Interpretation of Fee Calculation
Interpretation of Fee Calculation
- The floor area of the proposed work is measured to the outer face of exterior walls and to the centre line of party walls or demising walls. For interior alterations or renovations, the area of proposed work is the actual space receiving the work. Mechanical penthouses and floors, mezzanines, lofts, habitable attics and balconies are to be included in all floor area calculations. Except for interconnected floor spaces, no deductions are made for openings within the floor area. Unfinished basements and attached garages for single detached, semi-detached, duplex and townhouse dwellings are not included in the floor area. Fireplaces, porches, decks etc. are included in the permit fee for single detached, semi-detached, duplex and townhouse dwellings. Where interior alterations and renovations require relocation of sprinkler heads or fire alarm components, no additional charge is applicable. Ceilings are included in both new shell and finished (partitioned) buildings. The Service Index for ceiling applies only when alterations occur in existing buildings. Minor alterations to existing ceilings to accommodate lighting or HVAC improvements are not chargeable. Where demolition of partitions or alteration to existing ceilings is a part of an alteration or renovations permit, no additional charge is applicable. Corridors, lobbies, washrooms, lounges, etc. are to be included and classified according to the major classification for the floor area on which they are located.
- The occupancy categories in the Schedule correspond with the major occupancy classifications in the Ontario Building Code. For mixed occupancy floor areas, the Service Index for each of the applicable occupancy categories may be used, except where an occupancy category is less than 10 per cent of the floor area.
- In the case of an incomplete application, if the preliminary estimate of the fees required is more than $20,000, then the deposit shall be the greater of $20,000 or an amount equal to 60 per cent of the estimated full Building Permit fees required
