Detached ADUs, garage conversions, attached units and JADUs — designed, permitted and built by Laguna Bay Developing. Licensed, bonded and insured, CA License 1072840.
A designer who never speaks to the engineer. A plan check that comes back a third time. A contractor who finds out about the setback after the forms are already set. The homeowner ends up carrying messages between four companies that have never worked together.
Laguna Bay Developing runs the whole thing under one contract: feasibility on your lot, drawings, structural coordination, the city, and the build itself. One company is accountable — including when something has to change mid-project.
David and one supervisor on your project — not a call center and a rotating cast of subs.
Design, permits and construction sit in the same agreement, so nobody can point at anybody else.
You see what is in the number before anything is signed — and what is deliberately not.
Five stages, in this order, on every ADU we build. You always know which one you are in and what has to happen to reach the next.
We walk the lot, talk through how you will use the space and what the budget really is, and tell you what your property can realistically support.
Custom plans drawn around your lot, setbacks and access — not pulled off a catalog shelf. Structural coordination happens here, not later.
We prepare the submittal and carry it through plan check with your city, including corrections, until the permit is issued.
Site work and foundation, framing, roofing and exterior, electrical, plumbing and HVAC, then the full interior build-out and finishes.
We close out city inspections, walk the punch list with you, and hand over a finished unit that is ready to live in or rent.
Everything below is managed by us and covered by the same contract. Nothing on this list is your job to chase.
Setbacks, easements, utility locations, access for equipment — what your lot will actually allow before you spend money on drawings.
Full-service planning and design, drawn for your property and the way the unit will be used day to day.
We prepare the submittal, manage plan check with your city and handle corrections through to an issued permit.
The structural work, weatherproofing, windows, doors and siding — built to the drawings that were approved.
Installation, utility connections and inspections — including the panel and sewer questions that surprise most homeowners.
Insulation, drywall, cabinetry, countertops, flooring, tile, fixtures and paint — finished to the level you selected, not a builder default.
One supervisor, one schedule, clear timelines and dedicated supervision from demo to certificate — with weekly updates you do not have to ask for.
Most Orange County homeowners land in one of these six. We will tell you at the consultation which ones your lot and your city actually allow.
The efficient option: a studio or single bedroom with a full kitchen and bathroom. Fits a standard Orange County backyard, keeps site work and utility runs simple, and is usually the fastest route to a finished unit.
The most requested size. Real separation between living and sleeping areas, in-unit laundry, and enough room that a parent or a long-term tenant is not living in one space. Balances build cost against rentability.
Two bedrooms, a full kitchen, laundry, storage and a proper living area — an independent home on your lot. For multi-generational living, or a rental you intend to hold for a long time.
Shares a wall with the main house but has its own entrance, kitchen and bath. Often the cheaper path when utilities are already on that side of the building and the yard is worth keeping.
Converts an existing footprint instead of building a new one — usually the least expensive and least disruptive route to a permitted unit. The work is in insulation, egress, plumbing and bringing it up to code.
Builds up rather than out when the yard is tight or the lot coverage is already maxed. Needs a structural look at the existing garage first — that assessment is part of the consultation.
Every property is different. We design around your lot, your setbacks, where the sun lands, where the sewer runs, and how the unit will actually be used — a rental, an office, a place for a parent.
Design and construction sit with the same company, so the drawings are made by people who will have to build them.
Several California cities keep a library of pre-approved ADU plans that skip most of plan check. When one fits your lot, it can save weeks.
We check whether your city runs such a program and whether a standard plan genuinely suits your property — and we will say so plainly when it does not.
Nobody can price an ADU over the phone honestly. These are the six things that move the number on an Orange County lot — and what we put in writing once we have seen yours.
Square footage, number of bedrooms, and how many wet walls the plan needs. Two bathrooms cost more than two bedrooms.
Slope, soil, drainage, trees, and whether a machine can physically reach the back of the lot. This is the line item that surprises people.
Distance to the sewer connection, water line, and whether your electrical panel has to be upgraded to carry a second dwelling.
Plan check, permit and impact fees differ from city to city inside Orange County — and so does how long plan check takes.
Cabinetry, counters, tile, flooring and fixtures. The same floor plan can differ by a wide margin on selections alone.
Converting an existing garage removes foundation and framing from the scope, which usually makes it the cheaper option.
Laguna Bay Developing is a building and architectural design firm based in Newport Beach. Twenty-plus years of California construction, more than 500 projects delivered, and a third generation of builders behind it — the family started building in Eastern Europe in the mid-1950s.
Most ADU companies are brokers: they sell you a unit and subcontract every part of it out. We are a contractor. David, the owner, is on the job — the reason the same phrase keeps appearing in our reviews is that people can reach him and he shows up.
Licensed, bonded and insured, with a workmanship warranty on what we build. That is the protection you are paying for when you choose a licensed contractor over the cheapest bid on your street.

“I am so grateful to have found a general contractor I can trust. I've had the pleasure of speaking with their project management team and they are always available, able, and eager to answer any questions. I am so glad that my home construction was handled in such a responsible way — I would recommend Laguna Bay Developing to anyone!”
“We needed our back deck removed and replaced with pavers. We saw representatives from a few companies who talked to us about the work and gave us quotes. We wisely chose Laguna Bay Developing because their quote was competitive and they laid out in detail what they would be doing for us. The whole project was a pleasure.”
“Their service and creativity is absolutely amazing. The best part is that they were very easy to communicate with and really listened to my needs and wants. Laguna Bay Developing are highly professional in what they do, especially with the details they provide prior and during the project.”
