1. How does the design-build home renovation process work in California?

With Urbatect’s design-build model, we manage your entire project under one contract—design, permitting, and construction. This means fewer delays, better communication, and a smoother experience for California homeowners looking for ADU, remodel, expand, or build a home.

2. How can I keep my home renovation or ADU project on budget in California?

Urbatect offers a fixed-price contract early in the design phase. Our design and construction teams work together from day one to align your vision and your budget—so you don’t face last-minute costs, change orders, or surprises during construction.

3. Do I need a permit to remodel my home, add a room, or build an ADU in California?

Yes, almost all remodeling, additions, and ADU projects in California require city permits. Urbatect handles the full permitting process—from planning, drawings and city submittals to construction—so your project stays compliant and on track.

4. Is it better to hire a design-build firm or separate professional or contractor in California?

Working with a design-build firm like Urbatect gives you one team handling everything. That means better coordination, fewer delays, and more control over your budget—unlike hiring a separate architect, engineer, and contractor who may not be aligned.

5. What’s the best option for my property: build an ADU, add a room, or remodel my home in California?

It depends on your space, budget, and long-term goals. Urbatect offers a custom feasibility study to help you decide. Whether you need more living space, rental income, or a layout upgrade—we’ll help you choose the right solution for your home and property.

6. How long does a home remodel, room addition, or ADU project take in California?

Project timelines vary, but most remodels and ADUs in California take between 3 to 12 months. Urbatect’s all-in-one approach helps speed things up—we handle design, permits, and construction in-house so you avoid unnecessary delays.

7. Can I hire Urbatect just for design services, or do you have pre-approved ADU plans?

Yes. We offer both custom design services and build ready ADU plans ready for permits. Whether you want a fully customized layout or a faster, more affordable plan, we help you choose what works best for your property and timeline.

Detached ADU

A Detached Accessory Dwelling Unit (ADU) is a standalone structure, built independently from your main house and any other buildings on your lot. This offers maximum privacy and flexibility, perfect for rental income, guest accommodations, a home office, or multi-generational living.

Attached ADU

While an Attached Accessory Dwelling Unit (ADU) integrates with your existing home by sharing a wall, it's important to understand its independent nature. Unlike a simple extension, an attached ADU operates as a self-contained living space with its own private entrance. This ensures clear separation and privacy between the main house and the ADU.

Garage Conversion / Junior ADU (J-ADU) / ADU Over Garage

Your garage holds untapped potential! Converting it into a self-contained living space is a smart way to add value and flexibility to your property. Often, garage conversions fall under the category of an Accessory Dwelling Unit (ADU). When this conversion stays within the existing footprint of your single-family home, it might be classified as a Junior ADU (JADU). JADUs often have specific size limitations set by local ordinances and can be a cost-effective way to create an independent unit for family, guests, or even rental income. We can help you navigate the possibilities and determine if a JADU conversion is the right fit for your needs.

Basement & In-Law Unit Transformations

Have an underused basement or an existing in-law unit in your home? These are prime candidates for Accessory Dwelling Unit (ADU) conversions! Let us help you reimagine these spaces into comfortable, self-contained living areas. Whether you need extra income, guest accommodations, or a solution for multi-generational living, we'll handle the design and build process to create a valuable ADU that meets local requirements.
