Building consent is the backbone of safe, resilient, and sustainable development in Christchurch. As the city continues to grow and evolve—especially in the wake of the 2011 earthquake and amid ongoing housing pressures—building consent processes have become both more critical and more complex. Christchurch City Council, as the Building Consent Authority (BCA), is responsible for ensuring that all building work complies with the Building Code and relevant planning rules. In recent years, the consent process has faced scrutiny for delays, regulatory changes, and the impact of new national and local policies.

This article provides a comprehensive overview of the Christchurch building consent process in 2025, recent regulatory changes, performance assessments, the impact on developers and homeowners, and the broader context of planning and housing policy in the city.

What Is a Building Consent?

A building consent is formal approval from the local council to undertake building work in accordance with approved plans and specifications. All work must comply with the Building Code, and most projects—whether new homes, renovations, or commercial developments—require consent before work can begin.

Some minor work is exempt, but for most projects, the process is mandatory. Even small standalone dwellings (such as granny flats) still require building consent, though national reforms may soon change this for some types of work.

Key Steps in the Consent Process

Pre-Application Preparation
- Gather site-specific information and understand the requirements that may inform design decisions.
- Prepare detailed plans, specifications, and supporting documents (including certificates from licensed building practitioners, CodeMark certificates, and development contribution notices).
Application Submission
- Applications must be made to the Christchurch City Council BCA, using the prescribed forms and including all required documentation.
- Electronic submission through the council’s Connect system is standard practice.
Vetting
- Vetting officers review the application for completeness. If information is missing, a Request for Information (RFI) is sent to the applicant, pausing the statutory clock until a response is received.
Assessment
- Technical officers assess the application for compliance with the Building Code and relevant planning rules.
- Applications are processed using checklists and documented procedures to ensure consistency.
Decision and Issue
- If compliant, the council grants and issues the building consent, including a Form 5 certificate.
- If not, the application may be declined or further information requested.
Inspections
- Building work is inspected at key stages to ensure it matches the consented plans.
- Any unconsented work or deviations must be addressed before a Code Compliance Certificate (CCC) can be issued.
Code Compliance Certificate (CCC)
- Once work is complete, the owner applies for a CCC. The council inspects the finished work and, if compliant, issues the certificate.

Performance and Compliance: How Is Christchurch Doing?

Accreditation and Assessment

Christchurch City Council’s BCA is regularly assessed for compliance with the Building (Accreditation of Building Consent Authorities) Regulations 2006. The most recent accreditation assessment, conducted in March 2025, reviewed procedures, documentation, and on-site activities.

Application Recording: The council’s Connect system is used to log and track all applications, with records found to be appropriate and accessible.
Assessment Procedures: Applications are reviewed using standardised checklists. Incomplete applications trigger an RFI, ensuring that only complete and compliant applications proceed.
Granting and Issuing Consents: Procedures are well documented, but some minor issues were noted in the legal descriptions on Form 5s and recording of building names or unit numbers. These were addressed during the assessment.

Statutory Timeframes

By law, councils must process building consents within 20 working days. Christchurch’s performance has improved significantly in recent years:

2023–2024: The average compliance rate was about 80.8%, below the national standard.
2024–2025: Compliance improved to 91.7% over the last 12 months, and 95.5% in the last six months.

Despite this progress, delays still occur, often due to RFIs that pause the statutory clock. The council continues to work on streamlining processes and reducing bottlenecks.

Inspection and Compliance Issues

While the council’s inspection procedures are generally robust, some issues were identified:

Inspections were occasionally carried out on building work that differed from the consented documents, and these changes were not always identified or addressed in inspection reports.
Some Code Compliance Certificate decisions were overdue, and the process for owners to request extensions was not clearly documented.

The council has accepted recommendations to improve these areas and is implementing changes to ensure better tracking and documentation.

The RFI Bottleneck

One of the most significant sources of delay is the Request for Information (RFI) process. When applications are incomplete or unclear, the council issues an RFI, stopping the 20-day statutory clock until the applicant responds. Industry feedback suggests that:

RFIs are often issued late in the process, sometimes on the 19th day.
Many RFIs request information already provided or focus on minor details.
The average time to respond to an RFI is around 19 days, extending the total consent process to 34 days or more.

Builders and developers argue that the process has become overly complex, with applications running to thousands of pages compared to just a few dozen 15 years ago. The legacy of the leaky homes crisis and the Christchurch earthquake has made councils more cautious, but the result is a slower, more onerous process.

Volume and Complexity

Christchurch’s post-earthquake rebuild, population growth, and new housing policies have driven up the volume and complexity of consent applications. Multi-unit developments, intensification, and mixed-use projects are now common, requiring more detailed assessment and coordination.

National and Local Policy Changes

Recent changes to planning rules—especially those relating to housing density and the national Medium-Density Residential Standards (MDRS)—have added further layers of complexity. The council must balance national directives with local needs, heritage protection, and infrastructure constraints.

New Planning Rules and Their Impact

Housing and Business Choice Plan Change (Plan Change 14)

In 2025, Christchurch City Council has been at the centre of a major planning overhaul. The Housing and Business Choice Plan Change (Plan Change 14) aims to allow greater housing density and business development across the city, in line with national policy directives.

Government Oversight: The Minister for RMA Reform, Chris Bishop, has the final say on many aspects of the plan. Of 20 alternative recommendations put forward by the council, only three were accepted, with most of the Independent Hearings Panel’s recommendations taking effect immediately.
Key Outcomes: High-density zoning has been expanded in areas like Hornby, Riccarton, and Linwood. The council’s proposal for stricter sunlight access rules was rejected, raising concerns about shading and amenity impacts for neighbours.
Council Response: Mayor Phil Mauger described the outcome as “a kick in the guts,” reflecting frustration at the limited influence local government has had over the final rules.

Development Contributions Policy 2025

Alongside planning changes, the council is updating its Development Contributions Policy, which determines the fees developers pay to fund infrastructure.

Higher Charges: The per-household unit equivalent (HUE) charge in Christchurch Central is set to rise from $8,126.76 (2021) to $29,562.70 (2025), reflecting higher infrastructure costs.
Eligibility Changes: Demand credits for undeveloped land will expire after 10 years, and discounts for small units have been removed. Multi-unit developments will pay higher contributions, and stormwater discounts are now harder to obtain.
No More Remissions: Developers can no longer apply for reductions in “unique and compelling” circumstances.

These changes are designed to ensure growth is funded fairly and infrastructure keeps pace with development, but they also increase costs for developers and, potentially, for homebuyers.

The Homeowner and Developer Experience

For Homeowners

Navigating the Process: The building consent process can be daunting, especially for first-time builders or renovators. Council guidance and support are available, but applicants must prepare detailed documentation and respond promptly to any RFIs.
Costs and Timeframes: Higher development contributions and potential delays can add to the cost and complexity of building or renovating a home.
Future Changes: Planned reforms may exempt some small standalone dwellings from the consent process by 2026, but for now, most projects still require full consent.

For Developers

Increased Costs: Higher development contributions and stricter assessment criteria mean higher upfront costs and more financial risk.
Complexity: Multi-unit and mixed-use developments face more rigorous scrutiny, especially in high-density zones.
Uncertainty: Ongoing changes to planning rules and national standards create uncertainty, making it harder to plan and budget for projects.

Looking Ahead: Reform and Improvement

Streamlining and Digital Transformation

The council is investing in digital tools and process improvements to make the consent process more efficient and transparent. The Connect system allows for online submission, tracking, and communication, reducing paperwork and improving record-keeping.

National Reforms

Work is underway at the national level to simplify the building consent process, particularly for small dwellings and low-risk work. These changes aim to reduce red tape, speed up approvals, and lower costs, while maintaining high standards of safety and quality.

Ongoing Challenges

Despite improvements, challenges remain:

Balancing Speed and Safety: Ensuring that consents are processed quickly without compromising on quality or compliance.
Managing Growth: Providing the infrastructure needed to support a growing and densifying city.
Responding to Change: Adapting to new policies, technologies, and community expectations.

Summary

Building consent in Christchurch is a complex, evolving process shaped by regulatory requirements, local and national policies, and the city’s unique history and growth trajectory. While the council has made progress in improving consent timeframes and digital systems, challenges remain—especially around RFIs, higher development contributions, and the impact of new planning rules. For homeowners and developers, understanding the process and preparing thorough applications is key to avoiding delays and extra costs. As Christchurch continues to grow and change, ongoing reform and investment in consent processes will be essential to building a safe, sustainable, and vibrant city.
