Mobile Home Park Rent Increase in New Brunswick

Mobile Home Sites Are Covered by the Same Act

Mobile home site leases in New Brunswick fall under the Residential Tenancies Act (R.S.N.B. 1975, c. R-10.2), alongside standard apartments and houses. The 3% statutory cap and six-month notice period apply to mobile home site rent. Section 25.4 governs these increases despite Section 11.1 and separately requires a standalone notice and a uniform percentage across the community or area.

Where mobile homes differ is in two specific provisions: the uniformity rule and a higher security deposit limit.

The Uniformity Rule Under Section 25.4

This is the provision that catches most mobile home park operators off guard. Section 25.4 of the Residential Tenancies Act requires that rent increases within a mobile home community must apply an identical percentage across all sites — either within the entire park or within the same distinct geographical section of it.

You cannot raise one tenant's site rent by 3% and leave the neighbour at the old rate. You cannot raise some sites by 2% and others by 3%. The increase must be uniform.

The practical effect is that any rent increase in a mobile home park is an all-or-nothing decision for that section. If you want to raise rent on one site, you must apply the same percentage increase to every site in the same section.

How the 3% Cap Applies

The statutory 3% cap (in effect through December 31, 2027) sets the maximum percentage increase per year. Since the uniformity rule requires the same percentage for every site, the cap effectively limits the entire park to 3% per year across the board.

If a park operator needs to exceed 3% for capital expenditure recovery — significant structural repairs or site infrastructure upgrades — the above-cap application process applies. The landlord must get written approval from a Residential Tenancies Officer before serving notice, and the maximum approval is 9%.

Notice Requirements Are Identical

Mobile home site rent increase notices require:

• Six full calendar months' written notice under N.B. Reg. 82-218 Section 11.1
• The notice must be a standalone separate document — not embedded in a lease renewal or combined with any other communication
• Required fields: tenant name, site address, current rent, proposed new rent, effective date, and landlord signature

Serve by personal delivery, ordinary mail to the tenant at the premises, or electronic transmission to the address given in the lease. Keep your proof of service in a compliance file.

The Higher Security Deposit Limit

Standard residential tenancies in New Brunswick cap security deposits at one month's rent, except week-to-week tenancies, which are capped at one week's rent. Mobile home sites are the exception — under Section 25.3 of the Residential Tenancies Act, the deposit for a mobile home site can be up to three months' rent.

The same provincial remittance rule applies: all deposits must go to the Security Deposit Fund managed by Service New Brunswick within 15 days of collection. Landlords cannot hold mobile home site deposits in personal accounts.

Tenant Challenge Rights

Mobile home tenants have 15 days after receiving a rent increase notice to apply for review under Section 25.4(3). A Residential Tenancies Officer must set aside a notice if the landlord fails to establish that the increase is uniform and the notice is a separate document.

If a park operator applies different percentages to different sites, every affected tenant has grounds for a challenge — and the officer must set aside any non-uniform notice.
