Condominium conversion and tenant protections

When your apartment building becomes condominiums, this is the chapter that decides how long you may stay, what rent increase is allowed in the meantime, and whether you get the first chance to buy your own unit. Elderly and disabled tenants get 18 months. Waiving any of it in a lease is void. The full statutory text, hosted for reference.

N.H. Rev. Stat. Ann. Ch. 356-C RSA 356-C:1 – 356-C:11 10 Sections in force 1 repealed
What this means for homeowners

If your landlord is turning your building into condominiums, this chapter — ten sections of it still in force — is the one that protects you. It sits on top of registration under the Condominium Act or the Land Sales Full Disclosure Act — RSA 356-C:2, III requires a conversion subject to this chapter to be registered under one of them notwithstanding any exemption in those chapters, unless the Attorney General exempts it.

“Conversion” is defined broadly at RSA 356-C:1, II: a change in the character of residential real property from a rental to an ownership basis, and “A condominium, stock cooperative or other similar arrangement shall be deemed ownership in character.” The chapter does not care what the arrangement is called.

Whether the chapter reaches your building

RSA 356-C:2, I(a) is the size test, and it has an anti-avoidance clause built in. The chapter does not apply to the conversion of a building, building complex or manufactured housing park having 10 or fewer dwelling units — but if a property with more than 10 units is converted in stages of 10 or fewer at a time, the chapter applies to that conversion anyway. Splitting a 40-unit building into four rounds of ten does not escape it.

Paragraph I(b) excludes nursing homes, dormitories, boarding houses, motels, hotels, units normally occupied by transient persons for 3 months or less, and units occupied seasonally for fewer than 6 months of the year. Paragraph I(c) excludes a dwelling unit that is individually owned but has been rented. Paragraph II carries the 1983 transitional rules: the chapter does not reach a conversion registered, recorded or formally offered before 22 June 1983, but it does reach one whose registration application had been filed and not yet granted by that date, to the extent set out in RSA 356-C:3, II; 356-C:5; 356-C:8 and 356-C:9 — and for that narrow class RSA 356-C:3, II(c) gives 90 days, not 270.

The notice, and the clocks it starts

RSA 356-C:3 is the heart of the chapter. No conversion may be effected until the owner has mailed each tenant, by registered mail, return receipt requested, a notice of intent to convert — sent no earlier than 120 days before the application for registration is filed — containing twelve specified items. A second notice goes out after registration, and the two may be combined if registration came first. If the owner does not apply for registration within 120 days of mailing, RSA 356-C:3, III makes the notice void.

Four of the twelve items are the ones tenants need:

Time to stay. Item (7): a tenant residing in the building when the notice is received has no less than 270 days from receipt, or until the 60-day exclusive purchase period expires, whichever is later, before being required to vacate — and a lease giving a longer term of occupancy still runs to its end.

Elderly and disabled tenants get far longer. Item (8): a tenant who is elderly or disabled when the notice is given has at least 18 months from receipt before being required to vacate, on showing that they qualify. RSA 356-C:1, IV defines an elderly tenant as one who is 65 years of age or older; paragraph III defines a disabled tenant as one receiving aid to the totally and permanently disabled from the state division of human services, social security disability benefits, or total disability benefits from the department of veterans affairs.

You can leave early without penalty. Item (10): notwithstanding any obligation in a lease to the contrary — except one entered into before 22 June 1983 — the tenant may terminate the tenancy without penalty or liability on giving the owner at least 30 days notice.

Item (12) is the rent-increase brake that the Condominium Act also refers to: if there is a rent increase, other than one permitted by RSA 356-C:6, I(a), the application for condominium conversion may not be made until 3 months after the increase. RSA 356-C:4 requires the RSA 356-C:3, I notices to be filed with the Attorney General at least 10 days before they are mailed to any tenant.

One limit worth knowing: RSA 356-C:3, IV withholds the chapter’s protections from anyone whose tenancy begins after the notices are served, if they were given written notice of the impending conversion before signing.

First refusal on your own unit

RSA 356-C:5 gives a tenant entitled to notice an exclusive right to contract for the purchase of the unit they occupy, provided the unit is to be retained without substantial alteration in its physical layout. The tenant must be given all the documents provided to the general public or to any other tenant as part of the offering, and has 60 days from receipt of the sales documents to exercise the right. It expires earlier if the tenant voluntarily gives notice terminating the lease or vacates.

Paragraph II is the remedy, and it is a strong one: failure to comply “shall render a sale to any person or entity other than the tenant voidable at the option of the tenant”, so long as the tenant exercises that option before giving notice of termination or vacating.

Eviction: six grounds, and a rent-increase cap

Once the notice has been served, RSA 356-C:6 closes off every other reason to evict. The tenant may be evicted only for: non-payment of rent or other reasonable charges (I); failure to comply with material terms of the lease, after written notice of the failure and a reasonable opportunity to comply (II); damage to the unit beyond reasonable wear and tear, not repaired within a reasonable time (III); repeated conduct disturbing the peace and quiet of other tenants (IV); expiration of the notice period (V); or, where the longer elderly-or-disabled period was the basis, that qualifying tenant no longer being in residence (VI).

Paragraph I(a) caps the rent in the meantime. No owner may charge, and no tenant is liable for, any rent increase other than one based on the unit’s pro rata share of increases in insurance, fuel oil, gas, electricity, water or sewer costs, real property taxes, and maintenance and operational expenses that directly or indirectly benefit the tenant. Two increases are prohibited outright: assessments against the unit for improvements to the converted property, and increased tax assessments due to the conversion itself. In other words, the tenant does not pay for the landlord’s conversion.

Paragraph I(b) is a safety net in court. In any non-payment action based on a tenant’s failure to pay an increase, the court determines how much of the proposed increase is permissible and gives the tenant 30 days to pay that sum — and if the tenant pays within the 30 days, the eviction action is dismissed.

You cannot sign these rights away

RSA 356-C:7 is unambiguous: no lease or rental agreement, oral or written, may contain a provision by which the tenant prospectively waives any right under this chapter, and any such waiver “shall be deemed contrary to public policy and shall be unenforceable and void”. RSA 356-C:8 is the anti-circumvention section, and it is the one the $1,000 floor below attaches to: no owner or agent, alone or with others, may circumvent or attempt to circumvent the RSA 356-C:6 eviction protections, or wilfully cause a tenant to vacate or be evicted without good cause in contemplation of conversion before the notices issue. It ends with a savings clause — nothing in the chapter makes it unlawful to evict at any time on one of the RSA 356-C:6 grounds.

Damages, and the risk of a frivolous claim

RSA 356-C:9, I doubles the damages. An owner or agent who violates any provision of the chapter is liable to any tenant injured by the violation in an amount equal to double the actual damages suffered — and for a violation of RSA 356-C:8, actual damages or $1,000, whichever is greater. A tenant who prevails is entitled to reasonable attorney’s fees and costs. Paragraphs II and III make one household member’s action, or a good-faith settlement with one member, a bar to actions by the others.

RSA 356-C:10 runs the other way. A tenant who refuses to pay a permissible rent increase under RSA 356-C:6, I(a), or who brings an action under RSA 356-C:9, I, on grounds a court finds frivolous or brought solely to harass, is liable to the owner for the owner’s costs, including reasonable attorney’s fees.

Once the conversion is complete and you own a unit, the law that governs the community is the Condominium Act — and RSA 356-B:56 sets out the special provisions for a conversion condominium, including that the RSA 356-C notices form part of the registration application. The rest of the tab is on the New Hampshire HOA laws hub.

RSA 356-C:6 Eviction Protection

Once notice has been served on the tenant in accordance with RSA 356-C:3, I or II, the tenant shall not be evicted from his dwelling unit except upon the following grounds:
