Do relocated buildings have to meet wind load requirements at the new site?
If you move a building in California, the CEBC requires it to meet the applicable California Building Code or California Residential Code wind rules at the new site. Two limited exceptions in **§ 1402.3** allow skipping upgrades only for certain small residences/Group U uses when the new‑site wind is not higher than the old site, or for structural elements whose stress rises by no more than **10%**; otherwise plan to design to the new‑site CBC/CRC wind conditions and expect inspections and any required repairs.
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
Buildings moved to a new location must meet the wind load provisions of the California Building Code (CBC) or the California Residential Code (CRC) that apply at the new site — this is the rule in § 1402.3 of the CEBC. Two limited exceptions are provided in § 1402.3: (1) detached one‑ and two‑family dwellings and Group U occupancies when wind loads at the new location are not higher than at the original site, and (2) structural elements whose stress is not increased by more than 10 percent.
The single most important rule: if the wind demands at the new site are higher than at the original site, the relocated building must meet the CBC/CRC wind provisions at the new site (unless a specific CEBC exception applies).
Requirements in detail
Basic rule
- The CEBC requires relocated buildings to comply with the wind provisions of the applicable code for new construction: CBC for nonresidential and many commercial structures or CRC for residential work where applicable — this compliance is tied to the wind provisions referenced in § 1402.3.
Who must comply
- All relocated or moved buildings, except where specifically excepted by § 1402.3.
- Chapter 14 of the CEBC governs moved/relocated buildings and is the chapter to consult for other relocation requirements (foundations, inspections, etc.).
What “comply with CBC/CRC wind provisions” means
- The CEBC does not restate CBC/CRC wind maps or detailed wind‑load calculations; it requires compliance with those codes’ wind provisions at the new location. You therefore must determine the basic wind speed, exposure, topography, etc., under the CBC/CRC and design accordingly. The CEBC directs users to those codes via § 1402.3.
- If the relocated structure is subject to other Chapter 14 requirements (foundation, connections, inspection), those must also be satisfied in addition to the wind‑load provisions.
CEBC inspections and repair authority
- The code official may require inspection of structural parts of the relocated building and require repairs before final approval (see CEBC’s relocation inspection provisions).
Decision‑relevant dimensions/values (quick reference table)
| Decision item | What to check / value | Applies to | Code Reference |
|---|---|---|---|
| Whether wind provisions apply | If wind loads at new site are higher than at previous site → CBC/CRC wind provisions required | All relocated buildings | § 1402.3 |
| Residential exception | If detached one‑ and two‑family dwellings or Group U and new site wind ≤ old site wind → exception allowed | Detached 1–2 family & Group U | § 1402.3 Exception 1 |
| Structural element tolerance | If stress on a structural element is increased by ≤ 10% → that element may be excepted | Any structure element | § 1402.3 Exception 2 |
| Foundation & connection | Foundation and connections must comply with CBC or CRC as applicable | All relocated buildings | § 1402.2 / 1402.2.1 |
| Inspection requirement | Code official may inspect and require repairs prior to final approval | All relocated buildings | § 1402.7 |
Exceptions & special cases
- Exception 1 (limited building types): Detached one‑ and two‑family dwellings and Group U occupancies are exempt from having to meet higher wind provisions at the new site only when the wind loads at the new location are not higher than those at the previous location. § 1402.3 contains this exception.
- Exception 2 (local increase limited): Structural elements whose stress is not increased by more than 10 percent by the relocation may be excluded from the requirement to upgrade to the new wind provisions. § 1402.3 contains this exception.
- Other Chapter 14 provisions still apply even when a wind exception is used — e.g., foundation requirements (§ 1402.2) and inspection/repair authority (§ 1402.7) remain applicable.
- Appendix C (Guidelines for wind retrofit) contains voluntary prescriptive measures for wind resistance (useful references for mitigation), but Appendix C is not a substitution for meeting CBC/CRC wind provisions when they are required by § 1402.3.
If you need the numerical wind speed or exposure at a location, consult the CBC/CRC wind provisions (CBC §1609 and related sections) — the CEBC points to those codes but does not reproduce their wind maps or tables. The CEBC text requires compliance with those provisions but does not give the wind speeds itself.
Common mistakes
- Assuming every relocation automatically requires no wind upgrades. The CEBC requires CBC/CRC compliance when the new‑site wind demands are higher; only certain small residential and Group U moves may avoid upgrades if wind demands are not higher. Do not skip the wind comparison.
- Forgetting to check both basic wind speed and exposure/topography. The CEBC requires compliance with the applicable CBC/CRC wind provisions — those provisions include multiple parameters (basic wind speed, exposure, importance factor). The CEBC does not remove those requirements.
- Overlooking foundation and connection requirements: even where a wind exception applies, foundation and connection work must meet CBC/CRC as required by § 1402.2 and § 1402.2.1.
- Neglecting the inspection step: the code official can require inspections and repairs before final approval — plan for possible required repairs identified after inspection.
Worked example — concrete scenario
Scenario: A detached single‑family house is moved from Site A to Site B.
- Determine wind demands at Site A and Site B using the CBC/CRC wind provisions (basic wind speed, exposure, etc.). (CEBC requires compliance with CBC/CRC at the new site via § 1402.3; CEBC does not list the wind speeds itself.)
- Suppose Site A basic wind speed = 90 mph (V), Site B basic wind speed = 110 mph (V). Because Site B wind > Site A wind, the CEBC requires the relocated building to comply with CBC/CRC wind provisions at Site B. The residential exception in § 1402.3 applies only when the new location wind is not higher; here it is higher, so no exception applies.
- The practical actions: have a registered design professional evaluate the structure for wind resistance, upgrade roof ties, connections and any lateral wind‑resisting elements as required by the CBC/CRC at the 110 mph design condition, and provide documentation to the authority having jurisdiction. Also ensure foundations and connections comply per § 1402.2.
- If instead Site B had a basic wind speed of 85 mph (less than Site A’s 90 mph), the CEBC’s Exception 1 would allow the detached single‑family dwelling to be exempt from meeting new‑site wind provisions (provided it qualifies as detached 1–2 family / Group U). But inspections and other Chapter 14 requirements still apply.

CHAPTER C2 ROOF DECK FASTENING FOR HIGH-WIND AREAS
SECTION C201—GENERAL
[BS] C201.1 Purpose. This chapter provides prescriptive methods for partial structural retrofit of an existing building to increase its resistance to wind loads. It is intended for voluntary use where the basic wind speed, V, is greater than 130 mph (58 m/s) in accordance with Figure 1609.3(2) of the California Building Code and for reference by mitigation programs. The provisions of this chapter do not necessarily satisfy requirements for new construction. Unless specifically cited, the provisions of this chapter do not necessarily satisfy requirements for structural improvements triggered by addition, alteration, repair, change of occupancy, building relocation or other circumstances.
[BS] C201.2 Eligible conditions. The provisions of this chapter are applicable only to buildings that meet either of the following eligibility requirements:
- Buildings assigned to Risk Category I or II in accordance with Table 1604.5 of the California Building Code .
- Buildings within the scope of the California Residential Code .
SECTION C202—ROOF DECK ATTACHMENT FOR WOOD ROOFS
CEBC § 102.4 High relevance — show source text
Chapter 14 is applicable to any building that is moved or relocated. This chapter is independent of any of the three compliance methods and focuses on the structural loads where the building is being relocated.
Chapter 15 Construction Safeguards.
Chapter 15 establishes specific regulations in order to minimize the risk to the public and adjacent property during construction. Additionally, this chapter addresses fire and life safety and means of egress during the construction process. This includes requirements for a site safety plan. This chapter is also consistent with Chapter 33 of the CBC and Chapter 33 of the California Fire Code (CFC).
Chapter 16 Referenced Standards.
Chapter 16 lists all of the product and installation standards and codes that are referenced throughout Chapters 1 through 15 and includes identification of the promulgators and the section numbers in which the standards and codes are referenced. As stated in Section 102.4, these standards and codes become an enforceable part of the code (to the prescribed extent of the reference) as if printed in the body of the code.
Appendix A Guidelines for the Seismic Retrofit of Existing Buildings.
Appendix A provides guidelines for upgrading the seismic resistance capacity of different types of existing buildings. It is organized into separate chapters which deal with buildings of different types, including unreinforced masonry buildings, reinforced concrete and reinforced masonry wall buildings, and lightframe wood buildings. This appendix includes its own referenced standards.
Appendix B Supplementary Accessibility Requirements for Existing Buildings and Facilities.
Chapters 11A and 11B of the CBC contain provisions that set forth requirements for accessibility to buildings and their associated sites and facilities for people with physical disabilities. Appendix B was added to address accessibility in construction for items that are not typically enforceable through the traditional building code enforcement process.
Appendix C Guidelines for the Wind Retrofit of Existing Buildings.
The purpose of Appendix C is to provide voluntary prescriptive alternatives for addressing the retrofit of buildings in high-wind areas. Currently, there are two chapters which deal with the retrofit of gable ends and the fastening of roof decks, Appendix Chapters C1 and C2, respectively. This appendix includes its own referenced standards.
Appendix D Board of Appeals.
Appendix D contains the provisions for appeal and the establishment of a board of appeals. The provisions include the application for an appeal, the makeup of the board of appeals and the conduct of the appeal process.
Appendix E Temporary Emergency Uses.
Appendix E is intended to provide guidance for designers, engineers, architects and fire and building officials on allowing temporary emergency uses of existing buildings with respect to the minimum code requirements. This appendix is a template or checklist that references the relevant code requirement of concerns.
Resource A Guidelines on Fire Ratings of Archaic Materials and Assemblies.
In the process of repair and alteration of existing buildings, based on the nature and the extent of the work, the CEBC might require certain upgrades in the fire-resistance rating of building elements, at which time it becomes critical for the designers and the code
xiv 2025 CALIFORNIA EXISTING BUILDING CODE
on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.
officials to be able to determine the fire-resistance rating of the existing building elements as part of the overall evaluation for the assessment of the need for improvements. These guidelines are based upon the Guideline on Fire Ratings of Archaic Materials published by the National Institute of Building Sciences (NIBS).

If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, include either of the following:
- Any project for improvement of a building required to correct existing health, sanitary or safety code violations identified by the code official and that is the minimum necessary to ensure safe living conditions.
- Any alteration of a historic structure, provided that the alteration will not preclude the structure’s continued designation as a historic structure.
[BS] SUBSTANTIAL STRUCTURAL ALTERATION. An alteration in which the gravity load-carrying structural elements altered within a 5-year period support more than 30 percent of the total floor and roof area of the building or structure. The areas to be counted toward the 30 percent shall include mezzanines, penthouses, and in-filled courts and shafts tributary to the altered structural elements.
[BS] SUBSTANTIAL STRUCTURAL DAMAGE. A condition where any of the following apply:
- The vertical elements of the lateral force-resisting system have suffered damage such that the lateral load-carrying capacity of any story in any horizontal direction has been reduced by more than 33 percent from its predamage condition.
- The capacity of any vertical component carrying gravity load, or any group of such components, that has a tributary area more than 30 percent of the total area of the structure’s floor(s) and roof(s) has been reduced more than 20 percent from its predamage condition, and the remaining capacity of such affected elements, with respect to all dead and live loads, is less than 75 percent of that required by the California Building Code for new buildings of similar structure, purpose and location.
- The capacity of any structural component carrying snow load, or any group of such components, that supports more than 30 percent of the roof area of similar construction has been reduced more than 20 percent from its predamage condition, and the remaining capacity with respect to dead, live and snow loads is less than 75 percent of that required by the Califor- nia Building Code for new buildings of similar structure, purpose and location.
For purposes of this definition, work done to implement repairs shall not be considered damage that reduces structural capacity.
SUBSTANTIAL STRUCTURAL DAMAGE. [OSHPD 1 & 1R] A condition where any of the following apply: 1. The vertical elements of the lateral force-resisting system have suffered damage such that the lateral load carrying capacity of any story in any horizontal direction has been reduced by more than 10 percent from its predamage condition. 2. The capacity of any vertical component carrying gravity load, or any group of such components, has a tributary area more than 15 percent of the total area of the structure’s floor(s) and roof(s), has been reduced more than 10 percent from its predamage condition, and the remaining capacity of such affected elements, with respect to all dead and live loads, is less than 75 percent of that required by the California Building Code for new buildings of similar structure, purpose and location. 3.

Chapter 10 Change of Occupancy.
The purpose of Chapter 10 is to address existing buildings that are subject to a change of occupancy. This chapter is an assembly of requirements to upgrade safety without having to comply fully as a new building. A change of occupancy classification is considered a change of occupancy, however, it will involve a higher level of regulation since the use of the building has made a more significant change.

Chapter 11 Additions.
Chapter 11 provides the requirements for additions, which are considered new construction. The requirements focus on safely integrating the addition with the existing building. This includes issues such as limiting the overall height and area of the building where the addition is not separated by a fire wall.
Chapter 12 Historic Buildings —Reserved
Chapter 12 is not adopted by the State of California. Historic buildings and structures shall comply with Part 8, Title 24, California Code of Regulations.
Chapter 13 Performance Compliance Methods.
Chapter 13 allows for existing buildings to be evaluated to show that alterations or a change of occupancy, while not meeting new construction requirements, will provide a level of safety to demonstrate compliance. Provisions are based on a numerical scoring system involving 21 safety parameters where, when evaluated, such buildings must meet a minimum overall safety score.
Chapter 13 is not adopted by the State of California but may be available for adoption by local ordinance, see Section 1.1.11. See Section 104.11 for consideration of alternative means of compliance.
Chapter 14 Relocated or Moved Buildings.
Chapter 14 is applicable to any building that is moved or relocated. This chapter is independent of any of the three compliance methods and focuses on the structural loads where the building is being relocated.
Chapter 15 Construction Safeguards.
Chapter 15 establishes specific regulations in order to minimize the risk to the public and adjacent property during construction. Additionally, this chapter addresses fire and life safety and means of egress during the construction process. This includes requirements for a site safety plan. This chapter is also consistent with Chapter 33 of the CBC and Chapter 33 of the California Fire Code (CFC).
Chapter 16 Referenced Standards.
Chapter 16 lists all of the product and installation standards and codes that are referenced throughout Chapters 1 through 15 and includes identification of the promulgators and the section numbers in which the standards and codes are referenced. As stated in Section 102.4, these standards and codes become an enforceable part of the code (to the prescribed extent of the reference) as if printed in the body of the code.
Appendix A Guidelines for the Seismic Retrofit of Existing Buildings.
Appendix A provides guidelines for upgrading the seismic resistance capacity of different types of existing buildings. It is organized into separate chapters which deal with buildings of different types, including unreinforced masonry buildings, reinforced concrete and reinforced masonry wall buildings, and lightframe wood buildings. This appendix includes its own referenced standards.
Appendix B Supplementary Accessibility Requirements for Existing Buildings and Facilities.
Chapters 11A and 11B of the CBC contain provisions that set forth requirements for accessibility to buildings and their associated sites and facilities for people with physical disabilities. Appendix B was added to address accessibility in construction for items that are not typically enforceable through the traditional building code enforcement process.
Appendix C Guidelines for the Wind Retrofit of Existing Buildings.

The CEBC requirements for construction safeguards are directly correlated to the requirements of the CBC. The following table shows chapters of the CBC that are correlated with the CEBC:
CEBC/CBC CORRELATED TOPICS Col2 Col3 CEBC CHAPTER/SECTION CBC CHAPTER/SECTION SUBJECT Chapter 15 Chapter 33 Construction safeguards Chapter 1 Scope and Administration.
Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. The provisions of Chapter 1 establish the authority and duties of the code official appointed by the authority having jurisdiction and also establish the rights and privileges of the design professional, contractor and property owner.
Chapter 2 Definitions.
Chapter 2 is the repository of the definitions of terms used in the body of the code. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined.

Chapter 3 Provisions for All Compliance Methods.
Chapter 3 guides the use of the three compliance methods of the CEBC and provides requirements that apply globally. The globally applicable requirement include general requirements related to buildings materials and other applicable codes, storm shelters, structural loads, in-situ load tests, accessibility, smoke alarms, carbon monoxide detection and exterior wall coverings.
Chapter 3A Provisions for All Compliance Methods.
Chapter 3A controls the compliance options for alteration, repair, addition, evaluation and change of occupancy of existing structures regulated by the Department of Health Care Access and Information/Office of Statewide Hospital Planning and Development, which include hospitals and correctional treatment centers (applications listed in Sections 1.10.1 (OSHPD 1).
Chapter 4 Repairs.
Chapter 4, a chapter independent of the three compliance methods, governs the repair of existing buildings. The provisions define conditions under which repairs may be made using materials and methods like those of the original construction or the extent to which repairs must comply with requirements for new buildings.
Chapter 4A Repairs.
Chapter 4A governs the repair of existing buildings regulated by the Department of Health Care Access and Information/Office of State- wide Hospital Planning and Development, which include hospitals and correctional treatment centers (applications listed in Sections 1.10.1 (OSHPD 1).
CEBC § 319.10.2 Medium relevance — show source text
319.10.2 Preconstruction meeting. A preconstruction meeting is mandatory for all projects which require structural observation. The meeting shall include, but is not limited to, the registered design professional, structural observer, general constructor, affected subcontractors, the project inspector and a representative of the enforcement agency (designated alternates may attend if approved by the structural observer). The structural observer shall schedule and coordinate this meeting. The purpose of the meeting is to identify and clarify all essential structural components and connections that affect the lateral and vertical load systems and to review scheduling of the required observations for the project’s structural system retrofit.
319.11 Temporary actions. When compatible with the building use, and the time phasing for both use and the retrofit program, temporary shoring or other structural support is permitted to be considered. Temporary bracing, shoring and prevention of falling hazards are permitted to be used to qualify for Item 1 in Section 319.12 that allows inadequate capability in some existing components, as long as the required performance levels given in Section 317 can be provided by the permanent structure. The consideration for such temporary actions shall be noted in the design documents.
319.12 Voluntary modifications to the lateral-force resisting system. Where modifications of existing structural components and additions of new structural components are initiated for the purpose of improving the lateral-force resisting strength or stiffness of an existing structure and they are not required by other sections of this code, then they are permitted to be designed to meet an approved seismic performance criteria provided that an engineering analysis is submitted that follows: 1. The capacity of existing structural components required to resist forces is not reduced, unless it can be demonstrated that reduced capacity meets the requirements of Section 319.8. 2. The lateral loading to or strength requirement of existing structural components is not increased beyond their capacity. 3. New structural components are detailed and connected to the existing structural components as required by the California Building Code. 4. New or relocated nonstructural components are detailed and connected to existing or new structural components as required by the California Building Code. 5. A dangerous condition is not created.
Use of ASCE 41 Tier 1 and Tier 2 deficiency only retrofit procedures are pre-approved for use where Section 317.3 does not require an
assessment.
319.12.1 State-owned buildings. [BSC] Voluntary modifications to lateral force-resisting systems conducted in accordance with Appendix A of this code and the referenced standards of the California Building Code shall be permitted.
319.12.1.1 Design documents. [BSC] When Section 319.12 is the basis for structural modifications, the approved design documents must clearly state the scope of the seismic modifications and the accepted criteria for the design. The approved design documents must clearly have the phrase “The seismic requirements of the California Existing Building Code have not been checked to determine if these structural modifications meet the full seismic evaluation and strengthening requirements of Sections 317-322: the modifications proposed are to a different seismic performance standard than would be required in Section 319 if they were not voluntary as allowed in Section 319.12.”

Frequently asked questions
How do I determine whether wind loads at the new site are “higher” than at the old site?
Compare the design wind demands derived from the CBC/CRC for both sites (basic wind speed, exposure, importance factor, topography). The CEBC requires that you use the CBC/CRC provisions for that comparison; the CEBC (§ 1402.3) does not itself list wind speeds.
If only a few roof connections need strengthening, can I use the 10% structural‑stress exception?
The CEBC allows an exception where a structural element’s stress is not increased by more than 10 percent. Apply that criterion to the affected elements and document the analysis; otherwise the CBC/CRC wind provisions apply. § 1402.3 is the controlling text.
Does Appendix C (wind retrofit guidelines) replace the CBC/CRC requirements after relocation?
No. Appendix C provides voluntary prescriptive retrofit guidance for wind resistance; it does not substitute for satisfying CBC/CRC wind provisions when § 1402.3 requires compliance at the new site.
Who inspects the building after relocation?
The code official for the authority having jurisdiction can inspect or require approved professionals to inspect the relocated building and may require repairs before final approval (see § 1402.7).
Where do I find the CBC/CRC wind provisions referenced by § 1402.3?
The CEBC directs you to the California Building Code or California Residential Code wind provisions; consult those codes (for example, CBC wind provisions begin in Chapter 16/section references such as § 1609) for the numerical wind speeds and detailed rules. The CEBC does not reproduce those tables.
