The building, in the grounds of St Enoch's Church in the centre of Alexandra, houses Central Otago Reap, social service agencies and arts and crafts groups.
The complex cost $2.6 million and opened in February last year.
The Vincent Community Board agreed this week to grant $5000 to the community house trust to carry out a feasibility study on expanding into the neighbouring property.
Trust chairwoman Bernie Lepper said the feasibility study would look into buying the neighbouring house and property with a view to using the site for car parking and other options.
Some of the community house's fulltime tenants rented 12 of the existing parks and if any of the meeting rooms in the building were being used, the house's car park was full and people had to park outside the facility.
''On a busy day, the overflow appears to take up all local public car-parking space,'' she said.
The trust would be focusing on increased occupancy of the building's casual spaces and as patronage of those areas increased, there would be more pressure on car parking.
The feasibility study would look at using all the neighbouring site for car parking, as well as the option of retaining and redeveloping the building which was on that site.
Board member Stu Millis said the trust must already have a fair idea of what it wanted, without needing a feasibility study.
Mrs Lepper said the feasibility study would look at all the different options, including the cost of rates of the adjoining property and what it would cost to remove the house that was on the section.
The neighbour had advised the trust he wanted to sell his property.
Board member Barrie Wills said parking was becoming more of an issue in the town - ''I'd dread to see a parking building needed.''
Central Otago District Council chief executive Phil Melhopt said if there was pressure on parks, the council needed to enforce parking restrictions.
Council property and facilities officer Tara Bates said there was $3000 unallocated in the Vincent general grants account, which could be used to part-fund the request.
The remaining $2000 could be funded from the Alexandra general development account, which was increased by $125,000 last year - the proceeds from the sale of the former Plunket building, which was owned by the council.
