I run ADU projects for San Diego homeowners, from the free lot check to move in.

Most owners know the yard could be worth more, but not what the rules allow, what it would earn, or who to call first. I make the plan, get the permits, and bring my architect and my licensed general contractor. One ADU, two, or up to a fourplex, and the rent, the space, or the value that comes with it.

Built: Two ADUs added. The main house and both ADUs are now rented.

What fits in your backyard

The gray house is yours. The orange ones are the new ADUs, drawn to scale.

One ADU

Up to 1,200 sq ft, two stories where your city allows it. An ADU of 750 sq ft or less pays no impact fees.

Fits: Parents or grown kids with their own front door, or one rental.

Two ADUs

Two separate buildings, 800 sq ft each, on every single family lot from January 1, 2027. Your house plus two ADUs is a triplex.

Fits: Income in retirement, or one for family and one to rent.

Four units or more

On larger lots, a lot split under SB 9 or the City of San Diego bonus program near transit can reach four to six units.

Fits: Owners who want to build value and go bigger.

Know what your lot can do

No plan: you do not know where to start, what it costs, or who to call first.
Out of pocket: you think it all has to come from your savings. Most of the time it does not.

What I do for you:

Free lot check.
A short call about your goal, then I look up your zoning and walk your lot with you.
Feasibility study.
If it makes sense: every option that fits your lot, as drawings, with the fees, the cost, the rent, and the value after.
The whole project.
My architect, the permits, my licensed general contractor at the pricing I get, and my checks at every stage, until you move in or rent it out.

The call and the walkthrough are free. You decide on the study after.

Text your address, or just your cross streets. I usually reply within minutes.

You will know if it makes sense before you spend anything.

What a homeowner said

Kept their home and built two ADUs

“Our plan was to sell our house and buy a duplex. Gio convinced us to keep the house and build two units in the back instead, and he knew exactly who to bring in to build them. Now we rent out all three, including the main house, and we finally bought our dream home in La Jolla.”

How it works

1Free lot check. A call, then a walkthrough of your lot.
2Study and plans. Every option as drawings, then my architect draws the plans and you get the full cost, permits included.
3Build. My licensed general contractor builds it and I check every stage. Then you rent it, move family in, or sell.

Questions homeowners ask me

How much does an ADU (backyard unit) cost?

It depends on the size, your lot, and the finishes you pick, plus permits. Your feasibility study shows the cost for your lot.

Do I need cash to build?

Usually not. You can use a home equity line of credit, which is a loan against the value you already own in your home. Your feasibility study shows the options that fit you.

Can I build and sell for a profit?

It can be. Adding ADUs turns your house into a duplex, triplex, or fourplex, and that can sell for more than the house plus what you spent to build. Your feasibility study shows whether the numbers work on your lot.

Why not just hire a contractor?

I work with licensed contractors on every project. The question is who does the work that comes before them. Checking what the city will approve, and whether it is the right thing to build, is not the contractor's job. Someone has to check the work against the plans and the permit at every stage; on my projects, that is me. And contractors give their best pricing to the people who bring them steady work, which is what your project gets.

What changes in 2027?

Two ADUs on one lot instead of one, and lower impact fees on larger ADUs. The design and the feasibility study can start now. Only the permit application waits for January 1.
