Difficult to give you a realistic Dollar Per SF for construction as it's heavily dependent upon costs of permits, utility connections, etc.

I put an offer on a triplex in south philadelphia that needs rehab. the zoning turned out to be RSA (SFH) not RM1(multifamily) but they have city permits for triplex and is currently rented.

I looked up the permits with the city and there are none related to fire damage (although their records only go back to 2001).

I went to city to pull permits for renovation, I came to know that the current zoning is Single family.As the utilities are not there on the property for more than six months, the City saysit lost its grandfather clause as Multi family.Through attorney, I have applied for variance to continue as Multi.I have the city hall meeting on October 1st.I would appreciate if any one has any advice on how to present at the city hall.ThanksTSReddy

In order to do the work, the plumber would need to get a work permit, and the plumber said it takes a few months to get a work permit these days!  

Call the county permitting department  and see when they were built.

My guess would be that the addition of the basement bedrooms was not even properly permitted.

I also have a friend with me (if possible); if not, I make sure the neighbors know I'm over there & I ask them to pop over as time permits. 

No pets are permitted on the premise without prior written consent of the Landlord.

All contracts, options, or other devices not based upon a substantial consideration, or that are otherwise employed to permit an unlicensed person to sell, lease, or let real estate, the beneficial title to which has not, in good faith, passed to such party for a substantial consideration, are hereby declared void and ineffective in all cases, suits, or proceedings had or taken under this chapter; however, this section shall not apply to irrevocable gifts, to unconditional contracts to purchase, or to options based upon a substantial consideration actually paid and not subject to any agreements to return or right of return reserved.So i looked up the statute which i posted above and it seems that the legality can really depend on how a person is perceiving the the property that is being wholesaled.
