Here's a great analysis of the relationship between ADUs, STRs, LTRs and city policies:

The hypothetical ban on STRs in ADUs has little effect on long-term housing supply (LTRsS) for several reasons. First, ADUs are simply not numerous to begin with. After that, the “positive” effect of banning STRs in ADUs is balanced out by the “negative” effects that such a ban would have on ADU production, as well as the fact that there is no guarantee STRs will be converted to LTRs.
Though your inputs may differ, it’s hard to find a defensible set of input parameters that produces a gain of more than 500 LTRs over a decade. Some defensible inputs show the ban would actually reduce the number of LTRs....
It seems odd that around the country, so much attention has been paid to the notion of reining in ADUs, as if the whole housing form has gotten dangerously out of control. While STRs have dramatically expanded their number in many cities, permitted ADUs have not.
Permitted ADUs are an rather rare form of development, and they have a lot of unique positive qualities. In cities like Portland and Santa Cruz, with booming markets and housing crises, ADUs are part of that elusive “missing middle” — kinds of development which satisfy the need to densify while they prevent repulsive megadevelopments. ADUs definitely aren’t the only solution cities need, but there probably should be more ADUs, not less.
However, cities can’t manage ADUs the same way they do bigger developments, because they are not usually created by professional developers. The homeowner-developers behind most ADUs are unprofessional, and that has good consequences as well as bad. ADU landlords and tenants frequently collaborate on things like child care, shopping, yard work, and other things that make life better, and would never appear in the professional property manager’s handbook.
Those positive effects come about because ADUs are so flexible in their use and informal in their management — which are exactly the same qualities that make ADUs suitable for use by small businesses, such graphic design offices or STRs.
If cities and citizens want to maximize the long-term housing benefits of ADUs, they may want to learn to love the chaos. With ADUs, it’s hard to ban the uses you don’t like, without also discouraging the ones you do.
