ADUs in New Haven may be rented to non-owner tenants because New Haven did not opt out of CT PA 21-29 (CGS Section 8-1c). Long-term rentals are subject to New Haven's housing code inspection program administered by the Livable City Initiative (LCI), the Connecticut Landlord-Tenant Act (CGS Chapter 830), and New Haven's Fair Rent Commission under CGS Section 7-148b. Short-term rentals under 30 days face heavier regulation: New Haven has adopted Zoning Ordinance restrictions on short-term rentals (Airbnb-style transient lodging) in residential districts, and state lodging tax under CGS Section 12-407 applies.
New Haven ADU rental operates in two distinct tracks. Long-term (30 days or more): the property must comply with New Haven's housing code, administered by the Livable City Initiative (LCI), which conducts proactive inspections of rental units and responds to tenant complaints. Habitability requirements include heat, hot water, working appliances, smoke and CO alarms compliant with the Connecticut State Fire Safety Code (CGS Section 29-291 and the adopted IFC), structural soundness, pest-free conditions, and lead-safe conditions (lead paint disclosure and abatement requirements apply to pre-1978 housing under federal and Connecticut law, with New Haven's older Yale-area housing stock heavily affected). Tenancies are governed by the Connecticut Landlord-Tenant Act (CGS Chapter 830, Sections 47a-1 through 47a-74), which caps security deposits at two months' rent for tenants under 62 and one month for tenants 62 and older (CGS Section 47a-21), requires landlords to deposit security in an interest-bearing escrow account, prescribes lease and eviction procedures through the New Haven Housing Session of Superior Court, and prohibits retaliatory and discriminatory practices. New Haven operates a Fair Rent Commission under CGS Section 7-148b with authority to hear whether rents are 'harsh and unconscionable' and to order rent reductions or refunds. PA 23-207 expanded just-cause eviction protections in larger municipalities including New Haven for tenants who have lived in a unit for one year or more (CGS Section 47a-23c). Short-term rentals (under 30 days): New Haven has been more restrictive than many Connecticut municipalities, with Zoning Ordinance provisions limiting short-term transient lodging in residential districts and requiring compliance with hotel/bed-and-breakfast use standards where permitted. Yale's large student and visitor population creates an active Airbnb market, particularly during graduation, parents' weekends, and Yale-Harvard football weekend; operators must verify district permission before advertising. Connecticut state lodging tax under CGS Section 12-407 (15 percent on stays under 30 days) applies. Federal and state income tax obligations apply to all rental income.
Housing code violations under LCI inspection: notice of violation, civil penalties under CGS Section 7-148, and possible order to vacate if conditions are unsafe. Security deposit violations under CGS Section 47a-21: tenant can recover double damages plus attorney fees in New Haven Housing Session of Superior Court. Retaliatory eviction under CGS Section 47a-20: tenant defense and damage recovery. Fair Rent Commission complaints under CGS Section 7-148b: commission may order rent reduction or refund. Short-term rental in a zone that does not permit transient lodging: New Haven zoning violation under CGS Section 8-12 with civil penalties and injunctive relief in New Haven Superior Court. Lead paint disclosure or abatement violations: enforcement under Connecticut public health statutes with mandatory remediation.
