Split Zoning Philadelphia
Hey,
Would anyone know how split zoning works in Philly?
I have a 6650sf cmx 2.5 lot and and large RSA5 lot behind it. It’s my understanding you can add 20% to the CMX 2.5 lot by taking away from the RSA5 lot which is considered split zoning, but am I permitted to use that extra 20% of the RSA5 lot in my density calculations for CMX 2.5? If I can, can I build on it or does it have to remain open area?
Thanks!!!

Mayer,
You will need to combine the lots to have L&I approve what you're describing. These steps are how speculators add value to existing property. Do you have past experience in ground-up construction?
If you're looking to expand the build-able land on the CMX portion of the property it will be a multi-step process, that is doable, but will take time and money with risk that it is not approved.
1. Generate plot plan showing new commercial boundry lines
2. Submit plot plan to Philadelphia OPA.
3. If approved by OPA, submit the zoning variance to ZBA
4a. You will likely have to present this zoning variance to a neighborhood association
4b. Philadelphia ZBA would then review and take into account recommendations from the NA.
5. Submit for building permit
This process may take you at least 6 months, assuming there aren't steps along the way requiring response/revisions, and wouldn't include a building permit. Where is this property located anyway?
