The Columbia Gas explosions in Lawrence, Andover and North Andover raise numerous questions for landlords. Tenants are going for weeks or months without gas and had some time without electricity. Should landlords offer rent abatements and if so, how much and for how long? Should they reimburse tenants for out of pocket expenses? Should they refuse to do either of these things and tell tenants to put claims in with Columbia Gas and with their renter's insurance? Should they serve notices to quit when tenants don't pay their rent? Co-chairs of the Residential Landlord/Tenant Section, Ken Krems and Emil Ward, will lead an open discussion of these and related issues.
