Residential HVAC condenser units in Carmichael must comply with Sacramento County Code §6.68.070 - 55 dBA day / 50 dBA night at the receiving residential property line. Title 24 also caps new equipment sound power.
Air conditioner condenser noise is enforced as 'continuous source noise' under SCC §6.68.070. For a single-family receiver, the unit must not push sound above 55 dBA at the property line during 7 a.m.-10 p.m. or 50 dBA at night. Common Carmichael complaints involve older single-stage condensers placed too close to a neighbor's bedroom wall. California Title 24 §150.0(h) requires new installation HVAC equipment to meet specific sound-power ratings, and ENERGY STAR-certified condensers typically run 65-72 dBA at the unit (meeting property-line limits if set back appropriately). Pool pumps and heat pump pool heaters are similarly regulated.
Violations of §6.68.070 are misdemeanors under §6.68.140 with administrative citation options $100/$200/$500. Common remedy: install a sound blanket, build a sound fence, or relocate the condenser.
