Who the screen is for

Owners who live there

You want to know whether an urban lot split is even a conversation, or whether a second unit on the same parcel is the honest first study.

Buyers under contract

You need the questions a seller’s flyer skipped: tenancy, title, slope, and whether a lot split would carry an occupancy affidavit you cannot sign.

Advisors and agents

You can open a file for a client without telling them the house is eligible. The results page names a pathway to review, not a determination.

What you can learn for free

Whether the address is a California street address we can open a file on.
Which pathway matches the ownership and occupancy answers you give.
The facts still missing: APN, zoning, area, hazards, title, and survey.
A clear label when you use a scripted demo, so it is not mistaken for a live parcel.

What this site will not say

That you are eligible, approved, or guaranteed a second parcel.
A lot size, zone name, or assessor number we did not receive from a connected source.
A resale price, rent, or investor return.
That a statutory timing discussion means your application is complete.

Development pathways

Urban lot split

A two-parcel idea that can include an owner-occupancy affidavit and a survey.

Two-unit development

A duplex-style path that is not the same application as a lot split.

ADU / JADU

Often the simpler capacity question when a split is a poor fit.

Conventional subdivision

A longer map process when SB 9 is not the route.

Development review

A written look at what is still unknown before anyone files.

What a real review has to check

Parcel size and shape
Single-family zoning context
Lot geometry
Hazard and environmental constraints
Existing home and tenant history
Ownership and occupancy path
Title, easements, and access
Utilities and servicing

This free screen does not complete those checks. Where a data feed is not connected, we say so.

Free preliminary screen

Address, ownership questions, and a pathway to discuss. Not a determination.

Stage 1 · Verified feasibility

$950

Review and project setup. Not a guarantee of approval, financing, or resale value.

Later stages

Stage 2 survey, title, city filing, and consultants are quoted and passed through at cost. Stage 3 delivery fees are disclosed in a written agreement.

Questions

Does a California address mean my property qualifies?

No. City or state location is not eligibility. SB 9 still depends on the parcel, the zoning context, tenancy history, hazards, title, and the local objective standards applied to a complete application.

Is the 60-day clock a guarantee?

For eligible SB 9 projects, California law generally requires local agencies to approve or deny a complete application within 60 days. Final eligibility and approval remain subject to statutory requirements, complete application materials, and applicable local objective standards.

Can an investor use an SB 9 lot split?

Urban lot split pathways can include owner-occupancy requirements. We assess your ownership and occupancy scenario before recommending a route. A rental profile is a reason to compare duplex, ADU, and other routes before anyone files a lot split.

What does the $950 cover?

A verified feasibility review and project setup: a person checks the facts this screen cannot see and writes up a pathway. It is not a survey, title policy, city filing fee, or construction budget.

Will you invent an APN, zone, or lot size?

No. If a parcel feed is not connected, those fields stay blank. Demo addresses are labeled as scripted profiles, not live assessor records.

What is the difference between a lot split and a two-unit project?

A lot split asks the city or county to create a second parcel. A two-unit project keeps one parcel and studies a second home on it. They are different applications, different owner-occupancy questions, and different costs.

Do you file with the city?

Not inside the free screen or the $950 review. Filing, if you want it later, is a separate written scope after you have a survey, title, and a complete application checklist.

Which addresses can I try?

Any California street address. Out-of-state addresses and PO boxes are refused. The labeled demos are 123 Example Street in Los Angeles, 456 Rental Avenue in Pasadena, 789 Hillside Drive in Glendale, and 101 Sample Road in Long Beach.

Start with the address, not a conclusion

We will not tell you that you qualify because the property is in California.
