How they are structured depends on municipality. Right now in SF its apparently set at 3.6%. Imo CPI is hardly relevant here, what is relevant is wage growth and typically thats always lagged behind. SF interestingly has stated going forward minimum wages will be based on some cpi calculation. Realistically if you applied rent control over the entire bay area any concerns regarding its ability to disadvantage building is moot at that point. The true limiting factor is probably a combination of zoning as well as onerous permitting and review processes. People in rent control units do get developed upon, they often readily accept buy out offers for example that are a rounding error for multimilliondollar apartment development projects. I believe redevelopment or renovation would count as just cause to evict but ianal.
