CITY F PALM DESERT DEPARTMENT OUILDINO & SAF TY Date: We have reviewed the following information regarding solar panel installation onbthe roof of the above referenced home: 1. Site Visit by a representative from our office under my supervision identifying specific interior and exterior site information including the condition of the existing roof system and the size, spacing, and condition of existing structural framing members. Information gathered during the site visit includes photographs, sketches, and verification forms. 2. Design drawings of the proposed PV System layout, including details to mount the new solar panels to the existing roof. Based on the above information, we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: According to the 2016 California Building Code section 3403A.4, if the weight of the panels does not exceed 10% of the total weight of the building, changes to the building to address seismic/wind lateral forces are not required. We have assumed the weight of the building to be 47461 Ibs and based on a panel weight of 1185 Ibs the solar system would increase the total weight by only 2.5%. As such changes to the existing building to address lateral forces are not required based on the current code. However, we have included calculations to determine that the panel connections only are structurally adequate due to lateral forces. A. Description of Residence: The existing residence is typical wood framing construction with clay tile roofing. All wood material utilized for the roof system is assumed to be Douglas Fir -Larch #2 or better with standard construction components and consists of the following: • Roof Section: Prefabricated trusses at 24" on center. Survey photos indicate that there was free access to visually inspect the size and condition of the roof members. B. Loading Criteria 11.02 PSF = Dead Load (roofing/framing) 2.59 PSF = Dead Load (solar panels/mounting hardware) 13.61 PSF = Total Dead Load 20 PSF = Roof Live Load (based on local requirements) Wind speed of 130 mph (based on Exposure Category C - the total area subject to wind uplift is` calculated for the Interior, Edge, and Corner Zones of the dwelling.) Page 1 ol2 vi m Page 2 of 2 C. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "EcoFasten Solar Installation Manual", which can be found on the EcoFasten Solar website (www.ecofastensolar.com). If during solar panel installation, the roof framing members appear unstable or deflect non -uniformly, our office should be notified before proceeding with the installation. 2. The solar panels are 11/2" thick and mounted 41/z" off the roof for a total height off the existing roof of 6". At no time will the panels be mounted higher than 6" above the existing plane of the roof. S. Maximum allowable, P ullout'A'erf d• rew (5/16" x 41/z") is 235 lbs/inch of penetration as identified in the National r Design SpifitionsNDS} q ; i"N rr�construction specifications for Douglas Fir -Larch.

Summary Based on the above evaluation, with appropriate panel anchors being utilized the roof system designed on will adequately support the additional loading imposed by the solar panels, if installed correctly. This evaluation is in conformance with the 2016 California Building Code, current industry standards and practices, and the information supplied to us at the time of this report.

OK 2015 IEBC Section 707.2 states: "Where addition or replacement of roofing or replacement of equipment results in additional dead loads, structural components supporting such reroofing or equipment shall comply with the gravity load requirements of the International Building Code requirements. EXCEPTION 1. Structural elements where the additional dead load from the roofing or equipment does not increase the force in the element by more than 5 percent." 2015 IRC Section AJ501.4 states: "The minimum design loads for the structure shall be the loads applicable at the time the building was constructed, provided that a dangerous condition is not created. Structural elements that are uncovered during the course of the alteration and that are found to be unsound or dangerous shall be made to comply with the applicable requirements of this code." 2015 IBC / 2016 CBC Section 3404A.3 states: "Any existing gravity load -carrying structural element for which an alteration causes an increase in design gravity load of more than 5 percent shall be strengthened, supplemented, replaced or otherwise altered as needed to carry the increased gravity load required by this code for new structures."

In an effort to enhance life safety within dwellings, CRC Sections R314.6, R315.2 and CBC 420.4 requires the retrofit of these alarms in existing dwellings when alterations, repairs or additions requiring a permit and exceeding $1,000 in value are made. Generally, the alarms must be hard wired (110 volt) with battery back-up and all alarms are to be interconnected. If the installation of the alarms will require the removal of wail or ceiling finishes or there is no access by means of attic, basement or crawl space, then alarms may be solely battery operated and not interconnected. Alarms must be installed in &HI of the following locations within the existing dwelling: • In all bedrooms (only require Smoke Alarms) Immediately outside of each separate bedroom (require Smoke and Carbon Monoxide Alarms) • In each story level of the dwelling, including basements and habitable attic rooms (require Smoke and Carbon Monoxide Alarms) And; • Shall be current within 10 years from the date of manufacture marked on the unit, or replaced if the date of manufacture cannot be determined. • Shall be equipped with a 10 year battery if a conventional ionization smoke alarm. These safety devices must be installed by the time a final inspection is requested for your project. l understand the above requirements and certify that we now have smoke alarms and carbon monoxide alarms installed that comply. We agree to comply with the CRC in regards to smoke alarms, carbon monoxide alarms. Signature of Owner Date ATTENTION OWNER - OCCUPANT: Signature of Tenant Date This is a Voluntary Smoke and Carbon Monoxide Alarm verification procedure. If you prefer a Building Inspector to perform the verification, you must arrange to have an adult present at the time of inspection. NO This Verification is only used when normal access to the interior of the dwelling by the City of Palm Desert Building Inspector is not achieved during the course of project construction. It is normally used for projects such as re -roofing, re -siding, patio covers, swimming pools and the like.
