Property Evaluation
Send us your address. A licensed architect studies your zoning, setbacks and California's newest housing laws, then records a 10-minute video walking you through every option, from a backyard ADU to a cluster of starter homes.
How it works
Fill out the short form with your property address and what you are hoping to build. No call or meeting needed.
An architect reviews zoning, lot size, setbacks, overlays and which state housing laws apply.
A personal screen-recorded walk-through of your options that you can rewatch and share with family or your lender.
Your video includes a link to book a follow-up with the architect, so you can ask questions and plan next steps.

Here is what a property feasibility video looks like: real zoning, real options, explained in plain English.
Possibilities
Pick the type of property that sounds like yours. Rules vary by city, and your evaluation confirms exactly what applies to your address.
Up to 4+ homes
Most California single-family lots can add an ADU and a junior ADU, and many can also use SB 9 to split the lot or build a duplex.
A separate small home in the yard. Cities must allow at least 800 sq ft, and many allow up to 1,200 sq ft.
A compact unit of up to 500 sq ft carved out of your existing house, perfect for family or a renter.
Turn an existing garage into a home, often the fastest and most affordable way to add a unit.
Split one lot into two, or build two homes on each, for up to four homes where your lot qualifies.
Up to 10 starter homes

Thanks to SB 1123, an empty lot zoned for one house (up to 1.5 acres) can now be divided into as many as 10 small lots, each with its own home for sale.
Small detached or attached homes on their own lots, sized for first-time buyers.
Approved by city staff within 60 days, with no public hearing and no CEQA review.
Where your city allows it, ADUs can be added and don't count toward the 10-home limit.
SB 1123 is for empty lots. If there's a house today, SB 9 and ADUs may be the better path.
Up to 10 homes, or up to 8 ADUs

On land zoned for apartments, SB 684 lets you create up to 10 for-sale starter homes. Existing apartment buildings can often add backyard ADUs instead.
Split a multifamily lot under 5 acres into up to 10 lots, each with a home you can sell.
Lots with existing apartments can add up to 8 detached ADUs, depending on how many units are there today.
Unused storage rooms, attics or garages inside the building can become new homes.
Need more than 10 homes? We also design and entitle larger multifamily projects.
Starter homes
Two California laws that make it much easier to build small groups of starter homes for sale.
SB 684 · in effect since 2024
The short version: if your lot is zoned for apartments and is under 5 acres, you can split it into as many as 10 lots and build up to 10 homes, each on its own piece of land you can sell.
SB 1123 · in effect since July 2025
The short version: an empty lot zoned for a single house, up to 1.5 acres, can now become as many as 10 starter homes using the same fast approval.
Neither law applies in very high fire hazard zones, on farmland or wetlands, or where it would displace existing tenants. This is a plain-English summary, not legal advice; your evaluation checks the details for your property.
