additions, and structural expansions for homeowners throughout San Diego County. We draw complete home addition plans (floor plans, elevations, structural drawings, and foundation details) and coordinate with your structural engineer to make sure everything is built to code. We handle the full permit process, from application preparation to plan check responses, so you're not chasing the building department on your own. Whether you need a master bedroom addition, a family room extension, or a full second story, we've worked on additions throughout San Diego, La Jolla, Chula Vista, Escondido, National City, and El Cajon. Contact us for a free consultation. We'll tell you what's possible on your lot.
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 all permits before construction starts, responding to 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.
Unpermitted Work Legalization
Unpermitted construction is everywhere in San Diego County: garages converted to bedrooms decades ago, granny flats built without drawings, additions that never saw a plan checker. If you own one of these spaces, it is a quiet liability. It complicates a sale, it may void insurance coverage for that part of the home, and a single complaint can turn it into a code enforcement case. BluPlan Studio legalizes unpermitted work for homeowners throughout San Diego County. We document the existing construction with as-built drawings, design the corrections needed to meet current code, and submit the permit package to your city, handling every plan check comment until the space is approved. Whether you inherited the problem when you bought the home or built the space yourself, the path to making it legal is more straightforward than most homeowners expect. Start with a free consultation and we will check your property's permit history with the city.
