How to start RUBS on my Los Angeles fourplex

[Rajesh M.]

4 Plex in Los Angeles City, which is part of LARSO rent control.

I have a vacancy in one of the unit - can i start with implementing RUBS with just one unit. Am hoping that eventually with turnover i can some day get to all 4 units on RUBS - given the high cost of water, and no ability to increase rent for almost 2 years now. 

1. Any RUBS providers that you recommend? How much do they cost?

2. Can I implement it myself?

3. Any general ideas/feedback/lessons learnt from this experienced gang here - on how to approach it?
