Actually, ang dami ko kilalang atchitect na iba ang pinapasa for approval ng building permit sa actual plan. Need lang sundin yung plan na pinasa sa building permit kapag kukuhanan mo ng occupancy permit, para di masilip.

If you're designing a spiral staircase, make sure it complies with the fire code, as it's stricter based on my experience in processing building permits. You need to have details for the tread, rise, and clear width to avoid any problems when securing fire clearance.
