The construction, addition, or alteration of buildings is governed by the California Contractors License Law
(commencing with Business Professions Code section 7000). The law has an exemption that allows a person
who is not a California Licensed Contractor to construct a single-family residential structure and engage in
home improvements and repairs, provided they meet certain requirements. (Form B-61 provides information
about the requirements that apply to Owner-Builders makes you aware of your responsibilities and possible
risk you may incur by having a permit issued to an Owner-Builder.) Permits for multi-family projects are only
to be issued to California Licensed Contractors. Refer to Form B-16 for other frequently asked questions.

I/We certify that I/we a legal right, interest, or entitlement to the use of the property that is the
subject of this application.
I/We understand that State law mandates the Applicant to provide an estimated value of all work
proposed (B-29 form). I/We hereby certify the construction valuation provided is accurate and
includes all proposed work such as all structural work, finish work, painting, roofing, electrical,
plumbing, heating, air conditioning, elevator, labor costs, and all permanent equipment and systems.
If the valuation is underestimated, the permit may be denied, unless the Applicant can show detailed
estimates to meet the approval of the Building Official.
If the Applicant is not the Property Owner, both the Property Owner and Applicant (authorized
Contractor or authorized Agent of the Property Owner/Contractor) must sign below. By signing this
declaration, the Property Owner authorizes the Applicant listed in this application to act as the
Property Owner's Agent on all matters before the city pertaining to development on this property.
I/We understand that State law requires construction to be done by a Licensed Contractor and the
Property Owner may apply for an Owner-Builder permit under an exemption from the law.
□ A. If the Contractor is the Applicant, the License Contractor Declaration on page 4
must be completed.
□ B. If the Applicant is an Owner-Builder, an Owner-Builder affidavit is required and
must be submitted (Form B-61). The city will not issue a building permit until this form
has been submitted. The License Contractor Declaration on page 4 does not need to
be submitted.
I/We have read this application form in its entirety and reviewed the building permit application and
the information I/we have provided is true and correct to the best of our knowledge. Grade lines as
shown on drawings accompanying this application are assumed to be correct. This certifies that the
description of the project and all the plans and supporting documentation; including the location and
labeling of all existing and proposed buildings, structures, access roads, and utilities and easements;
are accurate in all material respects as of the date when made. I/We understand that it is my
responsibility to ensure that statements and representations are not misleading. I/We agree to
promptly remove, correct, or add information as needed to correct any misleading or materially
inaccurate information. I/We understand that any misstatement or omission of the requested

subsequent representations, or for the seeking of such other and further relief as deemed appropriate
by the City of Carlsbad.

I/We certify that I am (we are) aware of all permit requirements and will not willfully deviate from the
approved plan. I/We agree to comply with all applicable city and county ordinances and state laws
relating to building construction. I/We assume full responsibility for the satisfactory completion of all
work authorized under the permit(s), including work performed prior to assuming control.
After construction begins, I/we understand that a height certification, pad certification, or boundary
certification may need to be submitted to the Building Inspector, when required.
I understand that a building permit application will expire If a permit has not been issued/obtained
within one year from the application date (original filing date), unless an extension of time has been
granted (Form B-25). With some limited exceptions, if a building permit application expires and there
is interest in proceeding with the same project, a new application will be required and the project will
be subject to new fees and regulations that are in effect at the time the new application is submitted.
After submitting the application, the Billing Party designated as part of the application will be sent
future city invoices for above referenced building permit(s). I understand that if a permit fee or
development impact fee refund is issued, the check will be mailed to the financial responsible party
(the actual person or company that paid the invoice). If the information on file for the financially
responsible party is outdated or inaccurate, it must be corrected before the refund can be sent. Form
B-49B may be completed to update the financially responsible party's contact information.
I/We agree to waive, release, and discharge the City of Carlsbad ("City") and its officers, elected or
appointed officials, employees, volunteers and agents (the "Indemnified Parties") from all claims and
demands, rights and causes of action of any kind with respect to the building permit application, the
purpose of which is to challenge, attack set aside, void, modify, or annul the approval or denial of the
application, or the processing thereof, except liability caused by the Indemnified Parties' sole
negligence or willful misconduct, in which case the indemnity received by the city shall be reduced by
the amount: (a) that the city's active negligence contributed to the liability on a comparative basis; or
(b) such other amount as may be required by law. This obligation is effective without reference to the
existence or applicability of any insurance coverages which may have been required by city or any
additional insured endorsements which may extend to Indemnified Parties. Property Owner(s) and
Applicant, on behalf of themselves and all parties claiming under or through them, waive all rights of
subrogation and contribution against the Indemnified Parties while acting within the scope of their
duties, from all claims, losses and liabilities arising out of or incident to activities or operations
performed, regardless of any prior, concurrent or subsequent passive negligence by the Indemnified
Parties.

11.2 Withdrawal Design Values
11.2.1 Lag Screws
11.2.1.1 The withdrawal design values, in lbs.fin. of
penetration, for a single lag screw inserted in side grain,
with the lag screw axis perpendicular to the wood fibers,
shall be determined from Table 11.2A or Equation 11.2-1,
within the range of specific gravities and screw diameters
given in Table 11.2A. Tabulated nominal design values, W,
shall be multiplied by all applicable adjustment factors (see
Table 10.3.1) to obtain allowable design values, W'.
W=180QG312O314 (11.2-1)
11.2.1.2 When lag screws are loaded in withdrawal
from end grain, nominal withdrawal design values, W,
shall be multiplied by the end grain factor, Ceg = 0.75.
11 .2.1.3 When lag screws are loaded in withdrawal,
the allowable tensile strength of the lag screw at the net
(root) section shall not be exceeded (see 10.2.3).
Table 11.2A Lag Screw Withdrawal Design Values (W)1
Tabulated withdrawal design values (W) are in pounds per inch of thread penetration into side grain ofinain member.
Length of thread penetration in main member shall not include the length of the tapered tip (see Appendix L).
