Rooftop Grease Design and Installation Criteria
Introduction:
Due to high potential of spillage and runoff from rooftop ventilation and exhaust fans and the Fats, Oils and Grease
(F.O.G.) they produce, The Irvine Company, Retail Properties group has created the following criteria. This
criterion has been created to significantly reduce the exposure of F.O.G. on the Landlord’s roofing systems and
exposure to runoff into the rooftop storm drain systems. F.O.G. is acidic in nature and causes rapid deterioration of
roofing materials. Additionally, runoff of F.O.G. into the storm drain systems puts both the Tenant and Landlord at
significant risk with Governmental agencies that monitor water quality issues.
Equipment:
Rooftop equipment designed by the Tenant shall conform to all regulatory and statutory requirements set forth by
all municipal reviewing agencies. In addition, the following requirements shall also be adhered to in the design of
the Tenant’s rooftop exhaust and ventilation systems:
1. Rooftop exhaust systems shall be designed to accommodate all code requirements, but shall not be over
designed as to discharge extraordinary amounts of F.O.G. onto the surrounding roof system. Exhaust
velocities shall be maintained to manufacturer specifications to adequately capture all discharge materials.
2. All rooftop equipment shall provide rainproof capture and collection systems for any and all F.O.G.
discharge.
3. Rooftop exhaust and ventilation equipment shall be installed in compliance with Landlord’s rooftop
equipment installation details set forth elsewhere in this criterion.
Although, the design and engineering of rooftop exhaust and ventilation equipment is regulated through municipal
code, The Irvine Company, Retail Properties has found the following companies to provide superior grease
containment and capture to other manufacturers and require that Tenants utilize one of these manufacturers.

Alternative manufacturers may be utilized only if the equipment specifications are equal to or exceed those provided
by the aforementioned manufacturers and approved in writing by Landlord. The Landlord does not warrant, nor
assumes any liability for the products or performance of the aforementioned companies.

Maintenance:
Tenants are required to maintain all grease producing rooftop equipment to eliminate the possibility of runoff of
F.O.G. onto Landlord’s roof systems and into roof drains. Maintenance shall be performed by a Landlord approved
company licensed to inspect and maintain exhaust systems and shall occur a minimum of 6 times annually or more
frequently as required by governing agencies and shall consist of the entire system from the rooftop exhaust and
ventilation units all shafts leading down to the source equipment and any and all filtration systems associated with
this equipment. Landlord may, at its discretion, provide rooftop exhaust maintenance services as a Common Area
Expense and Tenant shall be responsible for its pro-rata share.
Landlord’s Plan Review:
During the Tenants design and engineering process, all mechanical drawings showing any and all rooftop exhaust
and ventilation equipment shall be submitted to Landlord for review and comment through Landlord’s proprietary
mechanical consultant. Tenant shall comply with all of Landlord’s comments and incorporate comments into
Tenant’s drawings. Tenant shall pay all costs associated with Landlord’s review of tenant’s plans estimated as
follows:
xQuick Serve Restaurant $500 per review.
xFull Service Restaurant $850 per review.
xField Inspection reports $125 per hour with a 2-hour minimum.
