Frequently Asked Questions About ADU Construction with TheADUPro
General ADU Questions
Q: What is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can be detached structures, attached additions, or conversions of existing space like garages. They include complete living facilities including kitchen, bathroom, and sleeping areas. ADUs are sometimes called granny flats, in-law units, backyard cottages, or casitas.
Q: Why should I build an ADU?
ADUs offer numerous benefits including:
- Rental Income: Generate passive income by renting the unit long-term or as a vacation rental
- Multigenerational Living: House aging parents, adult children, or extended family while maintaining privacy
- Property Value: Increase your property’s market value significantly
- Flexible Space: Create a home office, art studio, gym, or guest house
- Housing Solution: Address California’s housing shortage while benefiting personally
- Aging in Place: Create accessible living space for future needs
Q: How much does it cost to build an ADU with TheADUPro?
ADU costs vary based on size, design complexity, site conditions, and finish selections. Generally, costs range from $150,000 to $400,000+ for complete turnkey projects. TheADUPro’s competitive pricing ensures you receive maximum value. During your free consultation, we’ll provide a detailed estimate based on your specific project parameters. Remember, we also offer financing options through our lending partners to make your ADU project affordable.
Q: How long does it take to build an ADU?
Typical ADU projects take 6-12 months from initial consultation to move-in ready completion. This timeline includes:
- Design and planning: 4-8 weeks
- Permitting: 6-16 weeks (varies by jurisdiction)
- Construction: 16-24 weeks
TheADUPro’s experience and efficient processes help minimize delays and keep projects on schedule.
Q: Do I need special permits to build an ADU?
Yes, ADUs require building permits from your local jurisdiction. TheADUPro handles all permitting requirements, including plan submission, plan check coordination, and permit acquisition. California’s recent ADU laws have streamlined the permitting process, and our expertise ensures compliance with all requirements.

Design and Planning Questions
Q: Can I customize my ADU design?
Absolutely! TheADUPro offers fully customized ADU designs tailored to your preferences, property characteristics, and intended use. Our design team works closely with you to create an ADU that matches your vision while maximizing functionality and value.
Q: What size ADU can I build on my property?
ADU size limitations depend on local zoning regulations and your property characteristics. California law generally allows ADUs up to 1,200 square feet, though specific jurisdictions may have different requirements. TheADUPro conducts thorough site evaluations to determine your property’s ADU potential and ensures compliance with all applicable regulations.
Q: Can TheADUPro convert my existing garage into an ADU?
Yes! Garage conversions are one of our specialties. Converting an existing garage into an ADU often provides cost savings compared to new construction while creating beautiful, functional living space. We handle all aspects including structural modifications, utility installations, and interior finishes.
Q: What utilities does an ADU need?
ADUs require connections to:
- Electrical service (may require panel upgrade)
- Water supply
- Sewer or septic system
- Gas service (if applicable)
- Internet/cable (optional)
TheADUPro coordinates all utility connections and ensures adequate capacity for both your main house and new ADU.
Q: Can I build a two-story ADU?
Yes, two-story ADUs are allowed in many jurisdictions and can be an excellent solution for maximizing square footage on smaller lots. TheADUPro designs and builds two-story ADUs that comply with height restrictions and setback requirements while creating spacious, functional living environments.
Construction Process Questions
Q: Will ADU construction disrupt my daily life?
TheADUPro minimizes disruption through careful planning, professional crews, and respectful construction practices. While some noise and activity are unavoidable during construction, we maintain clean job sites, establish convenient access routes, and schedule noisy work during reasonable hours. Most homeowners continue their normal routines with minimal inconvenience.
Q: What happens if there are problems during construction?
TheADUPro’s experienced team proactively identifies and addresses potential issues before they become significant problems. If unexpected conditions arise (unusual soil conditions, hidden utilities, etc.), your project manager immediately communicates the situation, presents solutions, and discusses any cost or schedule implications before proceeding.
Q: Can I make changes during construction?
Minor changes are often possible, though they may affect project timeline and cost. TheADUPro’s project managers work with you to evaluate change requests and provide accurate assessments of implications. We recommend finalizing all design decisions before construction begins to avoid delays and additional costs.
Q: Does TheADUPro handle inspections?
Yes! TheADUPro schedules and coordinates all required building inspections throughout the construction process. Our experienced crews know exactly what inspectors look for, ensuring smooth inspections and minimal corrections. We handle all communication with building departments and ensure your ADU passes all inspections.
Financial and Legal Questions
Q: Will building an ADU increase my property taxes?
Yes, adding an ADU typically increases your property’s assessed value, resulting in higher property taxes. However, the rental income potential or other benefits often far outweigh the tax increase. California’s Proposition 13 limits how much your assessed value can increase. Consult with a tax professional for specific guidance regarding your situation.
Q: Can I rent out my ADU?
In most California jurisdictions, yes! ADUs can be rented long-term or as short-term vacation rentals (subject to local regulations). Many homeowners build ADUs specifically for rental income. Some jurisdictions require owner occupancy of either the main house or ADU. TheADUPro can provide guidance on local rental regulations during your consultation.
Q: Do I need HOA approval to build an ADU?
If your property is in an HOA community, you typically need HOA approval before building an ADU. However, California law (AB 670) limits HOA authority to deny ADUs that comply with local building standards. TheADUPro can assist with HOA approval processes, though we recommend consulting your HOA documents and potentially an attorney familiar with California ADU laws.
Q: What warranties does TheADUPro provide?
TheADUPro provides comprehensive warranties covering workmanship and materials. Specific warranty terms are detailed in your construction contract. Additionally, many materials and systems (roofing, appliances, HVAC) include manufacturer warranties. We provide all warranty documentation at project completion.
