Private building certifier in Lithgow
CertifiBuild certifies extensions, granny flats, garages, sheds and pools in Lithgow. Many older streets close to the CBD sit in heritage conservation areas, and that usually decides the approval route first.

Lithgow: a valley town with heritage streets
Mostly older houses
At the 2021 Census, the Lithgow locality had 4,956 residents and 2,676 private dwellings. Among occupied homes, 81.7% were stand-alone houses, 13.4% semis or row houses, and 4.0% flats. Many homes date from the town's industrial past, from rows of workers cottages to more substantial houses, so original construction and later additions are worth checking before you plan new work.
Several conservation areas
Chapter 4 of the Lithgow Development Control Plan 2021 (council's detailed design rules) sets out heritage conservation areas across the centre and its fringe. Lithgow Main Street covers most of the central business district. Cook Street and Eskbank Street hold rows of single storey cottages from the late Victorian era. Hassans Walls Road has homes built for Small Arms Factory staff, and Inch Street sits beside Blast Furnace Park. In these areas, garages belong behind the building line, high solid front fences are out, and upper floors should not be readily visible from the street.
Subsidence
Subsidence Advisory NSW lists both a Lithgow and a Lithgow South mine subsidence district, so find out if your block is in either.
Typical work
Common projects and how they get approved
What owners build here
Lithgow's older housing stock produces steady renovation work. Most jobs adapt existing houses rather than build from scratch. Typical projects:
- Rear ground floor additions to cottages in heritage streets, kept out of the street view.
- Extensions and new rooms on detached houses outside the conservation areas.
- Granny flats on deeper lots, sized within the limits set by the local plan.
- Garden sheds, carports and garages, with the DCP tying total floor area to lot size.
- Pools and decks on falling land, where cut or fill deeper than one metre calls for extra evidence.
How approval usually works
Outside the conservation areas, a CDC (complying development certificate, the fast state code approval) can suit many Lithgow houses, sheds and pools when the site and drawings tick every code requirement. Inside a conservation area, most work needs a development application (DA) to council, supported by a heritage impact statement. Ahead of lodging, check the heritage map in the Lithgow Local Environmental Plan 2014. New buildings and extensions in a mine subsidence district also need Subsidence Advisory NSW to approve them, so check the map. On a heritage street, leave original face brick unpainted and do not lift the roof pitch to fit attic rooms. CertifiBuild checks the heritage and subsidence maps for your address at the start, then times inspections around your builder.

Local questions
Questions we hear about this suburb.
No two lots in Lithgow are the same. Give us your address and we will check every map that affects it.
See the council pageIs an upper floor allowed on a Lithgow heritage street?
Rarely. Where a conservation area has a single storey streetscape, the Lithgow Development Control Plan 2021 (DCP) accepts an upper floor only if it cannot readily be seen from the street. On Hassans Walls Road, where homes were built for Small Arms Factory staff, visible second storeys and roof conversions are ruled out. Rear ground floor additions are the preferred way to add space. Keep original face brick unpainted and do not raise the roof pitch for attic rooms. Work in these areas usually needs a development application (DA) lodged with council, backed by a heritage impact statement.
Is Lithgow in a mine subsidence district?
Parts of it are. Subsidence Advisory NSW lists two districts here, one named Lithgow and one Lithgow South, and whether your block sits in either depends on the exact address. Look it up on the state’s spatial viewer before you design. Inside a district, new buildings and extensions must also be approved by Subsidence Advisory NSW, an extra step on either a complying development certificate (CDC) or council application. Check the heritage map in the Lithgow Local Environmental Plan 2014 too, since many older streets near the centre are in conservation areas.
What is the shed size limit on a Lithgow town block?
It depends on lot area. Under the Lithgow Development Control Plan 2021 (DCP), urban lots under 900 square metres can carry up to 80 square metres of outbuildings in total. Lots of 900 square metres or more, but no bigger than 2,000, allow 100, and anything larger allows 120. Zone sets height. The DCP ties the total for sheds, garages and carports to lot size, so count existing structures first. Where cut or fill goes past one metre, extra supporting evidence is needed, and heritage conservation areas want any garage kept behind the building line.
