Know what your lot can do

Your free lot review shows:

  • What’s possible.

    One backyard unit, two, up to four, or a lot split, and which fits your budget best.

  • What it costs.

    Building, permits, and the ways to pay for it, like a home equity line.

  • What it’s worth after.

    The rent it could earn, or what it could sell for.

This is a full feasibility study: it shows what you can build and whether the numbers work. I usually charge $1,499 for it.

What a homeowner said

Kept their home and built two backyard units

“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.”

Questions homeowners ask me

How much does a backyard unit cost?

It depends on the size, your lot, and the finishes you pick, plus permits. Your free lot review 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 free lot review shows the options that fit you.

Can I build and sell for a profit?

It can be. Adding units 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 lot review shows whether the numbers work on your lot.
