Some 94 matters are either under investigation, subject to enforcement actions or ongoing monitoring in Goulburn Mulwaree.

They range from unapproved residences, including 'granny' flats, dumped vehicles, environmental incidents and unauthorised vegetation clearing, earthworks or construction.

One allegation involves the home of a former Goulburn City mayor.

Councillors heard at their meeting on Tuesday that a policy based on "co-operative compliance," whereby planners tried to achieve an acceptable outcome, was not working.

Environment and planning director Scott Martin described it as "ineffective," while general manager Warwick Bennett said the council needed to implement a harder line.

"There would be very few people who wouldn't understand that they need to get approvals to do building works. The law has just been flouted," he said.

"I'll be putting a position paper up to the council very soon saying that we need to go harder with fines from the word go."

Increased fines would fund more monitoring resources within the planning department.

Mr Bennett told the meeting that the "natural justice" method wasn't sending the right message that the actions were "unacceptable."

Councillors also decided to advise real estate agents, solicitors and conveyancers that "weekenders" were not a permissable use.

Mr Martin said landowners and the real estate industry were exploiting the area's reasonably priced land and rural lifestyle. Marketing techniques often spruiked "weekenders" on a property but this was not a defined planning use.

But the unlawful works are springing up in urban and rural areas.

His report detailed 29 instances of alleged unauthorised work.

They included 555 Forest Siding Road, Middle Arm, where a shed has been used for residential purposes, vegetation cleared and a "non-compliant" wastewater system installed. The council is prosecuting the owner in the NSW Land and Environment Court.

Planners are also investigating a Hume Highway, Marulan site potentially being used as a landfill. At another nearby property, they alleged unauthorised earthworks and structures had occurred. In addition, a clean-up order will be issued to a Dorsett Road property owner for "unsightly premises and hoarding of vehicles."

At Kooringaroo Road, Gundary, officers have served a notice of proposed order on camping grounds. Close by, on McLaughlin Road, investigations are underway into noise complaints and alleged use of the site for motor vehicles.

At Marulan, Mr Martin said a stop work order had been issued for work on former 24-hour service station. It was allegedly being converted into a food premises and planners were concerned about structural integrity.

Two weeks ago, his officers were called to a Boxers Creek Road property where tyres were burning in a watercourse. Mr Martin said it was "obvious" it wasn't the first time it had occurred and a clean-up notice had been issued.

While there, officers were alerted to stored chemical containers nearby, on Stockade Lane. Further inquiries revealed an unauthorised dwelling, structures and wastewater system, he said. A cease order has been issued.

In Goulburn, former Goulburn City Mayor Tony Lamarra has been issued with a stop-work order on his Church Street home. Planners said the 'unauthorised work' lacked consideration for the heritage conservation area. Compliance action has been halted, pending a development application.

Mr Lamarra said this would soon be lodged but he rejected suggestions he had willfully flouted laws. He told The Post he had removed a front garage because it was dangerous and after liaising with the council understood he could do further work provided it didn't undermine structural integrity. Mr Lamarra said this was more of a misunderstanding by both parties.

Elsewhere in Goulburn, planners were this week authorised to clear cars from a laneway off a Cowper Street address.

"The next step is to remove cars from the front yard," Mr Martin said.

The council claimed this had been ongoing for many years, that it was "constantly" impounding vehicles, which were also impeding neighbour access, and the lack of downpipes and guttering on a house was causing runoff to adjoining houses. "Multiple rectification orders had been served.

Meantime, the owner of Avoca Street apartments has mounted Land and Environment Court action against the council over a demolition order. The latter claimed that underfloor car parking spaces had been converted for residential use, contravening planning consent in the flood-prone area.

"We are trying to work out the basis of that challenge and it won't be the last you hear of this one, unfortunately," Mr Martin said.

In Mary Street, Goulburn, RSPCA officers and council rangers had visited an address where "numerous cats" were housed and odour generating waste had accumulated.

In Goldsmith Street, a demolition order has been issued for demolition of a granny flat and in Chantry Street, for an unauthorised shed in a heritage conservation area.

Mr Martin said it was by no means an exhaustive list and the number was expected to grow.

"What we're saying is there's some significant deterrence here and it's something we feel is appropriate...because it's a big impost on our resourcing and staff time," he said.

"We're also finding the community is less tolerant of...unauthorised works."

He told the meeting that fines were a last step and under the policy, owners were given the chance to explain their actions.

Mr Martin argued education was key but so too was advising real estate agents that properties shouldn't be marketed as having "weekenders."

Councillors also agreed to change section 10.7 planning certificates reminding land buyers to obtain appropriate approvals before undertaking work.

"We don't want people coming to Goulburn Mulwaree and thinking they can do anything they want," Mayor Bob Kirk said.
