Split your lot using SB 9

No, the two resulting lots must be roughly equal in size (between 60/40 and 50/50).

It depends on the home's rental history and your jurisdiction.
If the home has been owner occupied or vacant for the last three years, the house can be demolished in most jurisdictions. However, if it has been rented or leased to tenants at any point in the last three years, you may not demolish the house or change more than 25% of the exterior walls.
Some jurisdictions do not allow demolition of 25% or more for any units, regardless of current or former occupancy.

You can sell one of the two lots right away. If you want to sell the other lot too, you'll need to live on it for three years first.

Your property will be smaller following the split, which causes a slight drop in home value (usually around 10% for a 60/40 split).
The lot split won't affect property taxes, although you can request to have your property reevaluated following the split to see if you'll owe less.
SB 9 does not seem to affect a property's Prop 13 status, but it will reset when a lot is sold.

First we assess the feasibility of a lot split on your property with the numerous factors at-play, including, but lot limited to: Site conditions, jurisdictional roadblocks, and seeking approval with your lender (which must issue an approval). If everything checks out, we then coordinate all third-party specialists (e.g. civil engineer, surveyor, etc), fill out the required documentation, and submit the application on your behalf. We charge a baseline fee for our services, and all fees incurred during the subdivision process are passed along to you with no markup.

Like most SB 9 questions, it depends on your city. We charge a base fee for our labor, then pass applicable permitting, third-party specialist, and impact fees on to you with no mark-up.

Of course, but it's a lot harder than you might think! It involves hiring a number of specialists, preparing and submitting more than a dozen different documents, and lots of back-and-forth with your local planning department. Hiring Homestead to process your lot split application saves you lots of time and frustration.

Some cities have a more complex application and permitting process, which requires more work on our end. Our fees are relative to the difficulty of the process and our level of prior experience with the's city planning department.

If there is an outstanding mortgage on your property, you will need to get written permission from your lender in the form of a partial release of mortgage.
If your lender won't agree to a partial release, you can refinance your mortgage with a different lender. Keep in mind that your lease terms and interest rates may change as a result of the refinance.

Yes, you can split your lot if you have an ADU. However, the ADU will need to stay on the same lot as the existing house.

Yes, you can still use SB 9 on a former or current rental property. However, you may not demolish more than 25% of a house until it has been owner occupied or vacant for three years.

You can only use SB 9 to split a lot once. However, if you have a large property, you could subdivide your lot with a standard subdivision first, then use SB 9 to split one of the two resulting lots.

You would not be able to split both new lots with SB 9, because the same person (or anyone acting in concert with the same person) cannot use SB 9 to split adjacent properties.
