I haven't invested in the Lease w/Option to Purchase field, so take this as a gut feeling.I would stipulate that if the tenant/purchaser plans on making any improvements for which your city requires permits, that the tenant/purchaser go through the permit+inspection process. 

Am I permitted to search and contact them on BP ?

Your agreement with the screening service will stipulate that you are not permitted to distribute copies of the reports to anybody. 

Then he said did I pull all the rental permits, electrical and hvac permits.

Can't find a permit on the HVAC but it can't be the original either but looks worn.

@Ruchi Patel --The Green Card is handled by the NJ Dept. of Community Affairs (DCA), which is a state level agency.From a City standpoint, you'll have a number of hurdles, both zoning and building related.The property's zoning designation may not permit a 3-family use as of right (per the current zoning code), so in order for them to allow a conditional 3-family use, you'd need a variance.If they grant the variance (which is a process in and of itself), you will likely face challenges from a building standpoint as well as they may require you to bring certain elements of the building up to code (i.e., fire suppression / sprinkler system).

@Jared Watson, how do you manage the challenges with the City of Austin Permit and inspection system?

That individual might be more familiar with larger building codes and permitting needed for bigger renovations.  

I was in the process of renovating an old house and got shut down by the county for not having a building permit.

For anyone in Chicago, what kind of permits (if any) are necessary?
