Cost Rental vs HAP vs Social Housing in Ireland
A side-by-side comparison of Ireland's three main housing support schemes. Eligibility, income limits, how rent is calculated, and which scheme is right for your situation.
Three Housing Schemes, Three Different Audiences
Ireland's housing support system has three main pathways. Each targets a different income group and works differently.
- Income limit EUR 59k to 66k net
- Rent savings 25%+ below market
- Landlord AHB / LDA
- Waiting list No (per-development)
- Income limit Social housing thresholds
- Support Rent limit per area
- Landlord Private landlord
- Waiting list Yes (housing list)
- Income limit Lowest thresholds
- Rent % of income (differential)
- Landlord Council / AHB
- Waiting list Yes (often years)

What Is the Difference Between Cost Rental and HAP?
The biggest difference is who the scheme targets and how rent is set. Cost rental is for middle-income earners (net income up to EUR 66,000 in Dublin) who pay a fixed rent based on building costs. HAP is for lower-income households on the social housing waiting list, where the council pays rent directly to a private landlord and you contribute a smaller differential rent based on your income.
With HAP, you find your own private rental and the council tops up your rent. With cost rental, you apply for a specific development and the home is purpose-built and managed by an AHB or the LDA. Cost rental tenants have more predictable rent increases (capped to inflation) while HAP tenants are exposed to market rent increases, though Rent Pressure Zone caps may apply.
What Is the Difference Between Cost Rental and Social Housing?
Social housing is for the lowest-income households and provides heavily subsidised rent (typically 10% to 20% of assessable income). Cost rental targets the group above social housing: working people who earn enough to be disqualified from social housing but not enough to afford private rents.
Social housing tenants pay differential rent that changes with their income. Cost rental tenants pay a fixed rent that reflects the cost of the building, regardless of their personal income. Social housing has very long waiting lists (often 5 to 15 years in cities). Cost rental has no standing waiting list; applications are per-development.
Can You Switch Between Schemes?
If you are currently on the social housing waiting list or receiving HAP, you are generally not eligible for cost rental. However, if your circumstances change (income increases above social housing limits, for example), you may become eligible for cost rental instead. Each provider sets its own rules, so check directly with the AHB or LDA managing the development you are interested in.
If you are in a cost rental home and your income drops below social housing thresholds, you would not be moved out, but you could apply for social housing or HAP separately if you wished.
