Thinking about adding a casita to your West Side property, but not sure where to start? You are not alone. Taylor Ranch and Paradise Hills sit side by side, yet the rules and process for accessory units are very different. In this guide, you will learn what is allowed in each area, how to check your lot, what permits to expect, and how much a project might cost. Let’s dive in.
Casita rules: Taylor Ranch vs. Paradise Hills
Inside Albuquerque city limits (Taylor Ranch)
If your property is inside the City of Albuquerque, casitas are allowed in many single-family zones with clear standards. The city’s rules set a maximum size of 750 sq ft, rear-yard placement, minimum 5 ft side and rear setbacks, a cap that limits the casita to 25 percent of the side plus rear yard area, and one off-street parking space. The City of Albuquerque also offers four free, permit-ready plan sets to help you move faster, and broad citywide ADU changes took effect on July 27, 2023. You can review the standards and resources on the city’s casita page and free plans page:

In Paradise Hills Special Zoning District
If your property is in unincorporated Paradise Hills, you are under the Paradise Hills Special Zoning District (PHSZD). The PHSZD ordinance treats accessory living quarters differently. It defines accessory living quarters as up to 500 sq ft, limited to one bedroom and one bathroom, with no kitchen, and states they cannot be rented or used as a dwelling unit. A structure with a kitchen may be treated as a separate dwelling and could require a Special Use Permit or variance. The PHSZD also applies separation and yard rules that vary by zone, and projects go through the PHSZD permitting process. Start with the PHSZD forms page and ordinance:

Can your lot fit a casita?
Key size and setback checks
- City lots: confirm the 750 sq ft maximum, 5 ft side and rear setbacks, and the 25 percent cap on the combined side plus rear yard area. Sketch a simple site plan to see where a footprint will fit. The city’s casita page includes diagrams and a site plan checklist.
- Paradise Hills: verify your exact PHSZD zone and its accessory-building provisions. Where living quarters are allowed, the ordinance often requires a minimum 10 ft separation from the main dwelling and sets area limits. Kitchens trigger different treatment, so clarify your intent early with PHSZD staff.
Arroyos, drainage, and easements
West Side properties commonly sit near mapped arroyos. Both the city and PHSZD can require drainage considerations or engineered plans if you build near these features. Pull your plat or survey and note any drainage or utility easements in the rear yard that may prohibit structures. The PHSZD ordinance outlines arroyo and drainage protections, and PHSZD submittals often require survey documentation.
Utilities and metering
Plan for water and sewer work through ABCWUA, including connection permits, fees, and coordination on meter location and sewer tie-ins. Separate metering for a casita is possible in some cases, but many owners keep the unit on the primary meter. Contact ABCWUA New Construction early for process and fees: ABCWUA New Construction FAQs. Coordinate electrical capacity or a potential new meter with your utility provider, and check gas service if applicable.
Smart design ideas for West Side lots
- Compact studio or one-bedroom, about 450 to 550 sq ft, to fit tighter rear yards and control cost.
- A one-bedroom plus den up to 750 sq ft for more flexibility where the city rules apply.
- A detached garage with a small unit above if depth allows and your zone permits this form.
- Modular or prefab units that shorten build time. Remember to budget for foundation, craning, and utility connections.
- Climate-smart choices: orient for shade, add deep overhangs, consider xeriscaping, and optimize insulation. The city’s free plan sets are a useful starting point for Albuquerque projects.
Permits and process
City of Albuquerque steps
- Confirm your zoning and casita eligibility, then measure yard areas and setbacks against city standards. See the city’s ADU page for what is allowed.
- Prepare and submit a simple site plan showing the house, easements, proposed casita, and parking. Consider starting from the city’s free casita plans.
- Submit for building permits through ABQ-PLAN, including trade permits as needed. Respond to plan review comments.
- Build and schedule inspections through final sign-off.

Paradise Hills steps
- Confirm your PHSZD zone and how it treats accessory living quarters versus a full unit with a kitchen. Kitchens often change the use category and may require a Special Use Permit.
- Complete the PHSZD zoning permit application and fee estimate. Conforming projects may be handled administratively. Nonconforming requests go to a Commission hearing.
- After PHSZD zoning approval, follow directions for building permits and any required surveys or drainage studies.

What it might cost
Detaching a small home in the backyard can be done on a wide range of budgets. Recent national and regional guides suggest:
- Basic, modest detached unit about 400 to 600 sq ft: roughly $80,000 to $200,000.
- Mid-range 500 to 750 sq ft: roughly $150,000 to $300,000.
- High-end or complex sites: $300,000 or more.
A common benchmark is $150 to $400 per sq ft depending on site work, utilities, and finishes. See this overview for context: ADU cost guide.
Key cost drivers include trenching for water and sewer, separate metering, grading or engineered foundations near arroyos, and any fire-rating or separation requirements. Many owners use home equity, a cash-out refinance, or a construction loan. The city’s ADU page notes that conventional financing and home-equity paths are typical in our area.
Quick start checklist
- Identify your jurisdiction: City of Albuquerque or PHSZD in Paradise Hills. This determines what is allowed and who permits it.
- Pull your survey or plat. Mark rear and side yards, and note arroyos, drainage features, and any easements.
- For city lots, run the 750 sq ft, 5 ft setbacks, and 25 percent yard cap tests. For PHSZD, confirm the accessory rules for your zone and whether a kitchen is feasible.
- Call ABCWUA New Construction to discuss water and sewer connections and fees.
- Choose a concept that fits. City projects can leverage free plan sets to save time.
- Build a realistic budget range and timeline. Get at least two local contractor estimates.
