Woollard Construction Emerges as Top General Contractor for Temecula Valley ADU Building
As California continues to push municipalities toward faster housing approvals, homeowners across the Temecula Valley are moving quickly to add secondary living space to their properties. Woollard Construction, a local licensed general contractor, has built its reputation over three decades by guiding property owners through the process of constructing an accessory dwelling unit (ADU).
Founded in 1990, Woollard Construction is a recognized California Contractors State License Board company that has completed more than 350 residential projects throughout Temecula, Murrieta, Menifee, Wildomar, Fallbrook and across Southern California. In 2026, citing a combination of new state legislation and updated local permitting workflows that have made the approval process more predictable, the company is expanding its services as a specialist ADU contractor to meet the surging demand for accessory dwelling units.
These legislative updates have accelerated backyard housing development, mitigating housing constraints in California. Three California statutes, Assembly Bill 68, Assembly Bill 881, and Senate Bill 9, have fundamentally altered how ADUs obtain permits across the state. These updates effectively eliminate many owner-occupancy requirements, capping local agency review periods and compressing their plan-check timelines to two to three months for compliant submittals.
Under current Riverside County regulations, residential lots may accommodate a detached ADU of up to 1,200 square feet, an attached unit, a garage conversion, or a junior ADU (JADU) of up to 500 square feet built within the existing footprint of the primary home, with distinct requirements for setbacks, utility connections, foundation type, and California Title 24 energy efficiency compliance. As a specialist ADU contractor, Woollard Construction addresses the distinct logistical parameters governing these regulations, strictly adhering to regional setback mandates, infrastructure integration, and California Title 24 energy-efficiency compliance measures.
“Building ADUs has become more in demand than at any point in our 35-year history. By consolidating architectural, engineering, utility alignment, and compliance requirements under a single management team,we eliminate issues traditionally associated with multi-tiered subcontracting. From design to final inspection, we build right the first time,” said company founder Spencer Woollard.

Errors during the pre-construction phase can trigger costly redesigns or extended delays, as setback lines, utility capacity, soil classification, and grading requirements vary considerably across communities such as Wine Country, Santiago Estates, Meadowview, Morgan Hill, Bear Creek, and Butterfield. By verifying utility capacities and submitting code-compliant plans during the initial check, Woollard Construction mitigates the risks of project stagnation during municipal review.
At Woollard Construction, financial transparency remains a core tenet of its client engagement policy, using fixed-bid pricing models rather than variable estimates to shield property owners from sudden material or administrative cost escalations.
Typically, base expenses fluctuate, depending on final square footage, grading, and material specifications. A garage conversion represents the entry point for permitted development, while a fully detached residential structure occupies the higher end of the pricing spectrum.
