5 ideas for a cottage court – building a rental or for-sale unit

Lack of affordable housing is causing the rising trend of smaller homes. According to Fortune, half of all households in the country can’t afford a normal starter home. Hence the resurgence of cottage courts (a.k.a. bungalow courts) as a charming and practical solution—a type of small-scale community housing that promotes neighborly connections and efficient land use.

The post focuses on offering creative and cost-effective ideas for building cottage courts that can serve as affordable rentals. Use it as a checklist or as an inspiration.

You can take any of our accessory dwelling unit plans to get started. Our ADU Viewer is a great tool to show your neighbors they should have no privacy concerns.

The five ideas that will be covered in the post include:

  1. Planning for shared open spaces
  2. Eco-friendly materials and methods
  3. Optimized floor plans
  4. Use of prefabricated components when building
  5. Unexpected architectural styles

Let us start by discussing common challenges that prevent a cottage court model from becoming a solution to missing middle housing.

Ideas for a modern cottage court - several models

Why cottage courts are a rarity

Before we deal with the pool of ideas, let us talk about common challenges.

Building cottage courts presents unique challenges, especially when trying to keep them affordable. Some common issues are zoning, infrastructure, financing, cost-efficiency, privacy concerns, and long-term maintenance.

Zoning laws in many areas may not allow for the development of cottage courts, particularly in residential zones that require larger lot sizes or prohibit multiple units on a single parcel.

Before designing your cottage court, research local zoning regulations. Think creatively – sometimes it is better to subdivide first before designing a cottage court.

If you see any roadblocks, consider applying for variances. Lobbying your city council for zoning changes that support small, clustered housing developments is also encouraged.

Providing adequate infrastructure (roads, sewage, water, and electricity) for multiple units on a single lot can be expensive, particularly in areas without existing utilities.

To face the issue straight on, cluster the units closely to minimize the infrastructure needed and consider green infrastructure solutions like shared septic systems or solar power. Always have a backup plan for expensive requirements like fire sprinklers and driveways.

Parking requirements can be challenging for cottage courts. Here is how cottage courts typically address parking requirements:

  1. Grouped parking areas rather than individual driveways
  2. A mix of on-street and off-street parking options
  3. Careful placement of parking to maintain the pedestrian-friendly nature of the development

If the lot has limited street frontage, think about optimizing the number of parking spaces for residents and occasional guests early on.

Why it is so difficult to finance a cottage court

Securing financing for a cottage court can take time, as lenders may be unfamiliar with this type of development and view it as a higher risk.

Work with lenders who specialize in small-scale or nontraditional housing developments and explore alternative funding options, such as local credit unions, community land trusts, or cooperative ownership models.

If you are looking for financing, you need a lender who speaks the right language and knows construction costs.

Two angles to keep cottage courts affordable

If  affordability is the goal, keeping costs low while maintaining quality can be tough, especially with rising construction costs and land prices.

Use permit-ready plans and cost-effective prefab construction methods to keep land costs down.

Cottage courts are inherently dense developments, which can lead to concerns about privacy and overcrowding among residents.

To balance density and privacy, design the layout carefully to ensure each unit has adequate privacy, using landscaping, fencing, and thoughtful placement of windows and doors. This is also one reason we are not suggesting using modular construction—this construction type is less easy to customize.

Managing multiple rental units on a single property can be complex, especially when it comes to maintenance, tenant relations, and communal space upkeep.

Establish clear management structures and responsibilities from the outset, whether through a property management company, homeowners’ association, or another entity.

Addressing these challenges early on can help ensure a cottage court development is successful, sustainable, and affordable.

Maximize Shared Outdoor Spaces

Communal outdoor areas in a cottage court, such as shared gardens, picnic areas, or fire pits, foster a sense of community while keeping costs low.

Design the cottage court around a central shared green space that serves as a communal gathering area, a perfect spot for a neighborhood party. This shared public space can include features such as a fire pit, seating areas, and gardens. Think about what could be done here at Halloween or Christmas.

The cottages should be arranged to face this space, encouraging interaction among residents. This layout not only fosters community but also enhances the development’s aesthetic appeal. The design can incorporate native plants and landscaping to minimize maintenance and support local biodiversity. Successful cottage courts emphasize a strong indoor-outdoor connection through large windows and French doors, landscaping, and patios.

Concentrate on creating an optimal site layout that maximizes the use of available land and keeps the community happy:

  1. Design a central shared courtyard as the focal point of the development
  2. Arrange cottages to face the courtyard, promoting interaction among residents
  3. Ensure proper spacing between units for privacy and to meet local zoning requirements
  4. Incorporate efficient parking solutions, such as shared parking areas or alley access
  5. Plan for pedestrian-friendly pathways and lighting for safety and accessibility
  6. Use drought-resistant landscaping in common areas
  7. Implement rainwater harvesting systems for irrigation if budget allows

Emphasize Sustainable and Eco-Friendly Materials

Using sustainable materials in cottage court construction is an emotional benefit and a cost-saving tip. 

These choices can reduce long-term maintenance costs and appeal to eco-conscious renters.

To create eco-friendly cottages, use sustainable building practices and materials. This could include using locally sourced materials, energy-efficient designs, and renewable energy sources such as solar panels. Each cottage can be designed with green roofs or rainwater harvesting systems to promote sustainability. Additionally, implementing shared facilities for laundry, storage areas, gardening, and recycling can reduce the overall environmental footprint of the cottage court while encouraging community participation in sustainability efforts.

For passive solar design, cottages should be oriented to maximize southern exposure for natural heating in winter and use roof overhangs and awnings to provide shade in summer.

Aim for a High-Performance Building Envelope

  • Use advanced framing techniques to reduce thermal bridging
  • Install high-quality insulation in walls, floors, and roofs
  • Employ air sealing measures to minimize drafts and heat loss
  • Install energy-efficient windows and doors with low U-factors

Proper insulation helps maintain comfortable indoor temperatures year-round. In winter, it prevents heat loss, keeping cottages warm. In summer, it reduces heat gain, keeping interiors cool.

This means smaller, more efficient HVAC systems ( a short-term benefit to builders) and lower utility costs for residents (a long-term benefit).

Insulation costs less than 2% of the overall construction budget but plays a huge role in long-term cost efficiency: It prevents conditioned air from escaping, reduces the workload on HVAC equipment, and thus extends the lifespan of heating and cooling systems. It is not to be ignored.

Proper insulation, when combined with air sealing measures, goes even further: it minimizes air leakage and drafts, prevents moisture issues (which means no mold), and improves overall comfort for residents.

We typically use high-efficiency heat pumps for heating and cooling with programmable or smart thermostats in each unit. While radiant floor heating across the whole unit may be excessive, consider it for bathrooms for improved comfort and efficiency (with a timer).

Do not forget about energy-efficient lighting and appliances

  • Use LED lighting throughout the cottages and common areas
  • Provide Energy-Star-certified appliances in all units
  • Install occupancy sensors for exterior and common area lighting

Even a tiny, affordable home must meet energy efficiency requirements, which these days means installing a heat recovery ventilation system (a.k.a. ERV) to maintain air quality while conserving energy.

There are no requirements for PV systems on smaller homes, but if you are considering installing carports, their roof may be a perfect spot for solar panels.

Optimize Small Living Spaces for Comfort

When designed right, little cottages feel spacious and functional despite their size.

Incorporate Flexibility with Prefab Construction

Every line item matters when you are thinking return on investment (ROI). Here is what helps:

  • Using standardized, repeatable designs to streamline construction and reduce costs
  • Employing efficient building methods, such as panelized construction
  • Selecting durable, low-maintenance materials to reduce long-term maintenance expenses

 

Create a Variety of Cottage Styles to Attract Diverse Renters and Buyers

We do not need to say that offering different cottage sizes is super important to cater to a range of renters, from singles to small families. A mix of sizes can increase the marketability of the rental units and be a great solution for first-time homebuyers if you are building for-sale units.

One thing is a must, though: maintain a cohesive look for the entire court.

Incorporate a variety of unit sizes and configurations to cater to different demographics, such as singles, couples, and small families. They can be starter homes and homes for those who are retiring and downsizing. For example, some cottages could be designed as studios and one-bedroom units, while others could have three bedrooms. This flexibility allows for a diverse community and can adapt to changing family needs over time. The units can also feature innovative storage solutions and multi-functional spaces to maximize usability within smaller footprints.

Offer a mix of unit sizes (typically 500-800 sq ft) to cater to different needs.

Maximize livable space within compact footprints.

Include porches or patios to extend living areas and connect to the shared courtyard.

You may think that a traditional cottage style would be the most appropriate architectural style for a cottage court, but let us consider two other options: contemporary and Spanish (or Mediterranean, if you will).

Key features of a contemporary cottage court

A contemporary-style cottage court would blend modern architectural elements with the traditional cottage court layout.

  • Drought-resistant plants like olive trees, lavender, and bougainvillea
  • Large earthenware pots with colorful flowers or succulents
  • Decorative ceramic tile or terracotta pavers for walkways

With these Spanish-inspired elements, a cottage court can achieve a charming, Mediterranean-inspired atmosphere of sun-drenched family vacations while maintaining a cozy, community feel.

Legal support for cottage courts in California

Senate Bill 1123 (SB 1123), authored by Senator Anna Caballero and signed into law on September 19, 2024, enhances the Starter Home Revitalization Act of 2021 by streamlining the development of small-scale housing projects in California. Effective July 1, 2025, this legislation aims to increase affordable homeownership opportunities by simplifying the subdivision process for multifamily and certain single-family zoned properties.
 

Key Provisions of SB 1123

 
Expansion to Single-Family Zoned Vacant Lots:
The bill extends ministerial approval processes to vacant lots zoned for single-family residential use, allowing subdivisions into up to 10 parcels for housing development. Previously, such provisions applied only to multifamily-zoned properties.
 
Accessory Dwelling Units (ADUs) Exclusion from Unit Count:
If a local agency permits ADUs or Junior ADUs, these units will not count toward the 10-unit maximum for the housing development project, encouraging the inclusion of additional housing units.
 
Inclusion of Tenancy in Common:
The legislation recognizes tenancy in common arrangements as an eligible form of homeownership for projects developed under this act, broadening the spectrum of ownership models.
 
Minimum Parcel Size Adjustments:
The newly created parcels must be at least 1,200 square feet for subdivisions in single-family residential zones, ensuring appropriate lot sizes for development.

Height Limit Provisions:

Local agencies are authorized to impose height limits on developments in single-family zones, provided these limits are no more restrictive than existing zoning regulations.
 
 
SB 1123 facilitates the creation of affordable “starter” homes by expanding streamlined approval processes to include vacant lots in single-family zones and clarifying the treatment of ADUs.
 
This approach addresses California’s housing shortage by promoting modest-density infill housing projects, thereby enhancing access to homeownership for a broader demographic.

Appreciate the impact of a cottage court

One must recognize the potential impact of pocket neighborhoods on creating affordable and attractive rental properties. Why not create a beautiful place that gives the ambiance of a permanent family vacation?

There are several key benefits to living in a cottage court compared to a traditional neighborhood:

  • Sense of community: Cottage courts are designed to foster interaction and connection among residents. The shared central courtyard or green space serves as a focal point for community gathering and socializing.
  • Efficient use of space: Cottage courts use more land than traditional single-family developments, allowing for higher density while maintaining a small-scale feel.
  • Affordability: The smaller footprint (typically 500-800 square feet) can make cottage courts more affordable than larger single-family homes, appealing to first-time buyers, down-sizers, or those seeking lower-cost housing options.
  • Privacy with proximity: While fostering community, cottage courts still offer the privacy of detached homes, unlike apartments or townhouses.
  • Sustainability: Smaller homes are more energy-efficient and have a lower environmental impact than larger residences.
  • Diverse housing options: Cottage courts provide an alternative housing type that can serve various demographics, including young adults, small families, and seniors looking to downsize.
  • Walkability: Many cottage courts are designed as infill developments in urban areas, providing easy access to nearby amenities and services.
  • Reduced maintenance: Smaller homes and shared common spaces can mean less individual maintenance for residents compared to larger single-family properties.
  • Transition zones: Cottage courts can serve as effective transitions between single-family neighborhoods and higher-density areas.
  • Potential for innovative design: Cottage courts’ compact nature allows for experimentation with architectural styles and sustainable building practices.

These benefits make cottage courts attractive for those seeking a balance between community living and private home ownership, especially in urban or transitional areas.
