Comparte medidor con la casa principal. $150K-$180K en 2026.

How long do La Puente ADU permits take?

5 to 8 weeks in 2026. The state 60-day ministerial path is being honored for detached ADUs under 800 sq ft but the city has been running closer to 70-80 days due to volume. We submit on day one and follow up weekly.

What rent can a La Puente ADU achieve in 2026?

$2,300 to $2,900 per month for a clean 1-bedroom detached ADU. Tenant pool is steady — medical, warehouse, and service-industry tenants working the San Gabriel Valley corridor. We size and lay out the unit for that market if rental is the goal.

Will the sewer lateral need replacement?

On most 91744 post-war stucco lots, yes. The 60- to 70-year-old lateral cannot handle an ADU load on top of the existing main. We replace it from cleanout to main as part of every detached ADU scope, scoped upfront with camera inspection.

Will I need a panel upgrade?

Almost always yes on original 91744 service. We size to 200 amp at minimum, sometimes 320 or 400 amp if the ADU runs on separate service. All three options priced up front.

Mi lote esta en Old Town La Puente. Hay restricciones especiales?

La Puente no tiene un distrito historico oficial, pero los lotes de Old Town suelen ser mas grandes y con vegetacion madura que respetamos. El zoning es residencial estandar, los setbacks de ADU son los del estado (4 pies del fondo y de los lados). No hay aprobaciones adicionales mas alla del permit normal.

Same project manager from start to finish?

Yes. Bilingual Spanish-fluent PM standard on every La Puente job. Same person from contract day to final inspection — no handoffs.
