Even though CalHFA’s ADU grant program ($40,000 to reimburse pre-development and non-recurring closing costs) has been fully subscribed, this massive list includes participating lenders and special financers! https://www.calhfa.ca.gov/adu/ADU-lenders.pdf

Sarah Deeds Deeds Design regarding your new ~440sf ADU with conditioned crawlspace, are these the main systems-related topics right now? 1) minimal kitchen range hood that's quiet; 2) ducted mini-split heat pump with air handler in crawlspace; and 3) latest advice on ERVs
Sarah Deeds Deeds Design , a bummer about using a kitchen exhaust fan is that the airflow req. are much higher—300CFM (vs for range hood: 160CFM for ADU<750 sq.ft). The Toblino that Dan shared is only .5 sones at working speed of 100CFM so this meets the noise req. even though it's 7 sones at 340CFM (see bottom of this doc: https://storage904.cdn-immedia.net/sites/default/files/elica_ss_2023_to…). From T24 compliance manual "The Energy Code requires verification that range hoods are HVI or AHAM-certified to provide at least one speed setting at which they can deliver at least 100 CFM at a noise level of 3 sones or less."
Also for microwave/hood combo check out HVI Certified Products Directory (https://www.hvi.org/hvi-certified-products-directory/section-i-complete…). 1) under Product Category filter by kitchen range hoods; 2) under Subcategory filter by microwave; then 3) click on "Model" column to consolidate ratings for the same model at different flow rates. Find models with a high setting ≥160CFM that also have a lower setting ≥100CFM that is ≤3 sone req. These ones work: IKEA 004.621.66 https://www.ikea.com/us/en/p/medelniva-over-the-range-microwave-black-s… - IKEA 204.621.65 https://www.ikea.com/us/en/p/uppseende-over-the-range-convection-microw… - other IKEA products, Blomberg, Midea, Electrolux etc. The trick I think is to find a product that has offers a lower setting around 100-120CFM; then it pretty much guaranteed will be <3 sones at that lower setting

From City of Carlsbad Inclusionary Zoning Bonus - "One way that developers of single family homes can comply with the city’s inclusionary housing ordinance is by constructing ADUs that have a deed restriction. The deed restriction lasts for a period of 55 years, and requires that rent for the ADU be restricted to a low income level and that tenants be income qualified. The city’s inclusionary housing ordinance is a part of the zoning ordinance and applies to residential projects of seven or more units." Source: https://www.aducalifornia.org/best-practices/
