Build Your ADU Faster with B & A Construction
B & A Construction proudly helps homeowners navigate pre-approved ADU plan programs offered by participating California cities and counties. If your property is located in an area with an approved ADU program, these plans can help reduce design costs, streamline portions of the permitting process, and move your project into construction more quickly. Even with pre-approved plans, every project still requires site-specific review and building permits, and our team manages that entire process for you.
We assist homeowners with pre-approved ADU plans throughout:
- Sacramento County – Including eligible unincorporated areas participating in the County's Shelf Ready ADU Program.
- City of Sacramento - Homeowners can take advantage of the City's pre-approved ADU program designed to help simplify plan review and permitting.
- San Joaquin County – We help homeowners determine whether their city or jurisdiction offers pre-approved ADU plans and guide them through the permitting and construction process.
- Stanislaus County – Free pre-plan-checked ADU plans are available for qualifying projects within the unincorporated county and participating cities, including Modesto, Turlock, Oakdale, Riverbank, Ceres, and Waterford.
- Fresno County – Both the City of Fresno and Fresno County offer pre-approved ADU plans to encourage new housing and simplify the building process.
- Merced County – We assist homeowners in determining available ADU options, local development standards, and permitting requirements for properties throughout Merced County.
What Are Pre-Approved ADU Plans?
Pre-approved ADU plans are professionally designed construction plans that have already been reviewed and accepted by participating cities or counties. Although every project still requires site-specific review and permits, these plans often reduce plan review time, lower architectural costs, and help homeowners begin construction sooner.
Benefits include:
- Faster permitting
- Reduced design costs
- Streamlined plan review
- Proven architectural layouts
- Faster project timelines
- Increased property value
- Rental income opportunities
- High-quality residential designs
Our team helps determine whether a pre-approved plan is available for your property and manages the permitting process from start to finish.
