San Diego Plumbing for ADUs & New Builds: What Congress’ 21st Century ROAD to Housing Act Could Mean for Faster Housing in California

Congress is taking a rare bipartisan step to address America’s housing shortage, and the 21st Century ROAD to Housing Act is being widely welcomed as momentum in the right direction. But as a recent commentary in San Diego points out, even strong federal action can only go so far when the biggest obstacles to building homes in California are rooted in state and local approval delays.

For San Diego County, where housing demand remains high and affordability continues to strain working families, this matters in an immediate, practical way: more homes typically mean more infrastructure needs, including water, sewer, gas, and modern plumbing systems that can support denser development, ADUs, townhomes, and multi-family housing.

Why federal housing momentum still hits a California wall

Who is driving the conversation

The Times of San Diego commentary was authored by Aimee Faucett, Chief Executive Officer of the Building Industry Association of San Diego County. Her core argument is straightforward: federal reforms may help, but California’s housing bottlenecks are often created by lengthy state and local review and permitting processes.

What happened and what the bill aims to do

The bipartisan 21st Century ROAD to Housing Act is positioned as a federal effort to help the country build more homes by reducing friction points that slow development. In a national environment where major legislation often stalls, the bill stands out as an example of Congress trying to increase housing supply.

Where the impacts are being debated

Locally, the discussion is especially relevant in San Diego, where constrained housing inventory contributes to higher rents, rising home prices, and longer commutes. Even if federal policy improves financing, incentives, or administrative pathways, housing projects in California can still be delayed for years by local process and review requirements.

When this becomes a voter issue in California

The commentary highlights a near-term California flashpoint: Proposition 45 (appearing on the November ballot) as a potential tool to modernize project review and permitting while keeping environmental protections in place. The piece cites that permitting and approval delays can add more than $75,000 to the cost of a new home—costs that typically flow downstream to buyers and renters.

Why it matters for housing affordability in San Diego

The central affordability message is that supply is not keeping pace with demand. When housing projects stall, the consequences are predictable: higher prices, limited options, and fewer pathways to stable housing for working families. In San Diego and across California, speeding up responsible construction is increasingly viewed as a key lever to improving affordability.

What this housing push means for plumbing, ADUs, and renovations in San Diego

As California tries to build “more housing of every kind”—including apartments, townhomes, accessory dwelling units (ADUs), and single-family homes—plumbing becomes a critical enabling trade. Every new unit needs compliant water supply lines, drainage, venting, sewer connections, gas piping (when applicable), and water heater solutions that meet code and perform reliably.

In San Diego, housing expansion often involves a mix of:

1) New construction and multi-unit development that may require larger service lines, new sewer laterals, and complex pressure and drainage engineering; and

2) ADUs and remodels that rely on tying into existing plumbing systems—sometimes systems that were never designed for added fixtures, added occupants, or modern water demands.

When permitting accelerates, timelines compress. That can be good news for housing delivery, but it also raises the stakes for choosing the right plumbing contractor and planning the job correctly. Poorly designed or rushed plumbing work can trigger inspection failures, costly rework, water damage, mold risk, and project delays that erase the savings gained from faster approvals.

A plumber’s perspective: the hidden risk in “build faster” housing goals

Speed is important—but so is durability. In practice, faster development cycles can increase the risk of:

• Undersized drain lines or improper venting that cause chronic backups

• Improper tie-ins to older sewer laterals, leading to leaks or root intrusion issues

• Water pressure problems in multi-unit or stacked layouts

• Unpermitted or non-code work that becomes a problem at resale, inspection, or insurance claim time

San Diego’s housing future will depend not just on policy, but on execution. Reliable plumbing infrastructure is what makes added housing livable, safe, and sustainable—especially in ADU-heavy neighborhoods and infill development areas where existing systems may be decades old.

How Fraser Plumbing of San Diego supports housing growth the right way

As homeowners, landlords, builders, and property managers navigate California’s evolving housing landscape, plumbing is often one of the most consequential scopes of work. Fraser Plumbing of San Diego helps local customers plan, upgrade, repair, and install plumbing systems that can meet modern demand—whether the project is an ADU build, a remodel to add units, or a repair that prevents costly water damage.

When housing supply expands, plumbing needs often expand with it. That can include:

• Sewer line inspections and replacements for older properties

• Water line upgrades to support added bathrooms, laundry, or kitchens

• Water heater installations (including tankless options where suitable)

• Fixture additions and re-pipes tied to remodels and unit conversions

• Leak detection and emergency repairs that protect the property during construction or occupancy changes

San Diego homeowners and builders: practical steps to avoid plumbing delays and cost overruns

If California’s permitting environment changes and more projects move forward faster, the best way to protect your schedule and budget is to reduce avoidable surprises in the walls, slab, and yard.

Actionable takeaways

• Schedule a plumbing assessment early, especially for ADUs and additions, to confirm the existing system can handle added demand.
• Inspect sewer laterals on older San Diego properties before construction begins to avoid backups, collapses, or root intrusion during the project.
• Confirm code-compliant venting and drain sizing in multi-bath layouts to prevent slow drains and recurring clogs after move-in.
• Don’t rush tie-ins: improper connections are a common cause of leaks, failed inspections, and expensive rework.
• Plan for water heating capacity (tank or tankless) based on the final number of occupants and fixtures, not just what the house had historically.
