5 Crucial Site Preparation Steps for Inner West Sydney Renovations

The five crucial site preparation steps for an Inner West Sydney renovation are asbestos testing and removal, access assessment, underground service checks, excavation and shoring compliance, and waste segregation. Completing these steps before work begins helps identify site risks early and keeps the renovation safer and better organised.

Key takeaways

• Test for asbestos first: Older Inner West homes should be assessed for asbestos before demolition or trade work begins
• Assess site access early: Measure ground and overhead clearance before choosing excavation equipment
• Check services before digging: Confirm underground utilities before excavation to reduce the risk of damaging hidden services
• Plan excavation and waste: Address shoring requirements and separate waste streams before site work gets underway

It is not going to be the same playbook for renovating a home in the Inner West and one in a newer suburb. Federation cottages, Victorian terraces, and post-war bungalows dominate the streetscape, most sitting on narrow blocks with laneway or side-street access only.

That combination – older construction materials and constrained physical access – means site preparation carries more weight here than it does elsewhere. Skipping or rushing it is where most costly mid-project surprises come from.

The blog discusses five preparation steps worth getting right before any work starts.

Why Inner West Sites Need Extra Preparation

The housing stock is the main factor. Terrace homes and cottages built through the early-to-mid 20th century line most Inner West streets, and a large share of them fall within heritage conservation areas, which adds another layer of process on top of the physical site constraints. Blocks are typically long and narrow, streets are tight, and rear laneway access is common rather than the exception.

These conditions can make tight access excavation a key consideration before equipment and excavation work are scheduled.

What Site Preparation Steps to Undertake

Each of the steps mentioned below addresses a specific risk that shows up more often on Inner West sites than on a standard suburban block.

1. Asbestos Testing and Licensed Removal

This is the step with the most legal weight, and it’s non-negotiable for homes of this age.

According to the NSW EPA, 1 in 3 Australian homes contain asbestos, and any home built before 1990 should be assumed to carry some risk until tested.

SafeWork NSW requires different licences depending on what’s found. A Class B licence covers non-friable asbestos removal up to 10m² within a seven-day period, while a Class A licence is required for friable asbestos or any quantity above that threshold. Licensed asbestos removal contractors in Sydney must also notify SafeWork NSW at least five full days before work begins.

Important Note: Asbestos testing should happen before any other trades or preparation work starts on site. Disturbing suspected materials before testing is one of the most common and preventable compliance breaches on older renovation projects.

2. Access Assessment for Tight Sites

Standard excavators simply are not going to fit down many Inner West laneways or side passages. Assessing access before equipment is booked avoids the far more expensive problem of discovering on-site that machinery cannot reach the work area.

• Measure laneway and side-access widths before finalising an excavation plan
• Compact or mini excavators are often the only viable option on terrace blocks
• Check overhead clearance too; low power lines and overhanging trees affect what can pass through, not just ground-level width

Pro Tip: Where tight access excavation is unavoidable, confirm with the contractor whether material needs to be removed by hand in sections before machinery can even begin, since this changes both the timeline and the sequencing of the whole site prep phase.

3. Locating Underground Services Before Digging

Older Inner West properties often have services that do not match what’s shown on current utility maps – ageing terracotta stormwater lines, shared sewer connections between adjoining terraces, and gas or electrical runs that have been altered over decades of past renovations.

A Before You Dig Australia (BYDA) request should be lodged well ahead of any excavation. On older, high-density blocks, it’s worth treating the returned information as a starting point rather than a guarantee, given how often unrecorded alterations exist on these properties.

4. Excavation Safety and Shoring Compliance

Excavation work is classified as high-risk construction work under SafeWork NSW’s Excavation Work Code of Practice, which means a Safe Work Method Statement is required before work begins.

On narrow Inner West blocks, this also usually means proper shoring or benching to prevent ground collapse, since there’s often little to no room for a wide, gradually sloped excavation edge.

5. Waste Segregation and Recycling Planning

Demolition and site clearance debris needs sorting from the outset, not bundled together and dealt with later.

Asbestos waste, general demolition material, and recyclable material like brick, timber, and metal all follow different handling and disposal pathways. Planning this upfront also keeps a tight site from becoming physically unworkable, since there’s rarely spare space on an Inner West block to stockpile unsorted debris.

Site Preparation: Who Handles What and When

For homeowners, choosing experienced asbestos removal contractors in Sydney is particularly important when older materials are likely to be disturbed during renovation. The five steps above can be summarised into a simple planning sequence:

Step	Who Typically Handles It	Best Timing
Asbestos testing and removal	Licensed asbestos professional	Before any demolition or trade work begins
Access and equipment assessment	Demolition or excavation contractor	During initial site planning
Underground services check	Before You Dig Australia, followed by the site contractor	Before excavation is scheduled
Excavation and shoring	Licensed excavation contractor	After access and services are confirmed
Waste sorting and recycling	Demolition contractor	Ongoing, from first day on site

A Pre-Renovation Site Checklist

Use this checklist to confirm the key preparation steps have been addressed before work gets underway:

• Book asbestos testing before any demolition or trade work starts
• Measure site access, including overhead clearance, before booking equipment
• Lodge a Before You Dig Australia request ahead of excavation
• Confirm the excavation contractor has a Safe Work Method Statement in place
• Set up separate waste streams for asbestos, general debris, and recyclables from day one

Final Thought

None of these five steps are optional extras on an Inner West project. They are what determine whether the rest of the renovation runs smoothly or hits an expensive, avoidable delay a few weeks in.

Get the Groundwork Right

If you’re planning a renovation on a heritage-era Inner West property, it’s worth getting a site assessment from an experienced local team before finalising your build timeline, particularly if asbestos testing or tight access excavation is likely to be involved.
