Exploring rental registries across U.S. localities

Overview

Localities are increasingly using rental registries — customized databases containing information about rental properties — to gain a better understanding of their rental markets. These registries can be a vital source of reliable data that can help inform policy design, track outcomes, and even assist in coordinating responses during emergencies.

In this brief, we examine the rental registries of five different localities: Portland, ME; Cedar Rapids, IA; Jersey City, NJ; Oakland, CA; and Concord, CA. Each of these areas established their rental registries for a variety of purposes, including improving housing safety, enforcing rent control ordinances, and tracking evictions. The information presented in this brief is derived from interviews with staff members from each rental registry and other publicly available resources, such as city websites and ordinances, and was collected from late 2023 to early 2024.

Portland, Maine

Population: 69,104

Key features

  • Portland offers discounts on registration fees for properties that take certain steps to improve building safety.
  • The city conducts regular housing safety inspections to maximize the registry’s utility.

Registry objectives and design

In Portland, Maine, a 2014 house fire resulting in several deaths prompted the city to establish a rental registry with the aim of improving housing quality and safety. Maintained by the Permitting and Inspections Department, the registry was launched in 2017. Registration is mandatory for all residential rental properties, including short-term rentals. The registration fee is $50 per unit but may be lower if the property fulfills certain requirements to receive discounts, such as having a working smoke alarm in the building or including a no-smoking policy in its leases. Owners must update their information annually to renew their registration. The Permitting and Inspections Department sends annual renewal notices to owners to remind them to submit their information and offers classes on how to complete the registration. Owners may be subject to a $50 fine per unit if they do not register within a month of the deadline and a $200 fine per unit if they do not register within two months.

Cedar Rapids, Iowa

Population:  135,958

Key features

  • Cedar Rapids sends landlords automated yearly invoices for their registration fee to facilitate compliance.
  • Regular code inspections help the registry achieve its goal of improving housing safety.
  • The city requires landlords to complete a one-time training course on the inspection process and other important topics. 

Registry objectives and design

Cedar Rapids, Iowa, established a rental registry in 2010 to promote the health and safety of city residents. The Rental Housing Inspections Division within the Building Services Department maintains the registry, which mandates that landlords register all leased, rented, or let dwellings, excluding short-term rentals. Landlords pay annual registration fees ranging from $13 to $60 per unit, depending on the type of dwelling being registered. Failure to register rental properties on time results in an additional $50 or $100 added to each unit’s registration fee and the landlord permit fee, depending on the amount of time past due.

Jersey City, New Jersey

Population: 291,657

Key features

  • Jersey City does not charge a registration fee for properties with fewer than five units.
  • The registry system is accessible to the entire Housing, Economic Development & Commerce Department so that other divisions can assist in relocating tenants in emergency situations.

Registry objectives and design

Jersey City’s rental registry was established in the 1980s as part of the city’s rent control ordinance and is maintained by the Division of Housing Preservation within the Housing, Economic Development & Commerce Department. The ordinance requires all properties with five or more units and non-owner occupied properties with 1-4 units to be registered with the city annually during a specific registration period. During this time, landlords must report any tenancy changes, vacancies, and capital improvements made within the past year. Landlords of properties with five or more units pay a $10-per-unit registration fee, but there is no registration fee for properties with fewer than five units. Landlords must provide detailed information, including their contact information, the number of bedrooms in their property, tenant names and move-in dates, base and current rent amount, and the date and amount of the last rent increase for each unit.

Oakland, California

Population: 436,504

Key features

  • Oakland’s rental registry is part of its Rent Adjustment Program and is funded by the annual Rent Adjustment Program fee.
  • Instead of fines, landlords who fail to register face restrictions on their ability to increase rent, respond to tenant petitions, and evict.
  • In the future, the city aims to establish a portal for tenants to view registry data.

Registry objectives and design

In 2023, the City of Oakland, CA, launched its rental registry to shift from passive to active enforcement of the city’s rent control ordinance, known as the Oakland Rent Adjustment Ordinance. This ordinance was established in 1980 and created the Rent Adjustment Program (RAP). The RAP office’s primary responsibility is to enforce rent control in Oakland. While the city originally relied on tenant petitions to identify illegal rent increases and evictions, it hoped that establishing the rental registry would allow it to recognize rent control violations independently. The rental registry is maintained by the RAP office within the Housing & Community Development Department. Registration is mandatory for all units covered by the Rent Adjustment Ordinance (which includes multifamily buildings constructed before 1983) and the Just Cause for Eviction Ordinance (which includes any rental unit not newly constructed within the last ten years). RAP hosts regular virtual workshops to demonstrate how to complete registration and has also conducted outreach to landlords via email blasts and by attending stakeholder engagement events.

Concord, California

Population: 122,315

Key features

  • Concord exempts buildings with fewer than four units from mandatory registration.
  • The registry team works with an external contractor to collect registration data.
  • Concord’s City Council reviews an annual report based on registry data that informs housing policy.

Registry objectives and design

Concord, CA, rolled out its rental registry program in 2021 to meet the City Council’s need for more accurate and detailed data on rents, displacement, and evictions. The city was already operating the Residential Tenant Protection Program, which required landlords to provide relocation assistance for no-fault evictions and required minimum lease terms, but it was relying on poor quality data from CoStar and Craigslist to inform the program. The registry, managed by the Housing & Community Services Division, provided new high-quality data for the program. In the spring of 2024, a few years after the registry was created, the City Council passed a Rent Stabilization and Just Cause for Eviction ordinance informed by findings from the rental registry data.
