CITY -OF SANTA ANA 2025 Single -Family Residential Mandatory Requirements S mmarng and Building Agency platforms, and plenums designed or constructed with materials other than sealed sheet metal, duct board or flelt� used to convey conditioned air. Building cavities and support platforms may contain ducts; ducts in compressed. • tailed in the e s n FOR PE MIT ISSUA Factory -Fabricated Duct Systems must comply with applicable requirements of UL 181 for duct c nstruction, connections, and § 150.0(m)2: closures; joints and seams of duct systems and their components must not be sealed with cloth ba k rubber adhesive duct tapes unless such tape is used in combination with mastic and draw bands. Field -Fabricated Duct Systems must comply with applicable requirements for: pressure -sensitive apes, ,'sealants, and other § 150.0(m)3: requirements specked for duct construction. Date: Backdraft Damper. Fan systems that exchange air between conditioned space and outdoors must have backdraft or automatic § 150.0(m)7: dampers. Gravity Ventilation Dampers. Gravity ventilating systems serving conditioned space must have either automatic or readily accessible, § 150.0(m)8: manually operated dampers in all openings to the outside, except combustion inlet and outlet air openings and elevator shaft vents. Protection of Insulation. Insulation must be protected from damage due to sunlight, moisture, equipment maintenance, and wind. § 150.0(m)9: Insulation exposed to weather must be suitable for outdoor service (e.g., protected by aluminum, sheet metal, painted canvas, or plastic cover). Cellular foam insulation must be protected as above or painted with a water retardant and solar radiation -resistant coating. Porous Inner Core Flex Duct. Flex ducts with porous inner cores must have a non -porous layer or air barrier between the inner core § 150.0(m)10: and outer vapor barrier. Duct System Sealing and Leakage Test. When space conditioning systems use forced air duct systems to supply conditioned air to an § 150.0(m)l 1: occupiable space, the ducts must be sealed and duct leakage tested, as confirmed through field verification and diagnostic testing, in accordance with Reference Residential Appendix RA3.1. Air Filtration. Space conditioning systems with ducts exceeding 10 feet and the supply side of ventilation systems must have MERV 13 or equivalent filters. Filters for space conditioning systems must have a two inch depth, or can be one inch if sized per Equation 150.0-A. § 150.0(m)12: Clean -filter pressure drop and labeling must meet the requirements in §150.0(m)12. Filters must be accessible for regular service. Filter racks or grilles must use gaskets, sealing, or other means to close gaps around the inserted filters and prevents air from bypassing the filter. ' Space Conditioning System Airflow Rate and Fan Efficacy. Space conditioning systems that use ducts to supply cooling must have a hole for the placement of a static pressure probe, or a permanently installed static pressure probe in the supply plenum. Airflow must be z 350 CFM per ton of nominal cooling capacity, and an air -handling unit fan efficacy 5 0.45 watts per CFM for gas furnace air § 150.0(m)13: handlers and _ 0.58 watts per CFM for all others. Small duct high velocity systems must provide an airflow z 250 CFM per ton of nominal cooling capacity, and an air -handling unit fan efficacy <_ 0.62 watts per CFM. Field verification testing is required in accordance with Reference Residential Appendix RA3,3.' \/nnNlefinn enA InAnnr Air Minlifv Requirements for Ventilation and Indoor Air Quality. All dwelling units shall meet the requirements of ASHRAE Standard 62.2, § 150.0(o)l: Ventilation and Acceptable Indoor Air Quality in Residential Buildings subject to the amendments specified in §150.0(o)l. ' Central Fan Integrated (CFI) Ventilation Systems. Continuous operation of CFI air handlers used in CFI systems is not a permissible § 150.0(o)l B: method to provide whole -dwelling unit ventilation airflow required per §150.0(o)l C. A motorized damper(s) shall be installed on the ventilation duct(s) that prevents all airflow through the space conditioning duct system when the damper(s) is closed and controlled per §150.0(o)l Biii&iv. CFI ventilation systems must have controls that track outdoor air ventilation run time, and either open or close the motorized damper(s) for compliance with §150.0 0 1 C. Whole -Dwelling Unit Mechanical Ventilation for Single -Family dwellings. Single-family dwellings shall have mechanical ventilation § 150.0(o)1C: specified in §150.0(o)1Ci and 150.0(o)1Civ.Single family detached dwelling units and attached dwelling units not sharing ceilings or floors with other dwelling units, occupiable spaces, public garages, or commercial spaces may reduce their required mechanical ventilation rates in accordance with §150.0(o)l Cii-iii.' Vertically attached dwelling units shall not reduce their minimum ventilation rates in accordance with §150.0 0 1Cii-iii. § 150.0(o)1G: Local Mechanical Exhaust. Kitchens and bathrooms shall have local mechanical exhaust; nonenclosed kitchens shall have demand - controlled exhaust system meeting requirements of §150.0(o)l Giii, enclosed kitchens and bathrooms shall either use demand - controlled as specified in §150.0(o)l Gill or continuous exhaust as specified in §150.0(o)l Giv. Airflow shall be measured by the installer per 150.0 0 1Gv, and rated for sound per §150.0(o)l GO. § 150.0(o)1H-J: Airflow Measurement, Sound Ratings, Label of Whole -Dwelling Unit Ventilation Systems. The airflow required per §150.0(o)1C shall be measured by using a flow hood, flow grid, or other airflow measuring device at the fan's inlet or outlet terminals/grilles per Reference Residential Appendix RA3.7. Whole -Dwelling unit ventilation systems shall be rated for sound per ASHRAE 62.2 §7.3 at no less than the minimum airflow rate required by §150.0(o)1C. Manual on -off switches must be labeled per §150.0 0 1J. Field Verification and Diagnostic Testing. Whole -Dwelling Unit ventilation airflow, vented range hood airflow and sound rating, and HR § 150.0(o)2: and ERV fan efficacy shall be verified in accordance with Reference Residential Appendix RA3.7. Vented range hoods shall be verified per Reference Residential Appendix RA3.7.4.3 to confirm if it is rated by HVI or AHAM to comply with the airflow rates and sound requirement per §150.0(o)l G Electric and Batte Energy Storage Ready: Battery Energy Storage System (BESS) Ready. All single-family residences that include one or two dwelling units, which a load § 150.0(s): serving entity provides with electrical service for the dwelling unit that is greater than 125 amps, shall meet at least one of the following: Either BESS-ready interconnection equipment with backed up capacity of 60 amps or more and four or more BESS supplied branch circuits in §150.0(s)2, or a dedicated raceway from the main service to a subpanel that supplies the branch circuits in § 150.0(s)2; at least four branch circuits must be identified and have their source collocated at a single panelboard suitable to be supplied by the BESS, \ICE
