Western Sydney
Private building certifier in the Penrith City Council area
CertifiBuild certifies new homes, extensions and outbuildings across Penrith. Two things shape most local projects. Penrith has several planning instruments still in force, so neighbouring lots can follow different rules. Flooding from the Nepean River is the other big factor.

Local rules
What shapes approvals here.
Many layers of planning rules
The main plan is the Penrith Local Environmental Plan 2010 (LEP). Several older instruments still apply in parts of the city. Penrith LEP 1991 covers heritage conservation, LEP 1998 covers some urban land and rural lands fall under LEP No. 201. The Penrith Lakes Scheme has its own state policy, as does the employment area in Western Sydney. St Marys also has a regional plan, along with three Interim Development Orders. You cannot tell which apply just from your address.
Design rules and chapter numbers
The Penrith Development Control Plan 2014 (DCP) sets the detailed design rules across most of the city. At Kemps Creek, within the Mamre Road Precinct, a separate DCP made by the state in 2021 takes its place. Council also gave the Penrith DCP chapters new numbers from 1 October 2026. A few of the new numbers clash with old ones. If your designer's notes cite a chapter, check both its title and its number.
Nepean floodplain
Penrith lies on the Nepean River, in the valley of the Hawkesbury-Nepean. Flooding here can involve more than a minimum floor level. Your council planning certificate states whether it is a flood control lot. A complying development certificate (CDC) is still possible on such a lot. The design must comply with the flood rules in the state code.
Mostly detached homes
In Census 2021, separate houses were 78.3 per cent of all lived-in homes. Werrington Downs had its final lots released in 1981. Owners there often ask about second storeys, patios and extensions at the back.

Local know-how
Penrith projects, from the valley to the newer estates
Emu Plains
Emu Plains started as a government farm in 1819, and the trains came in 1868. Old township buildings now sit beside later suburban houses and some villas. Common jobs are rear additions, new garages and roofs over outdoor areas. Close to the station, a defined precinct is covered by a separate DCP chapter. It fixes where cars can enter and asks for noise-aware design beside Lamrock Street. Check that map before you settle a driveway or window layout. Heritage listing does not follow from an old address. The council's heritage map decides that.
Glenmore Park
Glenmore Park was built in stages from 1990, and each stage has its own design chapter. In Stage 2, many homes have a shared driveway or a garage off a rear lane. Your main outdoor area may also have been planned with the block. So before a pool, alfresco or garage conversion, we pull up the original site plan. A new structure can eat into space that helped the home gain its first approval.
Jordan Springs
This planned estate is mainly detached houses, so typical work is pools, sheds and alfrescos. In December 2025, a revised Central Precinct plan was finalised. Developer design guidelines also apply, and the developer must approve plans before they are lodged. That approval does not count as a building approval. In Jordan Springs East, some planning certificates carry notes about filled ground and footing design. Obtain your lot's certificate and engineering advice before you pick a pool or roof structure.
Mulgoa
Mulgoa grew out of farms, vineyards and orchards, and separate houses are almost the only dwelling type. Typical projects are rural sheds, garages, verandahs and additions. Mapped parts of the valley have their own planning rules. These protect historic views. They also favour buildings grouped mid slope, away from ridges and creek banks. Even a driveway, gate or new planting can matter. A granny flat or dual occupancy also depends on zoning and sewer access.
Why Penrith owners and builders choose CertifiBuild
We work across Penrith's town centres, estates and rural valley. We know how the local chapters apply on real sites. Early on, we read the council maps and planning certificate for your lot, then explain which approval pathway fits. We answer questions promptly and book inspections to match your builder's program. Our focus stays on houses, granny flats, sheds, pools and other Class 1 and 10 work. That keeps our advice practical.

Local questions
Questions we hear in this area.
No two lots are alike. Share your address and we will review the maps that cover it.
All council areasMy neighbour’s lot follows different rules to mine. How is that possible?
Because Penrith’s planning rules have built up in layers over the years. The Penrith Local Environmental Plan (LEP) 2010 is the main one, yet several older LEPs still cover heritage, some urban land and rural lands. On top of that, state policies govern an employment area and the Penrith Lakes Scheme, St Marys has its own regional plan, and three older interim orders remain. Each can cover different land, so two lots side by side may answer to different plans. Your address alone will not tell you. We read your planning certificate and confirm which set covers your lot.
Does the Penrith DCP cover the Mamre Road Precinct?
No. At Kemps Creek, land inside the Mamre Road Precinct follows a separate development control plan (DCP) that the state made in 2021, and it replaces the Penrith DCP 2014 there. Elsewhere in the city, the Penrith DCP 2014 generally still holds the detailed design rules. Also note that council gave the Penrith DCP chapters new numbers from October 2026, and a few new numbers clash with old ones. If your designer’s notes cite a chapter, check its name too. We confirm the right DCP for your lot early, before any setbacks are read.
Does a flood affected lot rule out a CDC?
Not automatically. In Penrith, a flood control lot can still use a complying development certificate (CDC), provided the plans satisfy the flood rules in whichever state code is used. Your planning certificate will say if the lot carries that flood status. Penrith lies along the Nepean River, in the wider Hawkesbury-Nepean valley, so flood planning here can involve more than setting a minimum floor level. If the design cannot meet the code’s flood rules, a development application (DA) to council is the alternative. Send us the planning certificate before floor levels are drawn.
