minimum noise insulation performance standards for new residential dwelling units
and additions of habitable rooms to existing residential dwelling units to protect
public health, safety, and welfare from the effects of excessive noise, including
ORDINANCE NO. 1641
PAGE 9 of 123
without limitation, indoor quality of life, speech interference, and sleep disruption.
1206.6.03 Applicability. This section applies to all newly constructed residences
and habitable room additions to existing residence
1206.6.04 Definitions. For purposes of this section, the following words must have
the following meaning:
"Community Noise Equivalent Level (CNEL)" means the noise measure defined in
21 Code of California Regulations § 5001(d), and any successor regulation or
amendment.
"Habitable Room" means a room that is a space in a structure for living, sleeping,
eating, or cooking. Bathrooms, toilet compartments, closets, halls, storage or utility
space, garages, and similar areas are not considered habitable space.
"LAX" means Los Angeles International Airport. "Noise Impact Boundary for LAX"
means the area around LAX as defined in 21 California code of regulations
§ 5001(1), and any successor regulation or amendment. The city's building safety
department must at all times maintain a current map of the noise impact boundary.
The latest published map by LAWA located at the Building Safety Counter shall be
used as the basis for determination. "Residence" means any occupancy group R
building as used in El Segundo title 13 of the El Segundo municipal code.
1206.6.05: Standards.
Any new residence or addition of one or more habitable rooms to an existing
residence that is within the noise impact boundary for LAX must be designed to
ensure that internal noise levels due to LAX do not exceed 45 dB CNEL. This
standard may be satisfied in two ways: (1) by performing the acoustical analysis
described in section 1206.6.06, below, or (2) by employing the prescribed
construction methods described in section 1206.6.07, below.
1206.6.06: Acoustical Analysis.
A building permit application for a new residence or addition of one or more
habitable rooms to an existing residence must comply with the minimum noise
insulation performance standards established in this section if it includes an
acoustical analysis demonstrating that the proposed design will ensure that
internal noise levels due to LAX aircraft noise will not exceed 45 dB CNEL. The
acoustical analysis shall be proven to meet the standard by providing post-
construction/pre-occupancy acoustic measurement to verify compliance with the
45 dB CNEL standard. The Building Official has the discretion to implement
policies that meet the intent of this code section.
ORDINANCE NO. 1641
PAGE 10 of 123
A. The acoustical analysis must be prepared by a person experienced in
the field of acoustical engineering. The analysis must consider and include:
the topographical relationship between LAX aircraft noise sources and the
dwelling site, the characteristics of those noise sources, predicted noise
spectra and levels at the exterior of the dwelling site, the basis for this
prediction (measured or obtained from published data), the noise insulation
measures to be employed, and the effectiveness of the proposed noise
insulation measures.
B. If the interior allowable noise levels are to be met by requiring that
windows be unopenable or closed, the design for the structure must also
specify a ventilation or air-conditioning system to provide a habitable interior
environment, having at least 2 air exchanges per hour for the affected
rooms. The ventilation system must not compromise the interior room noise
reduction.

plans and specifications for checking by the city. The plan check fee shall
be based on the total volume of the excavation and fill, on the site. The
grading plan check fee shall be recalculated each time the grading plan
volume of excavation and fill exceeds the volume used to determine the
original plan check fee, and the applicant shall pay the difference between
the revised and original fee before the revised grading plans are accepted
for review by the city. The original grading plan check fee includes the cost
to the applicant for the original submittal plus two additional submittals of
corrected grading plans and specifications. When required by the building
official, the applicant shall pay a supplemental grading plan check fee in
accordance with the fee resolution established by the city council.
3. Whenever the applicant submits a grading plan for plan check that is
substantially different in design of the earthwork as compared to previously
submitted grading plans, the submittal shall be considered an original and
a new grading plan check fee shall be determined and paid to the city as
provided in this section.
4. The applicant shall pay a grading permit fee prior to the issuance of a
grading permit by the city. The fee shall be based on the total volume of
excavation and fill, on the site. If, during grading operations, the plans and
specifications for the grading project are revised increasing the volume of
excavation, fill, or a combination thereof above the volume that was used to
determine the grading permit fee, the applicant shall pay to the city the
difference between the original grading permit fee and the recalculated fee
before work may resume under the grading permit.

the effects of excessive noise, including without limitation, indoor quality of life,
speech interference, and sleep disruption.
R341.3 Applicability.
This section applies to all newly constructed residences and habitable room
additions to existing residences.
R341.4 Definitions.
For purposes of this section, the following words must have the following meaning:
"Community Noise Equivalent Level (CNEL)" means the noise measure defined in
21 Code of California Regulations § 5001(d), and any successor regulation or
amendment.
"Habitable Room" means a room that is a space in a structure for living, sleeping,
eating, or cooking. Bathrooms, toilet compartments, closets, halls, storage or utility
space, garages, and similar areas are not considered habitable space.
"LAX" means Los Angeles International Airport."Noise Impact Boundary for LAX"
means the area around LAX as defined in 21 California code of regulations
§ 5001(1), and any successor regulation or amendment. The city's building safety
department must at all times maintain a current map of the noise impact boundary.
The latest published map by LAWA located at the Building Safety Counter shall be
used as the basis for determination.
"Residence" means any occupancy group R building as used in El Segundo Title
13 of the El Segundo municipal code.
R341.5 Standards.
Any new residence or addition of one or more habitable rooms to an existing
residence that is within the noise impact boundary for LAX must be designed to
ensure that internal noise levels due to LAX do not exceed 45 dB CNEL. This
standard may be satisfied in two ways: (1) by performing the acoustical analysis
described in section R341.1207.6.06, below, or (2) by employing the prescribed
construction methods described in section R341.1207.6.07, below
R341.6 Acoustical Analysis.
A building permit application for a new residence or addition of one or more
habitable rooms to an existing residence must comply with the minimum noise
insulation performance standards established in this section if it includes an
acoustical analysis demonstrating that the proposed design will ensure that
internal noise levels due to LAX aircraft noise will not exceed 45 dB CNEL. The
ORDINANCE NO. 1641
PAGE 72 of 123
acoustical analysis shall be proven to meet the standard by providing post-
construction/pre-occupancy acoustic measurement to verify compliance with the
45 dB CNEL standard. The Building Official has the discretion to implement
policies that meet the intent of this code section.
A. The acoustical analysis must be prepared by a person experienced in
the field of acoustical engineering. The analysis must consider and include:
the topographical relationship between LAX aircraft noise sources and the
dwelling site, the characteristics of those noise sources, predicted noise
spectra and levels at the exterior of the dwelling site, the basis for this
prediction (measured or obtained from published data), the noise insulation
measures to be employed, and the effectiveness of the proposed noise
insulation measures.
B. If the interior allowable noise levels are to be met by requiring that
windows be unopenable or closed, the design for the structure must also
specify a ventilation or air-conditioning system to provide a habitable interior
environment, having at least 2 air exchanges per hour for the affected
rooms. The ventilation system must not compromise the interior room noise
reduction.
R341.7 Prescribed Construction Methods.
A building permit application for a new residence or addition of one or more
habitable rooms to an existing residence must comply with the minimum noise
insulation performance standards established in this section if the design
incorporates the following construction methods.
