Perth & Western Australia
Council Approval
Fast-track your Perth council approval with one team coordinating drawings, consultants, and lodgement. Fewer knock-backs, clearer communication, and a smoother path to site start.
Stress-free council approvals for new homes and renovations
We brief consultants, prepare compliant drawings, and lodge on your behalf—so you spend less time deciphering forms and more time moving your build forward.
Faster approvals
A certified CDC means council has 10 business days to approve, compared to 25+ days for uncertified applications.
Fewer knock-backs
We check zoning, overlays, and compliance before lodgement so your application goes in right the first time.
How We Work
From audit to approval, we keep it moving.
We scope what the council needs and manage every step so you have a single point of contact from first drawing to final approval.
Scope & checklist
We audit zoning, overlays, BAL, and site constraints to confirm the exact paperwork you need.
Documentation
Drafting and consultants run in parallel so drawings, reports, and forms stay aligned.
Certification & submission
We deliver a certified set, lodge with council, and handle RFIs or tweaks without losing time.
Pre-construction handover
You get a clean approval pack and next-step guidance for builders and certifiers.

Council Approval FAQs
Common questions about building permits, CDC certification, and the approval process in Western Australia.
As part of your building permit application, the proposed designs should be certified and comply with the relevant statutory requirements before you apply for a building permit. A registered private building surveyor can assess your plans and specifications of a building.
An uncertified building permit application means that a registered private building surveyor has not assessed the plans and specifications of a proposed building. The drawings and documents submitted with your permit application will require assessment by the City's building surveyors.
Getting a CDC before you apply for your building permit will speed up your permit application time. The Council has 10 business days to approve or refuse a certified building permit application. In comparison, an uncertified CDC can take more than 25 business days, and it is less likely a Private CDC would be refused.
Most building work in Western Australia requires a Building permit. Any work that involves developing new structures, alterations or extensions and changes in ground levels must have a building permit. These include the following: Dwellings and Additions, Commercial and Industrial, Carports and Patios, Sheds and Garages, Front fences, Retaining Walls, Decking, Rainwater Tanks, Swimming Pools and Spas.
