What would you choose? SB9 vs. ADU vs. Home Addition?
Hello BiggerPockets Community!
I have a property that I purchased in LA county that has a ~12,500 sq/ft of flat land (12,500 Sq ft lot) with one existing primary residence (1200 Sq/Ft)
I hired a architect to design an ADU (3bed/2ba, 1200 Sq/ft) and Addition (3 bed/2 ba, 1200 sq/ft) to the main home.
My plan was to add a kitchen/kitchenette to the addition after the city signs off on everything and rent it out as it's own unit
But now that I think about it, if something happens in the addition (i.e, a fire) I could be held liable since that area was never permitted to be its own rental unit or have a kitchen. Secondly, what can that mean to any insurance claims. Third, the addition is will be constructed to the existing master bedroom that is currently occupied by tenants. The contractor will have to take down an exterior wall when they begin framing making the master bedroom inhabitable. If we put up a temporary wall during construction, the city inspector will question why there is a wall there; unless I can make the claim that it's currently being used by a tenant? Would they be ok with that?
So here are my questions for the wise and experienced BiggerPockets community:
1. Should I scrap plans for the addition and just focus on the ADU? This way everything is permitted and legit and I don't have to worry about the master bedroom being unavailable.
2. Should I split the lot (SB9) to get the most of out of the land? 4 legitimate units as opposed to 2.
3. If I build an ADU, can I split the lot later in the future or will I no longer be able to after the build of the ADU? (I don't have the capital to build 3 units at once)
4. Should I talk to the city to see if I can maintain a wall in the master bedroom during construction since it's being used by the tenant and take it down at the end when it's ready to be attached to the addition?
I've spent about $25K so far on designs, plan checks, permits etc. I don't have a permit to start construction yet but am not contemplating whether my original plan is the way to go.
I know this is a long post but I wanted to provide as much relevant information as I could and I truly appreciate everyone's time in helping me with this critical decision!! Cheers!

Here's what I found about SB9 and tenants in the past 3 years.
"Benefits homeowners NOT institutional investors. Recent amendments require a local agency to impose an owner occupancy requirement as a condition of a homeowner receiving a ministerial lot split. This bill also prohibits the development of small subdivisions and prohibits ministerial lot splits on adjacent parcels by the same individual to prevent investor speculation. In fact, allowing for more neighborhood scale housing in California’s communities actually curbs the market power of institutional investors. SB 9 prevents profiteers from evicting or displacing tenants by excluding properties where a tenant has resided in the past three years."
from SB 9: The California HOME Act | Focus
and here is info about RSO and properties built prior to 1978
"Q12. May SB 9 be used for properties with units covered by the City’s Rent
Stabilization Ordinance (RSO)?
The City’s RSO covers properties with two units or more where at least one of the units
was built prior to October 1, 1978. This includes properties with a single-family residence
built prior to this date and a second dwelling unit (e.g., main dwelling, ADU, or JADU).
Please consult LAHD’s webpage and associated FAQ on this topic. Demolishing or
withdrawing a unit covered by the RSO requires an Ellis Act withdrawal. RSO units are
considered withdrawn from the housing market if they are demolished or if the two units
are split into two one-unit parcels due to a subdivision. Properties with only one unit on a
parcel are not subject to the RSO.
A property owner may not seek a permit for a SB 9 Two Unit Development during the 15-
year period after RSO units have been demolished or withdrawn from the rental housing
market (Ellis Act). Therefore, an Ellis Act withdrawal will disqualify a site from being
eligible for a SB 9 Two Unit Development for a 15-year period from the date of withdrawal.
A property owner who has completed an Ellis Act withdrawal at their site may pursue an
SB 9 Urban Lot Split only if the units withdrawn from the RSO (via an Ellis Act withdrawal)
are not demolished or altered.
They have a small matrix showing scenarios and SB9 eligibility. Check it out here -
