2021 California Code|Civil Code - CIV|DIVISION 4 - GENERAL PROVISIONS|PART 3 - NUISANCE|TITLE 1 - GENERAL PRINCIPLES|Section 3482.1.

3482.1.  (a) As used in this section:(1) “Person” means an individual, proprietorship, partnership, corporation, club, or other legal entity.(2) “Sport shooting range” or “range” means an area designed and operated for the use of rifles, shotguns, pistols, silhouettes, skeet, trap, black powder, or any other similar sport or law enforcement training purpose.(3) “Indoor shooting range” means a totally enclosed facility designed to offer a totally controlled shooting environment that includes impenetrable walls, floor and ceiling, adequate ventilation and lighting systems, and acoustical treatment for sound attenuation suitable for the range’s approved use.(4) “Nighttime” means between the hours of 10 p.m. and 7 a.m.(b) (1) Except as provided in subdivision (f), a person who operates or uses a sport shooting range in this state shall not be subject to civil liability or criminal prosecution in any matter relating to noise or noise pollution resulting from the operation or use of the range if the range is in compliance with any noise control laws or ordinances that applied to the range and its operation at the time construction or operation of the range was approved by a local public entity having jurisdiction in the matter, or if there were no such laws or ordinances that applied to the range and its operation at that time.(2) Except as provided in subdivision (f), a person who operates or uses a sport shooting range or law enforcement training range is not subject to an action for nuisance, and a court shall not enjoin the use or operation of a range, on the basis of noise or noise pollution if the range is in compliance with any noise control laws or ordinances that applied to the range and its operation at the time construction or operation of the range was approved by a local public entity having jurisdiction in the matter, or if there were no such laws or ordinances that applied to the range and its operation at that time.(3) Rules or regulations adopted by any state department or agency for limiting levels of noise in terms of decibel level which may occur in the outdoor atmosphere shall not apply to a sport shooting range exempted from liability under this section.(c) A person who acquires title to or who owns real property adversely affected by the use of property with a permanently located and improved sport shooting range may not maintain a nuisance action with respect to noise or noise pollution against the person who owns the range to restrain, enjoin, or impede the use of the range where there has been no substantial change in the nature or use of the range. This section does not prohibit actions for negligence or recklessness in the operation of the range or by a person using the range.(d) A sport shooting range that is in operation and not in violation of existing law at the time of the enactment of an ordinance described in subdivision (b) shall be permitted to continue in operation even if the operation of the sport shooting range at a later date does not conform to a new ordinance or an amendment to an existing ordinance if there has been no substantial change in the nature or use of the range. Nothing in this section shall be construed to limit the authority of a local agency to enforce any term of a conditional use permit.(e) Except as otherwise provided in this section, this section does not prohibit a local public entity having jurisdiction in the matter from regulating the location and construction of a sport shooting range after the effective date of this section.(f) This section does not prohibit a local public entity having jurisdiction in the matter from requiring that noise levels at the nearest residential property line to a range not exceed the level of normal city street noise which shall not be more than 60 decibels for nighttime shooting. The subdivision does not abrogate any existing local standards for nighttime shooting. The operator of a sport shooting range shall not unreasonably refuse to use trees, shrubs, or barriers, when appropriate, to mitigate the noise generated by nighttime shooting. For the purpose of this section, a reasonable effort to mitigate is an action that can be accomplished in a manner and at a cost that does not impose an unreasonable financial burden upon the operator of the range.(g) This section does not apply to indoor shooting ranges.(h) This section does not apply to a range in existence prior to January 1, 1998, that is operated for law enforcement training purposes by a county of the sixth class if the range is located without the boundaries of that county and within the boundaries of another county. This subdivision shall become operative on July 1, 1999.(Amended by Stats. 1998, Ch. 141, Sec. 1. Effective July 13, 1998.)
